Early in the morning on January 13, 2014, a 6.4 magnitude earthquake struck beneath the Atlantic Ocean north of Puerto Rico, damaging Arecibo Observatory, the world’s largest single-dish radio telescope. The telescope is now operational after repairs and scientists have resumed observations. However, the future of Arecibo Observatory remains unclear due to funding uncertainties in the federal budget.

Planetary Radio: NEOWISE PI Amy Mainzer
NEOWISE has reawakened to discover more asteroids and comets. The mission leader thanks the amateur astronomers who follow up.

A cute video from the OSIRIS-REx mission in the style of "AsapSCIENCE" uses a whiteboard and stop-motion animation to separate asteroid fact from fiction.
There is a paper in press at Icarus by Xiaoduan Zou and five coauthors that provides the first peer-reviewed publication I've seen on the results of the imaging experiment performed during the Chang'e 2 flyby of near-Earth asteroid (4179) Toutatis.
Shoemaker NEO Grant winner Bob Stephens specializes in lightcurves of near Earth asteroids to determine their physical properties. Here is an update on recent progress using his 2013 Planetary Society grant. This is the first in a series of updates on Shoemaker NEO Grant winners.
For those wishing to bore into more details of our Laser Bees project itself, graduate student Alison Gibbings from the University of Strathclyde has sent their technical paper that resulted from the 2013 Planetary Defense Conference.
Found a Killer Asteroid? Who Ya Gonna Call?

Astronomer Timothy Spahr directs the Minor Planet Center, the global clearinghouse for asteroids, comets and other relatively small objects in the solar system, including moons. He also coordinates the Society's Shoemaker NEO grant program.
Planetary Defense Conference 2013 Part 3
Part 3 of Bruce Betts' wrap up from the Planetary Defense Conference 2013 focuses on the Laser Bees (asteroid deflection method) project and Laser Bees researcher Alison Gibbings.
A large asteroid is passing reasonably close to Earth in a few hours, and astronomers at the great radio telescopes at Goldstone and Arecibo are zapping it. The latest discovery: QE2, like many asteroids, is a binary.

This week I'll be talking with NEOWISE principal investigator Amy Mainzer about moving objects that the WISE mission has spotted both inside and outside our solar system.
A frequently-asked question last week was: if asteroid 2012 DA14 is coming so close to Earth, why hasn't anyone taken any pictures of it? Now that 2012 DA14 has whizzed past us, we do finally have some radar pictures of it, but they still may not satisfy everyone.
