ARLS011 STS-83 postponed

NASA has postponed the launch of the space shuttle Columbia for 24
hours. Mission STS-83, which will carry the Shuttle Amateur Radio
EXperiment, SAREX, was due to be launched Thursday, April 3, 1997,
at 1901 UTC. Following a review on Wednesday, April 2, NASA managers
determined that a water coolant line in the orbiter's payload bay
will require additional insulation to prevent it from freezing
during the orbiter's 16 days in space.

Launch has been rescheduled for April 4 at 1901 UTC.

Three hams will be aboard the shuttle Columbia. They are James D.
Halsell, KC5RNI, mission commander, Janice E. Voss, KC5BTK, payload
commander, and Donald A. Thomas, KC5FVF, mission specialist. STS-83
is scheduled to last 16 days. The mission will carry SAREX
configuration C: voice and packet. The mission's primary payload is
the microgravity science laboratory.

Eighteen schools, including institutions in the People's Republic of
China and on Okinawa, have been scheduled for SAREX contacts during
the mission. The SAREX Working Group has designated the following
frequencies during the STS-83 mission:

  FM voice downlink (worldwide): 145.55 MHz
  FM voice uplink: 144.91, 144.93, 144.95, 144.97, and 144.99 MHz
  FM voice uplink (Europe only): 144.70, 144.75, and 144.80 MHz

If packet is available, the FM packet downlink will be 145.55 MHz;
