Mir ARS Status March 8, 1999, Random Radio

Mir Amateur Radio Status:  March 8, 1998

by Miles Mann WF1F,
MAREX-NA (Manned Amateur Radio Experiment, North American Division)

Mir's Random Radio Schedule:

One thing we learned a long time ago, is the Mir crews have the right to
change their plans
when ever they need to make adjustments.  This means, that the crew can and
will shutdown
the Amateur Radio equipment when ever there is a need to do so.  Or the
crew will change the radio schedules to suite their needs.

This past weekend is a good example.
On Friday, there was No Amateur radio activity (Friday is usually a Packet
On Saturday, there was some SSTV activity
And on Sunday, Packet and SSTV were both turned off and Jean-Pierre was
active on Voice.
Does this mean there is a Problem?  Not at All.
Part of the reason Packet was turned off, was because French cosmonaut
Jean-Pierre Heignere
had some free time and he wanted to talk on Voice.  He turned off the
packet PMS, so he could
hear people better.

Common reasons for Shutting down the Amateur Radio equipment on Mir.
1.   Docking Missions:  Whenever there is a docking or undocking taking
place, the orders are to turn off all unnecessary radio equipment.
2.   Electrical maintenance:  Routine maintenance requires that power is
sometimes shutdown while the crew is working on the electrical system.
3.   Power conservation:  Some experiments require huge amounts of power
(crystal ovens)
4.   Eclipse:  During periods of long eclipse, it is sometimes necessary to
conserve power.
5.   Navigation computer problems:  in 1997 a worn-out navigation computer
forced several emergency power shutdowns.  The computer has been replace
and working great for the past 2 years.

Amateur Radio equipment shutdowns are command and there is no reason to
worry if you do not hear your favorite satellite for a few days.

New Mir Crew Members:
The current crew consists of:

Current Crew
SOYUZ TM-29 arrived at Mir on February 20, 1999.  Mir Soyuz TM-29 crew
consisted of French cosmonaut Jean-Pierre Heignere, Viktor Afanasyev  and
Slovakian Cosmonaut Ivan Bella
On February 28, some of the crew returned to earth, they were:
Slovak Ivan Bella and Gennadiy Paldalko.
Gennadiys mission lasted approximately 6 months (August 16 1998 – February
28 1999)

The remaining crew consists of:

The French cosmonaut Jean-Pierre Heignere
Cosmonaut Viktor Afanasyev
Cosmonaut Sergei Avdeyev.  Sergei mission began August 16, and is expected
to last a total of 9-11 months.

This will make the Mir crew 27 a three man crew. Energia informed me that
the French Cosmonaut Jean-Pierre did receive training on the MAREX-NA SSTV
project, and he has already sent a few SSTV images of him self and the rest
of the Mir crew.

Current Schedule for Packet PMS and SSTV:
The SSTV system was active Saturday March 6 and Monday March 8.

The crew will do their best to keep the SSTV system active on weekends and
packet PMS operational on weekdays.

Equipment Pictures:
I am looking for Pictures of the Amateur Radio equipment currently on the
Russian Space Station Mir.
I have searched a few of the NASA archives, with limited luck.  Most of the
equipment shots I have received from other sources.  This week I received a
nice shot from Tony VK5ZAI.  The picture shows Astronaut Andy Thomas
talking on the 2-meter station from the Pirioda module on Mir.  In the back
ground you can see good shot of the MAREX-NA DCI filter.  The filter was
needed to keep the Mir 143 MHz commercial radio from De-sensing the 2-meter

Current inventory list of amateur radio hardware on Mir:
SUFAX II Repeater (Icom)
Kenwood TM-733 (for PMS)
Kenwood TM-V7A (for SSTV)
Packcom TNC (old PMS modem)
Kantronics KPC-9612 (current PMS modem)

If you do find a good shots taken from Mir of the Amateur radio hardware,
please send the JPG or GIF to my E-mail address. The best pictures will be
posted to the MAREX-NA web page.

Tracking Mir

The best way to track satellites is to get access to a good satellite
tracking program.
There are numerous programs on the market, both for sale and share ware.

The best place for current satellite position date (Kep’) data is at the
CelesTrak web page http://celestrak.com/
