Rosetta Set to Watch Deep Impact
(Jun 20, 2005) When NASA's Deep Impact spacecraft smashes into Comet Tempel 1 in about 2 weeks, every instrument on Earth and in space will be watching carefully. One spacecraft, the European Space Agency's Rosetta, was built to visit a different comet, so it has a suite of instruments designed for this very job. Rosetta will be 80 million km (50 million miles) away from the comet when it collides with Deep Impact, and will watch the resulting puff of debris in various wavelengths.
