SpaceNews originates at KD2BD in Wall Township, New Jersey, USA.  It
is published every week and is made available for non-commercial use.

NASA's Mars Pathfinder landed safely on the surface of Mars on 04-Jul-97.
Within hours of its landing, the first images of the Martian landscape
were taken by Pathfinder and relayed to Earth.  Several minor problems
affecting Pathfinder's computer and the communications link between
the Sojourner rover were ironed out, and Sojourner was allowed to roll
out to the Martian surface on 06-Jul-97, marking the first time a motor
vehicle of earth origin has made contact with the surface of another

Pathfinder images and news are available via a host of World Wide Web
sites on the Internet, including:

We have now got the base block, the module Kvant 2 back on line, leaving
2 more modules.  Working very hard, lights in our mouths, in the dark,
moving batteries about, to enable better charging, with solar arrays.
O2 electrolysis  soon, in old Kvant.  Much interest from control center
to do internal eva to reconnect power to lost Spkektr module, to receive
its substantial electrical power from its large arrays.

Thanks for all your good wishes.  Mike.

 We are still in low power status, only one module and base
 block are powered presently.  Crew preparing to do eva inside
 node, to open hatch of spektr module, and replace with hatch
 with special passthrus, to allow power from speon.  Date tbd,
 but after 11th July.  Progress docking planned for 8th.  Mike. kb5uac.

* MSL-1 NEWS *
The Microgravity Sciences Laboratory (MSL-1) mission is well underway
aboard Space Shuttle Columbia.  MSL-1 includes experiments that may
affect health care (protein crystal growth), the metals industry
(metallurgy experiments), transportation (combustion physics), and
other areas of the economy.

Several Internet URLs of interest dealing with MSL-1 include two at
NASA's Marshall Space Flight Center:

Fernando, LU1HKO reports reception of DOVE's S-Band beacon over Cordoba,
Argentina on 03-Jul-97.  Fernando reports the S-Band beacon was weak and
unmodulated.  Nothing was heard on the 2-meter beacon.

The SAREX experiment has been activated on Space Shuttle Columbia and many
two-way voice contacts have been reported, including scheduled contacts
with school children.  Those wishing to contact the Shuttle are reminded
that the SAREX package on STS-94 is completely battery powered, the crew
is quite busy with experiments, and packet radio operation isn't expected
until possibly towards the end of the 16-day mission.
