Stephen Hawking predicts end-of-Earth scenario

Stephen Hawking, one of the world's greatest physicists and cosmologists, is once again warning his fellow humans that our extinction is on the horizon unless we figure out a way to live in space.

Not known for conspiracy theories, Hawking's rationale is that the Earth is far too delicate a planet to continue to withstand the barrage of human battering.

"We must continue to go into space for humanity," Hawking said today, according to the Los Angeles Times. "We won't survive another 1,000 years without escaping our fragile planet."… Read more

Sex in space may be dangerous, study says

I've always imagined that being up in space isn't really so much fun.

Yes, the views are nice, but the claustrophobia must be entirely stifling. What are you supposed to do up there, for days on end? You can't just work all the time.

The temptation, then, might be to occasionally enjoy a little recreation in the procreative sphere.

Sex would surely offer a touch of vigorous exercise and a little human community.

However, now research has emerged suggesting that sex up there could be dangerous.… Read more

Inside the SpaceX Dragon capsule (panorama)

Get a feel for what it's like inside the Dragon capsule by panning around the panorama image below.

SpaceX CRS-2, loaded with more than 1,200 pounds of supplies, including science equipment and spare parts en route to the International Space Station, lifted off this morning aboard a Falcon 9 rocket from Cape Canaveral Launch Complex 40 in Florida.

Just after the carrier rocket delivered the Dragon capsule into its target orbit, however, a problem arose. As the Solar Array was set to be deployed, which is necessary to provide enough energy to reach the ISS, a problem was … Read more

Moon to become next hot vacation destination?

I feel sorry for all those suckers who blew $20 million and only got a lousy trip to the International Space Station. If they had held out, they might have had an opportunity to invest many more millions on a trip to the moon.

Golden Spike Company announced yesterday a venture to launch commercial voyages to the moon by 2020. Of course, this sort of experience doesn't come cheap. Golden Spike is expecting a trip to cost $1.5 billion per flight. … Read more

Motorcycle gets spacecraft propulsion parts

Testing spacecraft components is no cake walk. It's expensive and can require subjecting them to tremendous amounts of stress and wear and tear, but it's necessary. You can't just blast them up into suborbit and hope they work.

Spacecraft manufacturer XCOR decided to get a little more grounded when it came to testing out components of its new piston pump technology destined for the Lynx Suborbital Spacecraft.

XCOR modified a Triumph motorcycle with propulsion parts and sent it off on a massive road trip from Roswell, N.M., to Mojave, Calif.… Read more

Manned space travel, from Gagarin to SpaceX

The anniversaries this week of the first man in space and the launch of NASA's first space shuttle missions come at time when commercial spacecraft are ushering in a new era of space flight.

Thursday was the 51st anniversary of Yuri Gagarin's 108-minute orbit around the Earth, an event that shocked the world and ratcheted up the speed of the Cold War-fed space race.

And 31 years ago on April 12, the space shuttle Columbia lifted off, the inaugural flight of NASA's shuttle program which drew to a close last year.

Astronauts from different countries on the … Read more

Watch SpaceX test-fire its new engine...on the ground in Texas

Brace yourself, pyromaniacs. Put away all the matches before you watch the below video of SpaceX's new SuperDraco engine spewing flame.

Elon Musk's space exploration company released the video of a successful test-firing of an engine from a test site in McGregor, Texas. The SuperDraco could be used to propel SpaceX's Dragon spacecraft out of Earth's gravitational pull, and Musk claims it will be the safest such system in history and also capable of more accurate landings. As if to prove the point, there are plenty of completely flammable trees in the background of the test-fire site in the video.… Read more

Fill 'er up at an interstellar gas station

A spaceship isn't much use if it doesn't have the juice to go somewhere. And if you're an astronaut bouncing around destinations like the moon, random asteroids, Lagrange points, and Mars, you'll probably need an interstellar gas station.

NASA has launched an "In-Space Cryogenic Propellant Storage and Transfer Demonstration Mission Concept (PDF)" study, which is essentially a call for scientific institutions around the globe to help create a space gas station. Those wishing to build a fueling stop in the sky have until May 23 to submit their proposals.

Cryogenic propellants used in rocket engines are usually made of liquid hydrogen and liquid oxygen. Both liquids reside in enormous insulated containers and are pumped through an expansion chamber, then mixed and ignited in the combustion chamber. The result is an incredible amount of power per gallon of cryogenic proellant, up to 40 percent higher than other rocket fuels.

However, there are many challenges to creating a gas station in the stars. The primary objectives of the study are to address key elements including a fail-safe way to transfer the propellants from a storage container to a ship. The difficulty is high since hydrogen tends to leak (it's the smallest element), and can eventually deteriorate the container it's stored in. … Read more

The city that must vote on UFO ballot measure

Somehow, with all the strange, otherworldly people standing for office in American elections Tuesday, one ballot measure has not received quite the enormous importance that it deserves.

No, I am not thinking of Proposition 19 in California, the one supported by significant members of the tech world, the one that hopes to legalize the sale of marijuana.

This ballot measure, addressed to voters in Denver, is called Initiative 300 and it is adorned by perhaps the most ridiculous question ever asked in a political campaign: "Are you ready for the truth?" The truth that proponents of this measure … Read more

Bartender, gimme a beer from outer space

Is all this space travel worthwhile? Will it really contribute to our civilization or our touchingly naive way of life? Will it even lift our spirits?

I cannot be sure about the first two, as I feel these might be permanently floating somewhere out there. But I have some space-sourced spirit lifting to share.

Japan's Sapporo Breweries, the entity that brings you those large silver tins of beer to complement your rainbow roll, announced this week that it is launching space beer.

According to Reuters, Sapporo "Space Barley", with its cute outer-space sparkling starred label, has been … Read more
