ARLS004 Ham radio on STS-76

Mission managers at the NASA Kennedy Space Center have announced
March 21 as the official launch date for the Space Shuttle Atlantis,
and mission STS-76. The mission marks the third time the shuttle
will dock with the Russian Mir Space Station. The astronauts are
also planning to conduct Amateur Radio activities as part of the
Shuttle Amateur Radio EXperiment (SAREX). Five student groups have
been selected to make scheduled radio contacts with the crew.

The shuttle will also carry a SPACEHAB laboratory, providing the
astronauts with a working environment to conduct microgravity
research and development, and to help resupply Mir.

The astronauts may find time to make contacts with the amateur
community and their own families. All of the contacts will be
2-meter FM voice, using the shuttle's VHF Mir-docking radio.
Frequencies, call signs and general operating information can be
obtained from the new ARRL SAREX World Wide Web site at

The following pre-launch Keplerian elements can be used by most
computer tracking software to predict the ground track of the
shuttle. The elements are based on a scheduled launch of March 21 at
0835 UTC. Thanks to Ken Ernandes, N2WWD, for the following elements
which were found on the AMSAT Web site at
