>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.  The 1998
