Unlike an earlier test where one fairing did not release, a second test of Orion’s shroud separation system was successful this week.
A Texas-based company has printed the first 3D-printed metal pistol, a 45 caliber Model 1911.
Video below the fold. The gun clearly functions, though I noticed that in the video they never loaded more three rounds in a magazine, and that the gun seems to cycle weakly. I suspect that they had some feeding problems when they tried to fire a full loaded five round magazine.
Nonetheless, this achievement further illustrates that 3D printing is about to become a major method of manufacture.

Successfully growing crops in the desert using salt water and solar power.
The heart of the SFP concept is a specially designed greenhouse. At one end, salt water is trickled over a gridlike curtain so that the prevailing wind blows the resulting cool, moist air over the plants inside. This cooling effect allowed the Qatar facility to grow three crops per year, even in the scorching summer. At the other end of the greenhouse is a network of pipes with cold seawater running through them. Some of the moisture in the air condenses on the pipes and is collected, providing a source of fresh water.
One of the surprising side effects of such a seawater greenhouse, seen during early experiments, is that cool moist air leaking out of it encourages other plants to grow spontaneously outside. The Qatar plant took advantage of that effect to grow crops around the greenhouse, including barley and salad rocket (arugula), as well as useful desert plants. The pilot plant accentuated this exterior cooling with more “evaporative hedges” that reduced air temperatures by up to 10°C. “It was surprising how little encouragement the external crops needed,” says SFP chief Joakim Hauge.
The technology development here is wonderful, but it is unclear from the article whether these crops would be competitive on the open market with ordinary farm crops. The cost for this operation is not outlined.
The competition heats up? Beyonce might beat Lada Gaga into space.

Engineers successfully completed Mangalyaan’s second engine burn yesterday, raising its orbit to just under 25,000 miles.
Each one of these burns demonstrates the reliability of the spacecraft.
India’s Mangalyaan Mars probe has successfully completed its first orbital engine burn.
Not only was the burn successful, it demonstrated that the probe’s thrusters work as planned, which means it is almost certainly not going to be stranded in Earth orbit and will at least get to Mars.
Worlds without end: The number of candidate exoplanets found by Kepler has now risen to 3,500.
According to this new analysis, researchers estimate about 70% of stars are host to at least one planet, making planets a common cosmic occurrence. There are now 1,750 candidates that are super-Earth-size or smaller, and 1,788 are Neptune-size or larger. Only 167 of the 3,538 candidates are confirmed to be planets, but Kepler has a good track record: the vast majority of these are probably real.
Two dozen of these candidates are in the habitable zone, ten of which are thought to be close to Earth-sized.
Hubble spots an asteroid spout six comet-like tails.
Astronomers viewing our solar system’s asteroid belt with NASA’s Hubble Space Telescope have seen for the first time an asteroid with six comet-like tails of dust radiating from it like spokes on a wheel. Unlike all other known asteroids, which appear simply as tiny points of light, this asteroid, designated P/2013 P5, resembles a rotating lawn sprinkler. Astronomers are puzzled over the asteroid’s unusual appearance.
The competition heats up? According to People magazine, Lady Gaga will take a Virgin Galactic suborbital flight in 2015 and thus beat Sarah Brightman into space.
