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.

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.

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.
