Photos of the Day: NASA's flying saucer

April 21, 2014 1:33 pm | by ECN Staff | News | Comments

NASA recently unveiled the Low Density Supersonic Decelerator, a disc-shaped spacecraft which could potentially deliver supplies for future manned Mars missions. In theory, NASA’s flying saucer would, upon descent, deploy a 100-foot-wide parachute to decelerate from a Mach 3.5 descent down to about twice the speed of sound....

Astronaut pee could help get us to Mars

April 21, 2014 8:16 am | by Jason Lomberg, Technical Editor | Blogs | Comments

Stop me if you’ve heard this before: Urine, made up of more than 95% water, is one of the cleanest fluids in the human body. And on a protracted space mission lasting more than a year (one-way) — to Mars, for example — that fact becomes critically important....

Bright points in sun's atmosphere mark patterns deep in its interior

April 18, 2014 1:40 pm | by EurekAlert! | News | Comments

Like a balloon bobbing along in the air while tied to a child's hand, a tracer has been found in the sun's atmosphere to help track the flow of material coursing underneath the sun's surface. New research that uses data from NASA's Solar Dynamics Observatory, or SDO, to track bright points in the solar atmosphere...

Engineering Update 54: NASA to send flying saucers to Mars

April 17, 2014 10:25 am | by Jon Dipierro, Multimedia Production Specialist | Videos | Comments

Future voyages to Mars would need to address the physiological strain on the astronauts, the length of the trip, itself, and ferrying the necessary payload to sustain human life for a protracted mission. The first two problems could be insurmountable, but to deal with the latter, NASA is currently testing its own prototype for a hypersonic flying saucer....

Odd tilts could make more worlds habitable

April 16, 2014 1:11 pm | by EurekAlert! | News | Comments

Pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable, according to new modeling by NASA and university scientists affiliated with the NASA Astrobiology Institute. The climate effects generated on these wobbling worlds could prevent them from turning into glacier-covered ice lockers....

Photos of the Day: The amazing, foldable V-22 Osprey

April 15, 2014 8:18 am | by ECN Staff | News | Comments

It’s also capable of both vertical takeoff and landing (VTOL) and short takeoff and landing (STOL). But one of the Osprey’s coolest features is its ability to fold its rotors back for compact storage capabilities....

Watch a V-22 Osprey fold itself for storage

April 14, 2014 3:07 pm | by Kasey Panetta, Managing Editor | Blogs | Comments

 It’s pretty crazy to think that a huge aircraft with an 85’ foot wingspan is possible of folding itself up to reduce the amount of space it occupies on a massive ship. Yet, the V-22 Osprey does just that. This video is a little dated—it was taken in 2010 at Nellis Airforce Base in Las Vegas....
