(AP)—The spacewalking astronaut who came close to drowning in a flooded helmet searched for clues in his spacesuit Wednesday, in hopes of understanding the unprecedented water leak.
Thrusters powered by ionic wind may be efficient alternative to conventional atmospheric propulsion technologies
When a current passes between two electrodes—one thinner than the other—it creates a wind in the air between. If enough voltage is applied, the resulting wind can produce a thrust without the help of motors or fuel.
These days, aerospace engineering is all about the light stuff: building airplanes with lighter wings, fuselage and landing gear in an effort to reduce fuel costs.
What happens to an astronaut's brain during a mission to Mars? Nothing good. It's besieged by destructive particles that can forever impair cognition, according to a UC Irvine radiation oncology study appearing in the May ...
(Phys.org)—New research by Stanford aeronautics and astronautics Assistant Professor Sigrid Close suggests she's on track to solve a mystery that has long bedeviled space exploration: Why do satellites fail?
NASA is preparing to launch a 3-D printer into space next year, a toaster-sized game changer that greatly reduces the need for astronauts to load up with every tool, spare part or supply they might ever need.
A NASA top official wrestled with what he thought was a hypothetical question: What should you tell the astronauts of a doomed space shuttle Columbia?
Are you crazy enough to sign up for a one-way trip to Mars? Applications are now being accepted by the makers of a Dutch reality show that says it will deliver the first humans to the Red Planet in 10 years.
