[meteorite-list] Farewell Rosetta: ESA Mission to End on Comet Surface
http://www.jpl.nasa.gov/news/news.php?feature=6633 Farewell Rosetta: ESA Mission to End on Comet Surface Jet Propulsion Laboratory September 29, 2016 The European Space Agency's (ESA) Rosetta mission will come to a dramatic end on Friday, Sept. 30, with a controlled touchdown of the spacecraft on a region of comet 67P/Churyumov-Gerasimenko known for active pits that spew comet dust into space. Confirmation of the end of mission is expected at about 4:20 a.m. PDT (7:20 a.m. EDT). ESA is ending the mission due to the spacecraft's ever-increasing distance from the sun, which has resulted in significantly reduced solar power with which to operate the vehicle and its instruments. Rosetta is an international mission led by ESA with instruments provided by its member states, and additional support and instruments provided by NASA. "The European Space Agency's Rosetta Mission is a magnificent demonstration of what excellent mission design, execution, and international collaboration can achieve," said Geoff Yoder, acting associate administrator for NASA's Science Mission Directorate in Washington. "Being neighbors with a comet for more than two years has given the world invaluable insight into these beautiful nomads of deep space. We congratulate ESA on its many accomplishments during this daring mission." The final hours of descent will enable Rosetta to make many once-in-a-lifetime measurements, including analyzing gas and dust closer to the surface than ever possible before, and taking very high-resolution images of the comet nucleus. The images will include views of the open pits of the Ma'at region, where the spacecraft is expected to make its controlled impact. Ma'at is home to several active pits more than 330 feet (100 meters) in diameter and 160 to 200 feet (50 to 60 meters) deep. The walls of the pits exhibit intriguing lumpy structures about 3 feet wide (1 meter wide) called "goose bumps." Scientists believe those structures could be the signatures of early cometesimals that assembled to create the comet in the early phases of solar system formation. Rosetta will attempt to get its closest look yet at these fascinating structures on Sept. 30, when the spacecraft will target a point adjacent to a 430-feet-wide (130-meter), well-defined pit that the mission team has informally named Deir el-Medina. "Rosetta will keep giving us data to the very end," said Bonnie Buratti, project scientist for the U.S. Rosetta project from NASA's Jet Propulsion Laboratory in Pasadena, California. "NASA's three instruments aboard Rosetta will be among those collecting data all the way down." Those three NASA science instruments are: the Microwave Instrument for Rosetta Orbiter (MIRO); an ultraviolet spectrometer called Alice; and the Ion and Electron Sensor (IES). They are part of a suite of 11 science instruments on the orbiter. MIRO was designed to provide data on how gas and dust leave the surface of the nucleus to form the coma and tail that give comets their intrinsic beauty. Studying the surface temperature and evolution of the coma and tail provides information on how the comet evolves as it approaches and leaves the vicinity of the sun. MIRO has the ability to study water, carbon monoxide, ammonia and methanol. Alice, an ultraviolet spectrometer, analyzes gases in the comet's coma and tail; measures how fast the comet produces water, carbon monoxide and carbon dioxide (clues to the surface composition of the nucleus); and measures argon levels. These measurements help determine the temperature of the solar system when the nucleus formed more than 4.6 billion years ago. The Ion and Electron Sensor is part of a suite of five instruments that analyzes the plasma environment of the comet, particularly the coma. The instrument measures the charged particles in the sun's outer atmosphere, or solar wind, as they interact with the gas flowing out from the comet. NASA provided part of the electronics package for the Double Focusing Mass Spectrometer, which is part of the Swiss-built Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument. U.S. scientists also partnered on several non-U.S. instruments and were involved in seven of the mission's 26 instrument collaborations. NASA's Deep Space Network is supporting ESA's Ground Station Network for spacecraft tracking and navigation. NASA also provided autonomous science operations planning software, which helped in planning science operations and navigation support. The Rosetta mission was launched in 2004 and arrived at comet 67P/Churyumov-Gerasimenko on Aug. 6, 2014. It's the first mission in history to rendezvous with a comet and escort it as it orbits the sun. On Nov. 4, 2014, a smaller lander named Philae -- which had been deployed from the Rosetta mothership -- touched down on the comet and bounced several times before alighting on the surface. Philae obtained the first images

http://www.jpl.nasa.gov/news/news.php?feature=6630 NASA TV Coverage of European Mission Comet Touchdown Jet Propulsion Laboratory September 28, 2016 NASA Television and the agency's website will air the conclusion of ESA's (European Space Agency's) Rosetta mission from 3:15 to 5 a.m PDT (6:15 to 8 a.m. EDT) Friday, Sept. 30, with NASA commentary, interviews and analysis of the successful mission. The Rosetta mission will end with the controlled descent of the spacecraft onto the surface of comet 67P/Churyumov-Gerasimenko at around 4:20 a.m. PDT (7:20 a.m. EDT). Rosetta was launched in 2004 carrying 11 science instruments, with several contributions from NASA including: the Microwave Instrument for Rosetta Orbiter (MIRO); the Alice spectrograph; the Ion and Electron Sensor (IES); and the Double Focusing Mass Spectrometer (DFMS) electronics package for the Rosetta Orbiter Spectrometer for Ion Neutral Analysis (ROSINA). NASA's Deep Space Network supports ESA's Ground Station Network for spacecraft tracking and navigation. The spacecraft arrived at its destination comet on Aug. 6, 2014, becoming the first mission in history to rendezvous with a comet and escort it as it orbits the sun. About two months later, the small Philae lander deployed from Rosetta touched down on the comet and bounced several times before alighting on the surface. Philae obtained the first images ever taken from the surface of a comet, and sent back valuable scientific data for several days. ESA is ending the mission because the spacecraft's ever-increasing distance from the sun has resulted in significantly reduced solar power to operate the spacecraft and its instruments. Comets are time capsules containing primitive material left over from the epoch when the sun and its planets formed. Rosetta is the first spacecraft to witness up close how a comet changes as it is subjected to the increasing intensity of the sun's radiation. Observations will help scientists learn more about the origin and evolution of our solar system and the role comets may have played in the formation of planets. In addition to NASA's contribution, Rosetta's Philae lander was provided by a consortium led by the German Aerospace Center, Max Planck Institute for Solar System Research, French National Space Agency, and Italian Space Agency. NASA's Jet Propulsion Laboratory in Pasadena, California, manages the U.S. contributions to the Rosetta mission for the agency's Science Mission Directorate in Washington. JPL also built the MIRO and hosts its principal investigator, Mark Hofstadter. The Southwest Research Institute developed Rosetta's IES and Alice instruments and hosts their principal investigators, James Burch for IES and Alan Stern for the Alice instrument.
