MONDAY JANUARY 25, 1999
SpaceNews originates at KD2BD in Wall Township, New Jersey, USA. It
is published every week and is made available for non-commercial use.
* MICROSAT BIRTHDAY *
Amateur Radio's first Microsat satellites celebrated their 9th birthday
on 1999-Jan-22. AMSAT-OSCAR-16, DOVE-OSCAR-17, WEBERSAT-OSCAR-18, and
LUSAT-OSCAR-19 were all launched together on 1990-Jan-22 from Kourou,
French Guiana. AMSAT-OSCAR-16 is the only satellite of the group that
continues to perform well. Functioning as a digital store-and-forward
communications satellite, AO-16 has been operating for over 1590 days
since its last on-board computer re-load. The remaining satellites
are not in full operation. DOVE-OSCAR-17 experienced a hardware
malfunction after launch that has made it nearly impossible for
controllers to upload operating software to the satellite.
WEBERSAT-OSCAR-18's primary function was to take digital color
images of the earth, but it also contains all the electronics necessary
to function as a store-and-forward digital communications transponder.
LUSAT-OSCAR-19 also contains a digital transponder, however it has
not been active since the satellite experienced an OBC software
crash last year.
* SUNSAT LAUNCH DELAYS *
Cliff Buttschardt, K7RR/W6HDO reports that the launch of SUNSAT has been
postponed for eight times. Most of the postponments were due to upper
air wind conditions that violated launch criteria despite the surperb
surface conditions at the launch site. Four South Africans have left
the US as a result of the launch delays, and only two remain for just
one more launch attempt. If this attempt is not successful, then SUNSAT
will have to be turned on from South Africa resulting in a much later
availability than the first few orbits.
The latest information is that the next attempt is postponed until Monday
night/Tuesday morning the 25th. Of course this may change but apparently
the Delta rocket will have to be defuelled at this time.
* TMSAT NEWS *
Chris Jackson, G7UPN, reports that the TMSAT OBC186 flight software crashed
on the afternoon of 1999-Jan-21. To in an effort to find the cause of the
crash, controllers performed a memory dump of the OBC186 computer program
memory late last week. OBC186 flight software was expected to be loaded
after the memory dump was complete.
* FUJI-OSCAR-29 NEWS *
FUJI-OSCAR-29 users have reported that the satellite has recently been
switched between analog and digital transponder mode. No official word
has been received from spacecraft controllers.

* LIFE EXTENSION FOR MIR *
Several news reports have indicated that the Russian space station Mir
may get a three year life extension if private investors can be found
to pay the expenses necessary to keep the spacecraft in operation.
Details are expected to be worked out in the next three months. It
costs an estimated $250 million a year to keep the Mir space station
