Tonight's von Kármán Lecture: VSE
« on: 06/23/2006 02:28 am »

They've got a streaming link there, and post archived stuff.

He just showed 4-segment SRBs.

Man, he's also callous regarding current projects. I don't get that.

To his credit, he's surveying the ENTIRE VSE--all the way to Mars.

He is getting some of the system names mixed up.  Nothing that we haven't heard so far.

This is surreal, especially the audience!

Wow! He just confirmed the the ET-121 tank repair on the PAL Ramp!

They've been trying to keep that quite for longer than I can remember.

What exactly do you mean by that?  I turned off the lecture because there seemed to be nothing new.

He took questions from the audience (from which they asked about everything and anything). One asked what the problem was with the tank to cause the mods (paraphrased) and he said that the tank suffered a repair after there was some crushed foam in production. (the repair patch theory - which never got reported by other media, given we were a month old when we got hold of those images in the link above).

I'm planning on attending the second (repeat) lecture friday evening; any questions I should ask?

Simon ;)

Holy Madmen, Batman! I've watched this series for a couple of years now (check out the archives), and heard a LOT of oddball questions/audience members, but that guy takes the cake! He accused NASA of keeping secret just how well prepared we ALREADY ARE for going to Mars. He said something along the lines of, "Why don't you just come OUT with it? But that's fine, call me the crazy one!" folded his shoulders and Harumpf'ed. Sander jumped for another question.

This entire series is very dynamic. Some are loaded with scientific detail, others are more general/overview.

*just read simon's post* He MAY not know a lot of details, but it would be interesting to POLITELY ask him about the specification changes in the SDV, versus choosing Titan/Atlas. (bet he'll say they didn't rate out, per ESAS.) You won't want to press him, lest you look pedantic. He obviously/rightfully has a JPL focus in a community lecture.

Any.

They'll all be better than what was going on tonight :)

Where's Dr Stanley when you need him? His appearance at LaRC kicked arse. This one was a wet fart thanks to a dodgy audience.

I was waiting for a UFO question at one point.

if they're gonna use Titans, then we're pretty screwed  ;)

Remember JPL is not mainstream VSE.  Robotic missions and experiments are their forte.  They are only on perimeter.   I would not have expected anything revealing from this, also considering the audience.

I'm looking forward to Simon's report on what he managed to ask and get answered at tonight's session.

The lecture/presentation tonight was at Pasadena City College (across the street from Caltech), and the audience was a mix of students and retired-looking people, though I saw a few JPL badges being hastely stuffed into pockets...

The presentation was obviously tuned for the general audience, and the pictures were pure ESAS. There were a few interesting aspects to his speculation of a manned Mars mission; the picture of a LSAM landing on Mars was pretty hilarious, and he said you need to launch 600 tons to LEO for a manned mission, meaning 6 cargo launches. That number is most likely from the study two years ago that assumed 100-ton to LEO SDLVs; the current baseline CaLV would only need four launches...

There were some silly questions (e.g. "was the X-33 cancelled" and some paranoid questions about the Russians from a few greybeards), and I was kinda annoyed when a little kid asked if NASA was sending a probe to look for life on Mars and he danced around the question without even mentioning AFL. Instead of giving the kid something to get excited about, he just responed with PR BS about "we might do something in the future"...

My own question ("As we've seen lots of small changes to Constellation since last Sept., do you expect any significan changes going ahead?") got a canned response, but I did parse some data from the other answers: MSFC will probably manage all of the LSAM, Lunar sample return missions are in the works, and that MSFC thinks that the CaLV at 2-3 launches a year will have a payload cost of $1000/kg, a tenth of the Shuttle...

Thanks simon. That was about what I expected.

I try to catch these every month. The archives are pretty cool, even some of the older ones.

Next month's Cassini should be heavier on "data" and should be a decent overview of what they've done so far there.
