Cambridge, MA -- Smithsonian astronomers watched as the "Impactor" probe from NASA's Deep Impact spacecraft hit Comet Tempel 1 earlier this week. They monitored the impact using the ground-based Submillimeter Array (SMA) in Hawaii and NASA's orbiting Submillimeter Wave Astronomy Satellite (SWAS). Results are still coming in, but so far the scientists report seeing only weak emission from water vapor and a host of other gases that were expected to erupt from the impact site. The most...

JPL -- NASA's Deep Impact spacecraft continues to sail through its final checkout, as it hurtles toward comet Tempel 1. Impact with the comet is scheduled for 1:52 a.m. EDT, July 4 (10:52 p.m. PDT, July 3). "The time of comet encounter is near and the major mission milestones are getting closer and closer together," said Rick Grammier, Deep Impact project manager at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "After all the years of design, training and simulations, we are where we...

Cambridge, MA -- The Submillimeter Wave Astronomy Satellite (SWAS) has been asleep on orbit for the past 11 months. SWAS operators placed it into hibernation after a highly successful 5.5-year mission highlighted by the discovery of a swarm of comets evaporating around an aging red giant star. Now, they have awakened SWAS again for the first-ever opportunity to study a comet on a collision course with a U.S. space probe. "We knew there was life left in SWAS," said SWAS Principal Investigator...
