- Astro-2 is the second dedicated
Spacelab mission to conduct
astronomical observations in the ultraviolet spectral regions. It
consists of three unique instruments - the Hopkins Ultraviolet
Telescope (HUT), the Ultraviolet Imaging Telescope
(UIT) and the
Wisconsin Ultraviolet Photo-Polarimeter Experiment
experiments will select targets from a list of over 600 and observe
objects ranging from some inside the solar system to individual stars,
nebulae, supernova remnants, galaxies and active extragalactic
objects. This data will supplement data collected on the
mission flown on
in December 1990 aboard Columbia.
- Because most ultraviolet radiation is absorbed by
atmosphere, it cannot be studied from the ground. The far and extreme
ultraviolet region of the spectrum was largely unexplored before
Astro-1, but knowledge of all wavelengths is essential to obtain an
accurate picture of the universe.
Astro-2 will have almost twice the
duration of its predecessor, and a launch at a different time of year
allows the telescopes to view different portions of the sky. The
mission promises to fill in large gaps in astronomers' understanding
of the universe and lay the foundations for more discovery in the
- On the Middeck, science experiments include the Protein Crystal Growth
Thermal Enclosure System Vapor Diffusion Apparatus-03 experiment
(PCG-TES-03), the Protein Crystal Growth Single Thermal Enclosure
System-02 (PCG-STES-02), the Shuttle Amateur Radio Experiment-II
(SAREX-II), the Middeck Active Control Experiment
(MACE), the Commercial
Materials Dispersion Apparatus
Experiments-03 (CMIX-03) and the Midcourse Space Experiment
- The Middeck Active Control Experiment
(MACE) is a space engineering
research payload. It consists of a rate gyro, reaction wheels, a
precision pointing payload, and a scanning and pointing payload that
produces motion disturbances. The goal of the experiment is to test a
closed loop control system that will compensate for motion disturbances.
On orbit, Commander Stephen S. Oswald
and William G. Gregory will use
MACE to test about 200 different motion disturbance situations over 45
hours of testing during the mission. Information from MACE will be
used to design better control systems that compensate for motion in
- Two Get Away Special (GAS) payloads are also on board. They are
the G-387 and G-388 canisters. This experiment is sponsored by the
Australian Space Office and AUSPACE ltd. The objectives are to make
ultraviolet observations of deep space or nearby galaxies. These
observations will be made to study the structure of galactic
remnants, the distribution of hot gas in the Magellanic Clouds, the
hot galactic halo emission, and emission associated with galactic cooling
flows and jets. The two GAS canisters are interconnected with a cable.
Canister 1 has a motorized door assembly that exposes a UV telescope
to space when opened. UV reflective filters on the telescopes optics
determine its UV bandpass. Canister 2 contains two video recorders for
data storage and batteries to provide experiment power.
- Launch March 2, 1995. 1:38:34 am EST. Launch window was 2 hour 30 min.
- At 9:09pm EST, the only launch constraints were weather related with a
40% chance for launch. At 9:11pm the astronauts had their breakfast in the
astronaut quarters on the 3rd floor of the Operations and
Checkout building .
Commander Stephen S. Oswald and
William G. Gregory were given a final
weather briefing while the rest of the crew suited up. At 10:22pm,
STS-67 crew left for Pad 39-A and arrived at 10:42pm.
By 11:58pm the
crew was all loaded and
air-to-ground voice checks were
completed. By 12:50am on 3/2/95, the door to
Endeavour's mid-deck was
sealed and a go was given to clear the white room.
- There were 4 minor problems tracked during the count. The first
problem occured early in the count. An experimental configuration of
communications system caused a timing glitch that was quickly corrected.
This configuration enables the orbiter
to use the TDRSS during
in lew of the Bermuda Tracking station. The goal was to get a
communications lock via
TDRSS in 7 seconds instead of
a normal 40 seconds
and if successful, this will improved safety and may eventually
reduce the need for the Bermuda Tracking station. The second problem
was a minor leak in the LH2 storage system on Pad 39-A. This leak will
be investigated when crews visit the pad after launch. The third
minor problem occured when Endeavours Fuel Cells showed a degradation
in Fuel cell efficency. This was traced to a Helium contamination
during EDO pallet fill.
A purge of the line fixed the problem.
- At 1:26am a poll of the launch team
identified all teams but one
were go for launch. The final problem was an indication that the
B-supply secondary heater of the Flash
Evaporator System was
approaching a redline condition. This system is normally shutoff just
before launch. At 1:29am the primary
brought online and the
clock was picked up with a plan to count down to the T-5 min mark.
The FES was
verified as good and the count only suffered a 1 min delay
with this problem. APU prestart
was complete at 1:32am.
completed at 1:34am. Launch occured at 1:38am EST.

Negative Return called at 1:42am EST, all 3
SSME's performed well. At T+6min Endeavour
was at 367,000ft altitude
and 335nm downrange. At T+7min Endeavour was
at 359,000ft and 354nm
downrange, traveling at 11,200mph. At T+8:30, (1:47am EST) the Space
Shuttle Main Engines (SSME) cutoff

at 16,700mph, 800nm downrange. External Tank

- Earlier during the STS-67

was removed from Endeavour and replaced
with one from Discovery . On 02/23/95,
troubleshooting was done

At 1:05pm EST the port Payload Bay Door was closed with
the remaining door closed and latched by 1:08pm EST. At 3:35pm EST,
Endeavour was given a go for deorbit burn with

MCC Status Report # 30
reports: Endeavour had 3
scheduled KSC landing opportunities for
Friday 3/17/95 (1:53pm CST on orbit
246, 3:30pm CST
on orbit 247 and
5:07pm on orbit 248)
but they have been waived off due to bad weather
at the Kennedy Space Center.
NASA managers elected not to call up
landing support at the backup landing site at Edwards Air Force Base
in California for Friday and would keep the
astronauts aloft for an
extra day in the event weather prevents a landing in Florida.
- For Saturday, backup landing support at Edwards has been activated
and there were 6 landing opportunities for March 18, 1995.
at 2:18pm CST on orbit
261, Edwards landing at 3:47pm CST on orbit 262
and another KSC opportunity at 3:55pm CST. Two other Edwards landings
and one KSC landing opportunities exist later in the day.
