Elon Musk's plan for life on Mars

Stunning views, lots of elbow room, and complete custom living are just a few of the benefits of space settlements -- and we might just be closer to attaining them than you'd think.

Elon Musk, founder of the private space transport company SpaceX, earlier this month outlined plans for the colonization of Mars, something he says can get under way in the next 10 to 20 years with the first manned mission to the Red Planet. If the first settlement is designed to build and sustain additional settlements, colonization could proceed from there quite rapidly, he explained at the Royal Aeronautical Society in London, as reported by Space.com.

Following a first manned mission, Musk next envisions sending a small team of 10 people to Mars, along with construction supplies to build transparent domes.

Still, the process of building citylike colonies to sustain long-term habitation is expensive and challenging. Unveiling some of his planning specifics, Musk stressed the importance of a reusable rocket to keep costs down. … Read more

DOE, NASA testing fission reactor for spaceflight

Why don't we have warp drive yet? Well, because, according to "Star Trek" lore, inventor Zefram Cochrane hasn't been born yet.

Baby Zefram is due in about 20 years, but in the meantime NASA and the Department of Energy are working on something somewhat tantalizing if you're planning a deep-space probe.

Researchers including engineers from Los Alamos National Laboratory have demonstrated a nuclear reactor that could power spaceflight. It's nowhere near as powerful as NASA's conceptual antimatter engine--the Demonstration Using Flattop Fissions (DUFF) experiment produces just 24 watts of electricity. … Read more

Two space veterans named to yearlong station flight

Astronaut Scott Kelly and cosmonaut Mikhail Kornienko, both veterans of long-duration space flights, will spend a full year aboard the International Space Station to help scientists learn more about how the body reacts and adapts to weightlessness and other aspects of the space environment.

The research is aimed at helping scientists and engineers develop possible countermeasures for future manned missions to deep space destinations including the moon, nearby asteroids and, eventually, Mars.

"Congratulations to Scott and Mikhail on their selection for this important mission," William Gerstenmaier, NASA's associate administrator for space flight, said in a statement. "… Read more

NASA's not sharing a 'historic' find on Mars... yet

It seems NASA and the Curiosity rover have found something exciting and nerd-tastic on Mars, but the space agency's scientists are holding back for now, despite how painful it appears to be for them.

NPR science correspondent Joe Palca happened to be in the room recently when John Grotzinger, lead scientist for the Curiosity mission at NASA, started receiving data on his computer from the rover's on-board chemistry lab, also known as SAM (sample analysis at Mars). SAM and NASA scientists on Earth have been busy analyzing a sample of Martian soil of late, and apparently the dirt from the Red Planet has a secret to tell.

"This data is going to be one for the history books, it's looking really good," Grotzinger said in the story that aired yesterday.

And that's about all he said.… Read more

Soyuz brings three station fliers home after 127 days aloft

Three veteran space station fliers strapped into their Soyuz ferry craft, undocked and plunged back to Earth today, making a fiery descent to a frigid pre-dawn landing in Kazakhstan to close out a 127-day stay in space.

With Soyuz commander Yuri Malenchenko strapped into the descent module's center seat, flanked on the left by outgoing Expedition 33 commander Sunita Williams and on the right by Japanese astronaut Akihiko Hoshide, the crew undocked from the station's Russian Rassvet module at 5:26 p.m. EST as the two spacecraft sailed 250 miles above northwestern China.

Two-and-a-half hours later, positioned … Read more

Mars radiation fine for humans, Curiosity finds

"Now, this is the plan. Get your ass to Mars."

We all remember Schwarzenegger motivating himself to go to the Red Planet in "Total Recall" (anyone bother watching the remake?) and sure we'd like to go too. Now NASA's Curiosity Mars rover has determined that radiation levels on the planet's surface are safe for human explorers.

"The astronauts can live in this environment," Don Hassler, principal investigator on Curiosity's Radiation Assessment Detector instrument (RAD), told a news conference.

"Basically, we're finding that the Mars atmosphere is acting as a shield for the radiation on the surface and as the atmosphere gets thicker, that provides more of a shield and therefore we see a dip in our radiation dose," Hassler said.

The findings mark the first time that cosmic rays have been measured on the surface of another planet, and come 100 years after Victor Hess discovered cosmic rays on Earth by using a hot-air balloon.… Read more

Zoom around the vast Milky Way in a browser

In the grand scheme of things, it's fair to say our solar system is very tiny.

You might especially agree with that statement after viewing 100,000 Stars, a Google Chrome Experiment Web page that gives anyone the chance surf around the our slice of the universe from the comfort of their Internet browser. Spacesuit and oxygen supply optional. … Read more

Microsoft hit with lawsuit over Surface's storage space

Microsoft is being sued for allegedly misleading advertising about the amount of storage space in its new 32GB Surface tablet.

The lawsuit was brought by California lawyer Andrew Sokolowski who claims that he bought the device under the premise that he'd get 32GB of storage but soon found out it actually came with much less, according to the Associated Press.

Sokolowski's argument is true. Microsoft's Surface, which hit stores last month, is advertised as having 32GB of storage when in fact there is only 16GB of free storage space for users to fill with music, documents, and … Read more

DARPA SpaceView enlists amateur astronomers

DARPA today announced a new approach to tracking the increasing population of space debris: crowdsourcing. The SpaceView program will reach out to amateur astronomers in helping to protect satellites from what NASA estimates is more than 500,000 pieces of hazardous space debris orbiting the Earth. It's a low-cost way to both improve the scope of the space coverage and better protect assets in space, some of which are satellites providing mission-critical combat support. Decomissioned satellites, spent rocket stages, aluminum oxide slag, and lost tools make up some of the half million pieces of debris -- and the Space … Read more
