Scientists have determined that a wind-driven "tumbleweed" Mars rover would be more than capable of effectively navigating rocky Martian terrain.
We've arrived late for the cosmic show - too late for the best seat, says Harvard theorist Avi Loeb. He says the ideal time to study the cosmos was more than 13 billion years ago, just half a billion years after the Big Bang.
The Dragon spacecraft - built by Space X - is en route to the International Space Station (ISS) after a successful launch atop a Falcon 9 rocket from the Cape Canaveral Air Force Station earlier this morning.
SpaceX was forced to abort the launch of its Falcon 9 mission to the International Space Station on Saturday, just half a second before liftoff.
MIT and NASA scientists believe they've found a planet, 1,500 light years away, that appears to be disintegrating from the heat of its parent star.
ESA's Herschel Space Observatory has discovered a giant, galaxy-filled filament connecting two clusters of galaxies.
The Dragon spacecraft is undergoing last minute preparations as it readies for a demonstration flight to the International Space Station (ISS).
On Sunday, millions of people around the world will be treated to an amazing sight: an annular solar eclipse in which the moon will cover as much as 94 percent of the sun, leaving a glowing ring of fire.
Observations from NASA's Wide-field Infrared Survey Explorer (WISE) indicate there are about twice as many potentially hazardous asteroids (PHAs) in lower-inclination orbits than previously believed.
An international research team has managed to observe the active accretion phase of a supermassive black hole in the center of a galaxy tens of millions of light years away.
Solar power collected in space could ultimately be tapped to provide the renewable energy of the future.
Late last night, three astronauts blasted off for the International Space Station on a Soyuz TMA-04M, after several weeks of delay.
NASA recently tested a Mars rover in California's Mojave Desert to prepare for the August landing of its Curiosity rover on the red planet.
NASA, along with a number of international partners, is currently working on the HIFiRE (Hypersonic International Flight Research Experimentation Program) program to advance hypersonic flight.
The asteroid Vesta is more like a planet or a moon, new data from NASA's Dawn spacecraft shows.
Our sun is moving through the Milky Way more slowly than thought, new data from NASA's Interstellar Boundary Explorer (IBEX) satellite shows.
ATK has developed a complete commercial crew transportation system, including a spacecraft, abort system, launch vehicle, as well as ground and mission operations.
Scientists using the Herschel Space Observatory have discovered that galaxies with the most powerful, active black holes at their heart produce fewer stars.
NASA's Mars Reconnaissance Orbiter (MRO) has revealed that sand dunes on Mars can put on a surprising turn of speed.
NASA scientists have, for the first time, seen the light from a planet outside our solar system that's a similar size to the Earth.
