Since the LRO passed its Mission Rehersal today and is on track to launch on Wednesday next week, it seems like a good time to start a thread about the launch.
http://lunar.gsfc.nasa.gov/launch.html
From the link above, there will be a pre-launch webcast on Tuesday morning.
The launch is scheduled for 3:51 PM EDT (12:51 PDT) which is 1951 GMT Wednesday June 17. [Corrected -- thanks Gsnorgathon!]
When it actually starts sending back pictures, someone should probably start a separate thread, but I think it makes sense to have the launch discussion separate from both the Development and the Cool Pictures threads.

Go LRO! Hey, it kind of rhymes!
Boston (EDT) is 5 hours earlier than London so 3 + 5 +12 (for 24 vs 12) = 20. So launch will be 20:51 GMT the same day, June 17.
Will the delay to the latest Shuttle mission affect the launch schedule for LRO?
AFAICT, Floyd's mistaken. Because of Daylight Saving Time, you need to subtract 1 from the GMT offset. So the launch is scheduled for 1951 GMT.
That is true but for those of us who live in the UK\Ireland the local time is now in BST - British Summer Time - and it will be 20:51.
Thanks to mcaplinger for posting the useful http link. Now I have a better idea that to plan and prepare a launch needs lots of coordinations, choreography and synchronization between different areas. Not yet any space agency is able to manage multiple launch at very short time like an airport. It will be some day in the future with the technology of spaceport.
LRO's launch is pushed back to June 18, because the Shuttle is set to liftoff on June 17.

The Shuttle launc has been scrubbed again, for today. Unclear on how this affects plans for LRO on 18 June.
It won't affect the launch of LRO. It flies tomorrow.
I suspect time zones come into play here, but of course the scrub(s) do affect the launch of LRO.
The original Wednesday (US) launch was pushed back because of the first scrub.
The second scrub decision means that the Shuttle now stands aside for LRO to play through.
As noted above, first LRO launch attempt (1 second window) is now Thursday, June 18, at 5:12 p.m. US-EDT or 9:12pm GMT (UTC)
OR for the Canberra DSN (supporting the post launch acquisition) it will be 7.12am on Friday 19th June.
Not tomorrow that's for certain.
Let's just hope that the weather doesn't come into the game.
LRO Launch times for Thurs 18th. Also in the event of further postponement, Fri 19th and Sat 20th - 3 times per day.

Forget the previous, this is better... we're looking at Thurs eve 5.12 pm EDT, 00:12am Friday UK summer time

It looks like NASA TV coverage of the launch will begin at 2 p.m. June 18.
Heard on NASA TV that during the impact of LCROSS and it's lil' projectile, there will be live feed from the LCROSS mission control room, allowing us to see what's going on in real time. Anyone know where the link to that might be?
The rocket Centaur along with the shepherding space LCROSS will be traveling many elongated loops around Earth and Moon (going from South to North of Moon at 70 degree angle inclination) until the impact (both in a interval of 4 minutes, First Centaur and later LCROSS) at approximately October 8, 2009.

You're right, I was confusing my a.m's and p.m's. The current schedule still seems to be 5.12pm Thurs EDT, 10:12pm UK summer time. Apologies.
An MCS is progressing towards the cape, thunderstorms might interfere with the launch.

It will take a while for LCROSS to arrive, but we do get some calibration images during the swingby in only a few days.
Phil
cool! Thank you!
Read somewhere that Hubble will point towards the impact as well. Great photo opportunity!
And, I'm glad LRO will settle the silly conspiracy theories on the Apollo landings.
One of the deniers is busy flooding the Google Lunar X Prize forum with nonsense. (Hi, Sock!) There the obvious retort is - join a team and go see for yourself. But it's a waste of time. Not because they can't be convinced - because they know it's a lie from day one. The folk at the top don't believe it. They have other agendas.
Phil
... which are MAKING MONEY!
LRO launch isn't certain... We hope that the skies will clear, but it's not sure...
Looking good now for 5:32. The LROC site says they've launched - they didn't update the launch time!
Phil
Launch team polled. LRO is go for launch!
Proceeding with count!
I've seen rocket cams before, but never on a NASA-TV live broadcast of a launch. Thrilling.
TTT
And now we've had shot of the payload under the fairing. Amazing. Think of the rocket engineers who went through their careers without ever seeing a shot like that.
TTT
MECO! Main engine cutoff!
That rocket cam shot rising through the clouds was awesome!
I'm actually in Florida, so I went out on the balcony to look, but I'm afraid we're just a bit too far away to see it from here. Maybe if it had been a night launch. Still, it was cool to follow it online.
--Greg
LRO just successfully separated from the rocket! Congratulations all!
Separation .
I too tried to see it but it launched due east. I can see the shuttle when it goes NE but East is no good.
Looks good. Next significant news will be Lunar Orbit insertion on Tuesday morning at 5:43 a.m. EDT (0943 GMT).
From Spaceflight Now "T+plus 44 minutes, 45 seconds. SPACECRAFT SEPARATION! The Centaur upper stage has deployed the Lunar Reconnaissance Orbiter on its direct trajectory for the Moon. "

It seems so weird to read that LRO will reach its destination Tuesday morning,, we usually have many months or even years to wait for that.
I was playing around with the spreadsheet of the LRO priority targets. I found it interesting to do a sort on the priorities...25 Priority 1 targets, 1800+ Priority 2 targets, and 4400+ Priority 3 targets! I really appreciated the detail in the spreadsheet regarding why certain targets were identified as highest priority. It wasn't necessarily just to do with possible ice or potential for a lunar outpost, but many of the Priority 1 targets were suspected either to be the youngest or the oldest areas on the surface of the Moon.
Launch video (lotsa rocketcam with voiceover + sound from ground) on Youtube:
http://www.youtube.com/watch?v=j-5t4de6jjI&feature=related
About the speed trayectory of LRO/LCROSS from Earth toward Moon, I am still trying to learn and understand its evolution speed. However, I know that the minimum velocity required to escape from Earth gravity is around 11.6 kp/s and I have noticed thru the other source of information that the spacecraft was reducing its speed from 5 kp/s at about 35,000 km from Earth, 4kp/s even further from Earth. Then I tought that the LRO/LCROSS didn't reach the 11.6 kp/s to escape from Earth gravity in its way toward to Moon but at lower speed...
Then I realized the spacecraft speed will be reducing to the minimum speed until the Selene gravity captures it.
Is that my tought correct? Thanks for any comments.
According to NASA-Twitter, the midcourse correction burn was completed successfully. Also they have switched on the Russian instrument - LEND.
Hello guys,
thought I would register now that LRO has launched successfully
Another cool video is on ULA's website (http://www.ulalaunch.com/)
direct link: http://www.ulalaunch.com/launch/LRO/LROLCROSS_LaunchHighlights.wmv
I was lucky enough to be invited to the launch, and see it!
One of the pictures I took :
By the way, LRO has a blog with many updates about how it's doing and what's next:
http://lroupdate.blogspot.com/
Great!
I'm a little worried about the power drop. It's insignificant, but anyway..
The one thing I'm looking forward to more than anything else? Matching LROC images to the Soviet era map of the Lunokhod 1 route, to locate the old rover and its landing stage.
Phil
We don't know exactly where it is - that's why i'm looking forward to it. There is no doubt about where the Apollos and most Surveyors are, but the Lunas are not precisely located. Luna 9 and 13 will be very hard to find, with tens of images needed to cover the uncertainty ellipses. And if they are imaged, they may not be very easy to identify among the rocks. But for Lunokhod 1, there is a candidate site about 5 km from the tracking position which might be it. Only one or a few images would be needed to search for it.
Phil
Just to compare - we still haven't located Mars Polar Lander, Beagle 2, Mars 6 and Mars 3. I expect we'll be searching Luna 9, 13 for years.
the positions of Luna 17 and 21 (or rather, their Lunokhod rovers) are fairly well known, from Lunar Laser Ranging (mostly used to monitor the position of the Apollo retro-reflectors). I think Luna 21 is the least constrained of the two.
No, it's the other way round, though some web sources have it wrong. Lunokhod 1 has not been detected with the laser since early in the mission, in 1970. Lunokhod 2 gives a weak reflection but can be used today. A search for Lunokhod 1 is being undertaken through JPL but the full lat-long-range space has not been sampled and could take quite a while, even assuming the reflector is usable. There is at least a 5 km uncertainty on Lunokhod 1's location, but as I said there is a candidate location (made by matching the Lunokhod 1 route map to the best images of the site, which are not very good). I hope the candidate position is correct, because I suggested it, but wherever it is it will be good to have it at last.

LCROSS - Streaming Video Coverage of the Lunar Swingby
LCROSS lunar swingby video stream coverage will begin approximately 5:20 a.m. PDT on Tuesday, June 23, 2009.
The LCROSS instrumentation will send back data to Earth for approximately one hour. The first 30 minutes will contain a view of the lunar surface from an altitude of approximately 9,000 km. The video feed is set to display one frame per second. During the latter 30 minutes, the spacecraft will perform multiple scans of the moon's horizon to calibrate its sensors. During this latter half hour, the video image will update only occasionally. The 3D visualization stream will show the spacecraft position and attitude throughout the swingby.
Camera Feeds
The live streaming coverage of the lunar swingby will consist of two separate video streams:
Live video feed from the spacecraft's visible light camera at one frame per second. Real-time, telemetry-based animation of the lunar swingby.

Perhaps this should really go to a new thread for mission. We are certainly past launch.

LCROSS will perform 3 LGALRO, each lasts 38 days, before impacting to the Moon
http://lroupdate.blogspot.com/
The real need for a new thread is a dedicated LCROSS thread, I'd say. Pics in only a few days! Sounds like LROC pics will have to wait until about July 2nd.
Phil
As the first part of the question was answered, I'll go for the 2nd one.
NASA-Twitter reports that all systems perform wonderfully, which is great.
If you haven't taken a look yet, check out the LROC website. It's a great example of How A Mission Website Should Be Done. Clear, good links, looks great, the Outreach materials section is a goldmine, too :-)
http://lroc.sese.asu.edu/index.html
CAn't wait for the first images to appear in the gallery! :-)
Yes but some pages are clearly out of date....
"LROC images are not currently available, because the orbiter is still waiting for launch.
Once launched, the orbiter will began taking amazing pictures of the moon. "
Also why do we still need a "Launch Preview".
/padantic mode off
http://www.unmannedspaceflight.com/index.php?showtopic=6071&st=0#entry142273 for discussion during LOI / LCROSS flyby.
Looks like we're safely in orbit now. Even though I started this thread, I don't see how to close it. Can a moderator do that for me?
Thanks!
