* SCHOOL CONTACT WITH MIR *
===========================
A radio contact between the Nashua (New Hampshire) High School and the
cosmonauts on the Russian space station Mir took place on Tuesday 17-Jan-95.
The contact went very well, and Nashua High School enjoyed a horizon to
horizon contact with Exeter High School joining in at the very end.
 
Miles (WF1F) took his equipment up to supplement the Nashua High station
and Cosmonaut Valery answered 14-16 Questions from students.  Dave, N1PPP,
monitored the contact from his home in Claremont, N.H. and was able to
clearly hear nearly everything that was said by Valery.
 
Dave, N6JLH uploaded the questions to Mir beforehand, after Dave made the
initial contact with Valery.
 
N1PPP would like to thank all who helped make the contact possible,
especially N6JLH and WF1F.  As Dave, N1PPP puts it, "It is always a lot of
work, but very worthwhile when it ends with a good contact with a school".

* ITAMSAT NEWS *
================
Spacecraft status as of 24-Jan-95:
 
After two months of unattended operation under IHT ver 2.0 control, ITAMSAT
(IO-26) is sending telemetry and WOD dumps in good health.  Signals are
reported to be strong and easy to decode.  I2KBD has passed to the ground
controllers the final version of the IHT ver 3.0 with auto scheduling
capabilities, that will enable auto shut-off of the trasmitter during
scheduled time, to save battery and allow higher power operations when
the BBS is running.
 
Upload of the new IHT was expected to start last week, followed by WOD
dumps to evaluate the power saving.  If all goes fine, BBS operations is
expected by the first ten days of February.  A World Wide Web (WWW) page
on ITAMSAT and AMSAT member from Italy, is expected to start soon, more
news ASAP!

* WATCH FOR MIR & STS-67! *
===========================
The STS-63 Space Shuttle mission is scheduled to be launched at 02-Feb-95
at 05:50:44 UTC.  This mission will rendezvous with Mir on the fourth day
of the mission, but will not dock.
 
Mir will be visible in the morning sky over much of the US during this
flight.  Since MIR and the shuttles are individually large and bright,
the two of them flying in formation should be a beautiful sight!
 
Normally the shuttle's exact path is not known until after it has been
launched.  However, Mir's orbit is well established and should remain
stable from now until the end of the STS-63 mission.  Since the shuttle
will fly to Mir, the orbital track of Mir will be a close approximation
of that of the Shuttle.
 
It is suggested than anyone who is interested in watching Mir and the
Space Shuttle start keeping tabs on Mir now by looking for good passes
for your area.  You'll need a tracking program that can check for VISIBLE
passes.  For a satellite to be visible, it must be above your horizon and
in sunlight while you are in darkness on the ground.
 
One tip: most satellites are so faint that they aren't visible unless the
sun is at least ten or twelve degrees below the horizon.  Mir and the
shuttle, however, are both very bright, so you should set your tracking
program to look for passes where the sun is at least 4 degrees below the
horizon.  The sky can be so bright you can read a newspaper and you'll
still be able to see either of these spacecraft.
 
If you spot any good passes, please be sure to tell others where and when
to look.  And don't forget to monitor 145.55 for ham activity from either
spacecraft!
 
The following are the preliminary Keplerian elements for STS-67:
 
Satellite: STS-67
Catalog number: 00067
Epoch time:      95061.32643015   =    (02-MAR-95   07:50:03.56 UTC)
Element set:     004

Arg of perigee:   287.7960 deg           Launch:  02-MAR-95  06:37 UTC
Mean anomaly:      72.2100 deg

* RS-15 KEP UPDATE *
====================
The latest Keps for RS-15 (Element set #21) from NASA OIG RAID RBBS agree
VERY WELL with estimated elements (N2WWD set #5).  The official NASA
elements for RS-15 as computed by Space Command are:
 
RS-15       
1 23439U 94085A   95018.43232054 -.00000039  00000-0  10000-3 0   216
2 23439  64.8172 137.1826 0167589 287.8288  70.4424 11.27524601  2639
 
The equivalent elements in AMSAT format are:
 
Satellite: RS-15
Catalog number: 23439
Epoch time:      95018.43232054
Element set:       21
Inclination:       64.8172 deg
RA of node:       137.1826 deg
Eccentricity:    0.0167589
Arg of perigee:   287.8288 deg
Mean anomaly:      70.4424 deg
Mean motion:   11.27524601 rev/day
Decay rate:      -3.90e-07 rev/day^2
Epoch rev:             263
 
The comparison of the above elements against N2WWD set 5 yields the 
following differences:
 
Differences for Epoch Update of 23.17 days:
                                          
In-Plane  Phasing:     0.003383 rev = 25.9 sec
Plane  Difference:     0.021314 deg
Height Difference:     3.790436 km
Period Difference:     0.000015 rev = 0.115 sec
 
Ken, N2WWD wishes to thank Space Command for their attention to the problem
and their efforts in identifying the RS-15 spacecraft from the other pieces
in the debris cloud.  With this news, Ken is retiring N2WWD estimated
element set #5 for RS-15.

* NEWS CORRECTIONS *
====================
Ted Cline, N0RQV, reports the full WWW address (URL) for the "AMSAT Home
Page" reported in last week's issue of SpaceNews is:
 
        http://www.amsat.org/amsat/AmsatHome.html
 
Steve, WD8QCN, found NOAA-14 transmitting HRPT data on 1698.0 MHz.  This
was true for the first few passes that he observed, however it seems to
have been switched to 1707 MHz a few weeks ago.  Steve tracked several
passes on 12-13-Jan where the only transmissions heard were on 1707 MHz.
Steve feels it is unlikely that he locked onto another bird, since NOAA-14
shows up much earlier than the other NOAAs right now, and his antenna has
a beamwidth of 0.75 degrees at L-Band.
