On November 13, 2009, at 8:45 AM CET, ESA’s comet chaser Rosetta swung by Earth. Rosetta passed just South of the Indonesian island of Java at an altitude of 2481 km. Its speed relative to Earth was 13.34 km/s. The maneuver provided a boost of 3.6 km/s.

Rosetta’s OSIRIS (Optical Spectroscopic and Infrared Remote Imaging System) narrow-angle camera was used to image the Earth once every hour for 24 hours.

Rosetta will meet asteroid 21 Lutetia in 2010. The final destination of Rosetta is the comet 67P/Churyumov-Gerasimenko, which the spacecraft will reach in 2014. Rosetta will deploy a lander to the surface of the comet, and will also orbit the nucleus of the comet and fly alongside as it heads towards the inner Solar System. Most of the time, the probe will hibernate with the majority of its systems shut down in order to optimize the power consumption.
