Old rocket science tied to today's at Marshall

Blow the forward port. Thrust falls to zero quickly.

Hoagland?

I didn't know that about the pop-top on the SRBs. Never thought about it, but it sure would need a solution, wouldn't it!

"Face on Mars" Hoagland?

[Chode]

is it just me or is it odd that the SRB joints have an upright "U" for the joint so when the solid propellent passes by the joint, it is burning DOWN INTO THE JOINT where as if the "U" were UP-SIDE-DOWN... as the propellent burns it's way past the joint, the O-Ring is untouched.

Is this particular specification wise?

Part of the weather issues with Shuttle are related to the fact that for some launch abort modes it has to be able to return to KSC for a landing.

There are also some structural issues related to high-altitude wind shears.

Finally, post-Challenger there were a lot of temperature-related constraints added to preculude the sorts of low-temperature effects that led to the O-ring failures.

Of all of these, I think the first (landing weather) is the primary constraint.

If something totally unrelated to the booster themselves goes wrong you have to wait till they have completed their burn to jettison the booster.

Not true. You just have to size the escape rockets to outrun the booster.

Last week I read that the plans for the Saturn V have been lost ....

Not true. The Saturn V can't be rebuilt, however -- it would be like trying to build a new '47 Chevy from a set of plans. The problem is that nobody makes things like '50s-era electronics or alloys anymore, and fabrication processes have changed tremendously.

R. Hoblein(sp?) was on the Art Bell Show (yeah, I know) a few weeks ago talking about how there are 700 boxes of raw footage, etc missing from the archives of the 1st moon landing.

Mr. Hoblein is FOS. The "missing" information is television moon footage that was collected from telemetry and stored on tape. The problem is simply this: NASA has many millions of big, circular data tapes. These tapes are undoubtedly in storage somewhere -- but since nobody has wanted for them in 30 years, they got lost.

Guys, I live in Huntsville. Duh, this is rocket city USA. Where do you want to go? The moon? Mars? Beyond? We will put you there. It has been our pride for many many years. I am not saying it will be cheap, but we deliver.

[Rockingham]

You are correct. The same criticism was made about the Shuttle design by the old German engineers who had made the Moon program work so well. Von Braun is said to have been moved to tears when asked about the Shuttle and to have warned that it would kill people. We shall see if the new design has some way to jettison the solid booster if it starts going wrong.

Youch! Sorry about that. Clipboard must not have picked up the link. Let's try again...

BTW, this is only good for like 7 days from the publishing.

Thanks :)

The plans for the Saturn V still exist but the ability to build it no longer exists although with enough time and resources, we could modernize the design and build them again.
