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.”

Boeing vs Boeing.

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.

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

8:38 pm

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.

The FAA has issued a draft environmental impact statement required before the agency will allow SpaceShipTwo to be launched from the Mohave Air and Space Port.

Isn’t it nice to live in a free country? The FAA has issued a draft environmental impact statement, required before the agency will allow SpaceShipTwo to be launched from the Mohave Air and Space Port.

If the Wright Brothers had had to jump through the modern bureaucratic hoops required by today’s federal government, they probably wouldn’t have gotten their airplane off the ground until after World War I.

Aviation Week looks at the launch challenges facing SpaceX over the next two years.

Aviation Week looks at the launch challenges facing SpaceX over the next two years.

Though it is very clear SpaceX has a tough schedule of launches coming up, with much of the future of American aerospace riding on their success, this article is strangely hostile to the company. There is no doubt the company has fallen behind schedule, but the list of customers who have been willing to commit to the company is quite impressive, especially considering that SpaceX literally didn’t exist six years ago.

I’ll make several predictions:

  • SpaceX will experience further launch delays.
  • SpaceX will even have one launch failure in the next two years.
  • SpaceX will nonetheless succeed, because its successes will far exceed the failures, and they are clearly offering a better product for less money.

Two Sandia National Laboratories researchers are seeking a partnership with a private company to make and sell the self-guided bullet they developed.

Investment opportunity: Two Sandia National Laboratories researchers are seeking a partnership with a private company to market the self-guided bullet they developed.

The prototype design is a four-inch long bullet with a built-in optical sensor in its nose to detect a laser beam on the target. The sensor directs guidance and control information using an algorithm and a small central processing unit that helps steer tiny built-in fins to guide the bullet. According to the Sandia lab’s computer simulations, an unguided bullet in real world conditions can miss a target that is half a mile away by almost 10 yards. With this guided bullet, however, it could strike within eight inches of a target.

Austrian skydiver Felix Baumgartner, aiming to complete a record-setting 120,000 foot dive from edge of space, successfully completed a 71,581 foot practice dive today.

Austrian skydiver Felix Baumgartner, aiming to complete a record-setting 120,000 foot dive from edge of space, successfully completed a 71,581 foot practice dive today.

From launch to touchdown, the entire test flight lasted just over eight minutes, officials said. According to Baumgartner, the toughest part of the leap was the extreme cold he experienced high up in Earth’s atmosphere. “I could hardly move my hands,” the skydiver said in a statement. “We’re going to have to do some work on that aspect.”

Baumgartner is gearing up for an even bigger leap — his so-called “space jump” — from 120,000 feet (36,576 m) this summer. The current record for highest-altitude skydive is 102,800 feet (31,333 m), set in 1960 by U.S. Air Force Captain Joe Kittinger.
