ATK to Launch Private Space Taxi by 2015 |
The aerospace company that built the solid rocket boosters for NASA’s space shuttle fleet announced plans today (May 9) to develop its own private launch system — a spaceship and rocket — to fly astronauts to and from low-Earth orbit. The first manned flight could launch in about three years, company officials said.
Utah-based Alliant Techsystems, or ATK, announced the new project here at the first Spacecraft Technology Expo, where thousands of government and industry officials have gathered to discuss innovative new technologies and the future of human spaceflight.
ATK had already been working on a new private rocket, called Liberty, which it submitted as a contender in the second round of NASA’s Commercial Crew Development program last year. Ultimately, the Liberty rocket was not selected to receive funding, but ATK continued development of the booster under an unfunded Space Act Agreement with NASA. As part of this arrangement, NASA shares its expertise in designing and testing the rocket but does not provide money for the project.
Now, ATK has unveiled plans for a complete launch system centered around the Liberty rocket. The design includes a space capsule to carry passengers to destinations in low-Earth orbit, such as the International Space Station, said Kent Rominger, vice president and program manager for Liberty.continue reading

NASA Spacecraft Detects Changes in Martian Sand Dunes |
NASA’s Mars Reconnaissance Orbiter has revealed that movement in sand dune fields on the Red Planet occurs on a surprisingly large scale, about the same as in dune fields on Earth.
This is unexpected because Mars has a much thinner atmosphere than Earth, is only about one percent as dense, and its high-speed winds are less frequent and weaker than Earth’s.
For years, researchers debated whether sand dunes observed on Mars were mostly fossil features related to past climate, rather than currently active. In the past two years, researchers using images from Mars Reconnaissance Orbiter’s High Resolution Imaging Science Experiment (HiRISE) camera have detected and reported sand movement.
Now, scientists using HiRISE images have determined that entire dunes as thick as 200 feet (61 meters) are moving as coherent units across the Martian landscape. The study was published online May 9 by the journal Nature.
“This exciting discovery will inform scientists trying to better understand the changing surface conditions of Mars on a more global scale,” said Doug McCuistion, director, NASA’s Mars Exploration Program, Washington. “This improved understanding of surface dynamics will provide vital information in planning future robotic and human Mars exploration missions.” continue reading
NASA’s Spitzer Sees the Light of Alien ‘Super-Earth’ |
NASA’s Spitzer Space Telescope has detected light emanating from a “super-Earth” planet beyond our solar system for the first time. While the planet is not habitable, the detection is a historic step toward the eventual search for signs of life on other planets.
“Spitzer has amazed us yet again,” said Bill Danchi, Spitzer program scientist at NASA Headquarters in Washington. “The spacecraft is pioneering the study of atmospheres of distant planets and paving the way for NASA’s upcoming James Webb Space Telescope to apply a similar technique on potentially habitable planets.”
The planet, called 55 Cancri e, falls into a class of planets termed super Earths, which are more massive than our home world but lighter than giant planets like Neptune. The planet is about twice as big and eight times as massive as Earth. It orbits a bright star, called 55 Cancri, in a mere 18 hours.
Previously, Spitzer and other telescopes were able to study the planet by analyzing how the light from 55 Cancri changed as the planet passed in front of the star. In the new study, Spitzer measured how much infrared light comes from the planet itself. The results reveal the planet is likely dark, and its sun-facing side is more than 2,000 Kelvin (3,140 degrees Fahrenheit), hot enough to melt metal. continue reading
NASA’s Commercial Crew Partner Boeing Completes Parachute Test |
The Boeing Company successfully completed the second parachute drop test for its Crew Space Transportation (CST) spacecraft May 2, 2012, part of its effort to develop commercial crew transportation capabilities that could ferry U.S. astronauts to and from low-Earth orbit (LEO) and the International Space Station.
A helicopter lifted the CST-100 crew capsule to about 10,000 feet above the Delmar Dry Lake Bed near Alamo, Nev. A drogue parachute deployment sequence was initiated, followed by deployment of the main parachute. The capsule descended to a smooth ground landing, cushioned by six inflated air bags. The test demonstrated the performance of the entire landing system.
“Boeing’s parachute demonstrations are a clear sign NASA is moving in the right direction of enabling the American aerospace transportation industry to flourish under this partnership,” NASA’s Commercial Crew Program Manager Ed Mango said. “The investments we’re making now are enabling this new path forward of getting our crews to LEO and potentially the space station as soon as possible.”
Boeing’s CST system is designed to be a reusable, capsule-shaped spacecraft capable of taking up to seven people, or a combination of people and cargo, to and from low-Earth orbit, including the space station. HDT Airborne Systems of Solon, Ohio, designed, fabricated and integrated the parachute system, including the two drogue parachutes. ILC Dover of Frederica, Del., designed and fabricated the landing air bag system. continue reading
Blue Origin Reveals New Details of Spacecraft Plans |
The curtain of secrecy is being raised by Blue Origin, a private entrepreneurial space group designing both suborbital and orbital vehicles.
Backed by Amazon.com mogul Jeff Bezos, the Kent, Wash.-based Blue Origin group has completed wind tunnel testing of its next-generation craft, simply called the “Space Vehicle.” It would transport up to seven astronauts to low-Earth orbit and the International Space Station. Though the company has been stingy on public information in the past, new details of the recent work have been released.
Blue Origin’s spacecraft sports a biconic shape, with its design refined by more than 180 wind tunnel tests and extensive computational fluid dynamics analysis. To help validate the spacecraft’s shape and body flap configuration, tests were recently carried out over several weeks at Lockheed Martin’s High Speed Wind Tunnel Facility in Dallas.
“Our Space Vehicle’s innovative biconic shape provides greater cross-range and interior volume than traditional capsules without the weight penalty of winged spacecraft,” said Rob Meyerson, president and program manager of Blue Origin.
The testing was conducted as part of Blue Origin’s partnership with NASA, under the agency’s Commercial Crew Development (CCDev)program, which awarded the company $22 million in 2011 to develop the vehicle. continue reading
Four White Dwarf Stars Caught in the Act of Consuming ‘Earth-Like’ Exoplanets |
University of Warwick astrophysicists have pinpointed four white dwarfs surrounded by dust from shattered planetary bodies which once bore striking similarities to the composition of Earth.
Using the Hubble Space Telescope for the biggest survey to date of the chemical composition of the atmospheres of white dwarf stars, the researchers found that the most frequently occurring elements in the dust around these four white dwarfs were oxygen, magnesium, iron and silicon — the four elements that make up roughly 93 per cent of Earth.
However an even more significant observation was that this material also contained an extremely low proportion of carbon, which matched very closely that of Earth and the other rocky planets orbiting closest to our own Sun.
This is the first time that such low proportions of carbon have been measured in the atmospheres of white dwarf stars polluted by debris. Not only is this clear evidence that these stars once had at least one rocky exoplanet which they have now destroyed, the observations must also pinpoint the last phase of the death of these worlds.
The atmosphere of a white dwarf is made up of hydrogen and/or helium, so any heavy elements that come into their atmosphere are dragged downwards to their core and out of sight within a matter of days by the dwarf’s high gravity. Given this, the astronomers must literally be observing the final phase of the death of these worlds as the material rains down on the stars at rates of up to 1 million kilograms every second. continue reading
