   'Man-tended' : Every once in a while when the shuttle goes up,
                  stop by to turn things on and off, install an experiment
                  or two, collect samples, and fix things.

   'Manned'     : Drop folks off and leave them there for a while now and

                  be there to take care of things. [Mir is 'manned']

   'Perm Manned': Keep someone there all the time to take care of things.

                       MONDAY OCTOBER 29, 1990

SpaceNews originates at KD2BD in Wall Township, New Jersey, United States.
It is published every week and is made available for unlimited distribution.



* DOVE NEWS *
=============
The following message from N4HY was recently carried on DOVE-1/OSCAR-17:

DOVE-1>BRAMST <UI>:
The new file system will be loaded to PACSAT and BBS operations will commence
in the next couple of days.  Upon testing file system there, DOVE will be
reloaded.  This will occur next week.  73 de BM  Oct. 18


* PACSAT NEWS *
===============
The MicroSAT BBS has been tested on the ground engineering unit, and is now
ready for uploading to AO-16.  The satellite BBS software was written by Jeff
Ward, G0/K8KA, at UoSAT and was ported to the microsats by NK6K.  The porting
was easily achieved, as there are only 10 lines of code that are different
between the UoSAT version and the Microsat version.  A lot of effort went into
the design of the BBS, operating system, and other support code to make that
possible.  Once complete, the following elements will be available:

256k file system:

This is just half of one of the four available banks of bank switched memory.
The more complete file system using all four banks and the 6MB mass memory
will be uploaded after more testing.

FTL0 file server:

This implements the protocol described in the FTL0 document, available on CIS,
the 9th ARRL Networking Conference proceedings, and elsewhere. It allows file
uploading, downloading, and a simple directory display.  It requires the use
of software at the groundstation: a simple version, called "PG" has been
written by Jeff and will be on CIS soon.

Broadcast server:

This implements the broadcast protocol as described along with FTL0 and has
been running for several weeks on UO-14, and a few people have rolled their
own receive program, at least one written in BASIC.  A simple version, called
"KISSUI" has been written by Jeff and will be on CIS soon.

After this is loaded, the following separate programs will be running on
AO-16:

Kernel - Operating system - NK6K/Quadron
AX25   - AX25 driver - NK6K/WB6YMH/Quadron, pd on a KA9Q AX25 implementation.
PHT    - Spacecraft control, power management & program loader - N4HY/NK6K
AARTD  - AART driver - NK6K/WB6YMH
MFILE  - File system - G0/K8KA/UoSAT
FTL0   - File upload/download - G0/K8KA/UoSAT
PBP    - File broadcaster - G0/K8KA/UoSAT

Mode-JL: MA 095 to 125
Mode-LS: MA 125 to 130
Mode-S : MA 130 to 135
Mode-BS: MA 135 to 140
Mode-B : MA 140 to 256
Omnis  : MA 220 to 040

This schedule is expected to continue throu 26-Dec-90.  The spacecraft
attitude is BLON = 180  and  BLAT = 0.

  This kind of reminds me of the "flag over the capitol" thing
 run (or used to be run) by the government.  It used to be that
 you could write your congressdroid and get a US flag that had
 flown over the capitol (or was it the white house? or both?).
 These got to be quite collectors items if they were in use
 on a notable day (trivia note... Nov 22, 1963? July 20, 1969...).
 However, demand got so great that eventually 3 flagpoles were
 installed adjacent to each other, and 3 people were employed to
 run flags up and down the poles (I think they let them fly for
 30 seconds or some such time) in 8 hour shifts...

Nope, the HST solar arrays are from British Aerospace, and the Galileo
thrusters are from MBB I think.

Actually, some of us make a living pointing radio telescopes at the Sun!
The reflector surfaces are painted white, and normally do not reflect enough
sunlight to do damage.  However, with our 27 meter diameter dishes at
Caltech's Owens Valley Radio Observatory, we found out the hard way what
happens when the dishes are shiny.  We burned up four feeds in about a
half hour one cold morning when the dishes were frosty.  The sunshine melted
the frost and made for pretty good specular reflection, costing us $8000
in repair bills.  We have a brightness sensor now, that automatically
scrams the dishes when over-bright.  I suppose the problem is more acute
with 70 meter diameter dishes.
