Mars Spacecraft Positioned for Oort Cloud Comet ‘Siding Spring’ Flyby

Mars Nov 2014

Mars with its 2 functioning rovers (Opportunity, Curiosity) and 5 orbiters (Mars Odyssey, Mars Express, Mars Reconnaissance Orbiter, Mars Orbiter Mission, MAVEN) will experience comet ‘Siding Spring C/2013 A1′ flying by with closest approach October 19 at 18:27 UT. It is expected to pass at ~55 km/sec within 139,500 km of the surface (about 1/3 of the distance between the Moon and Earth). All 7 spacecraft will observe and analyze the comet, as will Hubble, Kepler, Swift, Spitzer, SOHO, Chandra, Hawai’i-based Infrared Telescope Facility, and others. Siding Spring originates from the Oort Cloud, estimated to span from beyond the orbit of Pluto to about 1/4 of the distance to Proxima Centauri, the closest Star. The exact size, shape and composition of the comet’s nucleus is unknown and no Oort Cloud comet has been observed up close before. All 5 orbiters have been positioned behind the planet for protection from potential dust particle impacts. There is also a chance Siding Spring may break apart due to Mars’ gravitational pull. For ~2.5 days as it approaches and flies by, the spacecraft will image the comet and collect data to characterize materials and distributions, meteor trails, interactions with the atmosphere, and effects on air temperature and clouds.

China Chang’e Moon Program Advancing with Major Step Toward 2017 Sample Return

Calendar Feature - CE5-T1

Chang’e-5 Sample Return Test Orbiter (CE5-T1), the fourth flight to the Moon of the ambitious and successful China Lunar Exploration Program, will launch on a Long March 3C/E rocket from the Xichang Satellite Launch Center in southwest China on October 23. The spacecraft consists of the return vehicle, strikingly similar in appearance to the Shenzhou crew capsule, and a Service Module based on the CE2 orbiter design. This stack will be boosted into a parking orbit at about 200km altitude before re-ignition of the cryogenic upper stage for a 3-minute trans-lunar insertion burn. CE5-T1 will enter lunar orbit about 100 hours later. Various tests will be carried out before the craft fires engines to return toward Earth at 11.2km/s. The high speed Skip Re-entry demonstration is a complex procedure designed to reduce heat load and involves the capsule conducting an initial reentry to slow, then steering up to lift out of the atmosphere for a ballistic exospheric segment, followed by a gliding entry that slows the craft down enough to open parachutes and land accurately near Huofutan in Inner Mongolia. The full CE5 mission is set for 2017 and is intended to return up to 2kg of lunar material, including core samples collected via drilling mechanisms, to Earth. It is also widely seen as the final step before China attempts to meld its Human Space Flight program with the Lunar Exploration Program to initiate Human Moon missions.
