Philae spotted on the surface of comet Churyumov-Gerasimenko

Posted by Emily Lakdawalla on 2016/09/06 02:27 CDT | 1 comments

Ever since its landing, Philae has been elusive. It went silent just three days later and never returned any more science data, though it made brief contact with the orbiter last summer. Now, just a month until the planned end of the Rosetta mission, the orbiter has finally located the lander in a stunning high-resolution view of the surface.

JunoCam raw data from the Juno approach movie

Posted by Emily Lakdawalla on 2016/08/09 03:03 CDT | 1 comments

As it approached Jupiter from June 12 to 29, JunoCam captured an animation of the major moons orbiting the planet. The mission released a processed version of the animation on the day of orbit insertion, but took a few weeks to release the raw image data. I've prepared a page hosting all the raw data, and share a few processed versions.
