Occultation of asteroid 136199 Eris – November 6th 2010 2h15 TU – This occultation was predicted by Marcelo Assafin from Brazil about a year ago. Many astronomers worked in order to improve the astrometry, but it was a difficult task. Eris is about 32 milliarc second of diameter as seen from the Earth. One can see on Bruno Sicardy’s page that the predictions varied from Alaska to middle Chile according to whom made an astrometric reduction in order to know the position of the occulted star and that of Eris itself. –SpaceObs

Wonderful vistas from Cupola – Cupola has proved itself to be an excellent viewing platform since it was attached to the International Space Station in February. The latest photos taken from this heavenly observatory are stunning. –ESA

Astronomers Discover Merging Star Systems That Might Explode – Researchers who found the first hypervelocity stars escaping the Milky Way announced that their search also turned up a dozen double-star systems. Half of those are merging and might explode as supernovae in the astronomically near future. –Science Daily

Successful premiere – German robotic arm completes its five-year ISS mission – Germany’s first experiment in space robotics has now come to an end. On the evening of 15 November 2010, two Russian cosmonauts performed a space walk during which they removed the Rokviss robotic arm developed by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) from the experimental platform on the Russian service module Svezda and took it inside the ISS. By 2 November 2010, the Rokviss team from the DLR Robotics and Mechatronics Center in Oberpfaffenhofen had moved the robot arm into the required position for this operation. Only in this position could Rokviss be easily transported through the air lock and into the interior of the ISS. –DLR Portal

Dissolving Star Systems Create Mess in Orion – For young stars, stellar outflows are the rule. T Tauri stars and other young stars eject matter in generally collimated jets. However, a region in Orion‘s giant molecular cloud known as the Becklin-Neugebauer/Kleinmann-Low (BN/KL) region, appears to have a clumpy, scattered set of outflows with “finger-like” projections in numerous directions. A new study, led by Luis Zapata at the National Autonomous University of Mexico, explores this odd region. -Jon Voysey / Universe Today

On October 9, 2010, Chang'E 2 performs its second luanr orbit trim maneuver, an event witnessed by an engineering camera. Before the maneuver starts, the spacecraft executes a sequence of controlled turns, causing the Moon to swing through the field of view. The firing of the engine begins just after the terminator passes out of view (from the camera's point of view). As the spacecraft drops completely into the lunar shadow, the camera's automatic exposure setting adjusts brighter, making part of the spacecraft visible in light emitted from the glowing thruster.
