LPSC 2016: The Moon Keeps on Giving

Ryan Clegg-Watkins • April 14, 2016

There was no shortage of interesting lunar science talks at last month’s Lunar and Planetary Science Conference. Dr. Ryan Clegg-Watkins highlights some of the interesting results for us.

Snapshots of Science from the 2014 Lunar and Planetary Science Conference

Emily Lakdawalla • March 25, 2014

Vignettes from dozens of LPSC talks: GRAIL and LADEE at the Moon; ice and craters and conglomerates and organics and gullies on Mars; polar deposits and volatile elements on Mercury; tectonics on Enceladus; and more, until my brain was so full I could barely speak.

Fly me to the Moon

How GRAIL will meet its end

Emily Lakdawalla • December 13, 2012

The twin GRAIL spacecraft are nearly out of fuel, and are being directed to a controlled impact near the north pole on the near side of the Moon on December 17. Before the end, though, they did some cool things, including flying within 2000 meters of mountaintops, and catching video of Lunar Reconnaissance Orbiter in flight.

This month, Opportunity is roving again, while Curiosity approaches Mars; Cassini's finally seeing rings, and will fly by Mimas, Titan, and Tethys; GRAIL has completed its primary mission and is journeying toward the second; Dawn is climbing to the HAMO2 orbit; and a rare transit of Venus is coming up on June 5/6.

Good news, bad news: GRAIL science underway, Venus Express suffers storm damage

Emily Lakdawalla • March 08, 2012

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.

GRAIL MoonKAM's first (released) video of the Moon

Emily Lakdawalla • February 01, 2012

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.

Geek craft: GRAIL twins Ebb and Flow in plastic canvas

Emily Lakdawalla • January 25, 2012

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.

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.

GRAIL update: Next launch attempt planned for Saturday

Emily Lakdawalla • September 08, 2011

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

From the "Just Plain Cool" department: Time-lapse photo of GRAIL's Delta 2 tower rollback

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.

How to watch the GRAIL launch on Thursday

Emily Lakdawalla • September 06, 2011

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.

Nifty GRAIL animation

Emily Lakdawalla • August 25, 2011

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.

GRAIL twins together on their rocket

Emily Lakdawalla • August 18, 2011

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