Less than a year from its rendezvous with dwarf planet Ceres, Dawn is continuing to make excellent progress on its ambitious interplanetary adventure. But once it gets to Ceres, just how will it go into orbit? Marc Rayman explains.
After completing the initial reconnaissance of the Kimberley outcrop two weeks ago, Curiosity is, at last, moving toward a drill site. The science team selected the location last week: a spot near the base of Mount Remarkable, into what they have been calling the "middle unit" at the Kimberley.
LADEE ended its mission as planned with a crash into the lunar surface on April 17. Just days prior, it turned its star tracker camera toward the lunar horizon and captured a striking series of images of the lunar sunrise and zodiacal light.

Rosetta and Philae have very nearly completed a six-week phase of spacecraft and instrument checkouts to prepare the mission to do science. Recently, the lander used its cameras for the first time since hibernation, producing some new photos of Rosetta in space.
The End of Opportunity and the Burden of Success
Can NASA sustain its golden age of planetary exploration?
The Opportunity rover and the Lunar Reconnaissance Orbiter are both zeroed out in NASA's 2015 budget. Learn why these missions face the axe and why the White House is forcing NASA to choose between existing missions and starting new ones.
Curiosity has been busy performing a survey of the Kimberley, walking the length of the outcrop and taking enormous quantities of photos. The team is now ready to go in for a closer look, and maybe even to drill.
We don’t hear a lot at the moment about Chang’E 3 and Yutu, the Chinese lander and rover which were all over the news a few months ago. But Phil Stooke has been collecting news online and in person last month at the Lunar and Planetary Science Conference and now tries to put it all together and address the current state of the mission.
NASA's LADEE Spacecraft to Fly Through an Eclipse, Crash into the Lunar Surface on April 21st
It's end-game for NASA's latest lunar mission
LADEE, NASA's latest robotic lunar spacecraft, will reach its planned end-of-mission on April 21st, when it will crash on the far side of the Moon.
Some arm faults caused delays on Curiosity's approach to Kimberley, but the rover is now parked at its north edge, examining the "striated unit" up close with arm-mounted instruments.
Rosetta has turned on its cameras and sighted its comet for the first time since waking from hibernation. Next activity: waking the Philae lander.
Since the last time I reported on ICE/ISEE-3, there have been several developments. Its signal has been detected by several Earth-based observers, and there is now some (though slight) hope of reestablishing command over the spacecraft.
With a series of drives over the last week, Curiosity is now approaching her next science stop at Kimberley. The distinctive knobs of the Kimberley outcrop are visible in photos taken on sol 569.

Rosetta's comet target, 67P/Churyumov-Gerasimenko, has emerged from behind the Sun as seen from Earth, and the Very Large Telescope has photographed it. The new images show that cometary activity has already begun as Rosetta approaches for its August rendezvous.
In a series of drives, Curiosity flew past the "striated terrain" that outcropped at Kylie, and is now negotiating her way around some rockier territory as she makes her way south toward the enticing outcrops of Kimberley.

Seeing hardware that was built by human hands sitting on the surface of another planet never, ever gets old. Today, the Lunar Reconnaissance Orbiter Camera team released two new images of Chang'e 3 and Yutu on the Moon.
Over the weekend, Chinese state news agency Xinhua reported in both Chinese and English a little bit more information on what has stilled the Yutu rover's motions across the lunar surface: "a control circuit malfunction in its driving unit."
