NASA Building A Prototype Deep-Space Habitat In Texas

Living in the deep reaches of outer space, in Texas. Via Popular Science:

It’s not going to send anyone to deep space. But it does give us a tantalizing look at what it’ll look when NASA does take the next steps in space travel.

Engineers at Marshall Space Flight Center and experts Johnson Space Center in Houston are tinkering with the spaceship mockup, deciding the right size, necessary equipment, and everything else that’s going to make a mission to Mars, a near-by asteroid, or the second Earth-Moon Lagrangian point (277,000 miles away from Earth) as pleasant as possible.

The team’s also planning what [devices] will be sent along and built in. One is a 3-D printer, which would allow astronauts to create any tools they need right on the spot. There’s also greenhouse for astronauts to grow their own and food, and a barrier of water on the outside that could be used to shield explorers from cosmic rays.

Asteroid Travels Close To Earth Today

Sometimes asteroids come very close to home, about every six years. The latest asteroid to come closer to Earth than our own satellites appears today. Via Space.com:

An asteroid the size of a tour bus will fly past Earth today (June 27) so closely it will be beneath some of the planet’s satellites.

The rock, named asteroid 2011 MD will zoom by just 7,500 miles (12,000 km) above the planet, making a sharp turn forced by Earth’s gravity before winging off into space again. The flyby will occur at about 1 p.m. EDT (1700 GMT).

There is no risk of an impact, NASA scientists said. The space rock, estimated to be between 29 to 98 feet (9 to 30 meters) wide, is likely too small to survive a plunge through our atmosphere anyway. An asteroid this size, if it were mostly stony, would break apart and burn up before hitting the surface.
