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.

Earlier this week, NASA announced that it was cutting off ties with Russia, except for activities relating to the ISS. This raised questions about Russian participation on NASA's science missions, particularly the Russian experiment on the Curiosity rover.

A 0.81m telescope in northern Italy is well on its way to being wide eyed and shiny thanks to a 2013 Planetary Society Shoemaker NEO Grant, which will enable it to make better near Earth object observations to help protect our planet from asteroid impact.

At the Lunar and Planetary Science Conference, Jennifer Scully discussed possible water-carved gullies in an unusual location: within craters on Vesta. Water-carved gullies on Mars I can accept; but on an airless lumpy body? I was intrigued.

Simon Kattenhorn and Louise Prockter may finally have found subduction zones on Europa, which would it the only other place in the solar system besides Earth that is known to have active plate tectonics.
