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
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
In our news wrap Friday, police in France, Germany and Belgium arrested more than two dozen people with suspected links to Islamic militant groups. The head of Europol warned that Europe now has up to 5,000 Muslim radicals. Also, President Obama warned lawmakers that imposing new sanctions against Iran could end all hope for reaching a deal with that country on its nuclear program. Continue reading
NASA envisions a human presence on Mars in 20 years. But how will we get there? The Orion spacecraft, an unmanned capsule, will launch on its maiden voyage as an important test for future missions. Science correspondent Miles O’Brien reports on the engineering hurdles as well as the budgetary ones. Continue reading
It will take a big rocket to get to Mars, and a big space capsule to protect humans during the months-long journey. It also takes decades of testing and development to plan a mission that will take humans further into … Continue reading
Miles O’brien spoke with Rich Zurek, chief scientist of Mars Program Office at NASA’s Jet Propulsion laboratory, about particles in Comet Siding Spring’s tail that could collide with NASA’s Mars orbiters. The tiny tail particles, about a millimeter in size, can be traveling at up to 35 miles per second, so “if they encounter a spacecraft, they can go through just about anything,” Zurek said.
