Hi, this is Morris Jones, a long-time lurker but new poster.
I thought it would be worth exploring a few lunar missions that don't seem to be discussed much at the moment. The exact fate of some of these missions is open to question. Let's see if we can work out what's going on.
International Lunar Network: This was announced with fanfare a few years ago. Little more has been generally discussed. The whole thing seems to be going through committee meetings, with a lot of details unresolved.
LADEE: Is this still on target? There were suggestions two years ago that cost overruns in the Mars Science Laboratory could gobble funds from this and other missions. This was later dismissed. Then MSL grew more hungry, and the subject was open to discussion again.
GRAIL: Not much more talk, but apparently still actively in development.
Luna-Glob: The recent delay in Phobos-Grunt could influence its own launch timetable.
American Student Moon Orbiter: The silence is deafening.
Reports on the status of any of these missions would be appreciated.
Cheers,
Morris

Artemis Update - It seems that the P1 Artemis lunar orbiter (aka Themis P1) has successfully performed Lunar Flyby #1 a few weeks ago on December 8, 2009. This sets it up for Lunar Flyby #2 on January 31, 2010. The other Themis/Artemis lunar orbiter, P2, will require only one lunar flyby, and that will occur on March 28, 2010. Artemis has a Twitter occount for frequent updates -

In addition, here is the link to a very good summary of Themis and Artemis, including diagrams of the trajectories that P1 and P2 will take on their way to LOI for both probes in April 2011 -

A great mission for lunar science and trajectory analysts!
