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. The […]

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 activity. […]

Comet Debris Causes Significant Navigation Issues During Rosetta’s Latest Close Flyby

This stunning scene was created from two NAVCAM frames acquired at 19.9 km from the comet centre on 28 March. The scale is about 1.7 m/pixel and the image measures 3.1 x 1.7 km. The image has been adjusted for intensity and contrast, and the vignetting has been fixed. Credits: ESA/Rosetta/NAVCAM – CC BY-SA […]
