NASA’s Curiosity rover has taken a whiff of Martian air at the "Rocknest" site in Gale Crater. The robot explorer's Sample Analysis at Mars (SAM) instruments are now being used to measure the constituent elements of the atmosphere and their isotopes with the aim of providing insights into the history of the Red Planet and its chances of having once supported life.

SpaceX has completed the first three performance milestones for the manned version of its Dragon/Falcon 9 spacecraft and launch system. In an announcement at its Hawthorne, California, headquarters, SpaceX said that the milestones are part of NASA's Commercial Crew Integrated Capability (CCiCap) initiative, which is intended to develop privately owned and operated manned spacecraft capable of taking passengers into low Earth orbit for NASA and private customers.

ORBITEC flight tests new vortex liquid fuel rocket engine
Orbital Technologies Corporation (ORBITEC) successfully flight tested its patented vortex liquid fuel rocket engine on October 25. The engine was installed in a Prospector-class Garvey Spacecraft Corporation launch vehicle, and the resulting rocket was launched at the Friends of Amateur Rocketry facility near Edwards Air Force Base in California. The flight established substantial progress toward ORBITEC's development of a 30,000-lb (13,600-kg) thrust vortex engine for the US Air Force Advanced Upper Stage Engine Program and for NASA's Space Launch System.

NASA’s Curiosity Mars rover has completed its first soil analysis of the Red Planet. The unmanned explorer used an advanced, miniaturized X-ray diffraction instrument that is part of the Chemistry and Mineralogy instrument (CheMin) of its internal laboratory. The soil, collected at a site designated “Rocknest” in Gale Crater, reveals that Martian soil is a weathered volcanic type similar to soils found in the Hawaiian Islands. Read More
SpaceX Dragon returns from first commercial mission
History’s first commercial space mission ended today as SpaceX’s Dragon spacecraft returned to Earth. The 21-day flight to the International Space Station (ISS) ended when the unmanned cargo ship splashed down in the Pacific Ocean at 12:22 p.m. PDT. The mission, designated CRS-1, is the first of twelve SpaceX is sending to the ISS as part of NASA’s plan to replace the retired Space Shuttle with privately built and operated spacecraft that will one day carry both cargo and crew.

NASA heli-capsule could let astronauts land anywhere
Just because the world has moved on from the Space Race years doesn't mean that NASA has. Researchers from the agency are playing with new ways to guide returning space capsules back to the Earth. One possibility is the addition of helicopter-like rotors to the spacecrafts, allowing for landings just about anywhere. Read More
NASA developing atomic optics to detect gravity waves
Gravity waves are the big ticket item of physics. Predicted by Albert Einstein in 1916 as part of his general theory of relativity, these waves could help scientists solve many mysteries about the origin of the universe – if they could detect them. In an attempt to do this, researchers at Stanford University and NASA’s Goddard Space Flight Center are developing a new atomic interferometry technique that may be sensitive enough to record gravity waves for the first time.

Curiosity rover takes its first Martian soil samples
NASA’s Curiosity Mars rover took its first soil sample last week. The unmanned explorer used its robotic arm to scoop up a bit of the Martian surface, which it then sieved. A baby-Aspirin sized portion was subsequently deposited into its internal laboratory for analysis by the Chemistry and Mineralogy (CheMin) instrument, to determine what minerals it contains.

Geostationary satellites cost a fortune and, despite their sophistication, they break down or eventually run out of propellant to keep them oriented. This is unfortunate when the nearest garage is back on Earth, so NASA wants to remedy this with an orbital version of roadside service. The space agency is developing a service robot that can visit ailing satellites and refuel or even repair them on the spot. Read More
The size and age of our Universe is not only a critically important issue in cosmology, but is also among the most controversial and delicate of the cosmological questions. Infrared observations made using NASA's Spitzer Space Telescope have now given us the most precise estimate yet of the rate at which our Universe is expanding. The key was not the discovery of a new method for measuring distance. Rather, astronomers discovered how to measure brightness more accurately. The new value for the Hubble constant, good to within three percent, is 74.3 kilometers per second per megaparsec (km/s/Mpc). Read More
