A solar eclipse isn't just a spiffy sight to Earthlings; it looks pretty cool to lunar dwellers as well.

Grab your red-blue 3D glasses and dive in to this small but spectacular unnamed lunar crater as seen in a Lunar Reconnaissance Orbiter photo.

It is always thrilling to see relics of human exploration out there on other worlds. Today, the Lunar Reconnaissance Orbiter Camera team posted some new photos of two defunct spacecraft: the Luna 17 lander and the Lunokhod 1 rover. I've posted images of the two craft before, but the ones released today are much better.

Two brief mission updates. First, the good news: NASA announced yesterday that the twin GRAIL spacecraft have begun the science phase of the mission, transmitting precisely timed signals to each other in order to map the Moon's gravity field. The bad news: according to ESA, since the recent solar storm passed Venus, both of Venus Express' star trackers are suddenly unable to detect stars.

Here's the first release from MoonKAM, tiny cameras included on both GRAIL spacecraft whose only purpose is public outreach. Classrooms can sign up for opportunities to propose sites to image.

Those of you who follow me on Twitter know that after beginning with Dawn last week, I've kept my fingers busy, stitching more spacecraft from plastic canvas. I now have prototypes for GRAIL, New Horizons, and MESSENGER.

The twin GRAIL spacecraft are nearly at the end of their three-month cruises to the Moon. Currently being discussed is an extended mission for GRAIL that would begin after the June eclipse and last through most of December 2012.

After some exasperating delays due to pesky and changeable high-level winds, the twin GRAIL spacecraft launched this morning on their trip to the Moon.

GRAIL is trying for launch today at 8:29 PDT / 12:29 UT or 9:08 PDT / 6:08 UT., and here I am at 5:00 am my time ready to watch. As before, I'm watching the feed through Spaceflight Now's GRAIL mission status center.

Just a brief update: SpaceflightNow reports no attempt will be made to launch GRAIL tomorrow. The next launch opportunity is Saturday.

On September 6, NASA released new high-resolution photos from the Lunar Reconnaissance Orbiter (LRO) showing the Apollo 12, 14 and 17 landing sites from vantage points as close as 21 kilometers.

The terrific launch photographer Ben Cooper is at the Cape waiting for GRAIL's Delta 2 rocket to take off, and last night he took this very cool photo.

The twin spacecraft of the GRAIL lunar gravity mission are set to launch side-by-side on a Delta II rocket on Thursday, September 8. Here's all the places where you can find information about the upcoming launch.

A pair of lunar spacecraft is launching in two weeks, and NASA had their preview press briefing this morning. Notable from that briefing was this spiffy video.

It's the first time I've ever seen anything like this -- two identical spacecraft, side by side on one launch adapter ring.

According to an article published a week ago by the Xinhua news service, Chang'E 2 departed the Moon on June 9 at 09:10 UTC. It's now headed toward a Lagrangian point in space, but not the one I thought it was headed for.

According to a story posted on xinmin.xn and run through Google Translate, there's now been an official announcement from China about Chang'e 2's extended mission: it will depart lunar orbit in mid-June and journey to L2.

Here's a very pretty picture to start off the week: a really gorgeous fresh crater on the lunar farside. There's nothing particularly unusual about this crater; it's just recent and fresh so there's a mesmerizing amount of detail in the feathery patterns of the ejecta that fans outward from it.

In a paper recently published in the Journal of Geophysical Research, Georgiana Kramer and several coauthors performed a careful comparison of two data sets that seem like they're measuring the same things, so you'd think that the measurements they took would match between the two instruments. But they don't quite match.
