The Delta launch vehicle was America's longest-lived, most reliable, and lowest-cost space launch vehicle. Development began in 1955 and it continued in service in the 21st Century despite numerous candidate replacements.

Delta began as Thor, a crash December 1955 program to produce an intermediate range ballistic missile using existing components, which flew thirteen months after go-ahead. Fifteen months after that, a space launch version flew, using an existing upper stage. The addition of solid rocket boosters allowed the Thor core and Able/Delta upper stages to be stretched. Costs were kept down by using first and second-stage rocket engines surplus to the Apollo program in the 1970's. Continuous introduction of new 'existing' technology over the years resulted in an incredible evolution - the payload into a geosynchronous transfer orbit increasing from 68 kg in 1962 to 3810 kg by 2002. Delta survived innumerable attempts to kill the program and replace it with 'more rationale' alternatives. By 2008 nearly 1,000 boosters had flown over a fifty-year career, and cancellation was again announced.

The Delta space launch family had its roots in the Thor IRBM. Thor was a 2400 km range missile with essentially the same characteristics as the Army's Jupiter. It was developed by Douglas Aircraft in one of the most accelerated crash programs in history. 'Chief Designer' of the Thor was Jack Bromberg. He was not educated formally as an engineer, but was smart and dynamic. Company owner Donald Douglas had hired him back in the 1930's. He was a major influence in Douglas' winning response to the USAF request for proposal, which emanated from USAF Missile Czar General Bernard Schriever.

The Air Force requirement was to build an IRBM around a discarded rocket motor design. The engine had been developed as the sustainer engine for the Atlas missile when the requirement was to launch a 2700 kg thermonuclear warhead over an intercontinental range. When it became apparent that the warhead could be reduced to less than half that weight, the Atlas was downsized, and the 68 tonne thrust sustainer motor was no longer required.

Douglas flew a first prototype only thirteen months after go-ahead. Sixty Thors were deployed to missile sites in Great Britain under Project Emily. After a few years the Thors were withdrawn from Britain (and the Jupiters from Turkey) as part of the secret codicil of Kennedy's deal to end the Cuban Missile Crisis. A few continued in an offensive military role as a nuclear-tipped anti-satellite system, based on Johnson Atoll in the Pacific, until the end of the early 1970's. Surplus Thors were used for a variety of suborbital re-entry vehicle tests.

After the Sputnik shock, all available assets were pressed into service. Thor was developed into a workhorse for the space program. The Able stage developed for the Vanguard project was mated to the Thor. A fundamental problem was that the thrust to weight ratio of the basic vehicle left little margin for growth or larger upper stages. This was solved by using Castor solid rockets strapped to the base of the vehicle to increase the lift-off thrust. Almost by accident rather than design, Thor developed into the Delta, the standard American medium-lift launcher, continually evolving through the use of more and larger strap-on boosters, a cylindrical and stretched core, and enlarged upper stages. The original Aerojet Able upper stage evolved into the Delta. From 1959-1972 the US Air Force and NASA flew versions of the launch vehicle using the same core and solid booster technology, but with the Agena upper stage rather than the Delta. After going through a bewildering myriad of military versions it emerged as the standardized, reliable and economical Delta commercial satellite launch vehicle by the mid-1970's. Improved Delta versions continued in production into the next millennium, with nearly 1,000 airframes completed, and the end of production announced yet again in 2008.

The innumerable 'deaths' and resurrections of the Delta are described in Aerojet - The Creative Company, 1995:

Using NASA terminology, their first Delta launch vehicle was basically an Air Force Able consisting of a Thor first stage, an Able second stage, and a solid propellant third stage of nominally 2760 lbf thrust produced by Allegheny Ballistics Laboratory (ABL). These vehicles and their powerplants are discussed above as part of the Able family. The first NASA contracts for these upper stages were in 1959, deliveries began in 1961, and numerous additional contracts followed. Also in 1961, NASA shifted to the Ablestar configuration. The first launch using this configuration occurred on May 13, 1960 and, according to one source on NASA history, did not reach orbit because of a malfunction in the Aerojet stage. Aerojet's findings indicate that it never got the signal to fire. The second attempt on August 12, 1960 was successful, and these engines were used until years later when the more powerful Air Force Delta second stage ablative engines became available.

At this point the Air Force, realizing the need for a larger space launch capability separate from the civilian efforts, selected the concept of using both stages of Titan II with various third and fourth stages, and later an array of zero stages. In very general terms, they retained the Agena for Thor and Atlas upper stages, and sought a new larger and simpler third stage, which was called Transtage. Agena was, however, regularly used on both Thor and Titan lower stages, and was often favored because it was a pump fed unit and was much lighter. The desirability of low chamber pressure, ablative chambers and a pressurized propellant feed system had been demonstrated in Vanguard, Hydra, and Ablestar, which led to the selection (for Titan) of the Transtage configuration using two chambers similar to, but larger than Ablestar. A variation of this became known as the Improved Delta stage, and was used extensively on Thor -so much so that the vehicle became known as Thor/Delta, and in some cases, only as Delta, or later as Thrust Augmented Delta, Long Tank Delta, Delta - PAM, and similar versions.

The resulting (improved) Delta launch vehicle underwent a bewildering succession of changes in configuration and performance (some incremental and some extensive) which is continuing to this day. All three stages have undergone upratings and replacements with more powerful engines, and there has been a succession of increasing numbers and sizes of strap-on solid propellant rocket zero stages. Aerojet's original ablative Delta engine had a radiation cooled nozzle exit section, burned N2O4/Aerozine-50 and produced a vacuum thrust of 9000 lbf. This unit also underwent several modifications, ending up with a thrust of 10,200 lbf, and a variety of tank sizes. A throttling (variable thrust) version was developed for a Navy application, and the Delta family could be generally distinguished from Transtage engines by the fact that the Delta gimbal point was at the head end (above the valve assembly), while the Transtage engines (in addition to being smaller) gimballed at the plane of the nozzle throat.

In the early 1970s the expendable launch business was going quite well technically, but changes to reduce cost and increase payload were examined continuously. A series of Delta Alternative Studies was made, some being funded by NASA, but mostly in-house. One such study by Aerojet explored the concept of using a single barrel of the LR-87 engine. This would be used to improve Delta performance, but sufficient development funds were not available and the shuttle was receiving all the emphasis, so the idea died. Another of these studies involved the use of liquid boosters in place of the nine solid boosters then attached to the Thor as a zero stage. The concept was to use either storable or LOX/RP-1 single LR-87 thrust chambers, pressure fed from filament wound tanks. The tanks would use thin metal liners to ensure freedom from leakage - as is still required today for high pressure, light weight filament wound vessels. Aerojet's solid rocket division had done some very encouraging work on high performance solid rocket engine chambers of this same type, and the prices were very attractive. The Aerojet team: Wally Dinsmore, Bob Frew, Lynn Meland. Howard Williams, and Chris Harlambakis from our Los Angeles office had many meetings and technical discussions at Huntington Beach. Two were memorable. The first was in October 1987 when their hosts kept slipping out of the meeting to check their stocks - this was the day the stock market fell drastically. No decisions were made that day. The second meeting almost didn't start. When the Aerojet contingent arrived, there was no one in the building because of an earthquake. The meeting finally got going, and just as Wally was to give his punch line cost and schedule estimate, the building shook with a severe aftershock and plaster dust fell from the ceiling. There were no decisions made that day either. This concept, like the others, couldn't get over the hurdle of the initial development cost - and probably the image of starting up a major new booster program.

Some additional insights into the early part of NASA's long succession of changes are provided by Dan Dembrow, who worked for NASA on the Delta Program at Goddard Space Flight Center:

The Delta launch vehicle was always viewed as an interim launch vehicle in NASA's stable, and was used to retain an intermediate size orbital payload capability until larger launch vehicles were developed. The Delta Project Manager at NASA, Bill Schindler, had a knack for keeping the program alive. He would participate in the launch vehicle assignment process, and when he found that Headquarters was about to kill the Delta on the grounds that a new mission exceeded its capabilities, he would assure them that Delta could do the job. Then he would challenge his technical staff, and often with the aid of the prime contractor, McDonnell Douglas, and our Goddard technical staff, to figure out a way to extend the flight envelope. This process occurred many times, and it was extremely difficult as production launch vehicles are not meant to undergo such constant changes in design. Delta payloads grew from about 200 lbm in low earth orbit in 1960 to about 4100 lbm in geosynchronous orbit by 1990.

In the 1960s, Goddard contracted directly for many of the components (including the second stage from Aerojet), and supplied them to McDonnell Douglas as government furnished equipment (GFE). During this period, Schindler oversold what Delta could do, and each successive payload had us in a quandary. Aerojet was always ready to test changes that would increase the second stage total impulse, and did so frequently. In one such case, a special test was required, and Aerojet went to a lot of trouble to upgrade the test stand for display to NASA management. Among the improvements was a new fail-safe system, and they even went to the point of repainting the bay. At the scheduled date the NASA managers had a schedule conflict, so I was the only NASA observer.

The test took place as scheduled, the instrumentation performed flawlessly, the test values were all nominal, and suddenly the test ended unexpectedly in mid-duration. Nothing within the control room showed anything wrong. When we went out into the test bay, the newly painted walls were on fire. The heat from the fire must have damaged some wiring in the fail-safe system, which promptly terminated the firing.

Aerojet did not realize the critical nature of the test, and this failure almost inadvertently killed the Delta program. Fortunately I was the only NASA observer, and a re-test was successfully conducted within a few days, so Schindler by that time was able to persuade NASA management that all was well. The critical decision was made to fly the mission on Delta.

The customary tug-of-war between the overall vehicle contractor and component system supplier over who should supply how much of the product, began as might be expected. As long as the project remained in Azusa, we had been able to keep the costs below anything Douglas could match. However, at the time when it was to be moved to Sacramento, management required the use of the "new" Commitment Proposal Estimating System which resulted in higher estimated costs. Also, the Douglas Huntington Beach plant was extremely low on work. As a final touch, Aerojet solved the problem by arrogantly sticking to the much higher price to our customer (Douglas). They promptly responded by replacing our system with a similar unit from TRW (surplus LM units) that unfortunately had slightly lower performance. Most of the production for NASA in that time period continued with this TRW engine. Douglas also had kept wearing away Aerojet's share of the project so that we went from supplying the complete stage to the present status of supplying only the thrust chamber assembly and propellant feed lines.

After a painful hiatus, we began work in 1975 on a complete "Fat Delta" stage for the Japanese N-II launch vehicle. At this point we received Air Force funding for performance improvement, one element of which was called the Delta I.T.I.P. (Improved Transtage Injector Program), and used an improved curved face, baffled injector. A still higher performance unit was developed, using a flat faced, baffled injector, and these were used in a two barrel configuration for a classified program. Their excellent performance made this chamber configuration popular, and was the basis for a long but relatively modest rate.

The Delta 3 introduced a new cryogenic upper stage in 1998. However the vehicle began tests just as the satellite market collapsed. It was flown only three times, two of the launches being failures. Meanwhile the most numerous and successful version, the Delta 7000 series, continued in service. The completely new-design Delta 4 was supposed to replace it in service, but the Delta 7000 remained not only lower cost but the most reliable launch vehicle produced in the United States. Nevertheless, in 2008, it was announced that production would be terminated and the Delta 4 would replace it.

The configuration of Delta vehicles was encoded for forty years as follows:

  • First digit: basic vehicle configuration:

    This was defined up to 2004 as follows:

    • 0 = Castor 2 solid propellant strap-ons, Long Tank Thor core with MB-3 engine
    • 1 = Castor 2 strap-ons, Extended Long Tank core with MB-3 engine
    • 2 = Castor 2 strap-ons, Extended Long Tank core with RS-27 engine (derived from surplus H-1 engines of the Saturn IB).
    • 3 = Castor 4 solid propellant strap-ons, Extended Long Tank core with RS-27 engine
    • 4 = Castor 4A strap-ons, Extended Long Tank core with MB-3 engine
    • 5 = Castor 4A strap-ons, Extended Long Tank core with RS-27 engine
    • 6 = Castor 4A strap-ons, Extra Extended Long Tank core with RS-27 engine
    • 7 = GEM-40 solid propellant strap-ons, Extra Extended Long Tank core with RS-27A engine
    • 8 = GEM-46 solid propellant strap-ons, Delta-3 strengthened Extra Extended Long Tank core with RS-27A engine
    • 9 = GEM-60 solid propellant strap-ons, Delta-4 Lox/LH2 cryogenic core with RS-68 engine.

    After 2004 this was revised to:

    • 2 = Delta II first stage (previously Delta 6000 and 7000 series)
    • 3 = Delta III first stage (previously Delta 8000 series)
    • 4 = Delta IV first stage (previously Delta 9000 series)

  • Second digit: Number of solid propellant strap-ons (0, 3, or 9 prior to Delta IV. 0, 2, or 4 for Delta-4).

  • Third digit: Second stage

    • 0 = Delta storable propellant stage with AJ10-118 series engines
    • 1 = Delta storable propellant stage with TR-201 engines (surplus TRW Apollo Lunar Module upper stage engines)
    • 2 = Delta K storable propellant stage with AJ10-118K engine
    • 3 = Delta-3 Lox/LH2 cryogenic upper stage with RL10B-2 engine
    • 4 = Delta-4 Lox/LH2 cryogenic upper stage with 4 m diameter
    • 5 = Delta-4 Lox/LH2 cryogenic upper stage with 5 m diameter

  • Fourth digit: Third stage

    • 0 = No third stage
    • 1 = Not used
    • 2 = Not used
    • 3 = Star 37D / TE-364-3 solid propellant kick stage
    • 4 = Star 37E / TE-364-4 solid propellant kick stage
    • 5 = Star-48B / PAM-D solid propellant kick stage (often listed as '0' upper stage with a PAM-D due to the modular nature of the PAM configuration).
    • 6 = Star 37FM solid propellant kick stage
  • Optional letter after fourth character: An 'H' here indicated a 'Heavy' configuration. For Delta II, this was use of 46 inch diameter GEM solid strap-on motors in place of the standard Castor motors. For Delta IV, it indicated use of two strap-on Common Booster Cores (CBC) to supplement the CBC on the core stage.
  • Dash number: Payload fairing. For Delta II, this indicates the diameter of the fairing in feet. For Delta III or Delta IV, it indicates the length of the fairing in meters.

Associated Launch Vehicles
  • Thor American liquid propellant intermediate range ballistic missile, developed by Douglas in 1956-1958. 60 deployed to Britain in 1958-1962. The basis for a family of Thor and Delta space launch vehicles, remaining in production into the 2010's. More...
  • Delta American orbital launch vehicle. The Delta launch vehicle was America's longest-lived, most reliable, and lowest-cost space launch vehicle. Delta began as Thor, a crash December 1955 program to produce an intermediate range ballistic missile using existing components, which flew thirteen months after go-ahead. Fifteen months after that, a space launch version flew, using an existing upper stage. The addition of solid rocket boosters allowed the Thor core and Able/Delta upper stages to be stretched. Costs were kept down by using first and second-stage rocket engines surplus to the Apollo program in the 1970's. Continuous introduction of new 'existing' technology over the years resulted in an incredible evolution - the payload into a geosynchronous transfer orbit increasing from 68 kg in 1962 to 3810 kg by 2002. Delta survived innumerable attempts to kill the program and replace it with 'more rationale' alternatives. By 2008 nearly 1,000 boosters had flown over a fifty-year career, and cancellation was again announced. More...

Decay Date: 1959-04-26 . USAF Sat Cat: 14 . COSPAR: 1959-Gamma-1. Apogee: 346 km (214 mi). Perigee: 239 km (148 mi). Inclination: 89.9000 deg. Period: 90.40 min. KH-1 prototype; tested capsule recovery techniques; did not carry camera; capsule recovery failed. Because of a timing error, the US believed that the capsule landed somewhere on the island of Spitsbergen, north of Norway, instead of landing in the recovery zone near Hawaii. The capsule was never found; and CIA officials suspect it may have been snatched by the Soviets. The search for this capsule formed the basis of the book and film 'Ice Station Zebra'.

    In the winter of 1960/1961, a US Discovery spy satellite capsule was found by loggers near Kalinin, 200 km north of Moscow. The loggers cracked it open with an axe. Sergei Khrushchev believed this to be the Discoverer 2 capsule. What was left was examined by Soviet engineers but didn’t reveal much information - it was a polished aluminium sphere, 30 cm in diameter, gilded on the exterior. Some said it was found as early as the winter of 1959.

COSPAR: 1961-Eta-1. Apogee: 225 km (139 mi). Perigee: 135 km (83 mi). Inclination: 28.4000 deg. Period: 88.10 min. Lofti 1 piggyback payload did not separate. Nevertheless Transit 3B returned useful data needed for design of the operational satellites. It carried a digital clock driven by the same oscillator that drove the transmitters. It transmitted timing signals governed by the clock and a 384-bit memory. This allowed testing of the techniques for loading the memory from the ground, the ability of the memory to hold a message in orbit, and the ability to encode the memory contents by means of a frequency modulation on one of the main transmitters. It was also shown that ±60° phase modulation could be used to transmit the contents of the satellite memory without degradation of the accuracy of the Doppler signal and Doppler measurements.

  • STARFISH PRIME Nuclear test - . Nation: USA. Agency: USAF. Apogee: 400 km (240 mi). Successful high-altitude test of a Thor IRBM with a live nuclear warhead. The payload included test instrumentation and a W-49 warhead/Mk-4 re-entry vehicle. The 1.45 megaton bomb exploded at an altitude of 400 km. The explosion was visible 2,600 km away, at Kwajalein Atoll; an artificial aurora lasted seven minutes. The unforeseen and most militarily significant effect was the electromagnetic pulse (EMP) generated by the test. This caused power mains surges in Oahu, knocking out street lights, blowing fuses and circuit breakers, and triggering burglar alarms (and this in the days before microelectronics). The explosion supercharged the Van Allen radiation belts, resulting in several satellites malfunctioning.

  • OGO 2 - . Payload: OGO C (S-50). Mass: 507 kg (1,117 lb). Nation: USA. Agency: NASA Greenbelt. Class: Earth. Type: Magnetosphere satellite. Spacecraft: OGO. Decay Date: 1981-09-17 . USAF Sat Cat: 1620 . COSPAR: 1965-081A. Apogee: 1,515 km (941 mi). Perigee: 419 km (260 mi). Inclination: 87.4000 deg. Period: 104.40 min. OGO 2 was a large observatory instrumented with 20 experiments designed to make simultaneous, correlative observations of aurora and airglow emissions, energetic particles, magnetic field variations, ionospheric properties, etc., especially over the polar areas. Soon after achieving orbit, difficulties in maintaining earth lock with horizon scanners caused exhaustion of attitude control gas by October 23, 1965, 10 days after launch. At this time, the spacecraft entered a spin mode (about 0.11 rpm) with a large coning angle about the previously vertical axis. Five experiments became useless when the satellite went into this spin mode. Six additional experiments were degraded by this loss of attitude control. By April 1966, both batteries had failed, so subsequent observations were limited to sunlit portions of the orbit. By December 1966, only eight experiments were operational, five of which were not degraded by the spin mode operation. By April 1967, the tape recorders had malfunctioned and only one third of the recorded data could be processed. Spacecraft power and periods of operational scheduling conflicts created six large data gaps so that data were observed on a total of about 306 days of the 2-yr, 18-day total span of observed satellite data to November 1, 1967. The spacecraft was shut down on November 1, 1967, with eight experiments still operational. It was reactivated for 2 weeks in February 1968 to operate the rubidium vapor magnetometer experiment.

  • Explorer 29 - . Payload: GEOS A. Mass: 175 kg (385 lb). Nation: USA. Agency: NASA Greenbelt. Program: Explorer. Class: Astronomy. Type: Solar astronomy satellite. Spacecraft: GEOS. USAF Sat Cat: 1726 . COSPAR: 1965-089A. Apogee: 2,269 km (1,409 mi). Perigee: 1,120 km (690 mi). Inclination: 59.4000 deg. Period: 120.30 min. The primary objective of GEOS-A was to provide global geodetic measurements for determining the positions of fiducial control points on the Earth to an accuracy of 10 meters in an Earth centre of mass co-ordinate system, and to determine the structure of the Earth's gravity field to 5 parts in 10 million. Instrumentation included (1) four optical beacons, (2) laser reflectors, (3) a radio range transponder, (4) Doppler beacons, and (5) a range and range rate transponder. These were designed to operate simultaneously to fulfil the objectives of locating observation points (geodetic control stations) in a three dimensional earth centre-of-mass co-ordinate system within 10 m of accuracy, of defining the structure of the earth's irregular gravitational field and refining the locations and magnitudes of the large gravity anomalies, and of comparing results of the various systems onboard the spacecraft to determine the most accurate and reliable system. In January 1967, a failure in the satellite's command system rendered several geodetic systems inoperable. Radio doppler measurements and the passive laser reflector experiment could continue indefinitely, however. Additional Details: here....

The Westinghouse Aerospace Division, under contract to National Aeronautics and Space Administration's Goddard Space Flight Center, engaged in the system design, integration, assembly and launch support for Anchored Interplanetary Monitoring Platform Satellite, officially designated Explorer 35 by the National Aeronautics and Space Administration. It was launched on July 19, 1967, with the primary objectives of investigation of interplanetary plasma and the interplanetary magnetic field out to and at the lunar distance, in either a captured lunar orbit or a geocentric orbit of the earth. In the geocentric orbit, the apogee was near or beyond the lunar distance. In a lunar orbit, additional objectives included obtaining data on dust distribution, lunar gravitational field, ionosphere, magnetic field, and radiation environment around the moon. AIMP-E also studied spatial and temporal relationships of geophysical and interplanetary phenomena simultaneously being studied by several other National Aeronautics and Space Administration satellites. The investigation in the vicinity of the moon provided for measurements of the characteristics of the interplanetary dust distribution, solar and galactic cosmic rays, as well as a study of the magnetohydrodynamic wake of the earth in the interplanetary medium at the lunar distances.

OGO 4 was a large observatory instrumented with experiments designed to study the interrelationships between the aurora and airglow emissions, energetic particle activity, geomagnetic field variation, ionospheric ionization and recombination, and atmospheric heating which take place during a period of increased solar activity. After the spacecraft achieved orbit and the experiments were deployed into an operating mode, an attitude control problem occurred. This condition was corrected by ground control procedures until complete failure of the tape recording systems in mid-January 1969. At that time, due to the difficulty of maintaining attitude control without the tape recorders, the attitude control system was commanded off, and the spacecraft was placed into a spin-stabilized mode about the axis which was previously maintained vertically. In this mode, seven of the remaining experiments were turned off since no meaningful data could be observed by them. On October 23, 1969, the satellite was turned off. It was reactivated again in January 1970 for 2 months to obtain VLF observations.

The scientific payload, consisting of 13 select biology and radiation experiments, was exposed to microgravity during 45 hours of Earth-orbital flight. Experimental biology packages on the spacecraft contained a variety of specimens, including insects, frog eggs, microorganisms and plants. The planned three-day mission was recalled early because of the threat of a tropical storm in the recovery area, and because of a communication problem between the spacecraft and the tracking systems. The primary objective of the Biosatellite II mission was to determine if organisms were more, or less, sensitive to ionizing radiation in microgravity than on Earth. To study this question, an artificial source of radiation was supplied to a group of experiments mounted in the forward part of the spacecraft.

  • OGO 6 - . Payload: OGO F. Mass: 634 kg (1,397 lb). Nation: USA. Agency: NASA Greenbelt. Class: Earth. Type: Magnetosphere satellite. Spacecraft: OGO. Decay Date: 1979-10-12 . USAF Sat Cat: 3986 . COSPAR: 1969-051A. Apogee: 1,089 km (676 mi). Perigee: 397 km (246 mi). Inclination: 82.0000 deg. Period: 99.70 min. OGO 6 was a large observatory instrumented with 26 experiments designed to study the various interrelationships between, and latitudinal distributions of, high-altitude atmospheric parameters during a period of increased solar activity. On June 22, 1969, the spacecraft potential dropped significantly during sunlight operation and remained so during subsequent sunlight operation. This unexplained shift affected seven experiments which made measurements dependent upon knowledge of the spacecraft plasma sheath. During October 1969, a string of solar cells failed, but the only effect of the decreased power was to cause two experiments to change their mode of operation. Also during October 1969, a combination of manual and automatic attitude control was initiated, which extended the control gas lifetime of the attitude control system. In August 1970, tape recorder (TR) no. 1 operation degraded, so all recorded data were subsequently taken with TR no. 2. By September 1970, power and equipment degradation left 14 experiments operating normally, 3 partially, and 9 off. From October 14, 1970, TR no. 2 was used only on Wednesdays (world days) to conserve power and extend TR operation. In June 1971, the number of 'on' experiments decreased from 13 to 7, and on June 28, 1971, the spacecraft was placed in a spin-stabilized mode about the yaw (Z) axis and turned off due to difficulties with spacecraft power. OGO 6 was turned on again from October 10, 1971, through March 1972, for operation of experiment 25 by The Radio Research Laboratory, Japan.

The intent had been to fly a 6 kg male pig-tailed monkey (Macaca nemestrina) named Bonnie in Earth-orbit for 30 days. However, after only 8.8 days in orbit, the mission was terminated because of the subject's deteriorating health. High development costs were a strong incentive for maximising the scientific return from the mission. Because of this, the scientific goals had become exceedingly ambitious over time, and a great many measurements were conducted on the single research subject flown. Although the mission was highly successful from a technical standpoint, the science results were apparently compromised. Additional Details: here....

Apogee: 1,046 km (649 mi). Perigee: 1,039 km (645 mi). Inclination: 99.2000 deg. Period: 106.00 min. Space Electric Rocket Test; the ion engines aboard were operated until 1981. The SERT 2 development program started in 1966 and included thruster ground tests of 6742 hours and 5169 hours duration. A prototype version of the SERT 2 spacecraft was ground-tested for a period of 2400 hours with an operating ion engine. In addition to diagnostic equipment and related ion engine hardware, the spacecraft had two identical 15 cm diameter, mercury ion engines. Flight objectives included in-space operation for a period of 6 months, measurement of thrust, and demonstration of electromagnetic compatibility. The thruster maximum power level was 0.85 kW, and this provided operation at a 28 mN thrust level at 4200 s specific impulse. Flight data were obtained from 1970 to 1981 with an ion engine operating intermittently in one of three different modes, namely, HV ion extraction, discharge chamber operation only, or just neutralizer operation. Major results were that two mercury engines thrusted for periods of 3781 hours and 2011 hours. Test duration was limited due to shorts in the ion optical system. Thrust measured in space and on the ground agreed within the measurement uncertainties. Up to 300 thruster restarts were demonstrated. One power-processing unit accumulated nearly 17,900 hours during the course of the mission. Additionally, the ion propulsion system was electromagnetically compatible with all other spacecraft systems.

Decay Date: 1971-02-17 . COSPAR: F710217A. KH-4B. The launch vehicle had a very cold boattail due to a hose discovered to be leaking away warming air to the boattail. The boattail was colder than usual, below freezing. Based on earlier tests of the Thor for just that condition, as relayed by Ed Dierdorf, Thor chief engineer at the time, the temp low was of no concern.

    The only problem was that those tests were made with a Thor that carried a Rocketdyne engine lubricated with "lube oil". The Thor being launched used a fuel additive, "Orinite" (like STP "super snot"). The technician that pumped the Orinite into its cannister later stated, "It wasn't for lack of orinite. I put it in just like the procedure said, and I could feel when it was full (with the hand pump). To make sure, I gave it another slug."

    That "other slug" cracked the output valve that was only supposed to be cracked by turbopump output pressure. When it cracked the output valve a bit of the "honey" squirted down the tube toward engine bearing jets. This line had a low spot in it by design. The Orinite settled there. When it was chilled by the low temp air at lox loading, the Orinite formed a plug.

    Unaware of this chain of circumstances, Launch Director Philip Payne made the decision to launch. The rocket (carrying Agena D and payload) flew for 18 seconds, then wiped out its gears, causing the turbine to overspeed and shed its vanes. These punctured various parts in the boattail like machine gun bullets. With loss of power, the rocket fell not far from the launch pad into Bear Creek canyon.

    The final cause was therefore found to be loss of engine lubrication at startup.

Apogee: 5,947 km (3,695 mi). Perigee: 5,839 km (3,628 mi). Inclination: 109.9000 deg. Period: 225.50 min. LAGEOS (Laser Geodetic Satellite) was a very dense (high mass-to-area ratio) laser retroreflector satellite which provided a permanent reference point in a very stable orbit for such precision earth-dynamics measurements as crustal motions, regional strains, fault motions, polar motion and earth-rotation variations, solid earth tides, and other kinematic and dynamic parameters associated with earthquake assessment and alleviation. The performance in orbit of LAGEOS was limited only by degradation of the retroreflectors, so many decades of useful life can be expected. The high mass-to-area ratio and the precise, stable (attitude-independent) geometry of the spacecraft, together with the orbit, made this satellite the most precise position reference available. Because it is visible in all parts of the world and has an extended operation life in orbit, LAGEOS can serve as a fundamental standard for decades. Additional Details: here....

  • ISEE 3 - . Payload: ISEE C. Mass: 479 kg (1,056 lb). Nation: USA. Agency: NASA Greenbelt. Class: Earth. Type: Magnetosphere satellite. Spacecraft: ISEE. USAF Sat Cat: 11004 . COSPAR: 1978-079A. Apogee: 1,089,200 km (676,700 mi). Perigee: 181 km (112 mi). Inclination: 1.0000 deg. Period: 67,852.90 min. International Sun-Earth Explorer; later renamed the International Cometary Explorer. Measured interaction between solar wind and Earth; rendezvoused with comet Giacobini-Zinner September 11, 1985. After several passes through the Earth's magnetotail, with gravity assists from lunar flybys in March, April, September and October of 1983, a final close lunar flyby (119.4 km above the moon's surface) on December 22, 1983, ejected the spacecraft out of the Earth-Moon system and into a heliocentric orbit ahead of the Earth, on a trajectory intercepting that of Comet Giacobini-Zinner. A total of fifteen propulsive maneuvers (four of which were planned) and five lunar flybys were needed to carry out the transfer from the halo orbit to an escape trajectory from the earth-moon system into a heliocentric orbit. The primary scientific objective of ICE was to study the interaction between the solar wind and a cometary atmosphere. As planned, the spacecraft traversed the plasma tail of Comet Giacobini-Zinner on September 11, 1985, and made in situ measurements of particles, fields, and waves. It also transited between the Sun and Comet Halley in late March 1986, when other spacecraft (Giotto, Planet-A, MS-T5, VEGA) were also in the vicinity of Comet Halley on their comet rendezvous missions. ICE became the first spacecraft to directly investigate two comets. An update to the ICE mission was approved by NASA headquarters in 1991. It defined a Heliospheric mission for ICE consisting of investigations of coronal mass ejections in coordination with ground-based observations, continued cosmic ray studies, and special period observations such as when ICE and Ulysses are on the same solar radial line. As of January 1990, ICE was in a 355 day heliocentric orbit with an aphelion of 1.03 AU, a perihelion of 0.93 AU and an inclination of 0.1 degree. This will bring it back to the vicinity of the earth-moon system in August, 2014. Termination of operations of ISEE 3 was authorized May 5, 1997. Additional Details: here....

Spacecraft charging experiments. The SCATHA spacecraft had two charged particle injection systems, one of which was the Satellite Positive-Ion-Beam System (SPIBS). This was a xenon ion source which included some of the technologies used in thrusters: however, the discharge chamber was not performance optimized as was done with ion engines. Maximum operating power was 0.045 kW, and the ion source could produce a thrust of about 0.14 mN at a specific impulse of 350 s. Ions could be ejected at 1 keV or 2 keV. Neutralization was accomplished by a tantalum filament. The specific impulse was low because there was no attempt to optimize the propellant efficiency. The SPIBS system was ground-tested for a period of 600 hours. The SCATHA spacecraft was placed in a near geosynchronous orbit. Ion beam operations were performed intermittently over a 247 day period. The SCATHA flight demonstrated that a charged spacecraft, and the dielectric surfaces on it, could be safely discharged by emitting a very low energy (<50 eV) neutral plasma -- in effect shorting the spacecraft to the ambient plasma before dangerous charging levels could be reached.

RME validated stabilization, tracking, and pointing technologies for Strategic Defense Initiative (SDI) missions through a credible demonstration of a space-based relay mirror system. The Wideband Angular Vibration Experiment (WAVE) measured low-level angular vibrations affecting performance of acquisition, tracking, and pointing systems. The experiment demonstrated that a laser beam can be accurately relayed from the earth to an orbiting satellite 450 kilometers away and then back to a 3-meter target on the ground. It achieved relay beam pointing accuracy which was 16 times better than the technical requirement. WAVE demonstrated the capability to discern platform disturbance amplitudes of a few nanoradians at discrete frequencies and is therefore a candidate to fulfill similar requirements for future ATP experiments.

The Delta's second stage demonstrated its restart capability in 4 burns: Burn 1 placed the rocket and payload into a low circular orbit; Burn 2 raised the apogee to 1400 km; Burn 3 circularised the orbit at 1400 km. The second stage then separated, and Burn 4 lowered the spent stage's perigee to a low altitude to ensure the stage would decay quickly and not add to the space junk already on orbit. Stage 3 burned once to place the payload and its kick motor into a high 1400 km perigee geosynchronous transfer orbit. The Stage 4 Star 30 apogee kick motor circularised the spacecraft's orbit at geostationary altitude. Geostationary at 0.8 degrees W. Positioned in geosynchronous orbit at 1 deg W in 1998-1999 As of 4 September 2001 located at 0.83 deg W drifting at 0.000 deg E per day.

  • Galaxy 10 - . Mass: 3,876 kg (8,545 lb). Nation: USA. Agency: PanAmSat. Manufacturer: El Segundo. Program: Galaxy. Class: Communications. Type: Civilian communications satellite. Spacecraft: HS 601. COSPAR: F980827A. Built by Hughes/El Segundo for Panamsat. The satellite carried 24 C-band and 24 Ku-band transponders to provide US/Caribbean coverage, and was to have replaced the ageing SBS-5 satellite at 123 deg West. Replenishing the Galaxy/PAS constellation was a high priority for Panamsat following the loss of Galaxy 4 and problems with Galaxy 7. Galaxy 11 was not scheduled to go up until the first launch of the Sea Launch Zenit-3SL in early 1999, and this booster was in limbo due to legal problems with unauthorised transfer of technical data from Boeing to Russia. In addition there were several PAS satellites awaiting launch over the next year on Proton and Ariane vehicles.

The primary mission of Deep Space 1 probe was to test new technology for future interplanetary spacecraft, the main experiment being an ion propulsion engine using xenon propellant. It had an initial mass of 486.3 kg, including 81.5 kg of Xenon and 31.1 kg of hydrazine propellants. The Delta 7326 used three Alliant GEM-40 solid strap-on motors, the standard Delta II core vehicle, and a Thiokol Star 37FM solid motor as the third stage. The Delta second stage entered a 185 km parking orbit, then fired again to enter a 174 km x 2744 km x 28.5 degree orbit. The Star 37FM then separated and accelerated to place Deep Space 1 to escape velocity. Deep Space 1 successfully started its ion engine on November 24 after an initial attempt failed after four minutes on November 10. From its initial solar orbit of 0.99 AU x 1.32 AU x 0.4 degree, Deep Space 1 was to fly past the 3 km diameter asteroid 1992 KD at its perihelion of 1.33 AU. The spacecraft then flew past the nucleus of comet 19P/Borrelly at a distance of 2200 km at 2230 GMT on Sep 22 2001. It survived the encounter in good shape, sending back photos of the comet. At the encounter DS1 was in a 1.3 x 1.5 AU x 0 deg (ecliptic) solar orbit; Borrelly's orbit was 1.3 x 5.9 AU.

  • Mars Climate Orbiter - . Mass: 629 kg (1,386 lb). Nation: USA. Agency: JPL. Manufacturer: Martin. Program: Mars Surveyor. Class: Mars. Type: Mars probe. Spacecraft: MCO. Decay Date: 1999-09-23 . USAF Sat Cat: 25571 . COSPAR: 1998-073A. The Mars Climate Orbiter was the second flight of the Mars Surveyor Program. The probe was to enter a 160 km x 38600 km polar orbit around Mars on September 23,1999, and use aerobraking to reach a 373 km x 437 km x 92.9 degree sun-synchronous mapping orbit by November 23 1999. While the Mars Orbit Insertion burn began as planned on September 23, 1999 at 08:50 GMT, no signal was received after the spacecraft went behind the planet. Subsequent investigation showed that the spacecraft had plunged deep into the Martian atmosphere, with its closest approach to Mars being 57 km. It was concluded that the spacecraft burnt up in the atmosphere. It was later found that cutbacks in tracking, combined with incorrect values in a look-up table imbedded deep in the spacecraft software (use of pounds force instead of newtons) were to blame. This failure led to a shake-up of NASA's 'faster, better, cheaper' approach to unmanned spaceflight. Additional Details: here....

  • Mars Polar Lander - . Mass: 576 kg (1,269 lb). Nation: USA. Agency: JPL. Manufacturer: Martin. Class: Mars. Type: Mars probe. Spacecraft: Mars Polar Lander. Decay Date: 1999-12-03 . USAF Sat Cat: 25605 . COSPAR: 1999-001A. The Mars Polar Lander was placed by the first burn of the second stage into a 157 x 245 km x 28.35 deg parking orbit. The second stage restarted at 20:55 GMT and shut down in a 226 x 740 km x 25.8 deg Earth orbit. The solid rocket third stage (a Star 48B with a Nutation Control System and a yo-yo despin device) then ignited and put the spacecraft into solar orbit, separating at 21:02 GMT. Mars Polar Lander was to land near the south pole of Mars on December 3, 1999, and conduct conduct a three month mission, trenching near its landing site and testing for the presense of frozen water and carbon dioxide. Attached were two Deep Space 2 Microprobes, penetrators which would impact the Martian surface separately from the lander and return data on subsurface conditions from widely spaced points.

    When the spacecraft reached Mars on December 3, the lander separated from the cruise stage at 19:51 UTC and the two penetrators, Scott and Amundsen, were to separate about 20 seconds later. No further communications were ever received from the spacecraft. Landing had been expected at 20:01 UTC at 76.1S 195.3W, with the penetrators landing a few kilometres from each other at 75.0S 196.5W.

    This failure resulted in a review and reassessment of NASA's 'faster, better, cheaper' approach to planetary missions.
