The first firm details of the 15 February asteroid impact in Russia, the largest in more than a century, are becoming clear. ESA is carefully assessing the information as crucial input for developing the Agency's asteroid-hunting effort.

Russian Asteroid Strike As Seen From Space

A space rock a few metres across exploded in Earth's atmosphere above the city of Chelyabinsk, Russia on 15 February at about 03:15 GMT. The numerous injuries and significant damage remind us that what happens in space can affect us all.

NASA Television will provide commentary starting at 11 a.m. PST (2 p.m. EST) on Friday, Feb. 15, during the close, but safe, flyby of a small near-Earth asteroid named 2012 DA14. NASA places a high priority on tracking asteroids and protecting our home planet from them. This flyby will provide a unique opportunity for researchers to study a near-Earth object up close.

The demise of the dinosaurs is the world's ultimate whodunit. Was it a comet or asteroid impact? Volcanic eruptions? Climate change?

Close Earth Flyby By Asteroid 2012 DA14

A little-known asteroid will skim past Earth on 15 February, passing just 28 000 km from our planet. The 50 m-diameter chunk of space rock was discovered in last year by ESA-sponsored amateur astronomers in Spain.

Rebutting a speculative hypothesis that comet explosions changed Earth's climate sufficiently to end the Clovis culture in North America about 13,000 years ago, Sandia lead author Mark Boslough and researchers from 14 academic institutions assert that other explanations must be found for the apparent disappearance.

An Asteroid Belt Around Vega?

Astronomers have discovered what appears to be a large asteroid belt around the star Vega, the second brightest star in northern night skies. The scientists used data from NASA's Spitzer Space Telescope and the European Space Agency's (ESA) Herschel Space Observatory, in which NASA plays an important role.

NASA scientists have announced that new observations of 2011 AG5 show that this asteroid, once thought to have a worrisome potential to threaten Earth, no longer poses a significant risk of impact.

China's Chang'e-2 spacecraft did a flyby of asteroid Toutatis yesterday. Higher resolution images will be released shortly. Image source: CNSA

Radar Images of Asteroid Toutatis

Sequences of Goldstone delay-Doppler radar images of Toutatis from the 2012 observing campaign. In each image, range increases down and Doppler frequency increases toward the right, so rotation is counterclockwise.

Radar Images of Asteroid 2007 PA8

A collage shows nine radar images of near-Earth asteroid 2007 PA8 that were obtained between Oct. 31 and Nov. 13, 2012, with data collected by NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif.

This composite image of asteroid 2007 PA8 was obtained using data taken by NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif.

Dawn Sees 'Young' Surface on Vesta

Like a Hollywood starlet constantly retouching her makeup, the giant asteroid Vesta is constantly stirring its outermost layer to present a young face. Data from NASA's Dawn mission show that a form of weathering that occurs on the moon and other airless bodies we've visited in the inner solar system does not alter Vesta's outermost layer in the same way.

Scientists using data from NASA's Wide-field Infrared Survey Explorer, or WISE, have uncovered new clues in the ongoing mystery of the Jovian Trojans -- asteroids that orbit the Sun on the same path as Jupiter. Like racehorses, the asteroids travel in packs, with one group leading the way in front of the gas giant, and a second group trailing behind.

Pristine material that matches comets in our own Solar System have been found in a dust belt around the young star Beta Pictoris by ESA's Herschel space observatory.

The world's first privately funded deep space mission - SENTINEL - received major support this week from prominent members of the business and financial community who joined the B612 Foundation's Founding Circle.

Vesta in Dawn's Rear View Mirror

NASA's Dawn mission is releasing two parting views of the giant asteroid Vesta, using images that were among the last taken by the spacecraft as it departed its companion for the last year.

Name an Asteroid

"Students worldwide have an opportunity to name an asteroid from which an upcoming NASA mission will return the first samples to Earth. Scheduled to launch in 2016, the mission is called the Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx). Samples returned from the primitive surface of the near-Earth asteroid currently called (101955) 1999 RQ36 could hold clues to the origin of the solar system and organic molecules that may have seeded life on Earth. NASA also is planning a crewed mission to an asteroid by 2025. A closer scientific study of asteroids will provide context and help inform this mission. The competition is open to students under age 18 from anywhere in the world. Each contestant can submit one name, up to 16 characters long. Entries must include a short explanation and rationale for the name. Submissions must be made by an adult on behalf of the student. The contest deadline is Sunday, Dec. 2, 2012." More

"Discovered by Lincoln Near Earth Asteroid Research (LINEAR), NEA (near-Earth asteroid) 2002 AM31, an asteroid the size of a city block, will make its close approach to Earth Sunday evening (July 22) -- just 39 days after newly discovered asteroid 2012 LZ1 paid an unexpected visit to Earth. Slooh Space Camera will cover its near-approach live on http://www.slooh.com, free to the public, starting at 4:30 p.m. PDT / 7:30 p.m. EDT / 23:30 UTC -- accompanied by real-time discussions by Slooh's Patrick Paolucci and Astronomy magazine columnist Bob Berman."

In a press conference at the California Academy of Sciences Thursday morning, the B612 Foundation unveiled its plans to build, launch, and operate the first privately funded deep space mission - SENTINEL - a space telescope to be placed in orbit around the Sun, ranging up to 170 million miles from Earth, for a mission of discovery and mapping.
