| re: .0's trivia question
I haven't any idea, but here's my guess: Hughes.

| re:0
I dont know either but only because they seem to be very active
in publishing a satellite log I would say TRW but they may only
be a sub contractor
I can add a trivia question however
what is the oldest satellite still in orbit
|
296.3 | RE 296.2 | EDEN::KLAES | The Universe is safe. | Thu Jun 04 1987 10:18 | 8 |
| Vanguard II.
Now, what is the oldest satellite anywhere in space that is
still functioning? (I'm not sure about the answer, but I have a
good idea.)

| Ford Aerospace?
I worked for them on a satellite in the mid '60s. It was then
known as Philco WDL, AKA Philco-Ford. Think some of those birds
are still up there.

296.5 | And the answer is... | MONSTR::HUGHES | Gary Hughes | Thu Jun 04 1987 12:40 | 13 |
| Good guesses, but no cigar.
The answer is linked to the topic of the note. As of early 1986,
51% of all US satellites had been built by Lockheed, who also build
the Agena. They quietly build most of the USAF/CIA satellites. TRW
are tied in on a lot of them, but more in the operational side.
This is probably an extension of the 'watchman/byeman' security
concept where the person who knows the capabilities of the satellite
does not know the targets and vice versa.
If you eliminate military sats, my guess would also be Hughes.

| The oldest functioning satellite anywhere? Might that be Pioneer
n orbiting the sun?
And just a comment on the Agenas: They did not have a very good
record in the Gemini program as I recall. They (Atlas-Agena variant)
were used as rendezvous and docking targets for the Gemini spacecraft
(which were launched on Titans). As I recall, a number of tries
failed in various ways. Some failed to make orbit; some made orbit
but did not open up their docking port correctly (the famous
"clamshell"... this is of course not the fault of the Agena).
More trivia: When was the only time that the US has had two crewed,
separately-launched spacecraft in orbit at the same time, and how
does it relate to this topic?

| GEMINI 6 and 7 in 1965. GEMINI 6 was supposed to dock with
an AGENA target, but the AGENA was destroyed at launch. NASA decided
to go with a manned rondezvous instead.

296.8 | very old satellite | SAUTER::SAUTER | John Sauter | Thu Jun 04 1987 13:56 | 3 |
| The oldest satellite in Earth orbit is Luna. It's been there a
*very* long time.

296.9 | and the Envolope Please | IMGAWN::BIRO | | Fri Jun 05 1987 09:35 | 26 |
| ok some interesting ans to the oldest earth satellite
from Satellite Situation Report Nasa vol 27 no 1 march 31,1987
.3 with Vangauard 2 was close but
Vanguard 1 is still in orbit launch 17 Mar 1958
Vanguard 2 was not launch until 17 Feb 1959 about a year later
and it is still in orbit
as for the HELIOCENTRIC ORBITS
LUNA 1 launch on 2 JAN 1959 (USSR) is the oldest with
PIONEER 4 launch on 3 MAR 1959 (US) being next oldest and
the oldest US Heliocentric object
and one last point there are
1677 payload objects still in orbit
4999 debris object still in orbit
and 11187 object have decayed from orbit
and 24 countries/organization have at one time had payloads in space
anyone for a space junk yard

296.10 | Earlier than generally known... | EDEN::KLAES | The Universe is safe. | Fri Jun 05 1987 10:51 | 8 |
| I just remembered reading somewhere (I can't remember right
now) that the very first objects into interplanetary space was NOT
LUNA 1, but fragments of metal shot into space by a single stage
rocket from the US in April of 1957. I wish I could remember more
about it; can anyone?

| RE: .6 and .7
While it was Gemini 6 & 7, Gemini 7 was launched first. This is
the only time, to my knowlege, that manned missions were launched
out of sequence.

296.12 | Other out of order flights | VMSDEV::FISHER | Burns Fisher 381-1466, ZKO1-1/D42 | Wed Jun 10 1987 13:57 | 18 |
| re .11: You are right about 7 being launched first. It was intended
to be a "long duration" (about 2 weeks) mission. G6 was launched
2nd to rendezvous with 7. This was also the time we had our plastic
bag problem...G6 shut down a few seconds after ignition (but before
liftoff, thank heaven). They discovered that there was a plastic
bag that had been left somewhere in the engine, although I am not
sure that was the immediate cause of the shutdown. There was a
plug that fell out early.
However, I don't think you are correct about out-of-sequence flights.
For example, the Challenger flight was 51L (forget the letter).
However, Bill Nelson's flight a couple weeks before was 61A or some
such. In other words, the Challenger flight was scheduled for fiscal
year 85, but got delayed to 86, while Nelson's flight got off in
the fy that was planned.

296.13 | FY:85 | ENGGSG::FLIS | | Thu Jun 11 1987 09:34 | 6 |
| Flight 51L was launched in January, 1986. I am not sure what NASA
uses for its fyscal year but January, 1986 would be FY:85 at DEC.
FY:86 begins the first week of July, 1986

296.15 | | MONSTR::HUGHES | Gary Hughes | Thu Jun 11 1987 14:45 | 7 |
| I think the flight numbering has nothing to do with reality. Rather
it is a function of what year's flight budget it came out of, or
something like that. I have something at home that explains how
the numbering scheme works and if I can remember what it is, I'll
look it up.

296.17 | Numbering scheme explained | VMSDEV::FISHER | Burns Fisher 381-1466, ZKO1-1/D42 | Fri Jun 12 1987 14:05 | 26 |
|
The federal govt's fy begins in October. I think that FY86 begins
in October 85.
The numbering scheme is as follows:
5 1 L
^ ^ ^
| | |
| | -----The "Lth" (i.e. 12th) mission of the fy
| --------Launch from KSC (Vandenberg is 2)
----------Planned launch in FY 85
So one can order missions in their planned launch order by sorting
first by FY and then within each year, sorting by letter.
The mission that was launched just before 51L was 61A. Thus 51L
was out of order. (There was also one or 2 '85 missions that were
out of order within 85, and there was at least one that was dropped.
I think either J or K was not flown.)
Now, that we have gotten sufficiently off the track of Agenas, I
might as well also add that they are dropping this BS numbering
scheme. The next mission is called STS-26.

296.18 | Shuttle flight codes | CRVAX1::KAPLOW | There is no 'N' in TURNKEY | Fri Jun 12 1987 16:34 | 10 |
| NASA (and I think the entire federal bureaucracy) starts its
fiscal year October 1st. The first 9 shuttle missions were
numbered STS-n, since then they are coded xy-a where:
x is the last digit of the scheduled fiscal year
y is the launch site (1=KSC, 2=Vandenburg)
a is a sequence letter
Canceled mission codes are not reused, thus there have been both
out of sequence missions, as well as never flown missions.
