Curiosity is at a turning point in its mission to Mount Sharp, both literally and figuratively. Having drilled at three sample sites in 7 weeks, the rover took a left turn, changing its trajectory from a generally westward driving path to a southward one. It is now poised to cross the Bagnold dune field at Murray buttes.

Opportunity spent the first half of May digging into an outcrop, taking dozens of panoramic images from her site on the south wall of Marathon Valley at Endeavour Crater’s western rim, and basking in the Martian spring weather.

Lockheed Martin proposed a system to send humans to orbit Mars in the year 2028—a concept that shares many core values with The Planetary Society's report, Humans Orbiting Mars, we released last year.

Curiosity has drilled into Mars for the 10th time at a site named Lubango, on sol 1320 (April 23, 2016). Lubango is in a bright-toned halo around a crack in the Stimson sandstone unit on the western edge of the Naukluft Plateau.

Curiosity has driven onward from Namib dune across a highstanding unit of rock called the Naukluft Plateau. Despite some frustrating sols lost to a short circuit in the RTG and DSN troubles, the rover has made progress, and performed lots of 3D imaging of weirdly wind-eroded rocks.

Ever wanted to stand on Mars and watch a sunset? Unfortunately for many of us, it will never be something that we get to experience in person. But thanks to our robotic emissaries on Mars, and some careful processing of images from NASA's Planetary Data System, we can get a sense of what it’s like.
