Larry Crumpler returns with an update on Opportunity's recent activities, and its road ahead.

At Pahrump Hills, Curiosity is becoming the field geologist she was intended to be.
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.
When New Horizons wakes up for the final time on Dec. 6, scientists will spend six weeks preparing for the start of the spacecraft's Pluto encounter.
Emily Lakdawalla gives a status report on Philae from the European Space Operations Centre (ESOC) in Darmstadt.
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.
Philae is "go" for landing. But there has been drama overnight. One of the steps to prepare for landing did not proceed as planned. UPDATE: At 09:03 UTC, the lander separated from the orbiter, beginning a 7-hour descent to the surface of the comet.
It's been a day of calm before the storm here at the European Space Operations Centre in Darmstadt, as we get ready for the big event tomorrow: Philae's hoped-for landing on a comet. The first of four "go-no-go" decisions has been made, and it's a "go." Mission navigators have gotten data back from Rosetta that indicates that the spacecraft is on the correct trajectory to deliver Philae to the comet.
I'm reporting live from the press room at the European Space Operations Centre in Darmstadt, Germany. There's little news on Philae yet except that its status is good. Meanwhile, Rosetta scientists presented their first early comet results at the Division for Planetary Sciences meeting in Tucson, Arizona, which I watched from afar using Twitter.
Earth's first-ever landing on a comet is a week away. On November 12 at 8:35 UT, Philae will separate from Rosetta. Seven hours later, it will arrive at the surface of the comet. Hopefully, Philae will survive the landing, and begin to return data.

As winds whirled and converged to the west of Endeavour Crater, Opportunity's power dropped dramatically in October, but the Mars Exploration Rover (MER) pressed on. By month's end, the robot field geologist had completed her assignments – including capturing the first close-in shot of a comet from the surface of the Red Planet – and was roving onward through the darkness, driving the mission into the 130th month of what started out more than 10-and-a-half years ago to be a 3-month tour.
The Chang'e 5 test vehicle service module did not follow the sample return capsule into Earth's atmosphere. Instead, it successfully performed a divert maneuver, and is now on its way to the Earth-Moon L2 point
The Chang'e 5 test vehicle landed successfully in Inner Mongolia today after an 8-day mission. It demonstrated technology that China plans to use for automated sample return by the Chang'e 5 mission in 2017.
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.
