I just love the technical quality of the discourse, here... smile.gif smile.gif smile.gif smile.gif smile.gif

The LRO photo category if you want to bookmark:

The date of April 24 remains "official" for now but the ELV status report NASA issued yesterday says that while no formal request to delay to the May window (April 24, 25 and then no launch dates till May 7) has been made yet, discussions are in work as to whether April 24 is still a possibility. There is another Atlas 5 slated to go first, already delayed several times to March 9 and now looking at a delay of a few more days itself. They normally need close to 60 days turnaround time so I would be surprised if they keep April.

Glad to see LCROSS and LRO in Florida now. Hopefully, they'll make the April launch...not that being delayed 2 weeks to May 7 is a bummer smile.gif

I think it is officially NET May 7th now; it's now under review in the ELV status report and on the NASA schedule and being they only had the 24th and 25th before bumping to the May 7th window...

Windows (EDT):

May 07 - 19:29:07, 10 mins
May 08 - 20:14:55, 60
May 09 - 21:50:31, 60

jamescanvin, you asked about the U.S. launching a lunar mission per year. It looks like it will be an average of one per year. GRAIL (which consists of two spacecraft) and LADEE will all launch together in 2011. Soon after that, NASA plans to launch lunar network spacecraft, which could be quite a large number of small landers (some from NASA, some from other nations). So, an average of one spacecraft per year could be maintained, though actual launches would not be every year.

New and final, hope, launch date.
May 15, 2009 Update
NASA decided to move the LRO/LCROSS from a June 2 window to a June 17 window so as to allow the LCROSS team additional time to mitigate a potential thrust disturbance associated with the Atlas V Centaur fill/drain valves.

A bit of LCROSS impact site updating is in order. The chance of launch date finally pushed the impact back to the south pole. The choice of pole matters because of libration - you want to impact at the pole which is librated towards Earth for the ground-based observers. The original launch last fall with impact very early this year favored the south. The delay into this spring favored the north. Even a June 2 launch still worked best for the north. But June 17th tips the balance back to the south again.

The exact target isn't chosen yet and won't be until the last minute, specifically to allow some early LRO observations to factor into the decision. There will be a meeting to discuss candidates before the choice is made. Shackleton crater is unlikely, though. My guess is Shoemaker or Faustini.

Any UMSFers planning to try to observe the impacts?

Phil

Re: Observing the LCROSS event...the impact is expected to be upto 10 times more energetic than Lunar Prospector which went down in July 1999, so scopes in the 10 - 12-inch range should turn up some nice views.

There's a very good article by R. Leno and R. Evans in Selenology Today ( http://digidownload.libero.it/glrgroup/selenologytoday9.pdf p 32 - 58 PDF file ~ 10Mb) for preparing for such impacts, as well as an extensive article in No 13 of that same publication by K.A. Fisher aimed particularly at observing amateurs -- giving practical advice and guide to the planning approach (see -- http://digidownload.libero.it/glrgroup/selenologytoday13.pdf PDF file ~ 7 Mb).

I'd guess Phil would like to comment on this Ranger 8 picture: http://www.moonviews.com/archives/2009/06/..._orbiter_r.html
as it's written that this is "related" to LCROSS, I took the liberty to post it here.
