NASA working with students on Mars airplane concept
NASA is hard at work on designing the perfect aircraft to land on Mars. Just a couple of weeks ago, the space administration showed a new wing shape it is testing for future Red Planet-bound planes. As part of furthering these developments, NASA recently brought on a few students to help with its Preliminary Research Aerodynamic Design to Land on Mars program, otherwise known as Prandtl-m aircraft. The participants built a boomerang-shaped plane made of carbon fiber, which was then tested in an aircraft hangar and a different set of higher altitudes outdoors. Unfortunately, NASA says test flights didn't turn out as expected every time, namely due to the complexity of having an adequate launch system in place. One option, for example, was to have a radio-controlled plane that would take the research aircraft to the necessary altitude and have it be released.
NASA tests new wing shape for future Mars planes
Earlier this year, NASA Armstrong Flight Research Center's and Langley Research Center's request to get funding for the wind tunnels meant to test their new boomerang-shaped wings was granted. They believe the structure could lead to more efficient planes, even ones meant to be sent to Mars. Now, the two facilities are done subjecting a six-foot-span model of the shape they had in mind -- based on aircraft development from back in the 1930s -- to a series of wind tunnel tests. Thankfully, the results sound promising: according to NASA Armstrong chief scientist Al Bowers, the simulation proved that the wings are very stable and can maintain control even when completely stalled.
NASA prototypes a drone aircraft destined for Mars
No, you're not looking at a very sophisticated boomerang -- that may be the first aircraft to fly the Martian skies. NASA has revealed that it's building a prototype for Prandtl-m (Preliminary Research Aerodynamic Design to Land on Mars), a glider drone that would launch from a descending rover and survey landing sites for the eventual manned mission. The two-foot-long vehicle will weigh about 2.6 pounds on Earth, but Mars' gravity will reduce that to 1 pound -- light enough that the craft could travel up to 20 miles after starting at 2,000 feet above the surface.
NASA hopes to send ARES rocket-powered robot plane to Mars
While President Obama signs off on the future of space exploration, NASA is on the move, developing new ways to get a look at the fourth planet from the sun. We've seen our share of rovers (and one sweet hopper) in this space, and now the gang at the Langley Research Center is hard at work on a rocket-powered, robotic Mars-bound airplane. ARES, or Aerial Regional-Scale Environmental Surveyor, is 16.4 feet long, made from a lightweight polymer-carbon composite material, and has a wingspan of 21 feet. "A powered airplane flying a mile above the surface can obtain measurements over inaccessible parts of Mars and collect a whole bunch of data that no rover can collect," according to atmospheric scientist Joel Levine. Perhaps most exciting, the machine would be able to fly over the southern highlands, an area whose mountains, craters, and volcanoes have hindered exploration in the past. Sadly, all good things must come to an end -- and ARES is no exception. Although its flight would last for a mere two hours, it could cover over nine hundred miles of unexplored territory, collecting data on everything from chemicals and signs of water to the magnetic field in this region.
NASA planning methane-sniffing rocket plane for Mars mission
It's often been said that where there's water there's life, but NASA now looks to be seeing if the same can also be said of good 'ol methane, with New Scientist reporting that researchers at the agency have drawn up plans for a rocket plane that could one day sniff out sources of the gas on Mars. If it's given the go ahead, the plane would parachute down to Mars before being cut loose at an altitude of 1.5 kilometers, when the plane's rockets would kick it send it skimming across the Martian surface. On board sensors would then be able to detect methane at levels as low as a few parts per billion, as well as determine the source of the gas, which some speculate could be living micro-organisms. Of course, there's no indication of when that might take place, with the plane already failing to make the shortlist for NASA's 2011 Mars Scout mission.
