NASA testing SLS for transonic behavior



Hampton VA (SPX) Jan 04, 2017
Tucked away in Hampton, Virginia, is a 56-year-old NASA wind tunnel capable of generating winds speeds of up to 900 miles per hour. In its lifetime, the Transonic Dynamics Tunnel has hosted hundreds of NASA projects, recently welcoming its latest guest, a 10-foot model of the world's most powerful rocket, the Space Launch System (SLS). SLS will send an Orion spacecraft to an asteroid and other deep space destinations on the Journey to Mars, and may also open new possibilities for robotic science m ... read more

Hues in a Crater Slope
Impact craters expose the subsurface materials on the steep slopes of Mars. However, these slopes often experience rockfalls and debris avalanches that keep the surface clean of dust, revealing a variety of hues, like in this enhanced-color image from NASA's Mars Reconnaissance Orbiter, representing different rock types. The bright reddish material at the top of the crater rim is from a co ... more

China plans probes to far side, poles of Moon
China is planning missions to explore the far side of the Moon and to send robots to explore both lunar poles. Plans to send astronauts to the Moon are also being discussed, according to Wu Yanhua, vice director of the China National Space Administration. Wu told a press conference on Tuesday that work on the Chang'e-5 lunar mission, scheduled to make a soft landing on the Moon and r ... more
