* DUHOP TESTS *
===============
UA3CR has arranged that the RS-14 (OSCAR-21) transponder will be switched
from the current FM digital 435.016/145.987 mhz mode to the RM-2 'B' mode
transponder from 2000 UTC on Tuesday 8th February for the Trans-Satellite
'DUHOP' tests to be conducted by G4CUO, G3CAG, G0NKA, G6HMS, G7MUB and any
other interested participators. RS-14 will be commanded back to #1 mode
again at 0350 UTC on Wednesday 9th February.
The experiment purpose is to investigate the possibility of long range
communication via two or more Amateur satellites, and the measurement of
Doppler shift between the spacecraft's travelling in opposite directions.
The frequencies to be used are as follows,
1. Ground station uplink to RS-14 via 435.105 mhz via CW or SSB (LSB).
2. Crosslink from RS-14 via space to RS-10 via 145.877 mhz +/- resulting
mutual approach Doppler shift on resulting CW or USB.
3. Downlink to ground station from RS-10 on 29.378 mhz +-Doppler CW/USB.
e.g from 70 cm to 10m via 2m mode 'B' to mode 'A'.
The call 'CQ DOHOP DE (call sign)' will be used on CW/SSB to indicate that
the trans-satellite TEST is in progress, and reports as 'DUHOP RS/T nn/n'.
A pass for Europe will commence at 2230 UTC on 8th February, Passes for
the UK and Europe with RS-14 and RS-10 in sight will occur from 0014 to
0017.5 UTC on 9th February, another from 0159 to 0201. The following pass
will be tried for UK and West Europe QSO attempts to W and VE, etc.
'Normal' (direct single satellite transponder users) are respectfully
asked to keep their powers low during the experimental periods, or better
still to participate in the experiment. SWL reports of RS-10's transponded
DUHOP transmissions will be appreciated by participating stations.

* TEXAS BALLOON LAUNCH NEWS *
=============================
NORTH TEXAS BALLOON PROJECT SECOND LAUNCH A SUCCESS (...FINALLY!)
The launch of the second mission of the North Texas Balloon
Project was a success on 6 February 1993 (after December and
January launch scrubs due to bad weather). Lift off was at 1509
UTC and landing occurred at 1655 UTC. The payload was recovered
less than an hour later just a few hundred yards from the shores
of Lake Whitney, only 32.5 miles south of the launch site.
Recovery time was excellent considering the payload actually
landed 30 miles away from the predicted landing point!
We would like to thank all of you who participated in the launch
by providing reception reports via the 40m launch net to Keith,
W5IU.
If you would like a QSL card for Mission #2, please send your
decoded telemetry and an SASE to Doug Howard - KG5OA, 2517
Coldstream Drive, Fort Worth, Texas 76123.
Our next launch will require only slight modification to the
payload and should be ready for launch in the next few months. So
stay tuned to this bulletin for more information on Mission #3!

* RUSSIAN SOLAR SAIL NEWS *
===========================
The Russian solar sail Znamya experiment ended on Sunday, February 7th
when the sail entered the atmosphere. Current reports indicate that
initial results went well after it was deployed from the Progress TM-15
cargo craft at the Mir space station about 4 am UTC (11 pm PST) Feb. 4th.
The solar sail illumined several areas in Europe, especially in Toulouse
France. Apparently in that southern French city, near the Spanish border,
the streets were noticeably brighter during the pass as seen by several town
people. Shortly after it crossed the day/night terminator in Europe the
solar sail was released from the Progress. Observations in Vancouver
suggested that it fell about 95 Km (60 mi) to about 300 km altitude in just
about 30 hours, by Friday (Feb. 5th) morning. Since such orbital decays would
increase rapidly so it would seem that by Feb. 6th it would have been down to
a 200 km orbit, and renter shortly there after on Feb. 7th as reported. This
is not unreasonable for a 20 metre (85 ft) diameter very light sail. Some
reports indicate that the Znamya was set free after the rotation which was to
stabilized its shape caused problems with the Progress' guidance. However,
note that the original experimental plan called for only about 3 days of
flight, consistent with this same time frame. Until more reports come out it
is not possible to tell which was the reason for the release. Dr. Leigh
Palmer observed the Mir space station on Feb. 7th, but the Progress was
no longer near it, so that has probably deorbited by now as well. That would
be consistent with standard operations. (Radio Moscow, BBC, CBC)
Certainly this ranks as one of the more noticed Russian/CIS space
experiments in recent years.
