The Apollo astronauts also trained at (in) Meteor Crater in the Flagstaff
area (Arizona).  There is now a museum with a space shop.
Caution: they ease you by 6$. Compared to a KSC visit it's not worth.

I assume, then, that someone at Thiokol put on their "manager's hat" and said
that pissing off the customer by delaying shipment of the SRB to look inside
it was a bad idea, regardless of where that tool might have ended up.

Why do I get the feeling that Thiokol "manager's hats" are shaped like cones?

From another space forum
>  NOW WHERE DID I LEAVE THOSE PLIERS?
    When workers at the Kennedy Space Center disassembled the STS-56
 solid rocket boosters they were surprised to find a pair of pliers
 lodged into the outside base of the right hand SRB.  The tool survived
 the trip from the launch pad up to approximately a 250,000 foot
 altitude, then down to splashdown and towing back to KSC.

    NASA spokesperson Lisa Malone told the media,

    "It's been a long time since something like this happened.  We've
 lost washers and bolts (before) but never a tool like this."

    The initial investigation into the incident has shown that a
 Thiokol Corp. technician noticed and reported his pliers as missing on
 April 2nd.  Unfortunately, the worker's supervisor did not act on the
 report and Discovery was launched with its "extra payload".  NASA
 officials were never told of the missing tool before the April 8th
 launch date.

    The free-flying pliers were supposed to be tethered to the SRB
 technician.  When the tool was found in an aft section of the booster,
 its 18-inch long rope was still attached.  The pliers were found in a
 part of the booster which is not easily visible from the launch pad.
|(Ron's ed. note:  naaahhh,  just too easy)

    A spokesperson for the Lockheed Space Operations Company said that
 the Shuttle processor will take "appropriate action".  Thiokol is a
 subcontractor to LSOC for work to prepare Shuttle hardware for launch.

Newsgroups: sci.space

I was reading Popular Science this morning and was surprised by an ad in
the back.  I know that a lot of the ads in the back of PS are fringe
science or questionablely legal, but this one really grabbed my attention.
It was from a company name "Personal Missle, Inc." or something like that.

Anyhow, the ad stated that they'd sell rockets that were up to 20' in length
and engines of sizes "F" to "M".  They also said that some rockets will
reach 50,000 feet.

Now, aside from the obvious dangers to any amateur rocketeer using one
of these beasts, isn't this illegal?  I can't imagine the FAA allowing
people to shoot rockets up through the flight levels of passenger planes.
Not to even mention the problem of locating a rocket when it comes down.

And no, I'm not going to even think of buying one.  I'm not that crazy.

The situation in this regard has changed considerably in recent years.
See the discussion of "high-power rocketry" in the rec.models.rockets
frequently-asked-questions list.

This is not hardware you can walk in off the street and buy; you need
proper certification.  That can be had, mostly through Tripoli (the high-
power analog of the NAR), although the NAR is cautiously moving to extend
the upper boundaries of what it considers proper too.

You need special FAA authorization, but provided you aren't doing it under
one of the LAX runway approaches or something stupid like that, it's not
especially hard to arrange.

As with model rocketry, this sort of hardware is reasonably safe if handled
properly.  Proper handling takes more care, and you need a lot more empty
air to fly in, but it's basically just model rocketry scaled up.  As with
model rocketry, the high-power people use factory-built engines, which
eliminates the major safety hazard of do-it-yourself rocketry.

Could it be Public Missile, Inc in Michigan?

From the description of ad here, it sounds like they're talking about
"High Power Rocketry", an outgrowth of model rocketry.  This hobby
uses non-metallic structural compoments and commerically manufactured
engines ranging in impulse classification from G to P.  The hobby
has been flourishing from early 1980s and is becoming increasing popular.
Technically this is not consider amateur rocketry.

Any rocket with a liftoff weight greater than 3.3 pounds OR using a
total impulse of G or greater, REQUIRES an FAA waiver to launch.
Typically, a group of people get an FAA waiver for specified period
of time (ie week, weekend, etc.) at a designated site and time, and
all of the launches are then covered under this "blanket waiver".
There is also a "High Power Safety Code" which designates more
specific rules such as launch field size, etc.

Finally, in order to purchase any of the larger (Class B) rocket
motors you need to certified through either the National Association
of Rocketry or Tripoli Rocketry Association. Certification procedures
require a demonstarted handling and "safe" flight at a total impulse
level.

For more information, watch rec.models.rockets newsgroup.

Let's see. These aren't, in a strict sense, amateur rockets. That term
denotes rockets, the engines of which are constructed by the user. The
rockets you describe are called HPR, or high power rockets, to
distinguish them from (smaller) model rockets. They use factory-made
ammonium perchlorate composite propellants in phenolic plastic engines
with graphite nozzles. The engines are classified by impulse. A "D"
engine, for example, can have no more than 20 newton-seconds of impulse.
An "F" engine can have no more than 40 ns. Each letter corresponds to a
doubling of the maximum impulse. So far, engines up to size "O" are
available pretty much off the shelf. Engines of size H and above are
shipped as Class B explosives, and as such are controlled. Engines of
size F and below are shipped as Class C explosives, and are not as
controlled. Class F engines, BTW, are not HPR engines, but model rocket
engines. (Class G engines go in and out of legal limbo.)

There is an HPR Society, The Tripoli Rocket Society, I believe, which
holds events at various sites throughout the year, with all legalities
(FAA waiver included) taken care of. The National Association of
Rocketry is more concerned with engines below H, though it is involved
in HPR as well. These societies certify users of HPR rockets, and
companies will not sell to uncertified individuals.

Bottom Line: It's legit. I suggest you send for a catalog - but forget
the dynamite, will ya?

Actually, they are legal! I not familiar with the ad you are speaking of
but knowing Popular Science it is probably on the fringe.  However, you
may be speaking of "Public Missle, Inc.", which is a legitimate company
that has been around for a while.

Due to advances in composite fuels, engines are now available for model
rockets using similar composites to SRB fuel, roughly 3 times more
powerful than black powder motors.  They are even available in a reloadable
form, i.e. aluminum casing, end casings, o-rings (!).  The engines range
from D all the way to M in common manufacture, N and O I've heard of
used at special occasions.

To be a model rocket, however, the rocket can't contain any metal
structural parts, amongst other requirements.  I've never heard of a
model rocket doing 50,000.  I have heard of > 20,000 foot flights.
These require FAA waivers (of course!).  There are a few large national
launches (LDRS, FireBALLS), at which you can see many > K sized engine
flights.  Actually, using a > G engine constitutes the area of "High
Power Rocketry", which is seperate from normal model rocketry.  Purchase
of engines like I have been describing require membership in the National
Association of Rocketry, the Tripoli Rocketry Assoc., or you have to
be part of an educational institute or company involved in rocketry.

Amatuer rocketry is another area.  I'm not really familiar with this,
but it is an area where metal parts are allowed, along with liquid fuels
and what not.  I don't know what kind of regulations are involved, but
I'm sure they are numerous.

High power rocketry is very exciting!  If you are interested or have
more questions, there is a newsgroup rec.model.rockets.

It still applies, except the astronomy these days is Very Long Baseline
Radio Astronomy coupled to GPS and Satellite Laser Ranging. The data
from NASA's and the Naval Observatory's (among others) is a vital
source of data for studies into crustal dynamics, Earth rotation, and
purturbations. Every time there is a leap second added to the New Year,
remember the military and science are still co-habiting nicely. The
same VLBI was used to track Gallileo as it passed the Earth, and used
so little fuel that it can afford to observe Ida.

Well, first you work out how much cold gas you need, then make the
tanks big enough.

Working out how much cold gas is another problem, depending on
vehicle configuration, flight duration, thruster Isp (which couples
into storage pressure, which may be a factor in selecting tank
wall thickness etc.)

Would the sub-orbital version be suitable as-is (or "as-will-be") for use

As an Amateur Radio operator (VHF 2metres) I like to keep up with what is
going up (and for that matter what is coming down too).

In about 30 days I have learned ALOT about satellites current, future and
past all the way back to Vanguard series and up to Astro D observatory
(space).  I borrowed a book from the library called Weater Satellites (I
think, it has a photo of the earth with a TIROS type satellite on it.)

I would like to build a model or have a large color poster of one of the
TIROS satellites I think there are places in the USA that sell them.
ITOS is my favorite looking satellite, followed by AmSat-OSCAR 13
(AO-13).

Their Hiten engineering-test mission spent a while in a highly eccentric
Earth orbit doing lunar flybys, and then was inserted into lunar orbit
using some very tricky gravity-assist-like maneuvering.  This meant that
it would crash on the Moon eventually, since there is no such thing as
a stable lunar orbit (as far as anyone knows), and I believe I recall
hearing recently that it was about to happen.

Personnally, I don't know, but I'd like to try it sometime.

Programmatically, yes, we can land an Orbiter with a 5 cm hole in
the wall -- provided that the thing which caused 5 cm hole didn't
cause a Crit 1 failure on some of the internal systems.  There are
a few places where a 5 cm hole would cause a Bad Day -- especially
if the 5 cm hole went all the way through the Orbiter and out the
other side, as could easily happen with a meteor strike.  But a
hole in the pressure vessel would cause us to immediately de-orbit
to the next available landing site.

Apologies if this gets posted twice, but I don't think the first one
made it.

   FOR IMMEDIATE RELEASE           Contact:  OASIS [phone]

   15 April 1993                                Los Angeles, CA

     LOCAL NATIONAL SPACE SOCIETY CHAPTERS SPONSOR TALK BY L.A.
  ADVOCATE OF LUNAR POWER SYSTEM AS ENERGY SOURCE FOR THE WORLD

   On April 21, the OASIS and Ventura County chapters of the National
Space Society will sponsor a talk by Lunar Power System (LPS) co-
inventor and vice-president of the LPS Coalition, Dr. Robert D.
Waldron.  It will be held at 7:30 p.m. at the Rockwell Science
Center in Thousand Oaks, CA.

   Dr. Waldron is currently a Technical Specialist in Space
Materials Processing with the Space Systems Division of Rockwell
International in Downey, California.  He is a recognized world
authority on lunar materials refinement.  He has written or
coauthored more than 15 articles or reports on nonterrestrial
materials processing or utilization.  Along with Dr. David
Criswell, Waldron invented the lunar/solar power system concept.

   Momentum is building for a coalition of entrepreneurs, legal
experts, and Soviet and U.S. scientists and engineers to build
the Lunar Power System, a pollution-free, energy source with a
potential to power the globe.

   For the past three years members of the coalition, nearly half
from California, have rejuvenated the commercial and scientific
concept of a solar power system based on the Moon.

   The LPS concept entails collecting solar energy on the lunar
surface and beaming the power to Earth as microwaves transmitted
through orbiting antennae.  A mature LPS offers an enormous
source of clean, sustainable power to meet the Earth's ever
increasing demand using proven, basic technology.

   OASIS (Organization for the Advancement of Space
Industrialization) is the Greater Los Angeles chapter of the
National Space Society, which is an international non-profit
organization that promotes development of the space frontier.
The Ventura County chapter is based in Oxnard, CA.

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.
