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 […]

Rosetta Makes First Detection of Cometary Molecular Nitrogen, Seeks Signals From Philae Lander

Rosetta has made the first detection of molecular nitrogen at a comet. The results provide clues about the temperature environment in which Comet 67P/Churyumov–Gerasimenko formed. Credit: ESA/ATG medialab; comet: ESA/Rosetta/NavCam – CC BY-SA IGO 3.0

Rosetta, humankind’s first spacecraft to orbit a comet, has now made the first detection of molecular nitrogen (N2) at […]

Could it be possible that a lander the size of a washing machine, thought to be lost nearly four months ago following its passing into shadow, […]

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. In […]

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 4.2 […]

Rosetta Reveals Cracked Comet Covered With Dust and Spewing Pits
