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

Cassini offers a crash course in ring world orbital mechanics
It may look as though Saturn's moon Mimas is crashing through the rings in this image taken by NASA's Cassini spacecraft, but Mimas is actually 28,000 miles (45,000 kilometers) away from the rings. ... more

New Year yields interesting bright soil for Opportunity rover
Opportunity is located on the rim of Endeavour crater, heading south along the rim. The near-term plan is to reach a valley called "Willamette" where grooves are seen in orbital imagery. Just before the holidays, the rover encountered some difficult, steep terrain. As the rover tried to advance up 20-degree slopes, the wheels began to dig up the soil and progress slowed to a near stop. ... more

Solar storms could spark soils at moon's poles
Powerful solar storms can charge up the soil in frigid, permanently shadowed regions near the lunar poles, and may possibly produce "sparks" that could vaporize and melt the soil, perhaps as much as meteoroid impacts, according to NASA-funded research. This alteration may become evident when analyzing future samples from these regions that could hold the key to understanding the history of the m ... more

China Space Plan to Develop "Strength and Size"
China wants to develop "strength and size" in its space program, a China National Space Administration official said last week. In the next five years, the country plans to speed up the development of its space program. China wants to become the first country to carry out a controlled landing of a probe on the far side of the moon in 2018. China also has plans to launch its first probe to the pl ... more

When the Arctic coast retreats, life in the shallow water areas drastically changes
The thawing and erosion of Arctic permafrost coasts has dramatically increased in the past years and the sea is now consuming more than 20 metres of land per year at some locations. The earth masses removed in this process increasingly blur the shallow water areas and release nutrients and pollutants. Yet, the consequences of these processes on life in the coastal zone and on traditional fishing ... more
