    Дата: 09 февраля 1998 (1998-02-09) От: Alexander Bondugin Тема: PEGASUS/SNOE LAUNCH FROM VANDENBERG POSTPONED Привет всем! Вот, свалилось из Internet... NASA News National Aeronautics and Space Administration John F. Kennedy Space Center Kennedy Space Center, Florida 32899 ________________________________________________________________________ ____________________________________ For Release: Bruce Buckingham Feb. 5, 1998 Kennedy Space Center, FL George H. Diller Vandenberg Air Force Base, CA KSC Release No. 30 - 98 PEGASUS/SNOE LAUNCH FROM VANDENBERG POSTPONED Senior launch managers from NASA, Orbital Sciences Corporation and the U.S Air Force met today and decided to reschedule the launch of the Student Nitric Oxide Explorer (SNOE) spacecraft. Launch had been tentatively planned for the evening of Feb. 5 aboard a Pegasus rocket from Vandenberg Air Force Base, CA. Also aboard the Pegasus is the Batsat communications satellite for Orbital Sciences. At this time, observed and forecast weather conditions make a launch attempt unlikely in the next few days. In reviewing the range launch schedule, managers determined that the next flight opportunity for this mission is anticipated to be during the week of Feb. 15. A more definite launch date will be determined as new schedules are developed and coordinated during the next week. SNOE is an Earth-orbiting satellite designed and built by a team of University of Colorado at Boulder students, faculty and engineers who were selected to develop the mission by the Universities Space Research Association with funding from NASA. SNOE carries an ultraviolet spectrometer and two photometers to measure the effects of the sun's x-ray radiation and magnetic field on nitric oxide production. This is believed to effect the variability in the Earth's upper atmosphere. -- end - For automatic e-mail subscriptions to daily Shuttle status reports or KSC originated press releases, send an Internet electronic mail message to: domo@news.ksc.nasa.gov.

    Дата: 09 февраля 1998 (1998-02-09) От: Alexander Bondugin Тема: This Month On Galileo - February 9 - March 8, 1998 Привет всем! Вот, свалилось из Internet... THIS MONTH ON GALILEO February 9 - March 8, 1998 Galileo is scheduled for a close flyby of Jupiter's moon Europa on February 10, a few days before entering a 2-1/2 week period of limited communications with Earth caused by solar conjunction. During conjunction, the sun passes between Earth and the spacecraft and only radio science data is collected during this flyby. Until this period of limited communications begins, the spacecraft will process and transmit to Earth pictures and other science information gathered during the previous Europa flyby in December 1997. Transmission of that data, stored on an onboard tape recorder, will resume after the conjunction period ends. During the week of Feb. 9, the spacecraft flies through the Jupiter system for the second time of the Galileo Europa Mission. Prior to reaching any of the bodies in the Jupiter system, the spacecraft performs regular maintenance on the onboard tape recorder and on the propulsion system. These maintenance activities are performed periodically to keep the spacecraft in good operating shape. The closest point to the moon Ganymede is reached first, late Monday night, Feb. 9, at a distance of about 630,000 kilometers (392,000 miles). The close flyby of Europa occurs at 9:57 a.m. (PST) at a planned altitude of 3552 kilometers (2208 miles). The radio science investigation is the only source of new science data during this flyby. For 20 hours surrounding the point of closest approach, the team will monitor Galileo's radio signal for changes in radio frequency due to Europa's gravitational pull on the spacecraft. By using the Doppler effect and measuring these changes, the radio science team will be able to refine the map of the gravity field produced by Europa. This map has been created with data from previous orbits and will continue to be updated with data from subsequent orbits. Five hours after the point of closest approach to Europa, the spacecraft flies through the point of closest approach to Jupiter. This will occur at a distance of approximately 8.9 Jupiter Radii (640,000 kilometers or 395,000 miles) from the gas giant. The closest approach distances to the moons Io and Callisto occur on Wednesday at distances of 440,000 kilometers (273,000 miles) and 2.3 million kilometers (1.4 million miles), respectively. Following the spacecraft flythrough of the Jupiter system, the spacecraft will execute, if needed, a flight path correction. This maneuver, planned for Friday, Feb. 13, will correct any errors in the spacecraft's orbital path that have been accumulated since the previous flight path correction, prior to the close flyby of Europa. Toward the end of the day on Friday, the spacecraft will enter a period of limited to no communication with Earth. This period will last approximately two and a half weeks and is a result of the sun passing between Earth and Jupiter (where the spacecraft is orbiting). This period is known as solar conjunction and occurs when the sun, as it passes between Earth and Jupiter, is close to the path traveled by radio signals as they go from the spacecraft to Earth and vice-versa. As radio signals pass close to the sun, they are affected by solar activity and become noisy or garbled and less data can be safely transmitted to Earth. Because of the reduction in the amount of information that can be successfully transmitted to Earth, the project team has decided not to gather new science data during the flyby of Europa that is planned for this week. In its place, the available transmission time will be dedicated to the continued return of science data gathered during the December 1997 flyby. The processing and transmission schedule only contains one observation during the entire period covered by this edition of This Week on Galileo. This is caused primarily by a reduction in transmission volume surrounding these days of limited communcations. The single observation was performed by the Near Infrared Mapping Spectrometer and covers an area of Europa characterized by the Pwyll crater. The data contained in this observation will allow scientists to learn more about the materials that make up this region of Europa. The next update to This Week on Galileo will occur in 4 weeks. Come back on March 9 for the latest news on Galileo! Note: All times of day listed correspond to the Pacific Time zone and spacecraft event time. Radio signals indicating that an event has occurred on the spacecraft reach the Earth 35 to 50 minutes later, depending on the time of year.

    Дата: 09 февраля 1998 (1998-02-09) От: Alexander Bondugin Тема: STARDUST Update - February 6, 1998 Привет всем! Вот, свалилось из Internet... STARDUST Status Report February 6, 1998 Ken Atkins STARDUST Project Manager Today (February 6) marks 365 days to Launch! The system assembly and test activities (aka "ATLO") continue to move very well at Lockheed-Martin's Astronautics Co. in Denver. The Key this week was the installation of the Power Control Assembly (PCA) ATLO Test Unit (ATU) on the spacecraft for electrical power and continuity (EP&C) testing. This testing will begin the process of insuring that the "blood and nervous systems" of the spacecraft, power and data , are in place and working well. The spacecraft was powered-on at 9 am February 5, 1998. EP&C tests were completed and command & telemetry interface testing has been initiated. Website Feed of ATLO: We are now projecting March 1 for getting the hook-up to this WebSite. We have some software mods to complete. Thanks for your patience. Major Event: The Drop Test of the Structural Thermal Model Sample Return Capsule (SRC) was successfully completed February 5, 1998. This test occurred at the Utah Test and Training Range (UTTR) of the USAF Air Combat Command near Salt Lake City. The drop, from a balloon gondola, began at about 13,000 feet on the drogue parachute. The barometric switches triggered the main parachute on-cue at 10,000 ft., the radar reflector was easily picked up and tracked. Telescopes were also used to observe and film the SRC descent. The landing was extremely "soft." Congratulations to the "Heroes of the 'Salt Flats'." Excellent progress was also made this week on several other activities: * Operations: The Launch and Solar Array deploy command block was delivered to JPL for inclusion in sequence generation (SEQGEN) software. Table top review of the Flight Rules was completed. The Command Dictionary was updated. The flyby targeting process update was completed incorporating the updated Comet Wild-2 dust model. * Navigation Camera: All of the power supplies for the flight unit were delivered this week!! This has been a key critical path item on the delivery path. 'Til next week.........

The current Mir crew consists of Commander Anatoly Solovyev, Flight Engineer Pavel Vinogradov, Talgat Musabayev RO3FT, Nikolai Budarin, RV3DB and R4MIR, American Andy Thomas, KD5CHF, and Frenchman Leopold Eyharts, who is aboard Mir for a 3 week stay. The next shuttle docking mission is currently scheduled for 28-May-98. The Mir packet radio PMS and the SAFEX II repeater are both currently turned off for the time being. The Mir crew has just been too busy with other higher priority projects to spend much time adjusting parameters on the TNC. The Mir crew has information required to reconfigure the new TNC, and we are just waiting for the crew to find an open slot in their schedule to load in the correct parameters. While the Amateur Radio Station on Mir has been turned off, the crew may still turn it back on to make random contacts with groundstations. MIREX was informed by MAREX that the Mir crew is expected to be very busy until after crew 24 returns to earth. MIREX would like the stations monitoring the PMS to please be patient while proper adjustments are made to the packet radio terminal node controller. MIREX has created an Internet Web page containing information regarding Mir and the various Amateur Radio experiments proposed for the space station. The pages are still "under construction", but some good information can be gathered from what has been put together so far.
