The House of Representatives held a hearing today to discuss their proposed NASA authorization bill, which would fund Planetary Science, cut Earth Science, forbid asteroid retrieval, and command NASA to pursue a path to Mars via the Moon.
ESA celebrated the tenth anniversary of Mars Express' launch with a several-day science meeting during which they issued lots of press releases and numerous spectacular photos. My favorite of them all is this enormous image of Kasei Valles on Mars.
