Make a NAVCAM mosaic

Today’s four-image NAVCAM montage comprises images taken on 31 August from a distance of 61 km from comet 67P/C-G. NAVCAM image sequences are now being taken as small 2 x 2 rasters, such that roughly one quarter...

Determining the mass of comet 67P/C-G

Rosetta is equipped with a range of instruments to analyse comet 67P/Churyumov-Gerasimenko, but the spacecraft itself can also be used to determine properties of the comet. As the spacecraft passes close to comet 67P/C-G, it is pulled...

Landing site selection: the race is on

Rosetta has been at comet 67P/Churyumov-Gerasimenko for two weeks, collecting critical data that are now being used to identify candidate landing sites for Philae. This coming weekend up to five candidate landing sites will be proposed for further...

What’s up with Rosetta?

Incredible precision: the orbit determination done after the 13 August burn found that Rosetta’s thrusters had over-performed by just 0.2%!
