In a press conference yesterday, the astronauts on ISS expressed confidence that the station will not be evacuated, and that the Russians will solve their rocket problems in time to launch the next crew by November.
A $300 laser so powerful that astronauts could see it. Safety glasses included!
The Lunar Reconnaissance Orbiter team have released new images of the Apollo 12, 14, and 17 landing sites on the Moon. Below is a cropped image of the Apollo 12 site, showing the trails left by astronauts Pete Conrad and Alan Bean when they walked from their lunar module to Surveyor 3, an unmanned lunar lander that had soft landed there two years earlier. The full image shows some incredible detail.
Some suggestions for keeping ISS occupied.
I especially like Harman’s suggestion that the Russians consider landing in the U.S. during the winter, thereby allowing them to extend one crew’s occupancy of ISS into December, January, or even February. Also, he proposes the Russians send an unmanned Soyuz to ISS during testing of the rocket, thereby providing the crews onboard a fresh lifeboat. This is something they have done in the past on their previous space station Mir.
Awakening the only British launched science satellite, dead for decades.
The launch of China’s first space station module has now been scheduled to late September.
Japan plans to test fire the engine of its failed Venus probe Akatsuki twice this month, in anticipation of another try at Venus orbit in 2015.
The riddle of ancient Roman concrete.
Bad news for commercial space: A test of Amazon chief’s Blue Origin spaceship ended in failure on Friday.
After The Wall Street Journal reported on the failure, Blue Origin Friday posted a brief note on its website stating the spacecraft, while going faster than the speed of sound, suffered a “flight instability” at an altitude of 45,000 feet and the company’s automated “range safety system” shut off all thrust and led to its destruction. The problem appeared to stem from thrusters that didn’t respond properly to the initial commands, according to one industry official.
China’s lunar probe, Chang’e 2, has reached the L2 point in space, almost a million miles from Earth.

A just released National Research Council report on space junk, Limiting Future Collision Risk to Spacecraft: an assessment of NASA’s meteoroid and orbital debris programs, describes in great and worthwhile detail the increasing problem of orbital debris as well as the technical and budgetary problems that exist for removing it. It is especially worth reading for the stories, such as when a Colorado hiker heard a high-pitched sound and then found a still warm thirty-inch diameter sphere in a foot deep crater. The object turned out to be a titanium tank from a Russian upper stage rocket, launched two months earlier.
What I want to focus on here, however, is one issue the report discusses that, as far as I can tell, has generally been missed. Worse, this issue — somewhat ridiculous when you think about a little — will make removing most of the space junk in Earth orbit far more complicated than ever imagined by engineers.
Simply put, under already agreed-to international treaties, no nation can salvage or collect any debris placed in orbit by another nation. To do so will violate international law, and almost certainly cause an international incident. To quote the report:
