Curiosity catches a mysterious flash of light on the Martian horizon.
Be assured, despite what some reports are suggesting, it isn’t an alien flashing a mirror at us. The top theory now is that Curiosity caught a reflection off a “glinty” rock.
Triumph of his will: Elon Musk’s effort to build a rocket company.
The article is long, providing incredible background details on Elon Musk’s life and how he got to be the world’s most famous rocket company president. Definitely worth a read.

An incredible collection of photos from the Edwards Air Force Base 2009 open house air show.
It includes close-ups of Scaled Composites’ WhiteKnight motherships for SpaceShips One and Two.
The competition heats up: Boeing is about to begin environmental tests on a new composite fuel tank for rockets.
Tanks made of composite materials have been a dream of space engineers for decades. Lockheed Martin tried to build them for the X-33, and their failure was essentially what killed that spacecraft. If Boeing is successful here and the composite tanks can then be put into a variety of launch rockets, the savings in weight will lower the cost of getting payloads to orbit significantly.
As the NASA lunar probe LADEE nears its planned end — where it will crash onto the Moon — the scientists running it admit that they have as yet been unable to solve its primary scientific question about levitating lunar dust.
A major goal of the mission was to understand a bizarre glow on the Moon’s horizon, spotted by Apollo astronauts just before sunrise. “So far we haven’t come up with an explanation for that,” project scientist Rick Elphic, of NASA’s Ames Research Center in Moffett Field, California, said at a media briefing on 3 April. One leading idea is that the Sun’s ultraviolet rays cause lunar dust particles to become electrically charged. That dust then lofts upwards, forming a cloud that caught the light and the astronauts’ eyes.
LADEE carries an instrument that measures the impact of individual dust particles, as well as the collective signal from smaller particles. Lunar scientists had expected a certain amount of tiny dust to explain what the Apollo astronauts saw. But LADEE didn’t find it. “We did measure a signal that indicates that the amount of lofted dust has to be at least two orders of magnitude below the expectations that were based on the Apollo reports,” says Mihály Horányi, the instrument’s principal investigator, who is at the University of Colorado. Perhaps the dust lofting happens only occasionally, he suggests, and the astronauts were in just the right place at the right time to see it.
This remains an important question. Knowing what caused that horizon glow and knowing how often it occurs is essential knowledge for any future lunar base or research station.
The launches at Kennedy, delayed because of a fire at an Air Force radar facility, have now been rescheduled.
This includes a military launch by an Atlas 5 rocket on April 10 and SpaceX’s next Falcon 9 launch to supply ISS. The Falcon 9 flight will also include an attempt to bring the first stage back to a soft vertical landing over water.
The competition heats up: Even as India successfully launched its second homemade GPS satellite today, the head of of the Vikram Sarabhai Space Centre in India announced that it will launch a test flight of a manned capsule in June using that country’s powerful GSLV rocket.
In hearings today, Pentagon officials said that they are considering building American-built engines to use on our rockets rather than buy Russian-made engines.
They could do this very cheaply if they simply allowed SpaceX to bid on all military launches.
UrtheCast has released its first image of Earth, taken from one of its cameras on ISS.
The UrtheCast (pronounced Earth-Cast) system, which was installed (not without trouble) on the International Space Station at the end of 2013, is composed of two cameras. The Theia “medium resolution” camera took this shot; the full picture has a resolution of 3200×8000, or about 25 megapixels. The high-resolution device, which will capture video, is still being calibrated.
Eventually UrtheCast plans to provide free, constant, near-real-time video of the globe from far above — that is, when it’s not being rented out to parties interested in a quick satellite snap of an area. Powerful cameras able to respond quickly to such requests are in high demand by everyone from law enforcement to disaster-relief coordinators.
Brian Binnie, the man who flew SpaceShipOne for Scaled Composites, has left that company for competitor XCOR.
It might simply be the man got a promotion, but it also might be that he knows the problems SpaceShipTwo is having and sees his chances of flying there going down. His willingness to work for XCOR instead could also be looked at as a kind of endorsement of that company’s chances of success.
The competition heats up: Six senators on Wednesday demanded the Air Force open up competition to more companies for launching its military satellites.
U.S. senators on Wednesday urged the Air Force to allow more competition in the multibillion-dollar market for launching government satellites, citing rising costs and concerns about Russian-made engines that power some of the U.S. rockets.
Lawmakers said the Air Force’s budget plan for fiscal 2015 reduced opportunities for privately held Space Exploration Technologies (SpaceX) and others to gain a foothold in a program now dominated by the two biggest U.S. weapons makers, Lockheed Martin Corp and Boeing Co.
This demand also bodes badly in an indirect way for SLS. It indicates that these senators are beginning to notice the cost benefit of competition and of using the private market. Such a realization is going to eventually leak into their peanut brains about SLS, and that will not do that program any good, especially if the new commercial private companies like SpaceX continue to show success.
