Self-repairing Aircraft Could Revolutionize Aviation Safety

A new technique that mimics healing processes found in nature could enable damaged aircraft to mend themselves automatically, even during a flight. As well as the obvious safety benefits, this breakthrough could make it possible to design lighter airplanes in future. This would lead to fuel savings, cutting costs for airlines and passengers and reducing carbon emissions too.

NASA Successfully Completes First Series Of Ares Engine Tests

NASA engineers Thursday successfully completed the first series of tests in the early development of the J-2X engine that will power the upper stages of the Ares I and Ares V rockets, key components of NASA's Constellation Program. Ares I will launch the Orion spacecraft that will take astronauts to the International Space Station and then to the moon by 2020. The Ares V will carry cargo and components into orbit for trips to the moon and later to Mars.

Bacteria Levels In Aircraft Shows Low Risk To Travelers, Study Shows

Popular wisdom says that aircraft provide the perfect environment for spreading disease, but few studies exist to confirm or deny this suspicion. Now, a team of researchers has measured concentrations of bacteria in the cabin air of 12 commercial passenger aircraft, and found that flying may be safer than we think.
