After a journey of more than a decade, Rosetta has finally arrived at comet 67P Churyumov-Gerasimenko. Confirmation of the successful rocket firing came at about 9:30 UTC via a webcast from ESA's Operations Centre in Darmstadt, Germany.
A new video shows what a traveler aboard Mercury's MESSENGER spacecraft would see as they zipped over the planet's north polar region.
Larry Crumpler updates us on the Opportunity rover, which now holds the distance record for a rover on another planet and is about to climb up its highest crater rim segment yet.
Seven science instruments will help the Mars 2020 rover identify biosignatures and understand the history of the rocks it encounters on the surface of the red planet.
NASA Announces the Suite of Science Instruments on its Next Mars Rover Today
Will search for signs of past life

Today marks the unveiling of the suite of science instruments that will travel to Mars to look for signs of past life and help determine samples to store for possible return to Earth. The next rover mission will launch in 2020.
A journey of nearly a decade is almost over. Rosetta is making its final approach to comet 67P/Churyumov-Gerasimenko, and the comet's strange shape is beginning to come into focus. As of today, the spacecraft is only 2000 kilometers away from the comet, and 8 days away from arrival.
For the last four weeks, the name of the game for Curiosity has been driving. But these weeks of driving have been more challenging than they used to be.
Despite the fact that it hasn't moved for 6 months, the plucky Yutu rover on the Moon is still alive. Its signal is periodically detected by amateur radio astronomers, most recently on July 19. A story posted today by the Chinese state news agency offers a new hypothesis to explain the failure of the rover's mobility systems.
Technically, Pluto science observations don't begin for New Horizons until 2015, but the spacecraft will take a series of photos of Pluto and Charon from July 20 to 27 as it begins the first of four optical navigation campaigns.
I could not wait to post these amazing new images of comet Churymov-Gerasimenko from Rosetta. The nucleus of the comet is clearly a contact binary -- two smaller (and unequally sized object) in close contact.
Opportunity got off to a bumpy start in June, but the Mars Exploration Rover (MER) mission pressed on, continuing the exploration of Murray Ridge at the western rim of Endeavour Crater.
On Monday JPL put out a press release marking one year since Curiosity landed -- one Mars year, that is! There was a new version of the Kimberley self-portrait, and a video update on wheel wear testing. While we've been celebrating on Earth, Curiosity has been driving, driving, driving, on a new "safe transit route" taking her southward toward the black sand dunes ringing Mount Sharp.
The two spacecraft currently orbiting the two innermost planets are both flying low in their orbits in the final phases of their missions. MESSENGER just performed a rocket burn to raise its orbit slightly, while Venus Express did the opposite.
NASA selects Planetary Society LIFE Proposal
To study flight of LIFE experiment on ARM (Asteroid Redirect Mission)
NASA has selected a Planetary Society proposal to study accommodation of the Society’s LIFE (Living Interplanetary Flight Experiment) biomodule on NASA’s Asteroid Redirect Mission (ARM).

Rosetta has now completed its three largest rendezvous burns as it approaches ever closer to comet 67P/Churyumov-Gerasimenko. Beginning on July 2, Rosetta will now conduct weekly burns, through August 6. Meanwhile, the cometary activity of April and May has quieted again, leaving the comet looking smaller than it did before.
