The third batch of four satellites in the O3b medium Earth orbit (MEO) constellation, operated by O3b Networks, was successfully launched by Arianespace on December 18 from French Guiana using a Soyuz rocket.
The first four satellites have been in orbit since June 2013, while the second batch, launched on July 10, 2014. The constellation of 8 became fully operational in September. The services offered by these eight satellites are highly successful - confirming the validity of the O3b desi...
Laser ranging from Earth to NASA's Lunar Reconnaissance Orbiter (LRO) was a milestone in the 50-year history of satellite laser ranging.
Launched in 2009 and still orbiting the moon in 2014, LRO was the first spacecraft beyond Earth orbit to be routinely tracked using lasers, which were located at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and other facilities.
“The advantage of laser ranging is its accuracy, and that was apparent even in the earliest e...
The Lockheed Martin [NYSE:LMT]-built Orion spacecraft has just completed its 2,700 mile journey from Naval Base San Diego back to Kennedy Space Center (KSC). The NASA Ground Systems Development and Operations team transported the spacecraft across the country by truck, and the entire trip took eight days.
"Despite travelling a bit slower than what we're used to, Orion made pretty good time," said Michael Hawes, Lockheed Martin vice president and Orion program manager. "Most of the team hasn't...
Soyuz Flight VS10
Today's medium-lift Soyuz mission, which deployed the next four satellites for O3b Networks' pioneering connectivity service on a flight performed from the Spaceport in French Guiana, wrapped up an historic 12 months of commercial launch services for Arianespace.
The 2-hr., 22-min. flight began with the propulsion of Soyuz' basic three-stage launch vehicle, and was followed by multiple burns of its Fregat upper stage. O3b Networks' four satellites were released in two pha...
NASA and an international team of planetary scientists have found evidence in meteorites on Earth that indicates Mars has a distinct and global reservoir of water or ice near its surface.
Though controversy still surrounds the origin, abundance and history of water on Mars, this discovery helps resolve the question of where the "missing Martian water" may have gone. Scientists continue to study the planet's historical record, trying to understand the apparent shift from an early wet and warm ...
The sun fired off a massive solar flare late Friday (Dec. 19), after days of intense storms from our nearest star. The huge solar flare registered as an X1.8-class event, the most powerful type of flare possible, and was captured on camera by NASA's powe
On Oct. 31, 2014, the space tourism company Virgin Galactic suffered a serious accident during a SpaceShipTwo test flight, resulting in the loss of the spacecraft. One pilot died in the crash, while another suffered injuries. See our full coverage.
The private spaceflight company SpaceX won't be flying a mission to the International Space Station until early 2015.SpaceX is now expected to launch its fifth official mission to the orbiting outpost under a contract with NASA on Jan. 6.
The Andromeda galaxy appears to twinkle behind two stunning meteors in this skywatching image taken from Tobias Lookout near Kernville, California. Astrophotographer Casey James took this image on August 2nd, 2014.
An ambitious private space exploration project that aims to land a moon-drilling probe on the lunar surface by 2024 now has the money it needs, thanks to a crowdfunding effort that raised more than $1 million.
Kip Thorne, the physicist who brought real science to the movie "Interstellar," has a history of coming up with ideas that sound straight out of science fiction. We've rounded up three of Thorne's most mind-bending theories — at least one of which may hav
A recent payload flight by commercial balloon spaceflight company World View Enterprises captured the amazing imagery. The company will be selling "first-class" capsule seats to fly at an altitude of 100,000 feet for an hour or two.
