    Дата: 12 мая 1998 (1998-05-12) От: Alexander Bondugin Тема: Make an IMPACT: NSS and "Deep Impact" Creators Launch Comet Campaign Привет всем! Вот, свалилось из Internet... FOR IMMEDIATE RELEASE May 7, 1998 Contact: Karen Rugg National Space Society 202-543-1900, ext. 77 Warren Betts Paramount Pictures 310-479-1305 NATIONAL SPACE SOCIETY AND CREATORS OF "DEEP IMPACT" ANNOUNCE CAMPAIGN TO COLLECT ONE MILLION NAMES FOR COMET MISSION Public invited to go to <http://www.nss.org/impact> to "Make an IMPACT" (Washington, DC) -- May 7 -- The National Space Society, along with Paramount Pictures and DreamWorks Pictures, today announce a joint online campaign to collect one million names to be placed on board a spacecraft that will intercept an actual comet. The campaign, "Make an IMPACT," is being launched in time for tomorrow's nationwide release of the film, "DEEP IMPACT," and will continue through the summer or until the one million mark is met. The spacecraft, STARDUST, is being prepared for launch by NASA and the Jet Propulsion Laboratory to intercept Comet Wild-2, collect samples and return to Earth. The names will be printed onto a microchip to be placed aboard the craft later this year. Already on the chip are the names of every member of the National Space Society, and the names of the cast and crew of "DEEP IMPACT." Names can be submitted by going to the National Space Society website at nss.org/impact or to the film's website at deep-impact.com. "We are firm believers in the idea that, today, fact can be as spellbinding as fiction," said Ms. Pat Dasch, executive director for the National Space Society. "In this case, a film tells a fictional story of an impending comet collision while, in fact, NASA and JPL are preparing a craft to intercept a comet and learn more about it. We are very pleased to be partnering with Paramount on this project; with a one million name goal, we're committed to making a real 'impact.'" The National Space Society is also producing a slide set for educators on comets and asteroids, featuring text prepared by leading scientists. The set will include several images from "DEEP IMPACT." The National Space Society, founded in 1974, is an independent, nonprofit space advocacy organization headquartered in Washington, DC. Its 23,000 members and 90 chapters around the world actively promote a spacefaring civilization. Information on NSS and space exploration is available at <http://www.nss.org/>. "DEEP IMPACT" is a contemporary action thriller about the chaos that ensues when it is discovered that a comet is on a deadly collision course with the Earth. DreamWorks Pictures and Paramount Pictures present "DEEP IMPACT," a Zanuck/Brown production, directed by Mimi Leder. The executive producers are Oscar-winner Steven Spielberg, Joan Bradshaw and Walter Parkes. The film is written by Michael Tolkin and Bruce Joel Rubin. DreamWorks SKG is a multi- faceted entertainment studio formed in October 1994 by Steven Spielberg, Jeffrey Katzenberg and David Geffen. Paramount Pictures is part of the entertainment operations of Viacom Inc. ### Hа сегодня все, пока! =SANA=
    Дата: 12 мая 1998 (1998-05-12) От: Alexander Bondugin Тема: Cassini Update - May 8, 1998 Привет всем! Вот, свалилось из Internet... CASSINI SIGNIFICANT EVENTS FOR WEEK ENDING 05/08/98 Spacecraft Status: The Cassini spacecraft is presently traveling at a speed of approximately 145,000 kilometers/hour (~90,000 mph) relative to the sun and has traveled approximately 580 million kilometers (~359 million miles) since launch on October 15, 1997. The most recent Spacecraft status is from the DSN tracking pass on Wednesday, 05/06, over Goldstone. The Cassini spacecraft is in an excellent state of health and is executing the C7 sequence nominally. Inertial attitude control is being maintained using the spacecraft's hydrazine thrusters (RCS system). The spacecraft continues to fly in a High Gain Antenna-to-Sun attitude. It will maintain the HGA-to-Sun attitude, except for planned trajectory correction maneuvers, for the first 14 months of flight. Communication with Earth during early cruise is via one of the spacecraft's two low-gain antennas; the antenna selected depends on the relative geometry of the Sun, Earth and the spacecraft. The downlink telemetry rate is presently 40 bps. Spacecraft Activity Summary: On Friday, 05/01, part two of Solid State Recorder (SSR) Flight Software Partition maintenance was performed. Part one occurred on 04/28 as part of the background sequence. This activity repaired SSR double bit errors (DBEs) which had occurred in the code-containing portions of the Flight Software partitions during the preceding period. Friday's real-time command based portion of the activity cleared telemetry flags and sent down the results of the maintenance activity. The Reaction Wheel Assembly Exercise also occurred on Friday, as planned. On Saturday, 05/02, data from the Radio Plasma Wave Subsystem (RPWS) Venus-1 activity was successfully played back. A separate news release will detail the results of the RPWS experiment. On Sunday, 05/03, data from the Radar Venus-1 engineering test was successfully played back. Results have confirmed that the RADAR instrument's electronic components functioned end-to-end, which was the objective of the test. Also on Sunday, the Attitude and Articulation Control Subsystem Inertial Vector Propagation (AACS IVP) vector update was successfully performed. This update is a maintenance activity, performed as needed based on the geometry of the trajectory. On Tuesday, 05/05, the Solid State Recorder record and playback pointers were reset, according to plan. This housekeeping activity, done approximately weekly, maximizes the amount of time that recorded engineering data is available for playback to the ground should an anomaly occur on the spacecraft. On Wednesday, 05/06, the first portion of the Stellar Reference Unit-A (SRU-A) decontamination activity was performed. Part one of the activity involves powering a heater attached to the SRU radiator for a period of time, inducing volatilization of any contaminants which may have accumulated on the radiator since Launch. The temperature profile followed in the SRU-A decontamination was very similar to that followed by SRU-B which was decontaminated in mid-March. Part two of the activity will be performed on Friday, May 8, and will involve collecting a test star image and powering down SRU-A. Also on Wednesday, the C8 background sequence was successfully uplinked to the spacecraft. The C8 sequence begins on Sunday afternoon, May 10. On Thursday, 05/07, there were no changes in spacecraft configuration. Upcoming events: Activities scheduled for the week of 5/08 - 5/14 include: completion of SRU-A decontamination activity and turn-off of RPWS instrument (5/08), an SSR Pointer Reset and AACS Attitude Estimator readout (5/11), and an SSR Pointer Reset and SSR Flight Software Maintenance (5/13). As noted in last week's report, the Trajectory Correction Maneuver originally scheduled for 5/14 was cancelled due to excellent Navigation during Venus-1 flyby. DSN Coverage: Over the past week Cassini had 9 scheduled DSN tracks, occurring from 05/01 through 5/07. In the coming week there will be 6 DSN passes. Hа сегодня все, пока! =SANA=

    Дата: 12 мая 1998 (1998-05-12) От: Alexander Bondugin Тема: Sky & Telescope News Bulletin - May 8, 1998 Привет всем! Вот, свалилось из Internet... SKY & TELESCOPE'S NEWS BULLETIN MAY 8, 1998 GAMMA-RAY BURST REACHES ACROSS VISIBLE UNIVERSE With the help of the BeppoSAX satellite, the Keck II reflector, and the Hubble Space Telescope, astronomers have shown that a gamma-ray burst (GRB) took place in a galaxy with a redshift of 3.42. This means that the gamma rays traveled for at least 10 billion years before reaching Earth last December 14th. And that, in turn, implies that an energy of 3 x 10^53 ergs was released in the form of gamma rays. That's more than 100 times a supernova's luminous output, and it was released within seconds. The finding may force theorists to revise or abandon the currently favored explanation for GRBs: a pair of coalescing neutron stars. Details were discussed Wednesday at a NASA press conference, and appear in the May 7th issue of Nature. NEW DISTANCE RECORD GALAXY Astronomers announced yet another universal distance record. As mentioned in the June issue of SKY & TELESCOPE (page 16), Esther M. Hu (University of Hawaii) and her colleagues used Keck's Low Resolution Imaging Spectrograph to find emission lines at a redshift of 5.64. This beats the previous record of 5.34 -- made only a few weeks earlier. Details will appear in Astrophysical Journal Letters. COMET STONEHOUSE Comet Stonehouse (1998 H1) is hanging in there at about 11th magnitude, but a bright Moon (full on the 11th) will interfere with viewing. Nevertheless, the comet is well placed in the sky for comet watchers in the Northern Hemisphere. During the upcoming week, the comet moves from Bootes into Canes Venatici, and is thus visible throughout the night and is highest in the sky near local midnight. Here are positions for Comet Stonehouse at 0 hours Universal Time in 2000.0 coordinates: R.A. Dec. May 9 14h 09 +36.2 deg. 11 13 58 +38.5 13 13 47 +40.5 COMET SOHO On May 3rd, the Solar and Heliospheric Observatory (SOHO) satellite discovered its 45th comet. The spacecraft is good at catching "sun-grazing" comets because its telescopes continuously stare toward the Sun. The new interloper, designated C/1998 J1, was caught at the edge of the field of view of SOHO's Large Angle and Spectrometric Coronagraph (LASCO). Usually, Comet SOHOs disappear as they either collide or venture too near the Sun. This one, however, will undoubtedly survive its May 8th 24-million- kilometer closest approach to the Sun. Although the comet is predicted to peak at magnitude -0.8 over the weekend, it will be only 9 degrees from the Sun. By the end of the month, Comet SOHO will move well away from the Sun and still be about 4th magnitude, but only visible from the Southern Hemisphere. For those up for the challenge of spying the comet immediately after sunset as it moves directly above the Sun from midnorthern latitudes, here are 2000.0 coordinates for the coming week: R.A. Dec. May 9 3h 17m +25.3 deg. 11 3 47 +24.3 13 4 13 +21.5 THIS WEEK'S "SKY AT A GLANCE" Some daily events in the changing sky, from the editors of SKY & TELESCOPE. MAY 10 -- SUNDAY * Late this evening, when the Moon is high in the sky, look well to its upper right (by about two fist-widths at arm's length or a bit more) for the star Spica. About the same distance to the Moon's lower left, the orange star Antares is rising. About three fists above the Moon is brighter Arcturus. MAY 11 -- MONDAY * Full Moon (exact at 10:29 a.m. Eastern Daylight Time). * As dawn brightens on Tuesday morning, scan with binoculars just above the eastern horizon for Saturn and Mercury only 1 degree apart. Saturn is to Mercury's left or upper left. MAY 12 -- TUESDAY * During or just after twilight, telescope users in parts of the Southwest and Mexico can try timing an 11th-magnitude asteroid, 25 Phocaea, occulting an 8.3-magnitude star near Spica. The asteroid should black out the star for up to 7 seconds around 7:53 p.m. Mountain Standard Time (that's Arizona time). The tricky part will be finding the star quickly in the fading dusk -- assuming the sky will be dark enough at your location. A finder chart is in the May Sky & Telescope, page 98, and at http://www.skypub.com/occults/occults.html. * Mars is in conjunction behind the Sun. In fact Mars actually passes behind the Sun's disk as seen (or not seen!) from Earth -- something that hasn't happened since 1976. * During dawn Wednesday morning, Saturn is 1 degree above Mercury. MAY 13 -- WEDNESDAY * After the Moon rises late this evening look to its right (by about 1 1/2 fist-widths at arm's length) for orange Antares. Near Antares are fainter white stars of Scorpius. MAY 14 -- THURSDAY * The brightest star very high in the southeast these evenings is Arcturus, pale yellow-orange. Far to its lower right is dimmer Spica, blue-white. In the northeast, a little lower than Spica, is bright white Vega. MAY 15 -- FRIDAY * Some more spring starwatching: Look northwest right after dark this week. The brightest star there is Capella. Far to its upper left are Castor and Pollux, the heads of Gemini, lined up horizontally. To their lower left (and a little nearer to them than Capella is) shines Procyon. MAY 16 -- SATURDAY * The Big Dipper is very high in the north during the evening around this time of year. It's floating upside down. Examine the middle star of its handle, Mizar. Can you see Mizar's tiny companion star, Alcor, barely to its lower right? ============================ THIS WEEK'S PLANET ROUNDUP ============================ MERCURY and SATURN are barely above the eastern horizon as dawn brightens; they're close together well to the lower left of Jupiter and Venus. Scan for them with binoculars! VENUS shines low in the east during dawn, with Jupiter to its upper right. Venus is six times brighter than Jupiter. They're 16 degrees apart on the morning of May 10th and are separating by about 1 degree per day. MARS is in conjunction with the Sun this week, hidden behind its glare. JUPITER is to the upper right of Venus, in the east-southeast during dawn; see above. URANUS and NEPTUNE, magnitudes 6 and 8, respectively, are in Capricornus in the southeast before dawn. See the finder chart in the May Sky & Telescope, page 96. PLUTO, magnitude 13.7, is near the Ophiuchus-Scorpius border. It's well up in the southeast by 11 p.m. See the finder chart in the May Sky & Telescope, page 97. The finder charts for Uranus, Neptune, and Pluto are also at http://www.skypub.com/whatsup/urnepl98.html. (All descriptions that relate to the horizon or zenith are written for the world's midnorthern latitudes. Descriptions that also depend on longitude are for North America.

STARDUST Status Report May 8, 1998 Ken Atkins STARDUST Project Manager Assembly, Test, and Launch Operations (ATLO) activities: ATLO this week involved installation of the Solar Array Switching Unit (SASU), the test battery, and making harness modifications for the Navigation Camera. The Sample Return Capsule (SRC) spin balance testing and ballasting was successfully completed. The total SRC mass is about 46 kg (101 lbs). Outreach: The Project in collaboration the National Space Society, along with Paramount Pictures and DreamWorks Pictures, today announced a joint online campaign to collect one million names to be flown round-trip to comet Wild 2 onboard the Stardust Sample Return Capsule. The campaign, "Make an IMPACT," is being launched in time for todays's nationwide release of the film, "DEEP IMPACT," and will continue through the summer. The names will be printed onto a microchip to be placed aboard the craft later this year. Already collected are the names of every member of the cast and crew of "DEEP IMPACT." Names can be submitted by going to the National Space Society website at http://nss.org/impact, the film's website at http://deep-impact.com, or the signup page on the Stardust website: http://stardust.jpl.nasa.gov/microchip/signup.html. The Stardust Educator Fellowship Workshop was held this week at Lockheed Martin Astronautics (LMA) in Denver. This workshop involved the initial 10 Stardust Fellowship winners from 10 states. They were exposed to three days of intensive training on the mission and its science. The Principal Investigator, Project Manager, LMA's Flight System Manager, and LMA's VP for Flight Systems participated along with a number of the Stardust team scientists and engineers. The training is central to Stardust's nationwide teacher training initiative aimed at grades 4-8 and focused on teaching students about small solar system bodies such as comets and the engineering adventures to explore them. The core Educator Fellows will return to their districts with materials and curricula to use with their own students and to provide training for other teachers. An additional 15 Fellows will be chosen in the fall. Stardust's Fellows Program is part of an educational outreach partnership between the Project, the Virginia-based Challenger Center for Space Science Education; the JASON Foundation for Education headquartered in Waltham, Mass.; and Omniplex Science Museum, Oklahoma City, OK.

    Дата: 12 мая 1998 (1998-05-12) От: Alexander Bondugin Тема: Hughes Satellite On Its Way To The Moon Привет всем! Вот, свалилось из Internet... HUGHES GLOBAL SERVICES, INC. HUGHES SPACE AND COMMUNICATIONS COMPANY Communications and Customer Relations P.O. Box 92919 (S10/S323) Los Angeles, CA 90009 Media Relations (310) 364-6363 Investor Relations (310) 662-9688 www.hughesglobal.com www.hughespace.com HUGHES SATELLITE ON ITS WAY TO MOON LOS ANGELES, May 8, 1998 -- The HGS-1 satellite fired its motor at 5:42 p.m. PDT yesterday, heading off on its 9-day journey around the moon and back to Earth orbit. This is the first known lunar mission involving a communications satellite and the first mission financed by a non-governmental entity. Controllers in the Hughes Mission Control Center in El Segundo, Calif., have confirmed that the spacecraft is on its way, by using signals received at ground stations and images seen by optical telescopes around the globe. The satellite reached a maximum speed of 24,000 mph after the firing to send it on its nearly 6-day outbound trip. On May 13, it will pass behind the moon, coming as close as 5,000 miles above the surface. With an assist from lunar gravity, it will swing around the moon, change directions and head off on its 3-day return trip to Earth. On May 16, satellite controllers will begin braking maneuvers to help the satellite settle into an orbit around the equator. HGS-1 is an HS 601HP model satellite built by Hughes Space and Communications Company of Los Angeles. It was designed to provide television and other telecommunications services for Asia and neighboring regions. During its launch last Christmas Day, however, the rocket that was carrying it malfunctioned, leaving the satellite in an unusable, highly inclined, elliptical orbit. The satellite itself is fully functional, with 44 high-power transponders in C- and Ku-band. After the launch failure the original owner of the spacecraft filed an insurance claim. The insurers declared the spacecraft a total loss for its original purposes. Scientists and engineers from Hughes Space and Comm and its subsidiary, Hughes Global Services, Inc., (HGS), devised a salvage mission using the moon to move the satellite into a usable circular orbit. HGS has obtained the title to the spacecraft, with the agreement to share profits with the insurers if the satellite can be put to use. During the last several weeks, Hughes controllers have fired the satellite's onboard rocket motor several times to raise its altitude. Thursday's was the 12th firing, and it burned for almost 2 minutes to give HGS-1 its final kick toward the moon. Controllers may use short burns during the 9-day cruise to make minor adjustments in the flight path. The commands for the final firing were sent to the spacecraft about 2 a.m. PDT Thursday, and HGS-1 executed the maneuver while out of view from the ground stations. Controllers were able to confirm the motor firing within about half an hour, and within another hour verified that HGS-1 was on the correct trajectory. Hughes Space and Comm, a unit of Hughes Electronics Corporation, has been building communications and scientific spacecraft and instruments for more than 35 years. It is the world leader in manufacturing commercial geostationary communications satellites. Hughes Global Services packages commercial satellite services for government and military customers. HGS also works with other Hughes Electronics companies to provide end-to-end solutions for underserved commercial markets. The earnings of Hughes Electronics are used to calculate the earnings per share attributable to GMH (NYSE symbol) common stock. Hа сегодня все, пока! =SANA=
    Дата: 12 мая 1998 (1998-05-12) От: Alexander Bondugin Тема: This Week On Galileo - May 11-17, 1998 Привет всем! Вот, свалилось из Internet... THIS WEEK ON GALILEO May 11-17, 1998 Galileo spends most of the week processing and transmitting to Earth science information stored on the spacecraft's onboard tape recorder. All of the data on this week's schedule contains information describing Jupiter's icy moon Europa. The data set returned this week was gathered by the spacecraft's camera, near-infrared spectrometer and suite of fields and particles instruments during the spacecraft's close flyby of the moon, just over 6 weeks ago. Some data from last week's schedule slipped into this week when Galileo released antenna time at the Deep Space Network's 70-meter antenna in Canberra, Australia. The antenna time was released to support radio frequency observations of the newly identified gamma ray burst you may have heard about in the news. The burst was located in a relatively close galaxy and the Canberra antenna was considered a key part for very long baseline interferometry (VLBI) observations required to study the event. Last week's efforts to change the attitude control computer's onboard software have encountered a glitch. It appears that the onboard software was successfully modified, but the effect on the gyroscopic data is not as expected. The flight team will continue to gather and analyze spacecraft engineering data to determine what went wrong. Another gyroscope performance test is scheduled this Friday. This week's information processing and transmission activities continue to retrieve data from a section of the onboard tape recorder that has already been accessed once this orbit. This second processing and transmission opportunity allows data gaps to be filled, re-processing of data with different parameters, or selection of entirely new data. On the data return schedule we find two observations by the spacecraft's camera of a region of Europa characterized by dark spots. Together they will provide a stereo topographic view of the area. The camera team also returns an observation of a region containing characteristic triple bands. Finally, the camera team returns an observation designed to provide photometric measurements of Europa's surface. Photometry is the measurement of light intensities which can then be used to help identify the different materials on the surface of Europa. The near-infrared spectrometer team contributes to this week's schedule by scheduling the return of an observation of a region of Europa containing dark spots and pull-apart wedges. The observation is expected to provide more information on the materials that make up this region of Europa. Finally, the fields and particles instruments return measurements that will add to the repository of information describing the interaction of Jupiter's magnetic and electric fields with Europa.
