Sarah Ramsey / Rachel Kraft, NASA Headquarters As the next step in advancing NASA’s asteroid initiative, the agency will host an Opportunities Forum March 26 at NASA Headquarters in Washington. The forum, which is open to industry, academia and interested individuals, will provide status updates from ongoing asteroid redirect mission studies and summarize how responses to a 2013 Request for Information (RFI) are helping improve mission planning activities. The event will also...

Large Asteroid Passes Within A Few Million Miles Of Earth
2014-02-18 11:05:41

Lee Rannals for redOrbit.com - Your Universe Online The Earth faced a “close-call” on Monday night as near-Earth asteroid 2000 EM26 came within a couple million miles of the planet, nearly a year after the Chelyabinsk meteor exploded over Russia. The asteroid, which was estimated to be about the size of three football fields, whizzed by Earth last night at a distance of 2.1 million miles and traveling at about 27,000 mph. Slooh provided a broadcast of the event so online spectators...

Responding To Potential Asteroid Redirect Mission Targets
2014-02-15 06:26:56

NASA/Jet Propulsion Laboratory One year ago, on Feb. 15, 2013, the world was witness to the dangers presented by near-Earth Objects (NEOs) when a relatively small asteroid entered Earth's atmosphere, exploding over Chelyabinsk, Russia, and releasing more energy than a large atomic bomb. Tracking near-Earth asteroids has been a significant endeavor for NASA and the broader astronomical community, which has discovered 10,713 known near-Earth objects to date. NASA is now pursuing new...

NASA In June of last year, NASA Administrator Charlie Bolden spoke to the United Nations Committee on Peaceful Uses of Outer Space (COPUOS) and shared with the international community what NASA is doing to detect and track asteroids. He also engaged the United Nation’s support for NASA’s mission to find, capture and redirect an asteroid to lunar orbit, and then send humans to explore it by 2025. Following Bolden’s presentation, Mazlan Othman, director of the U.N. Office for Outer...

Astronomers Get A Good Look Inside Asteroid Itokawa
2014-02-05 12:24:19

[ Watch the Video: What's Inside An Asteroid? ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers, using the European Southern Observatory’s (ESO) New Technology Telescope (NTT), have discovered that asteroids have a highly varied internal structure. The astronomers used the instrument to look at different parts of the asteroid Itokawa, which was the target of the Japanese spacecraft Hayabusa in 2005. This spacecraft took samples of an asteroid for the first time and...

Hunting For Near-Earth Objects And Asteroids

Brett Smith for redOrbit.com - Your Universe Online For the first time, national space agencies from Africa, Europe, the Americas and Asia will establish an expert group aimed at getting the world’s space-faring nations on the ‘same page’ when it comes to reacting to asteroid threats, the European Space Agency (ESA) announced on Friday. Its task is to coordinate capabilities and expertise for missions to handle asteroids that might one day strike Earth. The Space Mission Advisory...

Brett Smith for redOrbit.com - Your Universe Online Once a hibernating craft drifting silently through space, NEOWISE was repurposed and reactivated last month with a new mission – find asteroids and other potentially hazardous near-Earth objects (NEO). On Thursday, NASA announced that the probe has identified 857 minor bodies in our solar system, including 22 NEOs and four comets, in its first 25 days of operation. Three of these NEOs are new discoveries measuring hundreds of feet in...

Asteroid Discovery Comes After NASA Reactivates NEOWISE
2014-01-08 10:07:31

Brett Smith for redOrbit.com - Your Universe Online Considering NASA’s recent budget cuts, re-purposing the space agency’s assets is more important than ever. One asset re-purposed by NASA, the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE), has made its first discovery since coming out of hibernation last year: a never-before-seen asteroid dubbed 2013 YP139. Formerly known as the Wide-field Infrared Survey Explorer (WISE), the orbiter was shut down in 2011 after...

WASHINGTON, Jan. 7, 2014 /PRNewswire-USNewswire/ -- NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft has spotted a never-before-seen asteroid -- its first such discovery since coming out of hibernation last year. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) NEOWISE originally was called the Wide-field Infrared Survey Explorer (WISE), which had made the most comprehensive survey to date of asteroids and comets.

NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...

Near-Earth Object -- Near-Earth Objects (NEO) are asteroids, comets and large meteoroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger. Due to their size and proximity, NEO's are also more easily accessible for spacecraft from Earth and are important for future scientific investigation and commercial development. In fact, some near-Earth asteroids can be reached with much less ΔV (change in velocity) than the Moon. In the United States, NASA...

Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less ΔV than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...

433 Eros -- The asteroid 433 Eros was named after the Greek god of love Eros. It is an S-type asteroid approximately 13 x 13 x 33 km in size, the second-largest near-Earth asteroid. It was visited by the NEAR Shoemaker probe, which first orbited it taking extensive photographs of its surface and then in 2001 at the end of its mission was landed on the asteroid's surface using only its maneuvering jets. Depending on where they stood on Eros, a person who weighed 200 pounds (90...
