The final phase of Curiosity's landing on Mars involves the "skycrane maneuver" and will leave the rover on its wheels ready for its mission on Mars to begin.
How Curiosity Will Land on Mars, Part 2: Descent
When people first hear about how Curiosity will land on Mars, their first question always is: are they nuts? This is the second in a multi-part series describing how -- and why -- Curiosity will land this way, in excruciating detail.

This Cosmoquest Science Hangout featured Ravi Prakash, Curiosity Entry, Descent, and Landing Systems Engineer. He explained how Curiosity will land on Mars, and why they've changed things since Spirit and Opportunity landed.
It was just a coincidence, but a cool one, that I got a chance to visit the Mojave Spaceport so soon after the dramatic "New Space" success of the launch and Space Station docking of SpaceX's Falcon 9 and Dragon. My host was Will Pomerantz. Bill Nye, Mat Kaplan, and I visited The Spaceship Company and Scaled Composites, where they are building the next SpaceShipTwo and WhiteKnightTwo craft.
Last week, India launched RISAT 1, a new Earth-observing satellite. How does its synthetic aperture radar compare to that of Envisat, which has fallen silent?
Do planets circle our closest stellar neighbors, the system loved by science fiction: Alpha Centauri? We don’t know. But, Debra Fischer, Julien Spronck, and their colleagues at Yale University, in part with Planetary Society support, are trying to find out.
With the latest piece of the puzzle just published in a scientific journal, a solar system mystery that has perplexed people for more than 20 years has been solved, truly thanks to the support of Planetary Society members.

A classified U.S. military satellite recently launched into an orbital inclination of 123 degrees. What makes this trajectory so unique? Pondering the answer affords the opportunity to learn some deceptively tricky concepts about the nature of all spacecraft orbits.

Yesterday I was treated to a little tour (little, because it's a little building) of Honeybee Robotics' office here in Pasadena. They were putting on a show for a state visit by the new NASA Chief Technology Officer Mason Peck, and had invited media. I was one of only two media who showed up, and I have to say that people who stayed away missed a cool show. Honeybee is developing some great technology for future space missions for Earth, Mars, and beyond.

Maybe it's because I was a kid during the Cold War; I always assume that information about anything nuclear only comes out on that "need-to-know basis."

JAXA's solar sail demonstration craft IKAROS is still puttering along, 17 months after it launched, and its controllers back on Earth keep coming up with new things to try with it. I'm pretty amazed by the most recent trick: reversing its spin direction. This may not sound like a big deal, but it is, especially for IKAROS.
