Yutu rover drives around Chang’e-3 lander – from Above And Below
Composite view shows China’s Yutu rover and tracks driving in clockwise direction around Chang’e-3 lander from Above And Below (orbit and surface). The Chang’e-3 timelapse lander color panorama (bottom) and orbital view (top) from NASA’s LRO orbiter shows Yutu rover after it drove down the ramp to the moon’s surface and began driving around the landers right side and heading south on Lunar Day 1. It then moved northwest during Lunar Day 2. Arrows show Yutu’s positions over time. Credit: CNSA/NASA/Ken Kremer/Marco Di Lorenzo/Mark Robinson
The powerful telescopic camera aboard NASA’s Lunar Reconnaissance Orbiter (LRO) has captured spectacular new images detailing the traverse of China’s Yutu moon rover around the landing site during its first two months exploring the Moon’s pockmarked grey terrain.
The newly released high resolution LRO images even show Yutu’s tracks cutting into the lunar surface as the world famous Chinese robot drove in a clockwise direction around the Chang’e-3 lander that delivered it to the ground in mid-December 2013.
Sunday is going to be a once-in-a-generation moment. For those of us who were too young to remember the original Cosmos (writer puts hand up) or those who are eager to see the classic 1980 Carl Sagan series updated with discoveries since then, we’re all in luck. A new series starring astronomer Neil deGrasse Tyson is premiering on Fox.
NASA hosted a sneak preview of the series at several NASA centers, and the early reviews on Twitter indicated a heck of a lot of excited people in the audience. In the video above, you can watch the Q&A with the main players after the premiere concluded.
A Saturn-mass planet might be lurking in the debris surrounding Beta Pictoris, new measurements of a debris field around the star shown. If this could be proven, this would be the second planet found around that star.
The planet would be sheparding a giant swarm of comets (some in front and some trailing behind the planet) that are smacking into each other as often as every five minutes, new observations with the Atacama Large Millimeter/submillimeter Array (ALMA) show. This is the leading explanation for a cloud of carbon monoxide gas visible in the array.

A Louisiana sinkhole the size of 19 American football fields shifted sideways in radar measurements before its collapse and resulting evacuations in 2012, a study reveals.
The implication is that if certain types of radar measurements are collected regularly from above, it is possible to see some sinkholes before they collapse. The researchers added, however, that their discovery was “serendipitous” and there are no plans to immediately use a NASA robotic Gulfstream plane used for the study to fly over spots that could be vulnerable to sinkholes.
Data showed the ground near Bayou Corne moving horizontally up to 10.2 inches (26 centimeters) toward where the sinkhole appeared suddenly in August 2012. The hole started out at about 2 acres of size (1 hectare) — an area smaller than the initial ground movements — and now measures about 25 acres (10 hectares).
