Rosetta and Philae Capture First Detailed Magnetic Measurements of a Comet Nucleus

Comet 67P/C-G’s activity! This stunning montage of 18 images from Rosetta’s navcam camera shows off the comet’s activity from many different angles. It covers the time period between 31 January (top left) and 25 March (bottom right), 2015, when the spacecraft was at distances of about 30 to 100 km from the comet. […]

Rosetta Team Completely Rethinking Comet Close Encounter Strategy

This single frame Rosetta navigation camera image was taken from a distance of 77.8 km from the centre of Comet 67P/Churyumov-Gerasimenko on 22 March 2015. The image has a resolution of 6.6 m/pixel and measures 6 x 6 km. The image is cropped and processed to bring out the details of the comet’s […]

Rosetta’s Valentine’s Day Flyby Encounter Produces Stunning Comet Close-Ups

Backside view of Comet 67P/Churyumov-Gerasimenko Four image mosaic of Comet 67P/Churyumov-Gerasimenko comprising images taken on 14 February 2015 at 10:15 GMT just prior to closest approach from a distance of 12.6 km from the comet centre (about 10.6 km from the surface). For the comet centre distance, the image scale is 1.1 m/pixel. […]

Curiosity Spied From Orbit by Mountain Drilling Base Where Ancient Water Flowed on Mars

Curiosity on Mars from Above and Below NASA’s Curiosity rover conducts fifth Martian sample drilling campaign at “Mojave 2” rock target in this composite photo mosaic from Sols 864 to 889. The mosaic shows the robotic arm deployed on Sol 889, Feb. 5, 2015 to the “Pink Cliffs” portion of the “Pahrump Hills” […]

Rosetta Captures Spectacular Comet Jets Blasting Away Ahead of Valentine’s Day Encounter

Comet 67P/Churyumov-Gerasimenko belching gas and dust This four-image mosaic comprises images taken from a distance of 28.7 km from the centre of Comet 67P/Churyumov-Gerasimenko on 3 February and released on 9 February 2015. The image resolution is 2.4 m/pixel and the individual 1024 x 1024 frames measure 2.5 km across. The mosaic measures […]

Rosetta Reveals Cracked Comet Covered With Dust and Spewing Pits

Comet 67P/Churyumov–Gerasimenko regional maps The 19 regions identified on Comet 67P/Churyumov–Gerasimenko are separated by distinct geomorphological boundaries. Following the ancient Egyptian theme of the Rosetta mission, they are named for Egyptian deities. Credit: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA
