Yesterday, NASA official announced launch dates for the STS-55 and STS-56
missions. Space Shuttle Discovery with the STS-56/ATLAS 2 payload is scheduled
to launch April 6, 1993 at 1:32 a.m. EDT. Space Shuttle Columbia and the STS-
55/Spacelab D-2 payload has been assigned a new target launch date of no
earlier than April 24. STS-55 experienced a launch scrub on March, 22.
In order to have Space Shuttle Columbia ready for its scheduled launch, all
three main engines are being removed and will be replaced with the engines from
the Space Shuttle Endeavour. As a result of the various launch schedule
changes, the STS-57 mission is now targeted to fly in late May. The remaining
Space Shuttle missions will stay in their respective flight order and schedule.

Magellan continues to survey the gravitational field of Venus. Final global
maps of Venus's surface topography and various surface properties were released
at the Lunar and Planetary Conference in mid-March.
The Galileo spacecraft is scheduled to enter Jupiter's orbit on December 7,
1995. Galileo's conditions and performance are excellent except for the fact
that the spacecraft's high-gain antenna is only partly deployed. The science
and engineering data are being transmitted via the low-gain antenna.
Topex/Poseidon satellite it is healthy and all scientific instruments are
performing normally. The mission to map ocean circulation has produced
interesting results about the Central Pacific "El Nino" phenomenon which were
presented in late February.
Ulysses, Galileo and the Mars Observer spacecrafts are performing a joint
radio-science gravity-wave experiment which began March 22 and will continue
until April 12.

growers will use aerial and satellite images to battle an insect problem
affecting California's $10 billion-a-year wine industry.
Sensitive electronic scanners on aircraft and satellite will aid a team from
government, industry and several universities who plan to map and analyze root
louse damage in northern California's wine growing region this summer.
About 65 percent of Napa and Sonoma counties' vineyards are planted with a
grape rootstock vulnerable to a new strain of phylloxera. Phylloxera is an
aphid-like insect that kills grapevines by sucking juice from the plants'
roots.
Satellite and aircraft scanners can map large areas. When combined with a
computerized geographic data base, they will provide crucial overviews of
phylloxera spread patterns.
The GRAPES project is staffed by the Earth System Science Division at Ames.
Funding is provided by the Office of Advanced Concepts and Technology, here at
headquarters.

UFO INFORMATION
SPACELINK NOTE: This statement is excerpted from QUESTIONS AND ANSWERS About
Aeronautics and Space, which can be found under main menu 7, item 10.
----------------------------------------------------------------------
Q: DO UFO's REALLY EXIST?
A: NASA has no factual knowledge about UFO's, nor any data
on possible life-forms on other planets. We do conduct
the HRMS program (High Resolution Microwave Survey)
via powerful radio receivers and sophisticated computerized
recognition systems, in a constant watch for broadcasts from
another star system.

GASPRA ANIMATION (GASPRA.FLI)
This animation consists of 11 images taken by the Galileo
spacecraft as it flew by the asteroid 951 Gaspra on October 29, 1991.
The animation shows Gaspra growing progressively larger in the field
of view of Galileo's solid-state imaging camera as the spacecraft
approached the asteroid. Sunlight is coming from the right.
Gaspra is roughly 17 kilometers (10 miles) long, 10 kilometers
(6 miles) wide.
The first frame of the animation (smallest image) was taken
5 3/4 hours before closest approach when the spacecraft was 164,000
kilometers (102,000 miles) from Gaspra, the last frame (largest image)
at a range of 16,000 kilometers (10,000 miles), 30 minutes before closest
approach.
Gaspra spins once in roughly 7 hours, so these images
capture almost one full rotation of the asteroid. Gaspra spins
counterclockwise; its north pole is to the upper left, and the
"nose" which points upward in the first image, is seen rotating
back into shadow, emerging at lower left, and rotating to upper
right. Several craters are visible on the newly seen sides of
Gaspra, but none approaches the scale of the asteroid's radius.
Evidently, Gaspra lacks the large craters common on the surfaces
of many planetary satellites, consistent with Gaspra's
comparatively recent origin from the collisional breakup of a
larger body.

Earth/Moon Animation (EMCONJ.FLC)
EMCONJ.FLC is in Autodesk Animator .FLI format for MSDOS PCs and the X
windowing system. The file can be viewed using the PLAY79 program for
MSDOS.
This is part of a time-lapse sequence taken by the Galileo spacecraft on
December 16, 1992, eight days after its flyby of the Earth/Moon system en route
to Jupiter. The full color sequence utilized the 0.968, 0.727 and violet
filters; this reduced, black-and-white version was made with the 0.968 micron
filter so that both vegetated and unvegetated land masses appear bright in
contrast to the oceans. The 46 frames span 15 hours of motion by the Earth,
Moon and spacecraft as viewed from the perspective of Galileo, with South at
the top. Visible are the Pacific basin, Australia, Southeast Asia, India, and
finally Arabia and the horn of Africa. A remarkable feature of this sequence is
the specular reflection or sun glint from the sea surface. Depending on the
roughness of the water the extent of specular reflection varies rapidly,
expanding over rough seas and contracting to a point over still oceanic pools
such as near the west coast of Australia.

VENUS ANIMATION (VENUS.ZIP)
The "venus.zip" contains a compressed animated "rotating globe" of
Venus based on the topography (surface elevation) data collected
by NASA's Magellan mission. The animation is in FLI format and consists
of 72 frames of 200x200 pixels every 5 degrees around the planet's equator.
The surface elevation is color coded so that the highest elevations
appear bright, while the lowest appear dark. The colors approximate
the colors actually seen on the surface by the Soviet Venera landers.
The venus.zip file was compressed with PKZIP. The frames were created
by re-projecting the sinusoidal "browse" image of surface topography from
the GxDR CD-ROM of Magellan's data from Cycle 1. Some data from Cycle 2 is
included in this browse image to partly fill gap in Cycle 1 coverage caused
by Superior Conjunction. The dark areas represent regions not yet
mapped at the time the CD-ROM was made.
