The planet Mercury earned a new crater when NASA’s MESSENGER probe smashed into its scorched surface earlier this afternoon. The intentional crash landing ended an 11-year mission that brought us the most intimate peeks at our solar system’s smallest planet. … Continue reading
The world’s first space telescope celebrates a quarter century this week. NASA’s Hubble Space Telescope launched into orbit aboard the space shuttle Discovery 25 years ago Friday, on April 24, 1990. Continue reading
After spending nearly eight years floating through deep space, NASA’s Dawn spacecraft finally reached its destination Friday, a dwarf planet in the asteroid belt called Ceres. Continue reading
Science correspondent Miles O’Brien joins Judy Woodruff to discuss two space stories that center around the search for life and how it began. NASA’s Dawn spacecraft arrived in orbit around the dwarf planet Ceres, which scientists believe shows signs of life-sustaining water. Meanwhile, new research found that Mars once had enough water to cover 20 percent of the planet. Continue reading
NASA’s Curiosity rover will take a break from gathering samples of the dusty Martian landscape, while engineers determine whether a short circuit damaged the robot’s arm, the space agency’s Jet Propulsion Laboratory said Tuesday. Continue reading
Years into its nearly decade-long mission to survey the asteroid belt, NASA’s Dawn spacecraft traveled through deep space to better understand the dwarf planet Ceres. Now within 52,000 miles of the celestial body, Dawn’s latest images still leave scientists baffled about Ceres’ bright white spots.
Michael McDonnell has climbed Mount Kilimanjaro. He has a physics degree. He’s worked in hazardous environments. His hope is that these qualifications will convince a selection committee that he’s the perfect candidate for the first human voyage to Mars.
So far, it has. He was among the final 100 candidates — 50 men and 50 women — announced for the Mars One mission today, down from an initial candidate pool of 200,000. Continue reading
Three billion miles from Earth, the New Horizons space probe sent back its first images of Pluto and its largest moon Charon. Moving at 31,000 miles per hour, New Horizons is set to snap more photos in the coming months, revealing the mystery planet in clear detail for the first time. Continue reading
Earth’s close encounter with Asteroid 2004 BL86 on Monday revealed that the massive space object had a traveling companion: its own moon. Continue reading
