1.(N) Shuttle Motor Test Now Called "Major Failure"
Reversing earlier preliminary announcements, a NASA spokesman has acknowledged
the December 23 ground test of a Shuttle rocket booster (SRB) engine did not
go well at all. Preliminary reports of the full scale, horizontal test at
Morton Thiokol's Wasatch Test Range in Utah had declared the results a
complete success. An announcement by NASA December 29 overturned the earlier
optimistic report and has once again cast a gloomy pall over prospects for a
1988 resumption of shuttle launches.
The later announcement of the stunning failure was made when closer examination
of the test article revealed extensive damage to the nozzle area. The failure
of a new rubber-like ring, a part of the rocket motor nozzle mechanism,
presented Morton Thiokol, the manufacturer, with another major setback in its
SRB recovery efforts. A large portion of the nozzle's outer boot ring was
missing. Nearly four feet of the eight foot diameter ring had vanished NASA
said.
It was a fault with an SRB field joint O-ring design that has been blamed for
the calamity which struck the shuttle Challenger nearly two years ago claiming
the lives of seven astronauts and beginning an incredible series of launcher
failures which virtually halted U.S. access to space. Morton Thiokol has
since re-designed the O-rings. The test December 23 was one of a series
scheduled to prove out the new O-ring design and to expand the test envelope
to provide higher levels of confidence in the overall design.
NASA indicates the launch of the shuttle Discovery, which had been planned for
June, 1988 will definitely be delayed. How long the delay will be depends on
whom one speaks with. Some persons indicated the delay could be days or
weeks. Others suggested months of delays are in the offing. The most
pessimistic view expressed suggested that if nozzle re-design were required,
it would be impossible to resume Shuttle launches in 1988. It will be a few
weeks before a full damage and delay assessment can be made NASA said.
Obviously, all SAREX (Shuttle Amateur Radio Experiments) are on hold pending
resumption of shuttle operations. Tony England, W0ORE and Ron Parise, WA4SIR,
are the only currently licensed amateurs in the Astronaut corps. Tony has
flown before while Ron has not. Both have plans for SAREX operations during
their future flights. Tony's future missions will again emphasize video
exchanges in an educational setting while Ron's activities will emphasize
packet radio exchanges. Neither appears likely in 1988, however.

2.(N) Soyuz Module Successfully Recovered In Kazakstan
The Soviet Union capped another major space mission with the safe return to
earth December 29 of three Cosmonauts including Yuri Romanencko who set a
space endurance record of 326 consecutive days in space. He was accompanied
by Alexander Alexandrov and Anatoly Levchencko in the safe landing in the
Soviet province of Kazakstan in the Steppes. The crew was flown by helicopter
to the Baikonur Cosmodrome at Tyuratam where they were received by space
officials, family, dignitaries and other well-wishers.
Romanencko appeared alert but weak as he disembarked from the Soyuz module
upon landing. He was carried by stretcher to the waiting helicopter. The
landing was broadcast live on Soviet television. By the time the helicopter
reached the Cosmodrome, however, Romanencko was fit enough to walk unaided
having regained the use of his faculties in the gravity environment he hadn't
felt in very nearly 11 months.
The Soviets have said the crew launched December 21, which relieved Romanencko
and Alexandrov, will stay aloft as long as one year to study the effects of
prolonged weightlessness as a prelude to a planned three year long flight to
Mars in the next decade. The crew on Mir now consists of Mission Commander
and space veteran Vladimir Titov and Pilot/Engineer Musa Manarov.
Since his launch to orbit last January, Romanencko circled the earth more than
5200 times covering nearly 130,000,000 miles at an altitude of 210 miles above
earth. In the past, Cosmonauts have been heard on the VHF band at 143.625 MHz
making them easily observev on many receivers.

3.(N) AO-10 Operating Conditions Good As Many Return During Holidays
AO-10 use is picking up again as many have used the year-end holiday period to
become reacquainted with the veteran satellite. Mode B operations have been
good to excellent thanks in part to the operating schedule which allows
operation at and near to perigee. The reduced path losses which result from
operating near perigee more than compensate for the use of the omni antennas
on the satellite. The omni antennas have been switched on line since the last
power restoral a couple of months ago.
Stations monitored during the holiday period seemed to have no difficulty
using Mode B with modest power levels and comments were generally favorable
concerning the QSO-quality. AO-10's apogee is now approaching its most
northerly extent near 27 degrees North latitude. This means that northern
stations have their best shot ever at over-the-pole DX and they should take
advantage of the opportunity to work into the Indian Ocean area while they
can.

4.(N) Short Bursts
The launch of AMSAT's Phase 3C satellite is just about 90 days away now
according to the best available estimates. As the countdown proceeds to
launch, AMSAT planners are lining up a major effort to bring the live launch
countdown to the four corners of the world via its ALINS, the AMSAT Launch
Information Network. Under the leadership of Operations Vice President Ralph
Wallio, W0RPK, the Phase 3C ALINS will provide extensive pre-launch, launch
countdown and post-launch coverage on a world-wide radio and telephone hookup.
Watch for details in an upcoming AMSAT News Service bulletin.

5.(U) AO-10 Ops Schedule
Here is the AO-10 operating schedule for the next two months:
AMSAT OSCAR 10 Transponder Operating Schedule
=============================================
Revised 26Dec87
Time Frame Mode B Operating Times in MA
Dec 29 thru Jan 03 0 thru 139 and 221 thru 255
Jan 04 thru Jan 17 0 thru 159 and 221 thru 255
Jan 18 thru Jan 31 0 thru 169 and 231 thru 255
Feb 01 thru Feb 14 0 thru 179 and 241 thru 255
Feb 15 thru Feb 28 0 thru 189
At the end of February, the sun angle will again go below 50% requiring
suspension of operations for a couple of months.
The current attitude of AO-10 has been estimated by G3RUH to be approximately
112 and -10 degrees in the Bahn coordinate system. In computer programs
requiring this input, enter 112 for Bahn Longitude and -10 for Bahn Latitude.
Some programs do not require this input.
As always, please insure you use the lowest uplink power levels so as to
insure satellite health as well as good communications.
