CASSINI spacecraft & exoplanets !!

Incredible : Shocked

« …Scientists actually want to use the occasion to test the VIMS instrument's capacity for observing planets outside our solar system.
"Interest in infrared investigations of extrasolar planets has exploded in the years since Cassini launched, so we had no idea at the time that we'd ask VIMS to learn this new kind of trick," said Phil Nicholson, the VIMS team member based at Cornell University, Ithaca, N.Y., who is overseeing the transit observations. "But VIMS has worked so well at Saturn so far that we can start thinking about other things it can do."
VIMS will be able to complement exoplanet studies by space telescopes such as NASA's Hubble and Spitzer space telescopes. VIMS scientists are particularly interested in investigating atmospheric data - such as signatures of methane -- from far-off star systems in near-infrared wavelengths.
The pointing has to be very accurate to get one of those extrasolar planets in VIMS's viewfinder, but the instrument has had lots of practice pointing at other stars. Earlier this year, VIMS obtained its first successful observation of a transit by the exoplanet HD 189733b. Scientists want to improve these observations by reducing the amount of noise in the signal… »

Nice one this, certainly there are interesting things you can do with spacecraft spread throughout the solar system. IIRC there was a microlensing detection that benefitted from space-based results a while back.
