NASA selected 21 Participating Scientists to join the Dawn team in 2010, prior to Dawn's arrival at Vesta in 2011. Since that time, Dawn Participating Scientists have made enormous contributions to the mission, as they do for most other NASA missions. But the status of a Participating Scientist program for Dawn at Ceres has been in doubt.
Venus Express, currently the only spacecraft orbiting our nearest planetary neighbor, will soon meet a fiery end in Venus' atmosphere. But its work isn't over yet. ESA will maneuver Venus Express to dip into the uppermost Venus atmosphere and study how the spacecraft responds to atmospheric pressure, giving ESA valuable experience in aerobraking.
Finally, a new drill site! For the first time in nearly a year, Curiosity has put drill bit to rock and acquired a new sample of Martian material for her analytical instruments to chew on. Scientific data collection at Windjana is now complete; Curiosity drove away last night, on sol 630.
New photos from ESA's comet-chaser show its destination comet, 67P/Churyumov-Gerasimenko, developing a coma.
Rosetta is in the final stage of its approach to comet 67P Churyumov-Gerasimenko. Yesterday, the spacecraft successfully performed the first of ten burns it needs to match velocity with the comet.
New Horizons team member Simon Porter reports on the state of the mission and Pluto system science from the recent science team meeting at the Applied Physics Laboratory.
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.
The Mars Exploration Rovers mission cruised toward the Martian spring, Opportunity is powered-up and cleaner than it has been since its first winter on Mars.
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.
At the Solander Point section of the rim of Endeavour Crater, Mars Exploration Rover Opportunity spent the month of March just off Murray Ridge working on its final targets in Cook Haven and dusting itself in the winds of winter, while MER mission officials on Earth were roving toward what may be the robot's current greatest potential threat – being cut from NASA's planetary science budget.
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.
