I was rewatching the curiosity launch and noticed a thin bent tube rocket firing on the side of the fairing right before fairing sep...what is the engineering and aerospace reasoning for this?

Atlas V launch drinking game: when someone asks this question, drink. When someone answers accurately, drink. If Jim is first, drink again.

Congratulations to the Atlas and MSL teams, and to NSF for its usual excellent coverage.
Onward to Mars!

I was on top of the LCC at Kennedy for the MSL launch. Here's a video I shot of the launch. Enjoy!

Why is the US public misinformed about the US space program? NBC news stated in it's coverage of the launch that a "Saturn 5" launched the probe. I thought I was imagining it until it was verified by the closed caption text. Sigh...

Misinformed is probably too big a word. If it really happened (I admit it borders on comedy) it was someone's stupid error. I don' think NBC has some secret agenda to misinform people about rocket types. Most people probably don't care or don't even know about Atlas V or Saturn V.

wicked sound. Have to get down there for one of those launches one day.
Thanks for sharing!

Ha! You think that's bad...
This morning John Zarrella over at CNN informed those who actually still watch CNN that NASA's budget is ONLY 5 cents on the tax dollar.
Can you imagine?!?! Thanks for the ~10x increase John!

I like that there are headlines now like this:
"NASA launches largest-ever Mars rover"
"largest-ever" as if to imply that there have been many (just three others)
you forgot the minuscule PrOP-M "walkers" on the Russian landers

It makes you wonder what the reporters actually do all day. I'm sure there are some good ones out there but the "impression" I get is that the news media has completely given up on accuracy and integrity of reporting. I watch the the world and national news every night at 6:30 out of habit after watching the local news at 6:00 (which I do trust) and every night I catch them in at least 1 glaring error but nobody seems to care. The only thing I get out of each story is that "something" happened. As to the accuracy of what they say - well I don't believe a word they say because half the time it's pretty obvious that they don't have a clue what they are talking about. Just a bunch of high paid talking heads.

Status report from an engineer
http://www.unmannedspaceflight.com/index.php?s=&showtopic=7138&view=findpost&p=180859
Nice. Site owner Doug (who I've met, and is a top bloke) works for JPL now too, but they'll be good with this coast phase as this is their bag.
We'll set up our post S/C Sep style thread on Monday on our new section. We might be able to add something to the party, as we started to get some good L2 info per NPP's post S/C Sep - but we'll be heavily referencing/linking USMF as they are excellent and a friend of NSF.

My only limited educated guess is for fairing sep stabilization...
Thx.

Thx. Silly me I forgot that the Centaur stage is enclosed too...

Yesterday during the first Centaur burn, I asked the following question:
Why was the telemetry briefly showing the altitude as greater than the apogee altitude?
Nobody responded to it; I guess it was missed in the excitement. I reviewed the launch video, and it happened between approximately 475-625 seconds into the mission at about 130 nm altitude. A couple of the screenshots posted shortly before my comment clearly show it, especially robertross' 76.JPG. Both before and after that period, the apogee altitude was greater.
(In fact, I originally typed "Why *is* the telemetry", but before I hit post I saw that that was no longer the case, so I amended it to "Why *was*".)

I did enjoy. Thanks!
If you get to do this sort of thing a lot, there's a relatively-small and inexpensive photography accessory that I've found to be pretty good and a huge help at exactly this sort of thing - a Manfrotto 701 tripod head (i.e. 701HDV). It's a fluid head that makes tracking massively easier than a regular head. Just a thought and thanks for the video!

Because the ascent profile required to gain altitude first, and then orbital speed (expending some previously gained altitude in the process).

Who said space exploration was uncool? Will.i.am of the music group Black Eyed Peas was a member of the NASA Tweetup group that saw MSL launch yesterday. (Though I'm wondering if this post should go in the Orion thread instead considering where the rapper is in this photo)
On a similar note, the wife of Seth Green (who does voices on Family Guy and Adult Swim) was a member of the JPL Tweetup that I attended last June
