Jumpseat has been known for about the last 10 years (see e.g. books
of Jeff Richelson, Des Ball, Duncan Campbell & Seymour Hersh). Hasn't
been mentioned much in AW&ST though (if at all).

Well for most of 70's anyway, after that it was known that the Jumpseat
programme existed, just hard (or impossible) to distinguish individual launches.

As well as its role in air ground communication, and in linking US
ground stations, and (possibly) in IR detection of SLBM launches
from polar regions (which are at a very oblique angle as viewed by DSP
satellites in Clarke orbit). Latter may be a Jumpseat role instead.

Wouldn't TDRSS be better suited; how good is DSCS 3 at tracking (fast) moving
targets ?? TDRSS is certainly reported to be used sometimes for
Lacrosse, why not KH-11 et al.

# SOAP BOX ON

Okay then, why are we (the public) hearing that Voyagers are just receiving:
"Routine Science Data"!
If there is still interest in specific objects or areas, why don't we know
what's being looked at?  What bothers me the most is that once the fanfair
of a big encounter is over everybody forgets about the whole project.
Engineers stop talking, and Reporters stop reporting.  Yes many people
lose interest after "the big event", but a lot of us don't.  It seems like
a waste of good "PR" for NASA to stop talking.

# SOAP BOX OFF

FFFFEW! I feel better now.
Go Lakers Ron?

I recall reading a book by Jacques Cousteau describing his experiences
with the newly invented SCUBA-gear. He once went down to about 30
meters' depth with pure oxygen tubes, at which point he fainted. I
don't recall exactly why this happened. In any event, he decided
(wisely :-) to rely on mixed-gas tubes in latter dives.

                  Voyager Mission Status Report
                         May 16, 1990

                           Voyager 1

     The Voyager 1 spacecraft continues to collect routine cruise science data.
On May 4 a six hour Ultraviolet Spectrometer (UVS) observation of HD 217675 was
executed; there was no Deep Space Network (DSN) 70 meter antenna support
available therefore the downlink of this observation was not received. On
May 7 a frame of Plasma Wave (PWS) data was recorded for future playback.

     A Digital Tape Recorder (DTR) Tape Position (TAPPOS) slew was executed
in the low rate for the first time on May 8.  The tape position arrived at
was as expected however, a speed reduction of 2% was observed from the nominal
7.2 kbps slew rate.  This is a known idiosyncrasy of the DTR when operating
without the 7.2 kbps reference signal normally provided by the Flight Data
Subsystem (FDS).  This reference signal is not provided when the DTR is in
the Slew mode or when operating a non-record or playback data mode.

     Also on May 8 Playback #2, containing spacecraft roll maneuver (MAGROL)
data, was executed using the Plasma Wave Subsystem Data Playback (PWSPB) Block
Routine (BR9).  This was the first execution of this block and the spacecraft
performance was nominal.  There was however, a maximum of -0.5 db downlink
degradation introduced into the DSS 63/65 array (70 meter and 34 meter
antennas in Spain arrayed together) due to a problem with the DSS 63
sub-reflector being fixed at the 35 degree position.  The data quality appeared
to be acceptable for the playback.


                           Voyager 2

     The Voyager 2 spacecraft also continues to collect routine cruise science
data.  On May 7 and May 10 eleven hour UVS observations of Markarian 509 were
executed by the spacecraft; there was no 70 meter DSN support available for
either observation therefore downlink of this data was not received.  On
May 8 a frame of PWS data was recorded for future playback.

     A Plasma instrument calibration (PLSCAL) was executed by the spacecraft
on May 9.  Performance of the calibration was nominal and no problems were
experienced.

     The memory compare process has been completed on data received from
the FDS memory read-out performed on April 25.  The compare indicates
that the FDS memory contents are as expected.

     Spacecraft performance for all of the sequenced activity during this
report period has been nominal.

I seem to remember from somewhere (in First Aid Training I think) that
breathing pure O2 is not only dangerous, but can be lethal.  When divers
exceed the 'normal' dive limits they are breathing a mixture of helium and
oxygen...is it possible the EVA guys do the same thing?  I realize that the
pressure problem is reversed, but even still pure O2?  Anyone out there work
with the systems involved who can definitively answer this question?

Thanks,

I called the number above and verified that this is the address for
space camp inquiries, but you may want to call first.  This is a nice
place to visit, even if you can't get enrolled in space camp.

If you do visit, drop me a line while you're in town.  The first cup

Not documented (obviously), and not likely either.  The married
couples who are astronauts do not fly together.  At least one pair
was rejected for a flight together because they are "too frisky",
according to a friend of mine.

According to a recent _Analog_ article, some rather clandestine
experiments have been done in the WET-F (underwater zero-G simulator
facility).  (Wonder why any swimming pool won't do?  That part did
make me a bit suspicious...)  The conclusion is that having a third
party to help push in the right direction now and then is helpful,
just like dolphins.  The author of the article suggested the "Three
Dolphin Club" (like the Mile High Club) for those who manage it.
