HAYABUSA 2 IS ABOUT TO LAUNCH http://www.sciencemag.org/content/346/6213/1040.full On 30 November, Hayabusa 2 will lift off from Japan’s Tanegashima Space Center on a 6-year round trip to asteroid 1999 JU3. If all goes as planned, it should bring home samples not just from the asteroid’s surface but also from beneath it, by blasting a crater and collecting ejecta. =================================== ASTEROID IMPACT THREAT: EXPERTS REPORT ON EARLY-WARNING STRATEGIES Leonard David, in Space News, November 20 (heavily edited)
Launch of the Hayabusa-2 asteroid explorer

The Hayabusa 2 is scheduled for launch on next Sunday, November the 30th 2014. The Hayabusa-2 is the follow-up of the highly succesful Japanees Hayabusa-1
NASA publishes map on small asteroid impacts
Last week NASA published this map of the world that shows all the impacts of small asteroids onto our planet that they have recorded over the past 20 years. They have recored so called bolide events, which you might refer to as “fireball in the sky”. These bolide events happen more often than you might have though, about every other week a object of a meter or more hits the Earth and disintegrates in out

NEW ESTIMATE OF NUMBERS OF SMALL NEAS CONFORMS TO RECENT ESTIMATE FROM BOLIDE EVENTS For more than 15 years NEO News has been quoting periodic updates from Alan Harris on the size distribution of NEAs. His synthesis of data from a variety of sources has been used as input for estimates of the risk of impacts and as a tool for evaluating the progress of NEA surveys and predicting the anticipated results from new surveys.
