Lunar Reconnaissance Orbiter launch to be delayed a bit

From here:

As of this morning LRO was notified that problems with the WSG spacecraft have made it impossible for ULA to launch LRO/LROCSS on 4/24/2009. The next set of LRO/LCROSS launch days opens on 5/7/2009. Both LRO and ULA are replanning for 5/7/2009 as of this morning.

Please note that this is unrelated to the booster tank issues and that there are still unresolved issue with a west coast Delta launch (STSS) that is scheduled for 5/5 and will have to move to late May to enable ULA/KSC to launch LRO/LCROSS on 5/7. The current thinking is this will be arranged but is not yet confirmed.

Launch delays aren't that big a deal with the Moon though, since it orbits us instead of the Sun so there's no worry about having to wait another year or two for the next launch window. This is one of the primary reasons for arguing for a colonization of the Moon before Mars - location, location, location.
