- The primary objective of the STS-72 mission is to capture and return
to Earth a Japanese microgravity research spacecraft known as
Space Flyer Unit (SFU). The 7,885lbs SFU spacecraft was launched by Japan's
National Space Development Agency (NASDA) from Tanegashima Space Center in
Japan at 8:01 UT on March 18, 1995 aboard a Japanese H-II rocket (HII-3).
- The STS-72 mission will also deploy (for about 50 hours) and then retrieve
the Office of Aeronautics and Space Technology Flyer (OAST-Flyer) spacecraft.
OAST-Flyer is the seventh in a series of missions aboard reuseable
free-flying Spartan carriers. It consists of four experiments:
Return Flux Experiment (REFLEX),
Global Positioning System Attitude Determination and Control Experiment
(GADACS), Solar Exposure to Laser Ordnance Device (SELODE) and the
University of Maryland Spartan Packet Radio Experiment (SPRE).
- Other experiments onboard STS-72 include the Shuttle Solar Backscatter
Ultraviolet Experiment (SSBUV-8) (previously flown on STS-34, STS-41, STS-43,
- STS-45, STS-56, STS-62 and STS-66), EDFT-03, Shuttle Laser Altimeter Payload
(SLA-01/GAS(5)), VDA-2, National Institutes of Health NIH-R3 Experiment,
Space Tissue Loss Experiment (STL/NIH-C), Pool Boiling Experiment (PBE)
(hardware previously flown on STS-47, STS-57 and STS-60) and the
Thermal Energy Storage (TES-2) experiment (previously flown on STS-69).
- Get Away Special payloads include the United States Air Force
Academy G-342 Flexible Beam Experiment (FLEXBEAM-2), Society of
Japanese Aerospace Companies' G-459 - Protein Crystal Growth
Experiment and the Jet Propulsion Laboratory GAS Ballast Can with
Sample Return Experiment.
- Endeavour's 10th flight also includes two 6.5 hour spacewalks by
three astronauts to test hardware and tools that will be used in the
assembly of the International Space Station starting in late 1997.
EVA-1 on flight day five consists of Crewmembers Leroy Chiao (EV1) and
Dan Barry (EV2) while EVA-2 on Flight Day 7 consists of Leroy Chiao
(EV1) and Winston Scott (EV2).
- Launch January 11, 1996 at 4:41:00.072 EST (23 min into the beginning of
the window). Launch window was 49 min 30sec and extended until 5:07:30 a.m.
EST. The exact length of the window was calculated based on the location of
the Japanese Space Flyer Unit prior to launch. (Reference KSC Press Release 1-96). Transoceanic Abort Site (TAL) was at Ben Guerir, Morocco.
- The countdown started on time at 7:30 am in Firing Room 1 of the
Launch Control Complex (LCC) at the T-43 hour mark. The astronaut
crew landed at the Shuttle Landing Facility at 9:30am on 1/8/96
(Reference KSC Shuttle Status 1/08/1996). The countdown included 25 hours
and 48 minutes of built-in holds. (Reference KSC Press Release 2-96).
The countdown went smoothly with only a few minor facility or
Ground Servicing Equipment (GSE) problems. Noise was noted on a UPS fan
and oil bearing temperature on LOX Pump 126 ran slightly higher than
expected. No corrective action was necessary. Just before the hold at
the T-20 minute mark, the Space Shuttle Main Engines (SSME) were running a
little cool so GN2 flow was adjusted. There were also some communications
problems that caused minor launch delays, one with MILA and one with
the new JSC front end processor. MILA switched to a backup system and
JSC switched to the old front end processor system.

- KSC, Saturday, January 20, 1996 2:41:41 A.M. EST Runway 15 (southwest
to northeast). Sonic Booms heard at KSC at 2:39 A.M. EST while
Endeavour was at 26,000ft. At 16,000 ft, Endeavour was 8nm from
the Shuttle Landing Facility and traveling at 400 miles per hour.
At 2:41 A.M. EST, Endeavour was at 9,000ft and 5 nm. Preflare was
done at 700ft altitude. Unofficial Main Gear touchdown at 2:41:41 AM
EST, (MET 8 days, 22 hrs, 00 min, 41 sec). Nose wheel touchdown at
2:41:54 AM EST (MET 8 days 22 hrs 00 min 54sec) and wheels stop
at 2:42:47 (MET 8 days 22 hrs 01min 47 sec). KSC Weather conditions
at the time of landing were acceptable (Reference KSC Weather History 01/20/1996 0200).
- Two landing opportunities were available for Saturday at the Kennedy
Space Center for Endeavour's homecoming. The first opportunity was used
which called for a firing of Endeavour's braking rockets at 12:41 a.m.
Saturday and a touchdown on Runway 33 at the Shuttle Landing Facility.
The second landing opportunity was not needed but would have been
about one hour and a half later with a landing at 4:17 a.m. EST.
