While in medical school, Dr. Parazynski competed on the United States Development Luge Team and was ranked among the top 10 competitors in the nation during the 1988 Olympic Trials. He also served as an Olympic Team Coach for the Philippines during the 1988 Olympic Winter Games in Calgary, Canada, and later, as Honorary Captain of the United States Olympic Luge Team during the 2010 Olympic Winter Games in Vancouver, Canada.
EXPERIENCE: While an undergraduate at Stanford University, Dr. Parazynski studied antigenic variation in African Sleeping Sickness, using sophisticated molecular biological techniques. While in medical school, he was awarded a NASA Graduate Student Fellowship and conducted research at NASA-Ames Research Center on fluid shifts that occur during human spaceflight. Additionally, he has been involved in the design of several exercise devices that are being developed for long-duration spaceflight, and he has conducted research on high-altitude acclimatization. Dr. Parazynski has numerous publications in the field of space physiology and has a particular expertise in human adaptation to stressful environments. He has also invented a number of medical devices and other technologies for life in extreme environments.
NASA EXPERIENCE: Selected as an astronaut in March 1992, Dr. Parazynski reported to the Johnson Space Center in August 1992. He completed one year of training and evaluation and was qualified as a mission specialist. Dr. Parazynski initially served as one of the crew representatives for Extravehicular Activity (EVA) in the Astronaut Office Mission Development Branch. Following his first flight, he was assigned as a backup for the third American long-duration stay aboard Russia’s Space Station Mir and was expected to serve as a prime crew member on a subsequent mission. He spent five months in training at the Gagarin Cosmonaut Training Center, Star City, Russia. In October 1995, when sitting-height parameters raised concerns about his fitting safely in the Soyuz vehicle in the event of an emergency aboard the Mir station, he was deemed too tall for the mission and was withdrawn from Mir training. He has served as the Astronaut Office crew representative for space shuttle, space station and Soyuz training, as Deputy (Operations and Training) of the Astronaut Office ISS Branch, and as Chief of the Astronaut Office EVA Branch. In the aftermath of the Columbia tragedy, he was the Astronaut Office lead for space shuttle thermal protection system inspection and repair. A veteran of five spaceflights, STS-66 (1994), STS-86 (1997), STS-95 (1998), STS-100 (2001) and STS-120 (2007), Dr. Parazynski has logged more than 1,381 hours (over eight weeks) in space, including more than 47 hours during seven spacewalks, and has traveled more than 23 million miles. Dr. Parazynski retired from NASA in March 2009 to work in private industry and to pursue other entrepreneurial and exploration interests.
SPACEFLIGHT EXPERIENCE: The STS-66 Atmospheric Laboratory for Applications and Science-3 (ATLAS-3) mission launched from Kennedy Space Center, Florida, on November 3, 1994, and returned to land at Edwards Air Force Base, California, on November 14, 1994. ATLAS-3 was part of an on-going program to determine the Earth’s energy balance and atmospheric change over an 11-year solar cycle, particularly with respect to humanity’s impact on global-ozone distribution. Dr. Parazynski had responsibility for a number of in-orbit activities, including the operation of the ATLAS experiments and Spacelab Pallet, as well as several secondary experiments in the crew cabin. The crew also successfully evaluated the Interlimb Resistance Device, a free-floating exercise he co-invented to prevent musculoskeletal atrophy in microgravity. Space shuttle Atlantis circled the earth 175 times and traveled more than 4.5 million miles during its 262-hour and 34-minute flight.
STS-86 Atlantis (September 25 to October 6, 1997) was the seventh mission to rendezvous and dock with the Russian Space Station Mir. Highlights of the mission included the exchange of U.S. crew members Mike Foale and David Wolf, the transfer of 10,400 pounds of science and logistics and the first shuttle-based joint American-Russian spacewalk. Dr. Parazynski served as the flight engineer (MS2) during the flight and was also the navigator during the Mir rendezvous. Dr. Parazynski (EV1) and Russian cosmonaut Vladimir Titov performed a five-hour and one-minute spacewalk, during which they retrieved four experiment packages that were first deployed during the STS-76 shuttle-Mir docking mission. They also deployed the Spektr Solar Array Cap, which was designed to be used in a future Mir spacewalk to seal a leak in the Spektr module’s damaged hull. Other objectives of spacewalk included the evaluation of common spacewalk tools to be used by astronauts wearing either Russian- or American-made spacesuits, and a systems flight test of the Simplified Aid for EVA Rescue (SAFER). Space shuttle Atlantis circled the earth 169 times and traveled more than 4.2 million miles during its 259-hour and 21-minute flight.
STS-95 Discovery (October 29 to November 7, 1998) was a nine-day mission, during which the crew supported a variety of research payloads, including the deployment of the Spartan solar-observing spacecraft and the testing of the Hubble Space Telescope Orbital Systems Test Platform. The crew also conducted investigations on the correlation between spaceflight and the aging process. Dr. Parazynski was the flight engineer (MS2) for the mission as well as the navigator for the Spartan spacecraft rendezvous. During the flight, he also operated the shuttle’s robotic arm in support of the testing of several space-vision systems being considered for station assembly. In addition, he was responsible for monitoring several life sciences investigations, including those involving crewmate Senator John Glenn. The mission was accomplished in 134 Earth orbits, traveling 3.6 million miles in 213 hours and 44 minutes.
STS-100 Endeavour (April 19 to May 1, 2001) was the ninth mission to the International Space Station, during which the crew successfully delivered and installed the space station “Canadarm2” robotic arm, to be used for all future space station assembly and maintenance tasks. Dr. Parazynski conducted two spacewalks with Canadian colleague, Chris Hadfield, to assemble and power the next-generation robotic arm. Additionally, the pair installed a new UHF radio antenna for space€‘to€‘space communications during space shuttle rendezvous and station spacewalk activity. A critical in-orbit spare, a direct current switching unit, was also transferred to the space station during the 14-hour and 50-minute spacewalk. Also during the flight, Dr. Parazynski operated Endeavour's robotic arm to install, and later remove, the Italian-built “Raffaello” Multi-Purpose Logistics Module. Traveling 4.9 million miles in 283 hours and 30 minutes, the mission was accomplished in 186 Earth orbits.
STS-120 Discovery (October 23 to November 7, 2007) launched from and returned to land at Kennedy Space Center. During the mission, the Node 2 module named “Harmony” was delivered to the International Space Station. This element opened up the capability for future international laboratories to be added to the station. Dr. Parazynski served as EV1 (lead spacewalker) and accumulated more than 27 hours in four spacewalks. One of the major spacewalk mission objectives was the relocation of the P6 solar array from the top of the Z1 truss to the end of the port side of the integrated truss structure. During the IVA-commanded redeploy of the solar array, several array panels snagged and were damaged, requiring an unplanned spacewalk to successfully repair the array. The mission was accomplished in 238 orbits, traveling 6.2 million miles in 15 days, two hours, and 23 minutes.

Atlantis was launched on a mission to the Russian Mir space station. The TI rendevous terminal initiation burn was carried out at 17:32 GMT on September 27, and Atlantis docked with the SO (Docking Module) on the Mir complex at 19:58 GMT. The crew exchange was completed on September 28, with David Wolf replacing Michael Foale on the Mir crew. On October 1 cosmonaut Titov and astronaut Parazynski conducted a spacewalk from the Shuttle payload bay while Atlantis was docked to Mir. They retrieved four MEEP (Mir Environmental Effects Payload ) exposure packages from Mir's SO module and installed the Spektr solar array cap. The MEEP experiments had been attached to the Docking Module by astronauts Linda Godwin and Rich Clifford during Shuttle mission STS-76 in March 1996. In addition to retrieving the MEEP, Parazynski and Titov were to continue an evaluation of the Simplified Aid For EVA Rescue (SAFER), a small jet-backpack designed for use as a type of life jacket during station assembly.
Atlantis undocked from Mir at 17:28 GMT on October 3 and conducted a flyaround focused on the damaged Spektr Module to determine the location of the puncture in its hull. The Mir crew pumped air into the Spektr Module using a pressure regulator valve, and the Shuttle crew observed evidence that, as expected, the leak seemed to be located at the base of the damaged solar panel. Final separation of Atlantis from Mir took place around 20:28 GMT. After two landing attempts were waved off on October 5 due to heavy cloud cover, the crew fired the engines to deorbit at 20:47 GMT on October 6 and landed at Kennedy Space Center at 21:55.
The Shuttle Discovery blasted off into a cloudless sky today at 1:19 p.m. Central time from the Kennedy Space Center to kick off a planned nine-day scientific research mission and to return John Glenn to space, 36 years, 8 months and nine days after he became the first American to orbit the Earth.

The flight of STS-95 provoked more publicity for NASA than any other flight in years, due to the presence of ex-astronaut Senator John Glenn on the crew, which also included the first Spanish astronaut, Pedro Duque. The US Navy PANSAT student satellite was deployed on Oct 30 into a 550 km x 561 x 28.5 degree orbit. The Spartan 201 satellite was deployed from Discovery on November 1 and retrieved on November 3. Spartan 201 was on its fifth mission to observe the solar corona. The data on this mission would be used to recalibrate the SOHO satellite which recently resumed observation of the Sun following loss of control. Discovery landed at 17:03:31 GMT November 7 on Runway 33 at the Shuttle Landing Facility at Kennedy Space Center.
Discovery's astronauts were awakened at 6 a.m. Central time this morning by Andy Williams' rendition of the 1962 Academy Award winning song, "Moon River." Annie Glenn requested the song as a tribute to the longstanding friendship between Williams and her husband, Payload Specialist John Glenn.

Space Shuttle OV-105 Endeavour was launched on mission STS-100 to carry out International Space Station Flight 6A continued the outfitting of the Station. The crew of four Americans, one Russian, one Canadian and one Italian were to install an 18 meter, 1,700 kg Canadian robotic arm named Canadarm-2 on the ISS, and to transport an Italian cargo container, Raffaello, which delivered 4,500 kg of supplies and equipment to the station. Total payload of 13,744 kg consisted of:
On 23 April the SSRMS station manipulator was unberthed from the SLP Spacelab pallet at 1114 GMT and latched on to the PDGF fixture on the Destiny ISS module at 1416 GMT. This was followed at 1458 GMT with the MPLM-2 Raffaello module being moved from Endeavour's payload bay by the Shuttle's RMS and berthed to the nadir port on the ISS Unity module at 1600 GMT. Over the next few days, the cargo racks on the MPLM were transferred to Destiny. Raffaello was then unberthed from Unity at 2003 GMT on April 27 and reberthed in the rear of Endeavour's bay for return to earth at 2059 GMT.
Undocking of Endeavour was delayed by a series of computer problems at the Station. Failures in the Station's command and control computers left only one of the three computers operating.
They were all restarted by April 29, and the Shuttle RMS grappled the Spacelab pallet at 2044 GMT . The station's Canadarm-2 released it at 2106 GMT, and the RMS berthed the pallet back in the Shuttle cargo bay. Endeavour undocked from the Station at 1734 GMT on April 29. The weather in Florida was bad at the planned May 1 landing time, so Endeavour landed in California. The deorbit burn was at 1502 GMT on May 1, with landing at 1610:42 GMT on runway 22 at Edwards. Endeavour returned to the Kennedy Space Center atop a Boeing 747 SCA aircraft on May 9.

Main mission objectives were delivery of the Harmony module to the station, and external work to move the P6 truss to its final location and put the ISS into its full-power configuration for the first time. Discovery docked with the ISS at the Destiny module at 12:40 GMT on 25 October. The cargo of 17,390 kg was as follows:
It proved to be a perfect day for a spacewalk. In just over six hours, STS-120 Mission Specialists Scott Parazynski and Doug Wheelock installed the Harmony module in its temporary location on the International Space Station, readied the P6 truss for its relocation on Sunday, retrieved a failed radio communications antenna and snapped shut a window cover on Harmony that opened during launch on the space shuttle. Additional Details: here....
The astronauts emerged from the Quest hatch at 10:01 GMT. They moved an antenna from the Z1 truss and stowed it in the payload bay, prepared the P6 truss for separation from Z1, and assisted in installation of the Harmony module, which was unberthed from the shuttle bay by the ISS Canadarm-2 and docked to the Unity module.
The astronauts emerged from the Quest hatch at 09:32 GMT. They assisted in unberthing of the P6 truss and its placement in a parked position. They also installed handrails and a grapple fixture on Harmony and inspected the malfunctioning Solar Array Rotary Joint (SARJ) on the S3/S4 truss.
Astronauts Scott Parazynski and Doug Wheelock today install the International Space Station's P6 truss in its final location. A new task was also added to this third spacewalk of the mission to provide comparison data of the station's two solar array rotary joints. The spacewalk is set to begin at 3:53 a.m. CDT. Additional Details: here....
The astronauts emerged from the Quest hatch at 08:44 GMT. They assisted in the mating of the P6 to P5 trusses and deployment of a radiator from P6. Wheelock transferred a spare Main Bus Switching Unit (MBSU) from the Shuttle bay to the External Stowage Platform 3 (ESP3). P6 solar array wing 2B was successfully redeployed; but deployment of array 4B had to be halted when a tear developed in the solar panel.
The astronauts emerged from the Quest hatch and rode the ISS Canadarm II 50 m out to the snagged P6 solar array. Parazynski cut a snagged wire and installed homemade stabilizers designed to strengthen the array's structure and stability in the vicinity of the damage. Wheelock helped from the truss by keeping an eye on the distance between Parazynski and the array. Afterwards they observed as ground controllers completed successful extension of the array.
All systems are go for this morning's undocking of space shuttle Discovery from the International Space Station, completing 11 days of joint docked operations that saw the successful delivery of a new pressurized module and the repair of a damaged solar array wing. Additional Details: here....
