Subject: a query about spacecraft velocity measurement
Newsgroups: comp.robotics,sci.space

Hi,

    I have a question about velocity measurement in spacecrafts and ALVs.
Do techniques exist to accurately measure velocity (speed and direction) of
a spacecraft/ALV, using inertial or other means? Of particular interest is
measurement of "slow" relative velocities at times such as docking and during
ALV exploratory activities.

    Please send replies to [e-mail].

Thanks,

Spacecraft generally use radar to assist in rendezvous and docking.
A reasonably thorough review of the current state of such radars is
presented in

J.W. Locke and L.J. Cantafio, "Rendezvous Radar," in Space-based Radar
Handbook, L.J. Cantafi, Ed. Norwood, MA: Artech House, 1989, pp. 197-227.

Much of their discussion is based on the rendezvous radar used by the
Shuttle (the Integrated Radar and Communications Subsystem) and the
radar for the proposed Orbital Maneuvering Vehicle (OMV).  There are
other books and publications that deal with such matters but this is
a good one to start with.

For general interest, the following is a summary of the track performance
of the IRACS radar used aboard the shuttle:

           Angle accuracy (3 sigma)      8 mrad
           Angle Rate     (3 sigma)      0.14 mrad/s
           Range Accuracy (3 sigma)      80 ft,         R <  1.3 nmi;
                                         1% of R, 1.3 < R <  4.9 nmi;
                                         300 ft,  4.9 < R < 12 nmi.
      Range Rate Accuracy (3 sigma)      1 ft/s,        R < 10 nmi

Hope this helps.

Not sure where they are built, but I do believe they operate from
either Hangar 18 or the Area 51 base in Nevada (Dreamland)

I think some are also based at Tonopah(sp?)

This sounds very good. Probabilities are definitely in favor of Aurora.
However:
1) There is no final proof. In particular, the few visual observations
reported in AW&ST are dubious and inconclusive.
2) There is at least one inconsistency: if Aurora were that excellent,
why does it need to fly at rather low altitude and supersonic speed
over the Los Angeles area? "Airquakes" seem not pleasant. Common sense
suggests that Aurora has some major flaw or drawback, otherwise it
would avoid these airquakes.
3) There are pending questions: had the sonic booms over the East Coast
in 1977-1978 something to do with Aurora? More likely, was Aurora the
cause of the boom over the Netherlands on August 19, 1992?

Subject: Color-Pictures from Voyager?
Newsgroups: sci.astro,sci.space

Hi.

I downloaded some pictures of the Voyager-CD-ROMs.
They're greyscaled, but they've been shot with different colorfilters,
so one can paste several greyscale pictures to one color-image.
But *how* can I restore the real colors (in RGB-format)?

For example, if I've got pictures with violet, green and blue filter,
is it correct
to set red  =violet
       green=green
       blue =(violet+blue)/2  or something?
Who can help?

And the other problem:
Different pictures were shot at different times, so the objects have moved.
How can I place several pictures on the screen so that the (moved) objects
match each other?

Please respond via E-Mail, if possible, because I can't reads the newsgroups
for the next two weeks.

Subject: FLOX and methane
Newsgroups: sci.space

I finally got around to reading Jim Oberg's "Mission to Mars" this
weekend.  On page 46, he mentions that in a definitive 1967 Mars mission
study headed by G.S. Canetti of North American Rockwell, the ascent system
of the proposed Mars Excursion Module (MEM)

   was powered by a combination of FLOX (fluorine and liquid oxygen)
   and methane, two propellants chosen for their safe storability
   over nearly a year in space before engine firing.

I would have thought some sort of non-cryogenic/hypergolic propellant
would have been preferable.  Can anyone shed light on what I'm missing?

To detect a doppler shift in gravitons, you would have to be able to detect
gravitons in the first place, and we have not been able to so far. That's like
trying to listen for the doppler shift in a train's whistle as it's approaching
you when you are deaf anyway.

But ignoring that, it sounds like the events you could detect would be
things like massive objects speeding toward or away from you. But according
to many articles on the subject, some of the things that would produce
gravity waves are neutron stars orbiting black holes, or super novae. These
don't have as much doppler shift as other things such as quasars, which have
huge red-shifts, or even galaxies as they spin.

If a gravity wave travels between the spacecraft, and the receiver on the
Earth, it will curve space and increase the distance between us and the
spacecraft. If they time the pulses from the ground to the spacecraft,
and back to Earth they should see a slight increase in distance between the
spacecraft, and the Earth (accounting for the spacecraft's velocity of course).
And they will have to  accurately account for the time it takes the spacecraft
to proccess the signal, and send it back. If it takes a constant amount of time
to do this, then you can just ignore it.

According to: Grjotheim & Welsh : Aluminium smelter technology
              Aluminium-Verlag 1988 (Dusseldorf)

Historically, the first time Al is mentioned is in 'Historia Naturalis'
published in the first century by the roman author Gaius Plinius.  It is
here told of a metal which was extracted from 'plain clay' by a goldsmith
from the city of Rome.  The emperor did not like the fact that this man was
not willing to give the secret of making this metal to anybody else, so he
cut his head of..... (sic!)

Al hides itself again in its strong bondings withother compounds (esp.
Oxygen) until 1825 when Oersted extracted a few milligrams of it from AlCl4
with potassium amalgam in a thermal reduction process.  Aluminium cannot be
produced by carbothermic reduction as more noble metals can for obvious
reasons.....

It is not until 1854 that a handelable amount is produced, this time by a
french schoolteacher St.Claire-Deville.  The french emperor Napoleon III
gives this man fundings for producing Al for use as armour for his
soldiers.  The material is still very expensive and only a few Helmets, the
famous dinner set and some toys were produced.

Does anyone out there have a Thrust History for the Super Loki sounding rocket.
This is a combination of the Dart payload vehicle and the Microstar II booster.

Subject: UARS Status?

Is there anyone who can bring me up to date on
the status of the Upper Atmosphere Research Satellite?

I understand that it is providing great (!!) science.
Is this still true?

What sort of results have been obtained from the Satellite's
Instruments?  Occasionally one hears results about JPL's MLS,
but there are 9 other instruments!

For all Instruments (I believe, although ACRIM may have been
a separate case) the Science Data Processing Production Software
was supposed to produce results in reasonable time.  Has that
indeed taken place?

Is there any word on how the British Instrument (ISAMS) faired
with some of the difficulties they had?

And finally, is there any truth to the rumours about some
difficulties with the satellite's batteries?

        In reply to my suggestion that pentane be used as a low-viscocity
fluid in neutral buoyancy simulators:

        I'm not suggesting that the support/rescue team be on SCUBA - they
would have to be in a full suit something similar to what the astronaut test
subject is wearing.  The number of people submerged is also likely to be
considerably less, with the most faithful simulation involving just the
astronaut(s) involved in the maneuver being practiced (after all, they are
practicing for conditions in space where there will be no support team
available to help them recover from fumbles).

        Pentane is very easily evaporated, and there is no need for people to
come in contact with it.  An astronaut coming out of the simulator tank would
only need perhaps a minute of "blow-drying" with nitrogen to free his/her
suit of external pentane.

Subject: Weekly reminder for Frequently Asked Questions list
Newsgroups: sci.space,sci.astro,sci.space.shuttle

    This notice will be posted weekly in sci.space, sci.astro, and
sci.space.shuttle.

    The Frequently Asked Questions (FAQ) list for sci.space and sci.astro is
posted approximately monthly. It also covers many questions that come up on
sci.space.shuttle (for shuttle launch dates, see below).

    The FAQ is posted with a long expiration date, so a copy may be in your
news spool directory (look at old articles in sci.space). If not, here are
two ways to get a copy without waiting for the next posting:

    (1) If your machine is on the Internet, it can be obtained by anonymous
FTP from the SPACE archive at ames.arc.nasa.gov (128.102.18.3) in directory
pub/SPACE/FAQ.

    (2) Otherwise, send email to '[e-mail]'
containing the single line:

help

    The archive server will return directions on how to use it. To get an
index of files in the FAQ directory, send email containing the lines:

send space FAQ/Index
send space FAQ/faq1

    Use these files as a guide to which other files to retrieve to answer
your questions.

    Shuttle launch dates are posted by Ken Hollis periodically in
sci.space.shuttle. A copy of his manifest is now available in the Ames
archive in pub/SPACE/FAQ/manifest and may be requested from the email
archive-server with 'send space FAQ/manifest'. Please get this document
instead of posting requests for information on launches and landings.

    Do not post followups to this article; respond to the author.

Press Release Nr.14-93
Paris, 22 March 1993

Wubbo J. Ockels appointed Professor

The ESA astronaut Dr Wubbo J. Ockels, has been appointed
to the ESTEC Professorial Chair in the faculty of Aerospace
Engineering at the Technical University, Delft. This University
is the only Dutch University with a separate faculty in
aerospace engineering.

Dr. Ockels will be the second occupant of a Chair created
some years ago to emphasise and strengthen the long-standing
and close ties that have existed since the setting up of ESA's
Space Research and Technology Centre (ESTEC) in the
Netherlands, and the Technical University.

This fits in well with the philosophy and policy of ESA which
seeks to assist young European engineers who wish to
specialise in aerospace related disciplines, and to help them
prepare for their future role in space industry and space
research centres of the ESA Member States.

Dr. Wubbo Ockels was a payload specialist on the highly
successful Spacelab D-1 mission in 1985, and is presently
active in preparations for European manned space flight
activities.

Dr. Ockels will make his inaugural address on 24 March in
the central auditorium of the Technical University, Delft. His
main theme will be "the Vertical Challenge", including cross
fertilisation between aeronautical and space technology
disciplines, as well as the general "vertical challenge" facing
humans at the present time.

Dr. Ockels sees his new duties, which will include weekly
lectures and tutorials, as being a significant challenge to
stimulate the coming generations of technical specialists to
seek careers in the European aerospace community.
