A set of photos released by Mars Orbiter Mission last week completes the set of Mars spacecraft observations of the comet. Now we wait for science results!
This morning ESA released a set of images of the Philae lander taken by the Rosetta orbiter during -- and after -- the lander's first touchdown. The images contain evidence for the spot Philae first touched the comet, and a crucial photo of Philae's position several minutes into its first long bounce.
I'm just getting up to speed on the news from overnight, which is mostly good: Philae remained in contact with the orbiter (which means the CONSERT radar sounding experiment was working), and it's sitting stably on the surface, although it's not anchored in any way. And they released the first ÇIVA image from the ground!
The landing happened on time just after 16:02 UT today! Philae mission manager Stephan Ulamec said: "Philae is talking to us! The first thing he told us was the harpoons have been fired and rewound. We are sitting on the surface." Those words later turned out not to be true; but we do know at least that Philae survived the landing and is returning good data.
Here it is. We knew hours ago that Philae separation happened, but there's nothing like seeing a photo, seeing Philae's mothership receding into the distance.
It's been two weeks since comet Siding Spring passed close by Mars, and six of the seven Mars spacecraft have now checked in with quick looks at their images of the encounter. I round up all the results.
On October 27, JAXA provided media with an opportunity to view the Hayabusa 2 spacecraft at the Tanegashima space center, where it's making final preparations for launch. Koumei Shibata was there, and took several photos. And artist Go Miyazaki has shared several terrific new renderings of the spacecraft in flight.
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
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.
The European satellite Herschel acquired images of Comet Siding Spring before its death in 2013 — thanks to an observing proposal from an amateur astronomer!
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.
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.
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.
It's now been two years since Dawn wrapped up its work at the second-largest asteroid. What else did we get from the Vesta encounter besides great photos? Recently, I asked Dawn's deputy project scientist, Carol Raymond, for help in summarizing a few of the big things Dawn taught us.
