32. Ringing in the New Year with two new arrivals to the Moon

(Web Page; Sat Apr 19 14:14:00 CDT 2014)

The twin GRAIL spacecraft are nearly at the end of their three-month cruises to the Moon. On New Year's Eve at 21:21 UTC, GRAIL-A will enter orbit, and GRAIL-B will follow on New Year's Day at 22:05. Each will fire its main engine for ab...

Description: 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.

33. What's up in the solar system in September 2011

(Web Page; Mon Dec 30 19:29:00 CST 2013)

September is going to start with a bang: the twin GRAIL spacecraft are set for launch on September 8. I would love to be able to attend the launch but my older daughter's first day of kindergarten is September 7! That's a launch of a dif...

Description: September is going to start with a bang: the twin GRAIL spacecraft are set for launch on September 8. I would love to be able to attend the launch but my older daughter's first day of kindergarten is September 7! That's a launch of a different kind.

34. If it's March, it must be LPSC

(Web Page; Fri Mar 13 13:10:00 CDT 2015)

Next week is the 46th Lunar and Planetary Science Conference (LPSC), a weeklong meeting held every March near Houston. It's the largest annual gathering of planetary geologists. It always delivers healthy servings of Moon, Mars, and mete...

Description: Next week is the 46th Lunar and Planetary Science Conference (LPSC), and Emily Lakdawalla will be attending to tweet and blog about news from Rosetta; Curiosity; MESSENGER; GRAIL; Chang'e 3; Dawn; New Horizons; Cassini; and more.

35. Snapshots of Science from the 2014 Lunar and Planetary Science Conference

(Web Page; Tue Mar 25 14:46:00 CDT 2014)

I'm finding it unusually difficult to select stories to tell you from this year's Lunar and Planetary Science Conference (LPSC), held all last week near Houston, Texas. It's not for any lack of material: I was there for five days straigh...

Description: 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.

36. What's Up in the Solar System in June 2012

(Web Page; Sun Mar 01 17:56:00 CST 2015)

Welcome to my monthly roundup of the activities of our intrepid robotic emissaries across the solar system! Probably the most anticipated celestial event of the month is not happening on a spacecraft; it's the June 5/6 transit of Venus, ...

Description: 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.

37. Antennas of the Canberra DSN at work

(Web Page; Thu Jan 10 17:47:00 CST 2019)

Description: Radio antennas in Australia track the twin GRAIL spacecraft on the way to the Moon. In the center is the 34-meter DSS-34 tracking GRAIL-A and at right is DSS-45 on GRAIL-B. In the left background, 70-meter DSS-43 is tracking STEREO-B.

38. What's up in the solar system in March 2012

(Web Page; Wed Aug 29 15:52:00 CDT 2012)

The event that will probably generate the most planetary news in March is the 43rd annual Lunar and Planetary Science Conference (Twitter hashtag: #LPSC43), which will take place from March 19-23 in Houston, Texas. Geologists who study s...

Description: This month will see GRAIL begin its science mission measuring the Moon's gravity field. MESSENGER will complete its primary mission at Mercury, celebrating its one-Earth-year-in-orbit anniversary with a big data release, and immediately begin work on its one-year extended mission. Mars will pass its solstice, ushering in warmer days for Opportunity. Coincidentally, this month will see Jupiter's southern winter solstice, too, though there are no spacecraft there to notice it. Out at Saturn, Cassini will have two encounters with Enceladus this month, one of them distant, one of them at 74 kilometers altitude.
