Trailing the spacecraft SPARTAN, Discovery is
slowly closing on the SPARTAN platform, which was
deployed yesterday. The Space Shuttle Discovery
performed a series of three engine firings early this
morning. The first two engine firings were to align
the shuttle and the third dropped the shuttle to a
lower orbit to begin its approach back to the
SPARTAN spacecraft.
The SPARTAN spacecraft is pointing its instruments
toward the sun and is gathering science data on the
solar wind that is generated by the corona.
Discovery's crew members will retrieve the free-
flying spacecraft and its solar instruments and
return it to the payload bay early Tuesday.
The ATLAS-2 payload is still providing an
opportunity for scientists from around the world to
receive data concerning the Earth and its
atmosphere. Instruments on board the Space
Shuttle Discovery operated throughout the night,
sending back information regarding the conditions of
the Earth's ozone.

NASA recently announced the selection of the science
team for the Clementine mission. Clementine,
sponsored by the Strategic Defense Initiative Office
(SDIO), is scheduled to be launched in January 1994.
This spacecraft will orbit the moon for several
months and visit an asteroid.
Clementine's mission objectives are to test new,
lightweight sensors in a space radiation environment
and to demonstrate autonomous navigation and
spacecraft operation.
The science team members plan to take the scientific
data received from the Clementine mission and put it
in a form that is easily accessible to the planetary
science community.

STS-56 Status Report #12
MISSION CONTROL CENTER
Monday, April 12, 1993, 5 a.m. CDT
This morning Discovery began slowly closing on the SPARTAN platform, deployed
early yesterday, for a retrieval of the satellite and its solar instruments
scheduled for early Tuesday.
Discovery performed a series of three engine firings during the early morning
hours today, the first two to align the shuttle and the third, which dropped
the shuttle to a lower orbit and began its approach back toward SPARTAN.
Discovery obtained a maximum distance of about 171 nautical miles behind
SPARTAN before it began its return to the satellite. Discovery is now catching
back up to SPARTAN at a rate of about 14 nautical miles per orbit.
Discovery will continue its slow approach back to SPARTAN throughout the day,
with a few small engine firings planned this evening to ensure the shuttle is
aligned with its target and closing on it at the proper rate. At about 12:14
a.m. Tuesday, an engine firing will be performed that will begin Discovery's
close operations with SPARTAN, culminating in a grasp of the platform with the
mechanical arm at bout 2:17 a.m.
The information gathered by SPARTAN's solar instruments is being recorded
onboard the satellite and will be analyzed by scientists after Discovery lands.
Discovery is currently in a 161 by 156 nautical mile high orbit.

ATLAS 2 Status Report #09

Spacelab Mission Operations Control
Marshall Space Flight Center
Huntsville, Alabama
The second mission of the Atmospheric Laboratory for Applications
and Science (ATLAS 2) is providing an opportunity for scientists
from around the world to gather data about our planet and its
atmosphere. Instruments on board Space Shuttle Discovery operated
throughout the night, sending back information about the conditions
of the Earth's protective blanket.
Investigators for the Shuttle Solar Backscatter Ultraviolet (SSBUV)
experiment have been compiling a precisely calibrated database of
global stratospheric ozone measurements. SSBUV, which compares
solar ultraviolet radiation with the amount of sunlight scattered
off the Earth's surface, records the amount of global cloud
coverage in order to determine if the backscatter is caused by
clouds or by specific molecules present in the atmosphere.
A primary objective of SSBUV during the ATLAS series of missions is
to provide highly accurate ozone measurements that will be used to
verify data being obtained by free-flying satellites. SSBUV
readings will help scientists solve the problem of data accuracy
caused by calibration drifts in ozone-sensing instruments that are
exposed to the environment of space for long periods of time.
The Atmospheric Trace Molecule Spectroscopy (ATMOS) continued to
study the atmosphere last night. Scientists want to learn more
about the components of the middle atmosphere, how they interact,
and how they change over time. Models of stratospheric chemistry
are used to predict the future evolution of this atmospheric
region, and ATMOS data will help in the evaluation of those models.
A portion of ATMOS data, earlier recorded onto the Spacelab High
Data Rate Recorder and then downlinked using a newly developed
procedure, was sent to the Jet Propulsion Laboratory for analysis.
A team of scientists for the ATMOS experiment has completed their
evaluation of that data and found it to be of good quality. The
method of transmitting data at one-sixteenth the rate it is
acquired will continue for the rest of the mission to provide
additional data to that recorded on the on-board dedicated
recorder.
The Millimeter-wave Atmospheric Sounder (MAS) measured the
atmosphere's thermal radiation in the 61 to 204 gigahertz frequency
range overnight. MAS uses a parabolic antenna to gather
millimeter-wave radiation and directs that data to the Shuttle's
onboard electronics storage facility where it is downlinked via the
tracking and data relay satellite system.
The information provided by these MAS measurements and by
correlative measurements with the Upper Atmosphere Research
Satellite (UARS) helps scientists understand more about the Earth's
middle atmosphere. In particular, MAS measures the ozone and water
vapor profiles in the stratosphere and mesosphere and performs
global measurements of chlorine monoxide. Since chlorine monoxide
is a key substance involved in the destruction of ozone,
scientists are very interested in finding out how much of this
chemical is present in the atmosphere.
MAS, ATMOS and SSBUV will continue their observations of the
Earth's atmosphere during the next 12 hours.

STS-56 Status Report #13
MISSION CONTROL CENTER
Monday, April 12, 1993, 12 noon CDT
Discovery continued to close on the SPARTAN satellite as the crew conducted
attitude maneuvers designed to put the two spacecraft about 35 feet apart at
the time of its retrieval scheduled for shortly after 2 a.m. central tomorrow.
The orbiter currently is trailing SPARTAN by about 130 statute miles and is
closing in at a rate of 15 miles per orbit.
SPARTAN is a self-contained, free-flying platform that measures the solar wind
and the Sun's corona while deployed away from Discovery.
In between those maneuvers, the Blue Team of crew members, Ken Cameron, Steve
Oswald and Ellen Ochoa made several contacts with schools around the country
using the on-board ham radio equipment.
The school contacts today included the Bellingham Public Schools in Washington
and Parkway Middle School in La Mesa, California.
An excited Cameron radioed down that he could see the flight controllers in
Mission Control using the fast scan television feature of the Shuttle Amateur
Radio Experiment equipment as Discovery flew over Houston.
In its spare time, the crew has been evaluating for the first time a new
on-orbit printer that is designed to eventually replace the older methods of
sending printed data and images to Space Shuttle crews. Called the thermal
impulse printer system, or TIPS, this commercial off-the-shelf unit cost one
tenth of a newly developed system.
Discovery's systems continue to work well allowing the crew to devote its full
attention to the many experiments on going aboard the spacecraft.
