It's now been two years since Dawn wrapped up its work at the second-largest asteroid. What else did we get from the Vesta encounter besides great photos? Recently, I asked Dawn's deputy project scientist, Carol Raymond, for help in summarizing a few of the big things Dawn taught us.
You have just until September 30, 2014 at 23:59 Pacific time, to submit your name, and to tell your friends and family to submit their names, to fly to asteroid Bennu and back on board NASA’s OSIRIS-REx mission.
You have four weeks left (until September 30, 2014) to submit names to send to an asteroid, and now you can also separately submit space exploration predictions or images to send in a time capsule to and from that same asteroid. Both sets of information will fly etched on microchips on board the NASA OSIRIS-REx spacecraft.
The asteroid community recently gathered in Helsinki, Finland for the 12th Asteroids, Comets, and Meteors Conference. As this meeting showed, one of the hottest topics in asteroid science is the study of asteroid families.
What a great piece of news to receive upon returning home from vacation! There is now a small piece of the solar system named for me: asteroid 274860 has been formally named "Emilylakdawalla" by the International Astronomical Union. Here is everything I've been able to learn about my namesake asteroid.
The Planetary Society strongly supports NASA's asteroid initiative, including the goal of redirecting an asteroid to the vicinity of the Moon. But an independent cost estimate is needed, and needed soon.
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.
At the Lunar and Planetary Science Conference, Jennifer Scully discussed possible water-carved gullies in an unusual location: within craters on Vesta. Water-carved gullies on Mars I can accept; but on an airless lumpy body? I was intrigued.
