Updates on China's lunar missions
It's official: China plans to send a lander mission to the lunar farside. A relay satellite will launch to the Earth-Moon L2 point in June of 2018, and a lander will follow at the end of 2018. The landing site may be within the south pole-Aitken basin.
JunoCam cruise data, and a look ahead to Jupiter
Juno is now fewer than six months and 100 million kilometers away from Jupiter, and the Juno team is busily preparing for the arrival. Amateur astronomers are supporting them by taking lots of Jupiter photos.
Mars Exploration Rovers Update: Opportunity Finishes Another Record Year, Approaches 12th Anniversary
Perched on the southern wall of Marathon Valley at Endeavour Crater, Opportunity braved temperatures descending well below -100° F in December to work the winter science campaign and home in on the remnants of ancient clays.
Curiosity update, sols 1166-1217: First reconnaissance of Bagnold dunes
In the six weeks since my last detailed Curiosity update, the rover has driven to, on, and around a couple of active barchan sand dunes on Mars. They are now searching for a site to scoop and sample sand on the western edge of Namib dune.
Capturing the Rhythm of Space: Insights from 47th DPS Meeting
The Division of Planetary Science (DPS) Meeting saw many exciting scientific discussions spanning the range of processes on different planetary bodies, as well as their replication in the laboratory and in models.
A Lander for NASA’s Europa Mission
While there’s at least eight years until it launches, this has been a pivotal year for developing NASA’s Europa mission.
Dawn Journal: Science on Ceres
The Dawn mission is developing humankind’s most intimate portrait ever of a dwarf planet. Mission Director and Chief Engineer Marc Rayman returns with his monthly update on the mission's progress.
Two epic photos of Earth -- but which one is truer?
Two images of Earth taken from different spacecraft at the same time illustrate differences in
ExoMars Trace Gas Orbiter and Schiaparelli lander travel safely to Baikonur
Europe's second mission to Mars has begun its journey from its birthplace in Cannes to its planned arrival at Mars on October 19. Since December 17 we've been able to watch every step of its journey via Twitter.
Pretty Pictures of the Cosmos: Distant Galaxies
Astrophotographer Adam Block shares stunning his images of far-away spiral galaxies.
InSight's Problems: Possible Impacts
Van Kane details the potential repercussions of the launch delay of InSight Mars lander on the rest of NASA's Discovery mission program.
NASA's Next Mars Mission Delayed for Two Years
A problem with the French space agency's seismometer instrument will delay NASA's InSight Mars lander by two years.
December solstice: Viewing Earth's seasonal shifts from space
It's fun to watch the seasons shift from space, and as of this year we have new ways to do that.
For the first time ever, a Curiosity Mastcam self-portrait from Mars
In a remarkable and wholly unexpected gift to Curiosity fans, the rover has just taken the first-ever color Mastcam self-portrait from Mars.
Pluto updates from AGU and DPS: Pretty pictures from a confusing world
Pluto is reluctant to give up its secrets. Last week at the American Geophysical Union meeting I attended sessions featuring results from the New Horizons mission, and most of the presentations could be summed up thusly: the data sets are terrific, but there are still a lot of Pluto features that have scientists scratching their heads.
Curiosity stories from AGU: The fortuitous find of a puzzling mineral on Mars, and a gap in Gale's history
Yesterday at the American Geophysical Union meeting, the Curiosity science team announced the discovery of a mineral never before found on Mars. The finding was the result of a fortuitous series of events, but as long as Curiosity's instruments continue to function well, it's the kind of discovery that Curiosity should now be able to repeat.
OSIRIS-REx Completes Mechanical Environmental Testing
The OSIRIS-REx team successfully and safely completed sine vibration (sine vibe) testing on the spacecraft prior to the Thanksgiving holiday. The sine vibe tests are designed to verify the system performs as expected after being exposed to flight-like low frequency vibration input.
Worth the wait: First public release of Rosetta science camera images of comet 67P
Finally! It has been a long wait, but so worth it: the Rosetta OSIRIS science camera team has delivered the first pile of data from the rendezvous with comet 67P to ESA's Planetary Science Archive. I have spent a good chunk of the last three days playing with the data, and it's spectacular.
A Rosetta OSIRIS picture of comet 67P that's only hours old
ESA announced today a new website at which the OSIRIS team will now be releasing images on a regular basis -- at least one per week -- and they will be recent. Even better news, all OSIRIS data taken through September 16, 2014 has been handed to ESA and its release is expected next week.
Akatsuki's new orbit, first images, and science plans
JAXA had a press briefing today to confirm the successful arrival of Akatsuki into Venus orbit. It's been a long time coming: today's announcement came twelve years to the day after Japan had to abandon efforts to put Nozomi into Mars orbit. They released lovely images and discussed future plans.
