SB NEWS @ AMSAT $SPC0620 * SpaceNews 20-Jun-94 * BID: $SPC0620 ========= SpaceNews ========= MONDAY JUNE 20, 1994 SpaceNews originates at KD2BD in Wall Township, New Jersey, USA. It is published every week and is made available for unlimited distribution. * IMPACT WITH JUPITER * ======================== JPL's Galileo spacecraft is scheduled to observe 16 of the 21 possible impacts of the fragments of Comet Shoemaker-Levy-9 with Jupiter this July, according to project scientist Dr. Torrence Johnson. Galileo is scheduled to observe 16 of the 21 possible impacts of the fragments of Comet Shoemaker-Levy-9 with Jupiter this July. Galileo, however, won't be alone in keeping its eyes on Jupiter. Although the Galileo spacecraft will be in the best position to view Comet Shoemaker-Levy-9's impact with Jupiter, Voyager 2 and the Ulysses spacecraft will record various measurements from the event. On its way out of the solar system, Voyager 2 will be heading south, about 6 billion kilometers (3.7 billion miles) from Jupiter, and will have the comet's impact sites in its line of sight. The spacecraft will observe with its ultraviolet spectrometer and planetary radio astronomy instrument, and numerical data will be returned in real time. The Ulysses spacecraft, on its way to explore the sun's polar regions, will be able to make measurements of radio and plasma waves from the comet's impact from its position at about 75 degrees south of the sun's equator and about 800 million kilometers (500 million miles) from Jupiter. JPL's Deep Space Network facility at Goldstone, California will perform radio astronomy on the synchrotron emission from Jupiter's radiation belt, looking for disturbances caused by Shoemaker-Levy dust.

The EO-15 commander and flight engineer, Viktor Afanas'ev and Yuriy Usachyov, will be replaced this month by the EO-16 crew, Yuriy Malenchenko and Talgat Musabaev, who will be launched on the Soyuz TM-19 ferry ship on June 20. Physician-cosmonaut Valeriy Polyakov will remain aboard Mir. Both Malenchenko, a Russian Air Force cosmonaut, and Musabaev, a Kazakh Space Agency cosmonaut, will be on their first flights.

The beacon carrier on 145.810 MHz was also strong at a range of 23000 km. With signals from AO-10 steadily improving, JH0OTM is looking forward to making contacts via AO-10's Mode B transponder. * DOVE NEWS * ============= DOVE-OSCAR-17 continues to exercise its voice capabilities. Downlinks can be heard on 145.825 MHz FM. The following packet frame was received from by spacecraft by KD2BD late last week: DOVE-1>BRAMST : Greetings to attendees at the ARRL National Convention and Education Forum from the DOVE Command Team (WD0E) * SPACE CALENDAR * ================== The following is a tentative calendar of space related events for the next several weeks.
