SpaceX Unveils Fully Reusable Spacecraft That Can Carry 7 Astronauts & Land Anywhere on Earth

May 31, 2014 / / 0 Comments

SpaceX founder Elon Musk took the wraps off its next-generation spacecraft today, called Dragon V2. The key improvements are that Dragon V2 will be able to land anywhere on Earth with its propulsion system and the accuracy of a helicopter. It will also be capable of carrying seven astronauts for several days. Musk said Dragon V2 is capable of docking autonomously, and that it can land either via the propulsion system, or in the case that any engines aren’t working – deploy parachutes for a safe landing. Even after starting the propulsion system, it can afford to lose two engines and land safely – primarily because of upgraded powerful engines known as “Super Draco” thrusters. Apart from the convenience of a landing location…

The Hackers Who Recovered NASA’s Lost Lunar Photos, Wired “Sitting incongruously among the hangars and laboratories of NASA’s Ames Research Center in Silicon Valley is the squat facade of an old McDonald’s. You won’t get a burger there, though-its cash registers and soft-serve machines have given way to old tape drives and modern computers run by a rogue team of hacker engineers who’ve rechristened the place McMoon’s. These self-described techno-archaeologists have been on a mission to recover and digitize forgotten photos taken in the ’60s by a quintet of scuttled lunar satellites. The Lunar Orbiter Image Recovery Progject has since 2007 brought some 2,000 pictures back from 1,500 analog data tapes. They contain the first high-resolution photographs ever taken from behind the lunar horizon…

Arecibo Observatory Detects Mysterious, Energetic Radio Burst

April 21, 2014 / / 0 Comments

A brief, blazing burst of radio waves detected by the Arecibo Observatory could herald a turning of the tide for a peculiar class of cosmic signals. Until recently, the signals had only ever been detected by a telescope in Australia, a pattern that fueled doubts about their origin. Fewer than a dozen of these bursts, lasting for only a few thousandths of a second, have ever been reported. Called fast radio bursts, the signals are cosmic enigmas that appear to come from the very, very distant universe. But since the first burst discovery in 2007, scientists have not only wondered what kind of cosmic object could produce such a tremendously bright, short-lived radio pulse but have disagreed about whether the bursts are even celestial. …
