NASA is planning to maximize the scientific potential of the maiden launch of its next generation launch vehicle, the Space Launch System, by selecting 11 tiny satellites to ride shotgun. The little probes, known as CubeSats, will be transported in the SLS's upper stage adaptor, presenting a cost-effective delivery option for experiments designed to function beyond low-Earth orbit.  Read More

Asteroid Redirect Vehicle landing (Image: NASA)

NASA has released new details on how it plans to boldly go to an asteroid and come back with a bit of it. The Asteroid Redirect Mission (ARM) is part of the space agency's Asteroid Initiative announced in 2013, which envisions the capture and return of an asteroid to lunar orbit for study by astronauts as a rehearsal for a later mission to Mars.  Read More

Geophysicists have stumbled across what is believed to be the largest asteroid impact zone...

Geophysicists conducting drilling as part of geothermal research claim to have stumbled across the largest asteroid impact zone ever found on Earth. Covering a 400 km (249 mi) wide area in Central Australia, the two ancient craters are believed to be the result of a single meteorite that split in two moments before crashing into the Earth.  Read More

New software based on an algorithm developed in an open competition hosted by NASA improves the detection rate of potentially hazardous near-Earth asteroids. The software comes in the form of a free-to-download application, capable of being run from most laptops or desktops, transforming any amateur astronomer into a seasoned asteroid hunter.  Read More

NASA's Dawn spacecraft added another trophy today to the conquest of space as it went into orbit around Ceres. According to the space agency, the unmanned probe arrived at about 4:39 am PST and is currently circling the dwarf planet at an altitude of about 38,000 miles (61,000 km) – making it not only the first spacecraft to reach a dwarf planet, but also the first to orbit two extraterrestrial bodies.  Read More

As NASA’s Dawn spacecraft makes its final approach to Ceres, the ion-propelled spacecraft is sending the best images yet with more details about the surface of the dwarf planet. The images from Dawn have shown the presence of numerous craters and unusual bright spots that scientist hope will provide clues as to not only how Ceres formed and if it is still active, but the early history of the Solar System as well.  Read More

The CubeSats would hitch a ride with ESA’s Asteroid Impact Mission (Image:ESA/APL)

CubeSats offer a way to get into space on the cheap. They're compact, inexpensive, and they can piggyback on larger launch payloads to get into orbit. The trouble is, this piggybacking is often like trying to hitchhike cross country on a ride that only goes to the edge of town. The European Space Agency is widening the scope a little by opening a competition for CubeSats to ride into deep space on its Asteroid Impact Mission (AIM).  Read More

Asteroid 2004 BL86 and its moon (Image: NASA)

You may not have noticed, but the Earth had a close shave on Monday as an asteroid with its own moon made a cosmic near miss. As it passed within 3.1 times the distance from the Earth to the Moon, NASA's 230-foot-wide Deep Space Network captured radar images of asteroid 2004 BL86 and its tiny satellite.  Read More

The latest images have 30 percent better resolution than those captured by Hubble (Image: ...

The dwarf planet Ceres has come into sharper focus with NASA's Dawn spacecraft sending back the best images yet of the asteroid. Shot on January 25 from a distance of 147,000 mi (237,000 km) as the unmanned probe closes in for its March rendezvous, the resolution was 30 percent better than the best images obtained by the Hubble space telescope.  Read More

Artist's concept of Dawn approaching Vesta under ion drive (Image: NASA)

The last place you'd expect to find signs of water erosion is in the Asteroid Belt, but researchers from NASA's Jet Propulsion Laboratory say that data collected during the Dawn spacecraft's visit to Vesta indicates that it not only once had water, but that it formed gullies and other erosion features on its surface.  Read More
