A new budget submission from the White House would continue record-high funding for planetary science, but proposes deep cuts to 2 productive Mars missions and defers funding for deep space telescope dedicated to finding hazardous near-Earth objects.
What happens when you print a map of Mars the size of a basketball court?
ExoMars Trace Gas Orbiter arrives on October 19, and it will deliver the Schiaparelli lander to its brief life on the Martian surface. Juno's headed into its science orbit, MOM has released science data, and New Horizons will finally finish downlinking Pluto flyby data.
Mars Odyssey has been in space for 15 years. It flies in a special
What's going on with our robotic planetary missions? In February I count more than 20 planetary spacecraft exploring six targets beyond Earth or cruising to new destinations.
It's been two weeks since comet Siding Spring passed close by Mars, and six of the seven Mars spacecraft have now checked in with quick looks at their images of the encounter. I round up all the results.
All seven Mars spacecraft are doing perfectly fine after comet Siding Spring's close encounter with Mars.
Senior review recommends continuing all major planetary exploration missions, but not without some changes.
Now that we have reasonable confidence that our Mars orbiters will be safe from the close passage of comet Siding Spring, we are free to be excited about the opportunity that the encounter represents. At a community workshop on August 11, representatives from Mars missions shared their plans for great comet science.
With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.
The Martian Geologic Time Scale is a lot more complicated than the Moon's.
Twelve years on, Mars Odyssey just keeps sending great images.

Welcome to the monthly roundup of our solar system's envoy of electronic explorers! All eyes are on Curiosity as it approaches Mars this weekend. Who will lend support at the Red Planet?
Welcome to my monthly roundup of the activities of our intrepid robotic emissaries across the solar system! Curiosity is about to land; Opportunity has rolled through sol 3000; Odyssey is back online, having switched to a spare reaction wheel; Dawn is now in High-Altitude Mapping Orbit 2; and Cassini is taking advantage of its newly inclined orbit to get spectacular series of images of Saturn's rings.
There was good news and bad news in this morning's press briefing about Curiosity rover's upcoming landing on Mars, just eight weeks from now. First, the good news: the landing ellipse has shrunk. The bad news: there's a contamination problem with the drill, and the Odyssey orbiter is in safe mode.
Jason Davis put together this neat summary of the checkered history of Mars exploration.
