SB SPACE @ ARL $ARLS015 ARLS015 Sputnik 41/RS-18 Launched from Mir ZCZC AS15 QST de W1AW Space Bulletin 015 ARLS015 From ARRL Headquarters Newington, CT November 11, 1998 To all radio amateurs SB SPACE ARL ARLS015 ARLS015 Sputnik 41/RS-18 Launched from Mir Russian cosmonauts launched another mini-Sputnik satellite November 10 during a spacewalk from the Mir space station. The launch of Sputnik 41--also being called RS-18--comes just over a year after the launch of Sputnik 40, which commemorated the launch of the first artificial Earth satellite by the USSR in 1957. Among the first in the US to report hearing the new satellite was Ken Carlstrom, N1WED, in New Hampshire. He reported hearing Sputnik 41 November 11 from approximately 0604 to 0609 UTC on 145.8145 MHz. The Sputnik had arrived on Mir aboard a Progress supply rocket late last month. Sputnik 41 was financed by the Aeroclub de France to mark its centennial as part of a program of satellites made in a collaboration of Russian and French students. AMSAT-France is cooperating with the education department of the Russian Aeronautic Federation to make this latest Sputnik reprise possible. Sputnik 41 broadcasts pre-recorded voice greetings in three languages, French, English, and Russian. The messages say ''1998 was the International Year of Air and Space'' and ''International Space School Sputnik Program.'' The French and Russian messages convey the same greetings. Sputnik 41 is the same size as Sputnik 40--just under 8 inches in diameter and weighing almost 9 pounds. It carries a 200 mW transmitter that transmits on or about 145.812 MHz (+/- 5 kHz and Doppler shift). The spacecraft has no solar cells. Its expected operational lifetime is approximately 30 days. The new spacecraft also has a beacon. The frequency of the audio tone indicates the satellite's internal temperature. The tone is transmitted every 90 seconds. Sputnik 41 reception reports go to AMSAT-France, QSL Spoutnik 41, 14 bis rue des Gourlis, F-92500 Rueil-Malmaison, FRANCE.
