Deep Impact / STS114 Launch Date/time

Thu Jun 30, 2005 11:23 pm

Some Space Doings This Weekend:

1. The STS114 Flight Readiness Review concludes today. We should have a firm launch date/time by the end of the afternoon. Nasawatch.com says the FRR may conclude as early as noon. Press has been alerted that a news conference will be held immediately (30 min) following the conclusion of the FRR.

2. Deep Impact plows into it's comet on July 4th at 1:52AM EDT (05:52UTC).
The impact MAY be visible naked eye for persons in the Pacific Ocean area. See links below for additional details.

NASA TV has a bunch of coverage scheduled at this link:

July 13th NASA has said.
I dont like it IMO, any date other than 13, 13's NASAs unlucky number, why not the 12th or 14th.
Its not the fall that kills u, its the sudden stop at the end..

Why is 13 NASAs unlucky number? Why not 107, 51, 1, or 28?

If anyone is wondering what we're talking about...NASA set STS114s firm launch date as 13 Jul at this mornings Flight Readiness Review.

I figure that the 13th is for dress rehearsal for STS-114. I suspect that NASA will be very gun shy and want to be sure before launch. I would look for the second effort a week or so later but I hope I am wrong as I have purchased tickets for the launch and planning vacation around that time frame. The stated launch window 13th through the 31st. That should be about 3 tries to get her off the pad I am guessing.

Depends on what causes the various 'aborts/scrubs'. If it's WX They can cycle several times for 24 hours at a time*

Given
http://spaceflight.nasa.gov/shuttle/ shows 3:51 p.m. EDT I'll bet tons of cash WX will be a factor for this time of year. Until the window moves to early morning (dawn+ a couple of hours)..WX scrubs for every launch attempt near this time.

*forgive me for not considering the ISS orbit as I know the ISS has to basically be right above the STS when the launch occurs. This probably is a factor in them not cycling in a 24 hour period like they used to.

The ISS itself does not have to be right above the pad. The plane of the ISS orbit must intersect the pad however, that's why the window is so short. They said at the press conference that doing a 24 hour recycle forces them into a flight day 4 rendezvous vs the planned flight day 3. They can't do a flight day 4 rendezvous due to this flight lacking the consumables to support a end of mission contingency day for that scenario. Something to do with manuevers required to photo the ET requiring more propellant than a regular launch. That's what I got from listening to all the NASAspeak anyway....

edit: ISS will be over the Indian Ocean at 15:51EDT 13 Jul... FYI....

If anyone is staying up to watch the Deep Impact mission tonight....

Here's a website with pix of the comet from Kitt Peak. Pix update every 45sec and they have a loop running...

been watching it on NASATV (I still am on the web lol), that impact shot the first RAW image from the "mothership" was amazing, lol stunning even.
Couldnt have gone any better for NASA, well done  Smile

I'd love to know what the secondary explosion has been caused by (the top right of the initial impact), wether its possible gasses being exploded or some sort of ejeta being blown away by the comet.
One theory I have is that the impact site is actually where the seconday explosion is in the top right, and that the "explosion" is actually taking place high above the comet, we saw the same thing as on Jupiter when Levy9 hit and perhaps the same physics are being implied here.
Also dont forget in space there is no sound, so the energy is actually more "impact" and focused on one specific area, rather than being disperesed by soundwaves which help radiate some of the explosion "waves" and partly disperse heat when combined with oxygenated molecules.

Good shooting by JPL/NASA, a fine 4th July celebration for them.

Interesting to see just how the comet has been affected, crater size/type etc.

First lookback image I've seen.....

I've seen a spectacular movie of the actual impact on NASA TV but I don't see it on the web anywhere.... Sad
