Big Hairy Ian writes "An aircraft that resembles a four-point ninja star could go into supersonic mode by simply turning 90 degrees in midair. The unusual 'flying wing' concept has won $100,000 in NASA funding to trying becoming a reality for future passenger jet travel. The supersonic, bidirectional flying wing idea comes from a team headed by Ge-Chen Zha, an aerospace engineer at Florida State University. He said the fuel-efficient aircraft could reach supersonic speeds without the thunderclap sound (PDF) produced by a sonic boom — a major factor that previously limited where the supersonic Concorde passenger jet could fly over populated land masses."

raque writes "Following up on an earlier story, a group of aviation archaeologists will use underwater robots along with submersibles and sonar to search for Amelia Earhart's plane. The International Group for Historic Aircraft Recovery will search this July for the aircraft, which went down 75 years ago. 'If there's wreckage there that can be recovered, we need to know what it is, how big it is, what it looks like, and what it's made of so we can prepare a recovery expedition that has equipment to raise whatever's there,' said Richard Gillespie, the group's executive director."

Hugh Pickens writes "Innovation News reports that the U.S. Navy plans to upgrade its robotic Fire Scouts with electronic 'brains' that are able to automatically recognize small pirate boats spotted through 3D laser imaging by bouncing millions of laser pulses off distant objects to create a 3D 'radar' image of any boats on the high seas — a technology known as LIDAR or LADAR — so that their new software can automatically compare the 3D images to pirate boat profiles on record. Having smarter robotic helicopters could ease the workload strain for Navy sailors, who must otherwise eyeball the data coming from the new Multi-Mode Sensor Seeker (MMSS) — a sensor mix of high-definition cameras, mid-wave infrared sensors and the 3D LADAR technology. Meanwhile, the Navy has begun testing other new technologies to tackle the problem of piracy — an especially thorny issue because of Somali pirates attacking ships off the coast of East Africa. Its more forceful countermeasures include a combination of lasers and machine guns, as well as swarms of smart rockets capable of picking out their own small boat targets."

Despite all the best intentions and meticulous overengineering, some of the equipment on spacecraft like the ISS inevitably breaks. An anonymous reader poses the question "Why carry out a very expensive launch into space to resupply the ISS, when astronauts could just manufacture replacement parts themselves?" Startup Made in Space is working on a space-oriented 3D printing system to make it easy to transmit the information needed to pop out complex shapes (as might be in delicate mechanical systems), but the founders are also talking about using 3D printers to jump-start construction if humans extend their presence from the Earth to other planets (or revisit the moon).

Mikkeles writes "After a grueling five-day test of material-collecting ability, the team from Laurentian University returned home to Sudbury, Canada with the win in NASA's second annual Lunabotics competition. Second place went to North Dakota, and West Virginia University placed third."
