April 17, 2013 Antares is designed to ferry cargo to the International Space Station. The two-stage rocket, a milestone for commercial space flight, is scheduled to lift off from NASA's Wallops Flight Facility in Virginia on Wednesday.
April 14, 2013 Communications between the Earth and Mars are going on a month-long hiatus, thanks to interference from the sun. That means NASA's spacecraft on Mars will be on their own until NASA's radio signals can reach them again.
April 12, 2013 The Russian president says the part of the money will go to complete a new launch facility under construction in the country's far east.
April 12, 2013 There's $78 million of the agency's nearly $18 billion budget set aside for a program to capture a 500-ton asteroid in space and drag it back to orbit around the moon. And by 2021, astronauts could be visiting that asteroid to study it up close and gather samples.
April 11, 2013 The rock found in Morocco was even weirder than it looked. The olive green chunk, speckled with white and brown, has chemical and physical properties similar to the planet Mercury. But some experts doubt that the 4.56-billion-year-old meteorite is from the planet closest to our sun.
April 3, 2013 The finding could be a milestone in the decades-long search for the universe's missing material. But some scientists urge caution, saying it's possible the particles seen by the sensor on the International Space Station could have come from somewhere else.
March 29, 2013 The latest Soyuz reached the International Space Station in just six hours instead of two days. It was the first manned mission to accomplish the feat.
March 27, 2013 The new type of supernova is fainter, less energetic and rarer than the ones already known.
March 26, 2013 The second unmanned commercial space mission to the International Space Station returns with more than 1 ton of cargo.
March 21, 2013 European scientists say new data from the Planck probe show that the universe is 13.82 billion years old instead of 13.77 billion, as previously thought.
March 20, 2013 Scientists told a Senate panel that getting caught off-guard by a space rock hurtling toward Earth would lead to devastating consequences.
March 20, 2013 Some of the most powerful U.S. rocket engines ever built have been raised from the depths off Florida. The Apollo-era motors are to be restored and put on display. Meanwhile, NASA has pulled unused copies of the same engine out of storage and fired them up as part of its program to build new heavy lift rockets.
March 15, 2013 The comet's now putting on a show in the Northern Hemisphere's night sky. Using its orbiting observatories, NASA captured a stereo view from space that offers a unique perspective.
