ARLINGTON, Va. -
NASA and ATK (NYSE: ATK) have successfully completed two key avionics tests for the solid rocket boosters for the space agency's new heavy lift rocket, the Space Launch System (SLS), being constructed to embark on bold missions to explore deep space.
The avionics tests, called hot fires, operate the booster's thrust vector control (TVC) system as if the booster were actually launching the SLS on a mission. The tests were conducted at ATK's Promontory, Utah, facility and repres...
"The key to this was that we were able to get continuous observations that are only available from space and from this instrument," he said.
They looked at the motion of supergranules hourly over several 27-day solar rotations with the expectation that they would be carried from the centers to the boundaries of giant cells by the slow but long-lived flow.
When the data was examined, the movement of giant cells became obvious on the computer screen. "It just jumps right ...
A new analysis of data from NASA's Galileo mission has revealed clay-type minerals at the surface of Jupiter's icy moon Europa that appear to have been delivered by a spectacular collision with an asteroid or comet. This is the first time such minerals have been detected on Europa's surface. The types of space rocks that deliver such minerals typically also often carry organic materials.
"Organic materials, which are important building blocks for life, are often found in ...
NASA reported a problem Wednesday at the International Space Station but said the crew was not in any danger.
One of two large coolant loops at the ISS -- on which electrical systems ride -- shut down earlier in the day, Josh Byerly, a spokesman for the US space agency, told AFP.
"At no time was the crew ever in danger," Byerly said. "The crew is fine." He said the issue is likely linked to a valve problem.
A lot of the systems in European and Japanese laborato...
The bad news: Earth's oceans will evaporate away.
The good news: It won't happen for another billion years or so.
Those are the conclusions of a new study into the so-called Goldilocks zone -- the distance from a star at which water on a rocky planet can exist as a liquid rather than as permanent ice or vapour.
As in the fairy tale, a planet's temperature has to be not too hot and not too cold, but just right for sustaining the stuff for life as we know it.
