Jonathan's Space Report Feb 21, 1989 (No. 4) As reported last week, the first US launch of the year went off perfectly. The Navstar 2-1 satellite has now circularised its orbit at 20000 km altitude. The next Navstar /Delta 2 launch is set for April. The Soviet Union launched a robot cargo freighter on 10 Feb to deliver food, air, fuel and experiments to the Mir space station. The Progress-40 spacecraft linked up with Mir on 12 Feb, and will remain attached to the station for about a month. It will be followed by Progress-41 in March, and then a month of major activity in April when the station will be enlarged by the addition of a new module, and a new crew will take over. Also on Feb 10, the Kosmos-2000 satellite was launched into polar orbit. The second mission of the year to be operated by the Soviet Priroda ("Nature") Center, it will be used to make maps of Antarctica. The space shuttle Discovery is still on target for a mid-March launch at Kennedy Space Center. Other events: 6 satellites (Kosmos-1994 to 1999) were launched on a single Tsiklon ("Cyclone") booster on Feb 10, making a total of 8 satellites launched that day. The small satellites are believed to be used for either geodetic or communications purposes by the Soviet Navy. The Kosmos-1990 satellite completed its mission to survey Armenia and landed in the USSR after 30 days in space.
