ESA's Rosetta comet chaser will swing by Earth on 13 November to pick up orbital energy and begin the final leg of its 10-year journey to the outer Solar System. Several observations of the Earth-Moon system are planned before the spacecraft heads out to study comet 67/P Churyumov-Gerasimenko.
This will be the third Earth swingby, the last of Rosetta's four planetary gravity assists. Closest approach to Earth is expected at 08:45 CET. The swingby will provide exactly the boost Rosetta needs to continue into the outer Solar System. The craft is scheduled for a close encounter with asteroid 21 Lutetia in July next year.
