Curiosity activities over sols 465 to 487 included monitoring the condition of the wheels; a flight software upgrade; and dumping the Cumberland drill sample. Curiosity put approximately 200 meters on the odometer during this period.
Today there was a lengthy press briefing by several members of the Chang'e 3 science team. A complete transcript was posted in Chinese. I have run it through two machine translators and found it to be quite informative, not just about the mission but also about attitudes about Chinese space exploration and foreign cooperation. I also have a cool fan-produced video to share.
Transmitting images all the way down, China's Chang'e 3 lander successfully arrived on the lunar surface at 13:11:18 -- half an hour before the scheduled landing time. Rover deploy is set for a few hours later.
According to numerous Chinese news reports, Chang'e 3's landing on the Moon is now scheduled to begin at 21:40 Beijing time on December 14, which is 13:40 UT or 05:40 PT. That's about two hours earlier than previously stated.
Gliding smoothly through the main asteroid belt between Mars and Jupiter, Dawn continues to make good progress on its ambitious mission of exploration. It is patiently but persistently pursuing Ceres, the second destination on its interplanetary itinerary.

Chang'e 3 is just about to land on the Moon, and the LADEE orbiter has begun a new science mission there, while Lunar Reconnaissance Orbiter is still producing amazing images.
Although winter took hold at Endeavour Crater in November, Opportunity pressed on, climbing up Murray Ridge and driving into a clay mineral hunting ground as the Mars Exploration Rovers mission cruised another month closer to celebrating its 10th Earth year of surface operations with myriad events throughout January 2014.
On December 1 at 17:30 UTC, Chang'e 3 launched atop a Long March 3B rocket on a direct lunar transfer trajectory. It is scheduled to enter orbit December 6 and land December 14. The rocket was equipped with cameras that recorded thrilling video of the launch and final departure of the probe.
Today I am delighted to welcome India into the ranks of interplanetary travelers: Mars Orbiter Mission has successfully propelled itself onto an interplanetary trajectory, departing Earth forever and setting sail for Mars. Congratulations to India, to the Indian Space Research Organisation, to the mission's scientists and engineers, and to the people of India.
Today is the day when India's Mars Orbiter Mission will fire its rocket to depart Earth and begin its 300-day journey to Mars. The rocket burn begins on December 1 at 00:49 IST (today at 19:19 UT / 11:19 PT).
Yesterday the Chinese space agency held a press briefing about the Chang'e 3 lunar lander. They announced that the rover has been named Yutu (or "Jade Rabbit," a legendary companion of the goddess Chang'e). Although it will land during the LADEE mission, it will not harm LADEE's goals -- quite the opposite, in fact.
An electrical problem frustrated progress on the Curiosity mission this week, but the problem is now understood and the rover back to work.
On sol 3485 Opportunity pulled up next to a large outcrop here on the rim of Endeavour crater. The outcrop appears to be impact breccias like those we saw a few sols ago lower down on the ridge. But the texture of the rocks is somewhat different.
Two spacecraft launched for Mars this month: Mars Orbiter Mission on November 5, and MAVEN on November 18. MAVEN is now on an interplanetary trajectory, while Mars Orbiter Mission is still in Earth orbit and will not depart for Mars until the end of the month. A lot of people are asking me: why the difference? Here's your answer, with input from Dave Doody.
