NASA has suffered budget cuts and freezes the past several years, but apparently things are looking up for the U.S. space agency. Today, NASA announced that it was creating a new organizational division geared toward investing in space technology, equipment, and exploration.

"A robust technology development program is vital to reaching new heights in space -- and sending American astronauts to new destinations like an asteroid and Mars," NASA administrator Charles Bolden said in a statement. "A top priority of NASA is to invest in cross-cutting, transformational technologies. We focus on collaboration with industry and academia … Read more

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

An unmanned cargo ship loaded with spare parts, science equipment, and crew supplies -- including ice cream treats -- rocketed into orbit Sunday and set off after the International Space Station, kicking off a new era of commercial resupply flights intended to restore a U.S. supply chain that was crippled by the shuttle's retirement.

The Dragon capsule and its Falcon 9 rocket, both built by Space Exploration Technologies, took off with a rush of fiery exhaust at 8:35:07 p.m. EDT (GMT-4), quickly climbing away from launch complex 40 at the Cape Canaveral Air Force Station.… Read more

For a mobile music player that's 100,000 times less powerful than a crummy 8GB iPod Nano, Voyager 1 is mighty awesome.

The NASA space probe was launched 35 years ago today, on September 5, 1977, three months after a new space opera called "Star Wars" hit theaters. Programmed to explore the outer planets, it has traveled farther than any man-made object since then, and is leaving our solar system for interstellar space.

With its 68-kilobyte computer memory and 8-track tape recorder, Voyager is bringing old-timey tech to the stars. It's currently some 11.3 billion miles from the sun in the heliosheath, the region where the solar wind slows down as it hits gas and dust outside our solar system. … Read more

THE WOODLANDS, Tex. -- Mercury is a world of extremes. Daytime temperature on the planet closest to the sun can soar as high as 400 degrees Celsius near the equator, hot enough to melt lead. When day turns to night, the planet's surface temperature plunges to below -150 degrees C.

But some places on Mercury are slightly more stable. Inside polar craters on the diminutive planet are regions that never see the light of day, shaded as they are by their crater rims. The temperature there remains cold throughout the Mercury day -- and during the Mercury year. Now … Read more

Happy 10th birthday, SpaceX.

On March 14, 2002, entrepreneur Elon Musk, one of the so-called "PayPal Mafia" members, launched his new company with a modest goal: to become a world leader in private space exploration.

Ten years later, SpaceX has achieved just that, especially after inking the 2008 deal that gave its Falcon 9 rocket and Dragon spacecraft the exclusive rights to take NASA's cargo to and from the International Space Station after the end of the Space Shuttle program.

But the company has had plenty of other noteworthy milestones, including its 2006 deal with NASA to … Read more

NASA has found a planet outside our solar system that looks to be an awful lot like Earth--or maybe even better, given that its climate is roughly like a balmy day in Key West.

The planet, Kepler-22b, is the first confirmed planet within the "habitable zone," meaning that liquid water could exist on the surface and support life. It is almost 2.5 times the size of Earth and 600 light years away, so you may want to start saving your frequent flier miles now if you want your great-to-the-29th-power grandchildren to have a shot at vacationing there.

Scientists estimate the temperature on the surface of the planet to be about 72 degrees, according to the Associated Press. Kepler-22b circles a star very similar to our own sun, although it does it in a slightly shorter period, with one Kepler 22-b year lasting about 290 days.

Scientists say it's likely the planet has water and land, but can't yet rule out the possibility that it is an entirely gaseous planet, which would severely limit its potential as an intergalactic vacation destination.… Read more

NASA is opting to go big instead of staying at home. The space agency today unveiled its new "Space Launch System," a meaty deep-space rocket that looks something like Saturn V on steroids.

NASA's official statement describes the SLS as "an advanced heavy-lift launch vehicle that will provide... a safe, affordable and sustainable means of reaching beyond our current limits and opening up new discoveries."

Translation: Mars, baby!

"This launch system will create good-paying American jobs, ensure continued U.S. leadership in space, and inspire millions around the world," NASA Administrator Charles Bolden said. "President Obama challenged us to be bold and dream big, and that's exactly what we are doing at NASA. While I was proud to fly on the space shuttle, kids today can now dream of one day walking on Mars." … Read more

What's a search engine geek doing in the space business? Barney Pell, CTO and co-founder of Powerset, a search technology company that was acquired by Microsoft, has for the last year been working on building a robotic spacecraft to land on the moon, as the co-founder of a new company called Moon Express. (Pell also co-founded StockMaster, which was acquired by Red Herring when I worked there.)

It turns out that Pell is an old space hack. He has a Ph.D. in artificial intelligence from the University of Cambridge and worked on the AI program for Deep Space 1, … Read more
