Europe's Experimental Spaceplane Completes Successful Test Flight
The IXV spaceplane, designed to demonstrate reentry technologies, splashed down in the Pacific Ocean this morning after a successful, 100-minute test flight.
Rosetta shifts from sedate circular orbits to swooping flybys
For the period of time before and after the Philae landing, Rosetta was able to orbit the comet close enough that it was in gravitationally bound orbits, circling the comet's center of gravity. As the comet's activity increases, the spacecraft has to spend most of its time farther away, performing occasional close flybys. The first of these is at 6 kilometers, on February 14.
A new mission for Akatsuki, and status updates for Hayabusa2 and Chang'e
Brief updates on four ongoing missions: JAXA's Akatsuki and Hayabusa2, and China's Chang'e 3 and Chang'e 5 test vehicle. JAXA has articulated the new science plan for Akatsuki. Hayabusa2's ion engines have checked out successfully. The Yutu rover is still alive on the Moon, and Chang'e 5 test vehicle has successfully tested crucial rendezvous operations in lunar orbit.
Planet Formation and the Origin of Life
To understand the possible distribution of life in the Universe it is important to study planet formation and evolution. These processes are recorded in the chemistry and mineralogy of asteroids and comets, and in the geology of ancient planetary surfaces in our Solar System.
Two Days, Two Launches and Three Landings
Within a two-day span, two rocket launches and three ocean landings are scheduled—one of which involves an autonomous spaceport drone ship.
Rising Stargirls: Girls of All Colors Learning, Exploring, and Discovering
Aomawa Shields discusses a workshop she designed for underrepresented girls in grades 6-8 that will teach key concepts in astronomy, highlighting what is beyond what we can see with our eyes, using nontraditional methods.
Ceres coming into focus
The Dawn mission released new images of Ceres yesterday, taken on February 4, when Dawn had approached to within 145,000 kilometers. More details are coming into view, and they're fascinating. For one thing, there's not just one white spot any more: there are several.
FOIA Request Sheds Light on NASA Mission Extension Process
A FOIA request offers insight into NASA's planetary science extended mission review process, which seems, at best, confusing, and at worst—with adjectival ratings like “Very Good/Good”—arbitrary.

Mars Exploration Rovers Update: Opportunity Completes 11th Year of Surface Operations!
On January 24th, something wonderful happened on Mars. Opportunity completed her 11th year of exploring the surface of the Red Planet! The veteran rover couldn't exactly go to Disneyland to celebrate this amazing achievement, so she did what she loves to do – roved on.
It's Official: We're On the Way to Europa
NASA's 2016 budget request increases the space agency's budget by $519 million, starts a new mission to Europa, increases funds to Commercial Crew, and threatens some long-running planetary missions.

Talking to Pluto is hard! Why it takes so long to get data back from New Horizons
As I write this post, New Horizons is nearing the end of a weeklong optical navigation campaign. The last optical navigation images in the weeklong series will be taken tomorrow, but it will likely take two weeks or more for all the data to get to Earth. Two weeks! Why does it take so long?
