On December 8, SpaceX became the first commercial company in history to re-enter a spacecraft from Earth orbit. SpaceX launched its Dragon spacecraft into orbit atop a Falcon 9 rocket at 10:43 AM EST from Launch Complex 40 at the Cape Canaveral Air Force Station in Florida. The Dragon spacecraft orbited the Earth at speeds greater than 7,600 meters per second (17,000 miles per hour), reentered the Earth's atmosphere, and landed just after 2:00 PM EST less than one mile from the center of the targeted landing zone in the Pacific Ocean. This marks the first time a commercial company...

Washington - NASA's Voyager 1 spacecraft has reached the outer edge of the solar system where wind from the Sun is no longer blowing outward, but sideways, the US space agency said. The spacecraft was launched in 1977 and has since snapped images of Earth and other planets in the solar system and provided NASA with crucial information as it makes its long journey into outer space. NASA researchers think Voyager 1 will leave the solar system and enter interstellar space, or the area in between the end of the Sun's influence and the next star system, in about four

VANDENBERG AIR FORCE BASE, Calif. (AP) - The U.S. Air Force's secrecy-shrouded X-37B unmanned spaceplane returned to Earth early Friday after more than seven months in orbit on a classified mission, officials said.

Boeing today announced the successful de-orbit and landing of the Orbital Test Vehicle (OTV), also known as the X-37B, for the U.S. Air Force Rapid Capabilities Office (RCO). The X-37B, shown here in a photo from before its launch, landed at 1:16 a.m. Pacific time today, concluding its more than 220-day experimental test mission. It was launched from Cape Canaveral Air Force Station, Fla., on April 22.

After bidding farewell to more than 1,900 space vehicles, Vandenberg Air Force Base has worked to instead get ready to greet one very high-profile spacecraft. The X-37B Orbital Test Vehicle, the Air Force’s unmanned miniature space shuttle, is scheduled to land as soon as Friday morning at Vandenberg’s 3-mile-long runway. “This is a historical first, not only for Vandenberg Air Force Base but also our Air Force and our nation to receive a recoverable spacecraft here and really take a step forward for unmanned space flight,” said Col. Richard Boltz, 30th Space Wing commander. Launched from the East Coast in...

As NASA's two Voyager spacecraft hurtle towards the edge of our solar system, a new project manager will shepherd the spacecraft into this unexplored territory: Suzanne Dodd, whose first job at NASA's Jet Propulsion Laboratory in Pasadena, Calif., involved sequencing science and engineering commands for Voyager 1 and 2 in 1984. "I'm thrilled to re-join a pioneering mission that set up adventures for so many other spacecraft to follow," Dodd said. "There will be more firsts to come as we gather unique data once the spacecraft reach interstellar space. There isn't a single mission currently on the books that will...

SNIPPET: "The probe plans to test technology in preparation for an unmanned moon landing in 2012, with a possible manned lunar mission to follow in 2017. China’s other space plans include the launch of the first module of a future space station next year followed by the dispatch of manned spacecraft to dock with it."

Ten years ago, NASA researchers discovered that the Pioneer 10 and 11 spacecraft had fallen slightly behind course during their 35-year journeys to the outer reaches of the solar system. In what has become known as the Pioneer anomaly, which was the subject of one of the talks this weekend at the American Physical Society here in St. Louis, nobody knows for sure why it happened. It probably stemmed from leaking gas or heat. But there's also the possibility, however remote, that gravity doesn't behave the way we expect. Until recently, researchers haven't had the data to distinguish the different...

When scientists send their spacecraft across the universe, they save fuel by performing “slingshot fly-bys”. This is where, rather than firing up the thrusters, the craft changes its trajectory by harnessing the enormous gravitational pull of a planet. However, this trick has had an unexpected side-effect: it seems to produce a change in speed that no one, since it was first discovered in the early 1990's, can account for. Experts are intrigued by the fact that while the acceleration is tiny and has no significant effect on NASA missions, it holds great interest because no explanation based on conventional physics...

The Russian space agency, Roskosmos, is putting the finishing touches to the design of a spacecraft, which could carry the nation's cosmonauts into space in the coming decades. Russian officials revealed details about the craft at the Farnborough Air Show. The work is a culmination of a multi-year effort to define the architecture of a replacement to Russia's 40-year-old Soyuz spacecraft. With the upcoming retirement of the US space shuttle, Russian ships could, for several years at least, be the only means of taking humans into space. This would include any American and European astronauts travelling to the International Space...

MOJAVE, Calif. (AP) -- A company working to send tourists on suborbital flights says it has tested its spacecraft with a crew for the first time. Virgin Galactic says the craft remained attached to a specially designed airplane throughout a six-hour flight over California's Mojave desert Thursday....

NASA's plucky Voyager 2 spacecraft has hit a long-haul operations milestone - operating continuously for 12,000 days. For nearly 33 years, the venerable spacecraft has been returning data about the giant outer planets, and the characteristics and interaction of solar wind between and beyond the planets. Among its many findings, Voyager 2 discovered Neptune's Great Dark Spot and its 450-meter-per-second (1,000-mph) winds. The two Voyager spacecraft have been the longest continuously operating spacecraft in deep space. Voyager 2 launched on August 20, 1977, when Jimmy Carter was president. Voyager 1 launched about two weeks later on Sept. 5. The two...

For spacecraft that zoom through the cosmos at thousands of miles per hour, calculating which one is traveling at the fastest speed is more complicated than simply clocking the first to cross the finish line. When space agencies calculate and establish speed records, these numbers need to be defined and qualified, because there can be more than one frame of reference. In other words, the speed of a spacecraft can be calculated relative to the Earth, the sun, or some other body. The record for the highest speed at which a spacecraft has launched and escaped from Earth's gravity is...

A recent United States Air Force scramjet test has hinted at a future where hypersonic vehicles streak through the sky at many times the speed of sound around the world, and perhaps even open up access to space. The experimental X-51A Waverider used a rocket booster and an air-breathing scramjet to reach a speed of Mach 5 and achieve the longest hypersonic flight ever powered by such an engine on May 26. That technology might not only deliver cargo quickly to different parts of the globe, but could also transform the space industry and spawn true space planes that take...

A group of astronomers from NASA, the Japan Aerospace Exploration Agency (JAXA) and other organizations had a front row seat to observe the Hayabusa spacecraft's fiery plunge into Earth's atmosphere. The team was aboard NASA's DC-8 airborne laboratory, packed with cameras and other imaging instruments, to capture the high-speed re-entry over an unpopulated area of central Australia on June 13, 2010. The Japanese spacecraft has been on a seven-year journey to return a sample of the asteroid Itokawa.

"Some UFOs are intelligently controlled extraterrestrial spacecraft, and this is the biggest story of the millennium." These words are not the rantings of a deranged individual looking for attention or a comfortable straitjacket. Stanton Friedman is a maverick of sorts. Employed for 14 years as a nuclear physicist for companies like General Electric, General Motors, Westinghouse and Aerojet General Nucleonics, he worked on highly classified programs involving nuclear aircraft, fission and fusion rockets. In 1958, UFOs caught his attention, and Friedman has since lectured about this subject at more than 700 colleges and professional groups in all 50 states and...

The U.S. Air Force's secretive X-37B space plane may eventually get some company in low-Earth orbit as other countries such as Italy and Russia push forward with plans for their own reusable winged spaceships. Italy's prototype space plane, named Pollux, successfully carried out high-speed maneuvers that slowed it down from a falling speed of Mach 1.2 during a test flight in April. More recently, Russia has begun considering whether to revive a Cold War era, air-launched mini-shuttle in response to the U.S. X-37B space plane debut. Such efforts may not immediately lead to full-fledged operational flights. But in the case...

In late 1960s- early 1970s the United States began works on studying of feasibility of using the outer space for performing combat activities in space and from space. The Government of the USSR by a set of Decrees (first one issued in 1976) assigned domestic activities in this field to a group of organizations-developers led by Energia NPO. During 1970s - 1980s the complex of research was performed to determine possible ways of creation of space means, capable of solving tasks of striking spacecraft of military destination, ballistic missiles in flight, as well as particularly important airborne, sea-borne and ground-based...

While the U.S. Air Force is mum about the orbital whereabouts of its X-37B mini-space plane, a dedicated band of amateur skywatchers has got its cross-hairs on the spacecraft. The unpiloted X-37B Orbital Test Vehicle 1 was lofted on April 22 atop an Atlas launcher. It is being flown under the auspices of the U.S. Air Force Rapid Capabilities Office. In U.S. military tracking parlance, when the space plane reached orbit it became identified as Catalog Number 36514, 2010-015A, OTV-1 (USA 212). From there it entered a cone of silence regarding any on-orbit duties. But thanks to a worldwide eyes-on-the-sky...

A small army of workers quickly gave the Vandenberg Air Force Base runway a makeover in readiness for an unmanned spaceplane’s landing. Military officials called the recent runway hardware retrofit a necessary step to prep for the planned landing of the X-37B Orbital Test Vehicle. The unmanned reusable spacecraft launched aboard an Atlas 5 rocket from Cape Canaveral Air Force Station in April. At the time, officials said X-37B — with a wingspan of nearly 15 feet, a length of 29 feet and height of less than 10 feet — could spend up to nine months testing technologies in orbit...
