Ten amazing treetop walkways from around the world.
French engineers have designed a tiny ion motor that nano-satellites could use as a thruster to adjust their orbits.
Swiss engineers have designed a tiny ion motor that nano-satellites could use as a thruster to adjust their orbits.
The motor weighs only seven ounces, and could work on satellites as small as four inches cubed.
Up to now, it wasn’t possible to reduce the size of maneuverable satellites below a certain point because of the size of their large thruster engines. If it is now possible to provide nano satellites with thrusters, it will be possible to significantly reduce the cost, and more importantly, the payload weight, of satellites. And with a lower payload weight, it will be possible to create a market for smaller rockets, which are much easier to build and far cheaper.
This kind of news makes me more confident that the new commercial space industry truly has a future.

I don’t know what Bolden can do about this, however, as we don’t have the ability to get to our own space station, while Europe and the Chinese do.

This news item illustrates the sad state of the American space program, when the arrival at a museum of a foot-high plastic toy that had been in space merits major news coverage. Worse, if we instead wanted to bring this toy back to ISS, we can’t, at least not without begging help from someone else.

A toy company has designed building blocks that make it possible to combine multiple building block brands, from Legos to Tinkertoys.
By downloading free designs and using a 3D printer, you could have your very own pieces to connect ten different brands of building toys to each other and construct even more elaborate contraptions and structures.
As the first commenter on the webpage noted, “This is the next singularity.”

What’s really cool is how the driver is able to drive while holding his camera overhead through his sun roof.

Boeing vs Boeing.
The story describes how Boeing is considering upgrading the X-37B to become a manned ferry to ISS, thus putting it in direct competition with the company’s other manned capsule, the CST-100.
At the American Institute of Aeronautics and Astronautics’s Space 2011 conference in November, Boeing’s Arthur Grantz revealed that the company is studying a new derivative of the Boeing/USAF X-37B. The new X-37C would be 65-80% larger than the current B version. Launched by an Atlas V rocket, X-37C could carry pressurized or unpressurized cargo or 5-6 astronauts. Grantz is chief engineer in charge of X-37 at the Boeing Space and Intelligence Systems Experimental Systems Group .

James Cameron has set a new record for the deepest solo dive, a depth of 35,756 feet.
And he is still down there at this moment.
Hovering in what he’s called a vertical torpedo, Cameron is likely collecting data, specimens, and imagery unthinkable in 1960, when the only other explorers to reach Challenger Deep returned after seeing little more than the silt stirred up by their bathyscaphe. After as long as six hours in the trench, Cameron—best known for creating fictional worlds on film (Avatar, Titanic, The Abyss)—is to jettison steel weights attached to the sub and shoot back to the surface. Meanwhile, the expedition’s scientific support team awaits his return aboard the research ships Mermaid Sapphire and Barakuda, 7 miles (11 kilometers) up.

Last night a piece of space junk missed ISS, but not by much.
The debris was only 8.7 miles from the station when it zipped by at about 16,000 miles per hour. That is very close, and had it hit, it would have done very significant damage.
The fragment was from an old Russian satellite, Cosmos 2251, that collided with an Iridium satellite in 2009, producing hundreds of fragments more than two inches across.

In discussions the last two days managers for the space programs of Europe and China began laying the groundwork for a Chinese docking at ISS.
In discussions the last two days, managers for the space programs of Europe and China began laying the groundwork for a Chinese docking at ISS.
The United States, which paid for and built the bulk of ISS, has no way of getting its own astronauts to the station. The United States at present also has no way to bring cargo up to the station.
The result: We no longer own our own space station. Though the U.S. has strict laws on the books to prevent the transfer of technology to the Chinese, restricting communications by government officials with China, the Europeans do not. And since they can send cargo to ISS while we cannot, they feel free to negotiation with the Chinese for the use of our space station. Moreover, the Russians I am sure will heartily endorse these negotiations.
And what can the U.S. government do? Nothing.
Instead of focusing on a solution to this situation, the members of Congress tasked with supervising NASA want NASA to build a giant heavy-lift rocket (SLS) to use with the Orion capsule, neither of which is designed to go to ISS. Moreover, neither will be capable of flying humans into space until 2021, one year after ISS is presently scheduled to be shut down. Even then a single flight will cost billions, which makes this system useless for resupplying ISS.
And people wonder why I consider these elected officials stupid. And if they aren’t stupid, they surely are irresponsible and incompetent, at least when it comes to the American space program.

Europe successfully launched its third unmanned freighter to ISS early this morning.
The 13-ton cargo freighter is loaded with about 7.2 tons of supplies, including food, water, clothing, experiments and fuel for the space station, according to NASA. The unmanned ATV-3 is the heaviest load of cargo ever delivered to the station by a robotic spacecraft, ESA officials said in a statement.

Stupidity on display
In hearings Wednesday, several members of Congress suggested that NASA force the new competing commercial space companies to combine their efforts in order to save money.
Rep. Frank Wolf (R-Va.) asked NASA Administrator Charles Bolden during a March 21 hearing on the agency’s 2013 budget the same question he asked of the White House’s chief science adviser last month: would NASA’s partnership with commercial companies to develop astronaut transports be cheaper if the companies competing for NASA funds combined their efforts into a single “all for one and one for all” project?
Similarly, Senator Kay Bailey Hutchison (R-Texas) made the same stupid argument in her continuing effort to keep the funding of the Space Launch System, the rocket-formerly-called-Constellation, as high as possible, at the cost of cutting everything else in NASA if necessary.
If you needed any evidence that members of Congress are ignorant idiots, you only need read the comments of these elected officials at these hearings to get your proof. Wolf or Hutchison as well as several others from both parties very clearly haven’t the slightest idea what these various space companies are building. Nor do they have the faintest notion of the difficulties entailed in building these manned space vessels.
