A single dose of radiation approaching what will be faced by long-term space travelers to the Moon or Mars causes as much as a 39 percent spongy bone loss in mice, a new study shows. The loss of connectivity in spongy bone ranged as high as 64 pe
Former soap star Victoria Principal, designer Philippe Starck and a senior member of an unidentified royal family have all bought tickets for the world's first tourist space flights planned for 2008. Virgin Group, owned by billionaire business
Business is on the upswing for UP Aerospace—a firm that is offering suborbital rocket shots of experimental payloads out of the Southwest Regional Spaceport site in New Mexico. In an update, the firm stated over the weekend that the first launch o
For many millions of years after our universe first formed no stars existed, and then there was one. That primordial star was likely a massive blazing behemoth that burned brighter and faster than any star around today.
The free-floating spheres are set to test new concepts for "smart" satellites. Able to fly in precision formation.
An unmanned, inflatable spacecraft has beamed back the first images since it slipped into orbit and expanded itself. Genesis I sent back several photos Thursday taken by its dozen cameras showing sections of the craft, according to its builder Big
Dubbed "The Big Jump", Fournier is eyeing next month for his supersonic free fall from about 130,000 feet—roughly 25 miles above the Earth. The dive from a balloon-carried gondola is slated to take place above the plains of Saskatchewan, Ca
Thanks to a boost today from a Russian and Ukrainian rocket-for-hire company, a U.S. private space firm has sent a novel expandable module toward Earth orbit—and a step forward in providing commercial space habitats. Bigelow Aerospace of North Las
The watermelon-shaped Genesis I is a one-third scale prototype of the commercial space station to which the company eventually hopes to fly humans. Unlike the rigid aluminum international space station, Genesis I consists of a flexible outer shell
A hotel tycoon's dream of building an inflatable commercial space station is taking a step toward reality — or a reality check — with the launch of a satellite that will test the technology behind the orbital outpost. The fact-finding mission
China has successfully test-fired the engines of a new rocket that could launch its first manned mission to the moon. The engines of the new Long March C rocket are expected to make it three times more powerful than existing versions of the Long Marc
Until recently, black holes have remained hidden beneath invisibility cloaks. Whereas a lot has been known about the existence and properties of black holes from Einstein’s theory of general relativity, tangible evidence has been a recent phenomenon.
A key test of a daring yet wobbly spacewalking technique that could be used someday to repair space shuttle heat shields worked well and got good reviews from two astronauts from the shuttle Discovery, NASA officials said. The repair simulat
The container is loaded, besides the vital food, with a new exercise bicycle, an oxygen generator that will eventually allow the space station to support six inhabitants, a machine that cools the station's cabin air and a lab freezer for scientif
Embedded in the heart of a supernova remnant 10,000 light-years away is a stellar object the likes of which astronomers have never seen before in our galaxy. At first glance, the object looks like a densely packed stellar corpse known as a neutron
The public space travel business is picking up suborbital speed thanks to a variety of private rocket groups and their dream machines. Joining the mix is Blue Origin's New Shepard Reusable Launch System. It is financially fueled by an outflow
A thin plastic "starshade" shaped like a giant daisy flower could one day help astronomers observe faraway planets by blocking out unwanted light from their parent stars, a new study reports. When telescopes point to a distant planet, th
NASA's rocket scientists have a new appreciation for the out-of-this-world power of bird droppings. The orbiting space shuttle Discovery sported some whitish splotches on its black right wing edge that NASA officials said appeared to be bird drop
When the space shuttle Discovery docks with the International Space Station, some of the loudest cheers will be overseas. That's because the shuttle is the only vehicle able to deliver key components of the station over the next 4 years. Its succ
NASA signed off Monday night on a Fourth of July shuttle liftoff despite worries about a piece of foam that popped off Discovery's external fuel tank while the spacecraft sat on the launch pad. "We're go to continue with the launch count
Among the systems that would need to be hard-wired are the latches that lock the shuttle to the station; the shuttle's landing gear and the parachute that slows the ship during touchdown. "It's a number of cables because the functions
A large asteroid hurtled harmlessly past the Earth early Monday at a distance of about 269,000 miles slightly farther away than the moon. Residents with telescopes in the United States and Canada had the best view of 2004 XP14, which appeared as a
While foam falling from the space shuttle's fuel tank has garnered the lion's share of NASA's attention, the space agency's chief said on Friday it was far from being the only risk facing Discovery, which is set for liftoff from Flori
A shiny coating found on rocks in many of Earth's deserts suggest a new way to search for signs of life on Mars, scientists said today. The coating, known as desert varnish, binds traces of DNA, amino acids and other organic compounds to deser
“If we were to lose another vehicle, I would tell you right now that I would be moving to figure out a way to shut the program down,” Griffin said. “I think at that point, we’re done. I’m sorry if that sounds too blunt for some, but that’s wh
A huge "double-eye" atmospheric vortex has been confirmed to exist at the South Pole of the planet Venus. The observation was made by the European Space Agency's Venus Express during its first orbit around the planet. On April 11
The Johnson Space Center's director of engineering said that NASA has removed him from the management team for the space shuttle flight scheduled for Saturday after he expressed support for workers who questioned preparations for the flight.
In early 2004, NASA's Mars strategy of "following the water" paid off handsomely for the rover named Opportunity. Landing in Meridiani Planum, Opportunity immediately found beds of soft sandstones, much altered by acidic water long ago.
A space telescope scheduled for launch in 2007 will be sensitive enough to detect theoretical miniature black holes lurking within our solar system, scientists say. By doing so, it could test an exotic five-dimensional theory of gravity that compe
The tiny satellites were discovered by the Hubble Space Telescope last May and are believed to have been formed from the same giant impact that carved out Charon, Pluto's third satellite, discovered in 1978.
