On Monday, May 3rd, he assumed the role of 14th NASA Administrator during a ceremony where he was given the oath of office.Continue reading “It’s Official, Astronaut Bill Nelson is NASA’s new Administrator”
WOW! We’re really getting to the good stuff now! This is no computer-generated shape model, this is the real deal: the double-lobed nucleus of Comet 67P/C-G, as imaged by Rosetta’s OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) narrow-angle camera on Tuesday, July 29. At the time just about a week away from making its arrival, ESA’s spacecraft was 1,950 km (1,211 miles) from the comet when this image was taken. (That’s about the distance between Providence, Rhode Island and Miami, Florida… that’s one fancy zoom lens, Rosetta!)
This latest image reveals some actual surface features of the 4-km-wide comet, from a few troughs and mounds to the previously-noted bright band around the “neck” connecting the two lobes. The resolution in the July 29 OSIRIS image is 37 meters per pixel.
Since Rosetta is quickly closing the gap between itself and the comet we can only expect better images to come in the days ahead, so stay tuned — this is going to be an exciting August!

Take a ride on the Mercury express and see what MESSENGER sees in these two new videos! Each made from over 280 Narrow-Angle Camera (NAC) images taken at intervals of four seconds, the videos give us a first-class seat on a flight over some of the rugged, sun-scorched surfaces on Mercury’s southern hemisphere.
Check out the second video below:
