Rosetta to fly by asteroid Lutetia
Washington, July 10 (ANI): ESA's Rosetta spacecraft will make its closest approach to asteroid Lutetia today (1544GMT) as it heads towards comet 67P/Churyumov-Gerasimenko for a 2014 rendezvous.
The NASA instruments aboard Rosetta will record the first close-up image of a metal asteroid. They will also make measurements to help scientists derive the mass of the object, understand the properties of the asteroid's surface crust, record the solar wind in the vicinity and look for evidence of an atmosphere. The spacecraft will pass the asteroid at a minimum distance of 3,160 kilometres and at a velocity of 15 kilometres per second.
Claudia Alexander, project scientist for the U.S. role in the Rosetta mission, from NASA's Jet Propulsion Laboratory in Pasadena, Calif., said: "Little is known about asteroid Lutetia other than it is about 100 kilometres (62 miles) wide. Allowing Rosetta's suite of science instruments to focus on this target of opportunity should greatly expand our knowledge of this huge space rock, while at the same time giving the mission's science instruments a real out-of-this-world workout."
Previous images of Lutetia were taken by ground-based telescopes and show only hints of the asteroid's shape. Lutetia will be the second asteroid to receive the full attention of Rosetta and its instruments. The spacecraft previously flew within 800 kilometres of asteroid Steins in September of 2008. The Lutetia flyby is the final scientific milestone for Rosetta before controllers put the spacecraft into hibernation early in 2011, only to wake up in early 2014 for approach to comet 67P/Churyumov-Gerasimenko.
NASA has contributed an ultraviolet instrument (Alice); a plasma instrument (the Ion and Electron Sensor); a microwave instrument (Microwave Instrument for the Rosetta Orbiter); and portions of the electronics package for the double focusing mass spectrometer of the Rosetta orbiter sensor for ion and neutral analysis (ROSINA), among other contributions to this international mission.
