The Orion spacecraft may have taken less than five hours to fly into space and back, but it will take a fortnight for it to return to the Kennedy Space Center in Florida, so Lockheed Martin, builder of the capsule, is conducting tests on the fly. As the 19,650 lb (8,913 kg) capsule designed to take astronauts beyond low-Earth orbit was unloaded ashore in San Diego, California from the recovery ship USS Anchorage, Lockheed engineers were waiting to take samples of the heat shield and begin processing the flight recorders.  Read More

A new study by NASA intends to examine the detrimental effects of microgravity on the immune system, by studying the blood of rats and blue mussels over the course of a prolonged stay aboard the International Space Station (ISS). The experiments, TripleLux A & TripleLux B, will be transported to the station by consecutive SpaceX commercial resupply missions. It is hoped that the results of the study could potentially inform future treatment options for immune system deficiencies both in space and on Earth.  Read More

We tend to think that Mars is as dry as a Noel Coward comedy, but it wasn't always like that. At a press conference on Monday, NASA revealed that data from its Curiosity Mars rover indicates that the Gale Crater area that the robotic explorer has been traversing for over two years may once have been a circular lake that filled and refilled over a period of tens of millions of years.  Read More

If you think it's hard waking up after a nine-hour plane flight, imagine doing so after a space voyage of nine years and three billion miles. On Saturday, NASA's New Horizons deep space probe woke itself up from hibernation mode as it began preparations for its flyby of Pluto and its moons next July. Having traveled 2.9 billion miles from Earth and with 162 million miles to go, the signals announcing the awakening took four hours and 26 minutes to cover the distance to NASA’s Deep Space Network station in Canberra, Australia.  Read More

The Dawn spacecraft has lifted the veil on another corner of the Solar System by taking its best image yet of the dwarf planet Ceres. The nine-pixel-wide image was taken from a distance of 740,000 mi (1.2 million km) from Ceres as part of the final calibration of Dawn's science camera as the unmanned probe approaches the 590 mi (950 km) wide planetoid, which it will rendezvous with and orbit in March of next year.  Read More

Another chapter in the history of spaceflight was written today at 8:29am PST, as the EFT-1 mission ended with the splashdown of the Orion capsule in the Pacific Ocean off the coast of Baja California. Though designed to carry astronauts into deep space, the Orion was unmanned for the flight, which was planned to certify the spacecraft and test critical flight systems.  Read More

NASA reentered the field of manned spaceflight as it launched the first Orion crew capsule into space today at 7:05 am EST from Space Launch Complex 37 at Cape Canaveral Air Force Station atop a United Launch Alliance Delta IV Heavy booster on a four and a half hour flight. The capsule, which was not carrying a crew, will carry out a two-orbit flight around the Earth, which will take it to an altitude of 3,600 mi (5,800 km) before returning for a splashdown in the Pacific Ocean off Baja California later this morning.  Read More

NASA announced today that the EFT-1 mission launch has been rescheduled for 7:05 am EST on Friday. Officials at NASA, Lockheed Martin, and United Launch Alliance say the problem that finally resulted in the scrubbing of Thursday's launch of the Orion space capsule has been identified. It was a malfunction in liquid hydrogen fill and drain valves on both the port and center common booster cores used for fueling the United Launch Alliance Delta IV Heavy booster, which could not be closed properly before the launch window was exceeded.  Read More

NASA's return to manned spaceflight was delayed today as the scheduled launch of the Orion EFT-1 mission was cancelled due to a series of mishaps. Originally scheduled to lift off at 7:05 am EST from Space Launch Complex 37 at Cape Canaveral Air Force Station atop a United Launch Alliance Delta IV Heavy booster, setbacks due to the weather and equipment problems forced mission control to put off the flight beyond the launch window, which ended at 9:44.  Read More

Workers removing the original countdown clock, which will be moved to the Kennedy Space Ce...

It's one of the most famous timepieces in history that's been seen by billions of people all over the world, yet, though it's big, its name isn't Ben. It's the countdown clock at Cape Canaveral, Florida, which has sat in the foreground of historic space mission launches since it was installed in 1969 during the heyday of the Apollo program. But after almost half a century of service, NASA is replacing it with a high-tech LED version that makes its public debut on Thursday during the launch of the Orion EFT-1 mission.  Read More
