Last visit home for ESAs comet chaser
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 EarthMoon 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 Rosettas 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.
