RELEASE:  91-29

SPACE AGE LEARNING TOOLS AVAILABLE


     Although NASA has been sending humans into space for more than 30
years, spaceflght is still new to middle school children and basic
questions are very much on their minds.  With the help of the Astronaut
Corps, NASA is producing space age learning tools to relate space flight
and other scientific concepts to teachers and students at all grade
levels and subject areas.   NASA today released the first in this new
series of educational video products.  This new video package, Liftoff
to Learning: "Space Basics" illustrates orbital science.

     "Space Basics" was filmed on location at the NASA Johnson Space
Center, Houston, NASA Kennedy Space Center, Fla., and in orbit onboard
Space Shuttle mission STS-41.  The 21-minute video combines the
answers to basic questions with exciting space photography and
colorful special effects.  Accompanying the tape is an 8-page video
resource guide for teachers that provides background information on
rockets and orbits as well as suggestions for hands-on classroom
activities.  The guide also includes a vocabulary list, reference list and
details about the crew members.

     Observing that space captures students interest in science,  math
and technology, NASA is developing a variety of educational materials,
including video tapes, slide sets and educational publications relating
to specific Space Shuttle missions and space flight concepts.  For each
Shuttle mission a 4-page teachers guide, "Mission Watch" will be
produced describing the mission, payloads, experiments, and science
objectives, and includes suggested classroom activities and references.
At the end of the mission, a 4-page summary report, "Mission
Highlights" will be available to educators.

       These new space age learning products are the result of a team
effort involving NASA Headquarter's Educational Affairs Division, the
Astronaut Corps, Space Shuttle Support Office, program and science
people, flight directors and planners, television production people and
public affairs.

     Products currently available include:

o  Liftoff to Learning: "Space Basics" video and teachers guide
   (available March 4)
o  "Mission Watch"  teacher's guides for STS-41 and 35
o  "Mission Highlights" summary for STS-41 and 35
o  STS-35 Astro-1 teachers guide and slide set

     The video Liftoff to Learning, "Space Basics" can be taped at home
or at school by tuning to Satcom F2R satellite, 72 degrees West
longitude, transponder 13.  The video will be transmitted at noon and
repeated at 6 p.m. EST every Tuesday and Thursday in February and will
run periodically thoughout  the month of March.

       Educators can contact NASA's Teacher Resource Centers for
information on obtaining copies of the "Space Basics" videotape and
resource guide (available March 4), "Mission Watch" and "Mission
Highlights."  Videotapes and slide sets are also available by phoning
NASA CORE on 216/744-1051 for information.  And with a modem,
educators can access NASA Spacelink, a computerized space education
data base on 205/895-0028 for all printed education materials.

Concidentally, I recently received the most wonderful piece of junk
mail to cross my desk in a long while.

(And I get a *lot* of junk mail.  I get *Aviation Leak*, so my name is
sold to the Crewcut Republican Weapons Engineers mailing lists.  I
also get *Whole Earth Review*, so I am on the Organic Hippie Relics of
the Sixties mailing lists.)

"Dear Scholar: [hmm, I like these people already]

"...a new microfilm collection, *Sir Isaac Newton: Manuscripts and
Papers*, will soon be available from Chadwyck-Healey.

"...Going beyond the works of physical science, all of Newton's
interests are revealed in this collection; his theological histories,
economic analyses, experiments in alchemy, geography, interpretations
of mythology, commentaries on Scripture and medical treatises.

"Your institution can acquire the complete collection at a
*pre-publication price of $4,500, if an order is placed before
February 28,1991.*  After this date, the price rises to $5000." [Gee,
it isn't every day that somebody offers to save me five hundred bucks!
I begin to daydream.  The entire extant works of Newton... I would be
the only kid on my block to own them... I could do all kinds of
scholarship... how much limit do I have left on my Master Card?]

"Please examine the brochure enclosed.  If you have further questions
regarding the collection or would like to place your order with us,
call our offices in Virginia toll-free at 800-752-0515."

It didn't take long before I came to my senses. But you know, once
you've considered a $4500 impulse buy and rejected it, a lot of other
things look less frivolous.  I've begun to think about the $500 Phobos
globe from Germany again. (-:

(Why did I get this particular solicitation?  I think it's because I
am a member of the American Physical Society's History of Physics
division.)

So, Clayton, if you wre looking for Newton's Scriptural commentary,
now you know where you can get it, along with a whole lot more!

However, containing the insulation flaking with some sort of external
wrapper (necessarily deployed in space) kills two birds with one stone,
because the tank also needs a "meteor bumper" shield to protect it against
other people's orbital debris.

SPACE STATION PROCESSING FACILITY CONTRACT AWARDED

     NASA's Kennedy Space Center, Fla., has awarded Metric Constructors, Inc.,
Tampa,  Fla., a $56,215,000 contract to construct the Space Station
Processing Facility (SSPF).

     Under the terms of the fixed-price contract, Metric Constructors will
build the 457,000-square-foot facility to be used as the central preflight
checkout and processing point for Space Station Freedom elements.

     Located in the KSC Industrial Area just east of the Operations & Checkout
Building, the SSPF will be a KSC-operated facility occupied by about 1,000
NASA and contractor employees.  The 3-story SSPF will include
communications and electrical control areas, laboratories, logistics staging
areas, operational control rooms, office areas and a cafeteria.

     The SSPF will have over 63,000 square feet of dedicated payload
processing space, which includes a high bay and intermediate bay.  A 5,000
square foot airlock will be adjacent to the primary processing area.  Both
the airlock and processing area will be 100,000 parts-per-million rated
clean rooms.

     A visitor viewing window, which will allow NASA tour guests to view
Space Station Freedom preflight operations, also has been designed into the
building's processing area.

     Construction of the SSPF is set to begin on or about April 1 and the
building should be ready for occupancy within 1080 days of the SSPF
groundbreaking.

Re:  Space and Human Destiny Conference

Just a few ideas:

Effects on the Biosphere; less pollution, mining, greenhouse, etc.

Effects on culture;  How would politicians behave if they saw the whole planet
                     every day?  Longer vision?  Delusions of Granduer?

Future Environmental concerns;  "But we should keep Jupiter's moons the way we

                       MAGELLAN STATUS REPORT
                         February 19, 1991

     The Magellan spacecraft is performing nominally.  All STARCALS (star
calibrations) and DESATS (desaturations) during the weekend were successful.

     Later today the weekly upload of the mapping command sequences with the
associated radar control parameter and mapping quaternion files will be
performed.  This sequence will continue the 10 minute shortening of the delayed
mapping swaths.  It will also include commands to offpoint the solar panels
by 90 degrees at the beginning and end of each mapping pass.  This is intended
to reduce the thermal effects of sunlight reflecting off the solar panels on to
the spacecraft bus.

     The spacecraft controllers plan to monitor the temperatures closely for
the first three orbits of the new sequence.  If the offpointing of solar panels
does not produce a leveling or drop in the critical temperatures, additional
steps will be taken to keep the gyros below 70 degrees C.

     Among the options available are (1) turning off the back-up Attitude
Reference Unit (ARU) electronics, and (2) shortening the mapping passes by an
additional 5 minutes.

Subject: Ulysses Update - 02/19/91


                     ULYSSES STATUS REPORT
                        February 19, 1991

     Today, the Ulysses spacecraft is approximately 132 million
miles (212 million kilometers) from Earth.  The spacecraft is
traveling at approximately 60,300 miles per hour (97,100 kilometers
per hour) with respect to the sun as it journeys through the ecliptic
plane on its way to Jupiter.

     The mission remains in the routine operations phase.  A
precession maneuver was conducted on February 7 to improve the
Earth-pointing of the spacecraft's High Gain Antenna.

     On February 1, controllers found that some commands were being
rejected by the spacecraft.  On February 4, all commands were being
rejected by the spacecraft.  The reason for the command rejection
was traced to doppler shifts in the command subcarrier channel.

     The doppler effect is the change in frequency of a received
signal caused by motion between the source of the signal and the
receiver.  Doppler shifts are commonly illustrated by the whistle
of a passing locomotive.  In Ulysses' case, the spacecraft is
moving away from the Earth at a relative speed of nearly 80,000
miles per hour, lowering the frequency of the signal Ulysses
receives from the ground.

     Small adjustments were made to the subcarrier frequency and
the channel's command bit rate, at the tracking station, to
compensate for the doppler effects caused by Ulysses' velocity.
By Februrary 11, commanding was again normal.

     Data collection from the science experiments is now
continuing on a normal basis.  Ulysses is tracked eight
hours each day, during which time real-time data are acquired.
Midway through each eight-hour pass, controllers begin to play
back data acquired while the spacecraft was out of view.

     The wobble caused recently by uneven solar heating of
Ulysses' axial boom has not returned, although flight operators
caution that the motion could recur at any time well into April
of this year.

     The five-year mission to study the Sun's poles and
interstellar space beyond the poles is conducted jointly by
NASA/JPL and the European Space Agency.  The Ulysses spacecraft
is provided by ESA.
