Bits & pieces

MUSES-C Hayabusa:  Tumbling Stone today posted its issue #22 (temporary URL), dated October 30th. It includes two articles about the JAXA MUSES-C Hayabusa mission. Mention is made of the spacecraft's LIDAR instrument (LIght Detection And Ranging), which, once in orbit about the destination asteroid, will be used to determine the asteroid's shape and help map its surface, and then will be used as an altimeter during the initial descent to a landing as part of the spacecraft's autonomous navigation system.

Hermes:  The UCLA Daily Bruin has an article today, "UCLA researcher finds asteroid Hermes to be binary." (The mention of "Goldenstone" should be "Goldstone".) See A/CC's "1937 UB Hermes Day-by-Day" for more info and links.

LBTO news:  The University of Arizona has a news release from yesterday, "World's Largest Telescope Mirror Moves up Mountain." This is the first mirror of the Large Binocular Telescope Observatory (LBTO) finishing a journey that began in Italy in 1997 and ended in a one-mile-per-hour drive up Mt. Graham Observatory's twisty access road. When completed, according to the LBTO site, the "two 8.4-meter mirrors on a common mount . . . will be equivalent in light-gathering power to a single 11.8 meter instrument [with] a resolving power (ultimate image sharpness) corresponding to a 22.8-meter telescope." A/CC isn't aware of any minor object science planned for this facility, but its primary mission is planetary science: to directly observe planets in other solar systems.

Risk monitoring
4 Nov.

The Tuesday Daily Orbit Update MPEC (DOU) carries the good news that Arecibo in Puerto Rico successfully observed 2003 TH2 by radar last Thursday. And observations of 2003 UO12 are reported from Saturday from Siding Spring in Australia, and from last night from Linz Observatory in Austria.

Today NEODyS removed both objects, while JPL significantly lowered its risk rating on 2003 UO12. At 10:30pm in Pasadena, JPL had not yet updated its 2003 TH2 risk assessment using this morning's new radar data.
