Newly-discovered asteroid 2011 MD will pass only 12,000 kilometers (7,500 miles) above Earth’s surface on Monday, June 27th at about 9:30AM EDT. NASA analysts say there is no chance the space rock will strike Earth. Nevertheless, the encounter is so close that Earth’s gravity will sharply perturb the asteroid’s trajectory.
The asteroid was discovered by the LINEAR near-Earth object discovery … Read the rest of this article
ESA and NASA have announced the scientific investigations selected for their 2016 ExoMars lander demonstrator. They will probe the atmosphere during the descent, and return the first ever data on electrical fields at the surface of Mars.

Yesterday morning (June 7th) around 06:41 UT, magnetic fields above sunspot complex 1226-1227 became unstable and erupted. The blast produced an M2-class solar flare, an S1-class radiation storm, and a massive CME. A recording of the blast from NASA’s solar Dynamics Observatory ranks as one of the most beautiful and dramatic movies of the SDO era. This video of the … Read the rest of this article
NASA has ended operational planning activities for the Mars rover Spirit and transitioned the Mars Exploration Rover Project to a single-rover operation focused on Spirit’s still-active twin, Opportunity.
This marks the completion of one of the most successful missions of interplanetary exploration ever launched.
Spirit last communicated on March 22, 2010, as Martian winter approached and the rover’s solar-energy supply … Read the rest of this article
An assorted mix of colorful galaxies is being released today by NASA’s Wide-field Infrared Survey Explorer mission, or WISE. The nine galaxies are a taste of what’s to come. The mission plans to release similar images for the 1,000 largest galaxies that appear in our sky, and possibly more.

A five-year survey of 200,000 galaxies, stretching back seven billion years in cosmic time, has led to one of the best independent confirmations that dark energy is driving our universe apart at accelerating speeds.
The survey used data from NASA’s space-based Galaxy Evolution Explorer and the Anglo-Australian Telescope on Siding Spring Mountain in Australia.

NASA’s Dawn spacecraft has obtained its first image of the giant asteroid Vesta, which will help fine-tune navigation during its approach. Dawn is expected to achieve orbit around Vesta on July 16, when the asteroid is about 188 million kilometers (117 million miles) from Earth.

Newly-discovered asteroid 2011 GP59 is flying past Earth today, April 15th, not far beyond the orbit of the Moon (1.4 LD). There’s no danger of a collision, but the 50-meter space rock is remarkable: It is elongated and spinning once every 7.5 minutes. This causes the asteroid to flash like a strobe light. A video taken by Joe Pollock of … Read the rest of this article

After three and a half years of thrusting silently through the void, NASA’s Dawn spacecraft is on the threshold of a new world. It’s deep in the asteroid belt, less than 4 months from giant asteroid Vesta.
“We’re closing in,” says Marc Rayman, Dawn’s chief engineer and mission manager. “And I’m getting more excited every day!”
Dawn will enter orbit … Read the rest of this article
