Midstar


American technology satellite. One launch, 2007.03.09.

The aim of the UN Naval Academy's Midshipman Space Technology Applications Research (MidSTAR) Program was to develop a general-purpose satellite bus capable of supporting a variety of space missions by easily accommodating a wide range of space experiments and instruments.

The integration of the experiments with the satellite bus could be accomplished with minimal changes to the satellite bus design. MidSTAR was intended to be a relatively low-cost, quick response platform accommodating small payloads approved by the Department of Defense (DoD) Space Experiments Review Board (SERB) and launched through the DoD Space Test Program (STP).

MidSTAR satellites were of two types. MidSTAR mod 1 was designed for use on the Expendable Secondary Payload Adaptor (ESPA) Ring developed by Air Force Research Laboratory (AFRL) for placement on Delta IV or Atlas V expendable launch vehicles. MidSTAR mod 2 was to have been designed for deployment from the Space Shuttle via the Canister All Payload Ejection (CAPE) system developed by AFRL.

The baseline MidSTAR mission included a single spacecraft under the command and control of a single satellite ground station located at the Naval Academy in Annapolis, Maryland. The ground station forwarded downlinked data files to the Principal Investigators via the Internet. Secondary ground control was available through Naval Postgraduate School in Monterey California.

  • Atlas V The Atlas V launch vehicle system was a completely new design that succeeded the earlier Atlas series. Atlas V vehicles were based on the 3.8-m (12.5-ft) diameter Common Core Booster (CCB) powered by a single Russian RD-180 engine. These could be clustered together, and complemented by a Centaur upper stage, and up to five solid rocket boosters, to achieve a wide range of performance. More...

Associated Launch Sites
  • Cape Canaveral America's largest launch center, used for all manned launches. Today only six of the 40 launch complexes built here remain in use. Located at or near Cape Canaveral are the Kennedy Space Center on Merritt Island, used by NASA for Saturn V and Space Shuttle launches; Patrick AFB on Cape Canaveral itself, operated the US Department of Defense and handling most other launches; the commercial Spaceport Florida; the air-launched launch vehicle and missile Drop Zone off Mayport, Florida, located at 29.00 N 79.00 W, and an offshore submarine-launched ballistic missile launch area. All of these take advantage of the extensive down-range tracking facilities that once extended from the Cape, through the Caribbean, South Atlantic, and to South Africa and the Indian Ocean. More...
  • Cape Canaveral LC41 Titan, Atlas V launch complex. Complexes 40 and 41 were constructed as part of the Integrate-Transfer-Launch (ITL) Titan launch facility at the north end of Cape Canaveral in the early 1960s. Over the next three decades, the complexes supported a wide variety of military space missions involving Titan IIIC, Titan 34D and Titan IV. Complex 41 was deactivated at the end of 1977, then upgraded for the Titan IV program in the 1986-88 period. In October 1999, Complex 41 was demolished with high explosives in order for a new pad for launch of the Atlas 5 rocket to be erected. By then it had been the starting point for 27 Titan flights.
