Yee) Subject: Space age learning tools available (Forwarded) Terri Sindelar Headquarters, Washington, D.C. (Phone: 202/453-8400) February 19, 1991 Barbara Schwartz Johnson Space Center, Houston (Phone: 713/483-5111) 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. ------------------------------ Date: Wed, 20 Feb 91 18:37 CST From: Bill Higgins-- Beam Jockey Subject: Bargain on Newton's texts!

(Phone: 407/867-2468) C91-h 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. ------------------------------ X-Delivery-Notice: SMTP MAIL FROM does not correspond to sender.

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. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@mars.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | Is it mind over matter, ___| | | | |__) |/ | | |___ M/S 301-355 | or matter over mind? /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | Never mind. |_____|/ |_|/ |_____|/ | It doesn't matter. ------------------------------ Date: 20 Feb 91 02:27:45 GMT From: elroy.jpl.nasa.gov!jato!mars.jpl.nasa.gov!baalke@decwrl.dec.com (Ron Baalke) 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. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@mars.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | Is it mind over matter, ___| | | | |__) |/ | | |___ M/S 301-355 | or matter over mind? /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | Never mind. |_____|/ |_|/ |_____|/ | It doesn't matter. ------------------------------ End of SPACE Digest V13 #179 *******************
