Using AWS’s cloud to operate the mars.jpl.nasa.gov website, Shams noted, enables JPL to get images, videos and developments to the public quickly, without having to build and operate the infrastructure in-house.
According to Amazon, AWS enabled JPL to construct a scalable Web infrastructure in only two to three weeks instead of months.

“We need to take a whole series of steps to make that software active,” said Steve Scandore, a senior flight software engineer at NASA’s Jet Propulsion Laboratory. “You have to imagine that if something goes wrong with this, it could be the last time you hear from the rover.”

Curiosity, while working on Mars alone, needs to be told what it will do every day — move across the bottom of the crater, zap a rock with its laser, scoop up a soil sample. And once a team of NASA scientists make the daily decision as to what the rover will do, programmers have to begin furiously working on up to a 1,000 different commands that will be uploaded to the rover.
NASA’s Curiosity rover has landed on Mars! Its descent-stage retrorockets fired, guiding it to the surface. Nylon cords lowered the rover to the ground in the “sky crane” maneuver. When the spacecraft sensed touchdown,…

The sheer size of the Mars Science Laboratory rover (over one ton, or 900 kilograms) would preclude it from taking advantage of an airbag-assisted landing. Instead, the Mars Science Laboratory will use the sky crane touchdown system, which will be capable of delivering a much larger rover onto the surface. It will place the rover on its wheels, ready to begin its mission after thorough post-landing checkouts.
They have 2.4-meter (7.9 feet) mirrors, just like the Hubble. They also have an additional feature that the civilian space telescopes lack: A maneuverable secondary mirror that makes it possible to obtain more focused images. These telescopes will have 100 times the field of view of the Hubble, according to David Spergel, a Princeton astrophysicist and co-chair of the National Academies advisory panel on astronomy and astrophysics.
The surprise announcement Monday is a reminder that NASA isn’t the only space enterprise in the government — and isn’t even the best funded.

Charged Up: Electric Rockets Are Set to Transform Space Flight | Txchnologist.
NASA’s Dawn space probe, which is now exploring the asteroid Vesta, was among the first interplanetary craft to employ solar electric propulsion (SEP) for primary propulsion. But Dawn’s three electric engines are rated at only 2.3 kW each (3 horsepower), about the power of a small lawnmower engine, which means which means they had to produce their low thrust for years to build up the high velocity needed to travel to the distant asteroid in a reasonable time.
This tech is so cool.
NASA’s twin Grail probes are designed to map the moon’s gravity field like no other spacecraft before. The $496 million mission will use the ultra-precise moon gravity maps to help scientists better understand the moon’s composition and structure, as well as how the moon evolved during its formation. Learn how the Grail mission works in the SPACE.com infographic above.
