What's up in planetary missions in 2014

Emily Lakdawalla • December 31, 2013

With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.

Lunar Reconnaissance Orbiter spies Chang'e 3 and Yutu

Emily Lakdawalla • December 30, 2013

As promised, Lunar Reconnaissance Orbiter's sharp eyes spotted the Chang'e 3 lander and Yutu rover on the lunar surface on December 25. The hardware shows up as a few bright pixels throwing long, dark shadows, clearly visible in a before-and-after comparison.

Hangout on Air Friday, December 27 14:00 UT: Student Astronaut 10th Reunion

Emily Lakdawalla • December 27, 2013

When Spirit and Opportunity landed in 2004, I was with the science team in charge of a group of high-school students called the Red Rover Goes to Mars Student Astronauts. We're coming up on the 10th anniversary of the landings -- what have those "kids" grown up into?

Chang'e 3 and LADEE updates: Yutu active again, LADEE didn't detect landing

Emily Lakdawalla • December 20, 2013

Chinese state television broadcast a display of a Chang'e 3 lander image; the Yutu rover is awake; and LADEE reports a surprising non-detection of the Chang'e 3 landing.

Book Review: Alien Seas, and so much more

Emily Lakdawalla • December 19, 2013

Alien Seas is ostensibly a book about "oceans in space," but it delivers so much more. The slender volume contains essays by many active planetary scientists who also happen to be excellent writers, each one of them playing a different riff on the idea of oceans in different environments in the solar system.

Chang'e 3 update: 6 instruments active, new fan-produced landing video

Emily Lakdawalla • December 17, 2013

Today there was a lengthy press briefing by several members of the Chang'e 3 science team. A complete transcript was posted in Chinese. I have run it through two machine translators and found it to be quite informative, not just about the mission but also about attitudes about Chinese space exploration and foreign cooperation. I also have a cool fan-produced video to share.

Conversations with an interplanetary spacecraft: "Hi, Juno!"

Emily Lakdawalla • December 17, 2013

Enceladus huffs and puffs: plumes vary with orbital longitude

Emily Lakdawalla • December 11, 2013

In which I finally get around to writing about a paper published last August: Enceladus' plumes sometimes spout more and sometimes spout less, depending on where Enceladus is in its orbit. This discovery was enabled by Cassini's longevity at Saturn, and we'll be able to follow up on it, as long as Cassini is allowed to complete its mission.

Quick Chang'e 3 and Mars Orbiter Mission updates

Emily Lakdawalla • December 11, 2013
