The Chang'e 5 test vehicle's short mission is more than half over. It has rounded the far side of the Moon and is on its way back to Earth for a planned October 31 test of lunar sample return technology. It's not a science mission -- it's an engineering mission -- but it has managed to return an absolutely iconic photo of its distant home, seen across the very unfamiliar far side of the Moon.
Society Board Member John Logsdon describes how the decisions made by Richard Nixon in late 1969 and early 1970 effectively ended human exploration beyond Earth orbit for the indefinite future.
I have been horribly behind in posting images from Rosetta's exploration of comet 67P/Churyumov-Gerasimenko, and that's a shame, because the spacecraft has lately been exploring the comet from a range of only 10 kilometers. From that range, the NavCam gets sub-meter resolution, and we're seeing a menagerie of odd surface features
What do “light” and “dark” mean for an object like Comet 67P/C-G? Here are some details on how Rosetta's NAVCAM images are taken and displayed to make a wide range of surface features possible.
A team of scientists at the University of Arizona plan to digitize 87,000 vintage images from the surface of the moon, of which less than two percent have ever been seen.
At the Geological Society of America conference this week, Curiosity scientists dug into the geology of Gale crater and shared puzzling results about the nature of the rocks that the rover has found there.
China launched to the Moon today! The spacecraft will have a brief, 8-day mission, out to the Moon and back. It is an engineering test for the technology that the future Chang'e 5 sample return mission will need to return its precious samples to Earth.
The European satellite Herschel acquired images of Comet Siding Spring before its death in 2013 — thanks to an observing proposal from an amateur astronomer!
One of the tricky parts of launching humans into space is deciding what to do if something goes wrong. And that's where Orion's Launch Abort System comes in.
All seven Mars spacecraft are doing perfectly fine after comet Siding Spring's close encounter with Mars.
The nucleus of comet Siding Spring passes close by Mars on Sunday, October 19, at 18:27 UTC. Here are links to webcasts and websites that should have updates throughout the encounter.
Curiosity spent a total of four weeks at Confidence Hills, feeding samples to SAM and CheMin several times. On two weekends during this period, the rover's activities were interrupted by faults with the robotic arm. Curiosity drove away from Confidence Hills on sol 780, and is ready to observe comet Siding Spring over the weekend.
The Planetary Society's LightSail-A spacecraft is close to completing a final series of tests that pave the way for a possible 2015 test flight. But as deadlines loom, a new problem has sent the team scrambling to make a quick repair.
What a huge relief: there is finally a place for New Horizons to visit beyond Pluto. A team of researchers led by John Spencer has discovered three possible targets, all in the Cold Classical part of the Kuiper belt. One is particularly easy to reach. New Horizons would fly past the 30-45-kilometer object in January 2019.
Opportunity will become a comet flyby mission beginning in mid-October. The comet Siding Spring will zoom past Mars at a distance of about 135,000 km on October 19.
Today the Mars Orbiter Mission released a nice four-image animation of teeny dark Phobos crossing Mars' huge orange disk. Mars Orbiter Mission joins a long line of Mars missions that have produced images of Mars and Phobos together.

On October 19, 2014, Comet Siding Spring will fly very close to Mars. Here’s a 5 minute video introduction to get you up to speed on this planetary near miss, and some suggestions on how to find out more now, during, and after the encounter.
Watch as our enormous moon -- a quarter the diameter of the planet -- just winks out as it passes into Earth's long shadow, in an animation captured from more than 100 million kilometers away.
