STS-26 Fact Sheet

Written and Edited by Cliff Lethbridge

 

STS-26 -- Discovery

 

26th Space Shuttle Mission

7th Flight of Discovery

 

Crew:

 

Frederick H. Hauck, Commander

Richard O. Covey, Pilot

John M. Lounge, Mission Specialist

David C. Hilmers, Mission Specialist

George D. Nelson, Mission Specialist

 

Orbiter Preparations:

 

Tow to Orbiter Processing Facility - October 30, 1986

Rollover to Vehicle Assembly Building - June 21, 1988

Rollout to Launch Pad 39B - July 4, 1988

 

Launch:

 

September 29, 1988 -- 11:37:00 a.m. EDT. Launch was delayed 1 hour, 38 minutes to replace fuses in the cooling system of two of the crew's flight pressure suits, and due to higher than expected upper atmosphere winds. Suit repairs were successful and wind constraints were waived as not being a sufficient deterrent to a nominal flight.

 

Landing:

 

October 3, 1988 - 9:37:11 a.m. PDT at Runway 17, Edwards Air Force Base, California. Rollout distance was 7,451 feet. Rollout time was 49 seconds. Mission duration was 4 days, 1 hour, 0 minutes, 11 seconds. Landing occurred during the 64th orbit.

 

Mission Summary:

 

NASA's Tracking and Data Relay Satellite-3 (TDRS-3) was deployed using an Inertial Upper Stage (IUS) boost to geosynchronous orbit.

 

Secondary payloads included the Physical Vapor Transport of Organic Solids (PVTOS), Protein Crystal Growth (PCG), Infrared Communications Flight Experiment (IRCFE), Aggregation of Blood Cells (ARC), Isoelectric Focusing Experiment (IFE), Mesoscale Lightning Experiment (MLE) and Phase Partitioning Experiment (PPE).

 

Also flown were the Earth-Limb Radiance Experiment (ELRAD), Automated Directional Solidification Furnace (ADSF), two SSIP experiments and Orbiter Experiments Autonomous Supporting Instrumentation System-1 (OASIS-1), which recorded a variety of environmental measurements during various phases of the flight.

 

The Shuttle's Ku-band antenna in the payload bay was deployed but did not function due to failure of dish antenna command and actual telemetry. During the mission, Discovery's cabin Flash Evaporator System iced up, causing cabin temperatures to rise to the mid-80's for much of the flight.
