Susan J. Helms - Spaceflight Experience

Spaceflight Experience

Selected by NASA in January 1990, Helms became an astronaut in July 1991. She flew on STS-54 (1993), STS-64 (1994), STS-78 (1996), STS-101 (2000) and served aboard the International Space Station as a member of the ISS Expedition 2 crew (2001). A veteran of five space flights, Helms logged 5,064 hours in space, including an EVA of 8 hours and 56 minutes (world record).

STS-54 Endeavour, January 13–19, 1993. The primary objective of this mission was the deployment of a $200-million NASA Tracking and Data Relay Satellite (TDRS-F). A Diffuse X-Ray Spectrometer (DXS) carried in the payload bay, collected over 80,000 seconds of quality X-ray data that will enable investigators to answer questions about the origin of the Milky Way galaxy. The crew demonstrated the physics principles of everyday toys to an interactive audience of elementary school students across the United States. A highly successful extra-vehicular activity (EVA) resulted in many lessons learned that will benefit International Space Station assembly. Mission duration was 5 days, 23 hours, 38 minutes, 17 seconds.

STS-64 Discovery, September 9–20, 1994. On this flight, Helms served as the flight engineer for orbiter operations and the primary RMS operator aboard Space Shuttle. The major objective of this flight was to validate the design and operating characteristics of Lidar in Space Technology Experiment (LITE) by gathering data about the Earth's troposphere and stratosphere. Additional objectives included the deploy and retrieval of SPARTAN-201, a free-flying satellite that investigated the physics of the solar corona, and the testing of a new EVA maneuvering device. The Shuttle Plume Impingement Flight Experiment (SPIFEX) was used to collect extensive data on the effects of jet thruster impingement, in preparation for proximity tasks such as space station docking. Mission duration was 10 days, 22 hours, 51 minutes.

STS-78 Columbia, June 20 to July 7, 1996, Helms was the payload commander and flight engineer aboard Columbia, on the longest Space Shuttle mission to date (later that year the STS-80 mission broke its record by nineteen hours.) The mission included studies sponsored by ten nations and five space agencies, and was the first mission to combine both a full microgravity studies agenda and a comprehensive life science investigation. The Life and Microgravity Spacelab mission served as a model for future studies on board the International Space Station. Mission duration was 16 days, 21 hours, 48 minutes.

STS-101 Atlantis, May 19–29, 2000, was a mission dedicated to the delivery and repair of critical hardware for the International Space Station. Helms prime responsibilities during this mission were to perform critical repairs to extend the life of the Functional Cargo Block (FGB). In addition, she had prime responsibility of the onboard computer network and served as the mission specialist for rendezvous with the ISS. Mission duration was 9 days, 20 hours and 9 minutes.

Expedition 2 March 8 to August 22, 2001 was a mission to the International Space Station and Helms was as a member of the second crew to inhabit the International Space Station Alpha. The Expedition 2 crew (two American astronauts and one Russian cosmonaut) launched on March 8, 2001 on board STS-102 Discovery and successfully docked with the station on March 9, 2001. The Expedition 2 crew installed and conducted tests on the Canadian made Space Station Robotic arm (SSRMS), conducted internal and external maintenance tasks (Russian and American), in addition to medical and science experiments. During her stay on board the Space Station, Helms installed the Airlock (brought up on the STS-104 mission) using the SSRM. She and her crewmates also performed a 'fly around' of the Russian Soyuz spacecraft and welcomed the visiting Soyuz crew that included the first space tourist, Dennis Tito. On March 11 she performed a world record 8 hour and 56 minute space walk to install hardware to the external body of the laboratory module. Helms spent a total of 163 days aboard the Space Station. She returned to earth with the STS-105 crew aboard Discovery on August 22, 2001.
