The Scorpion is designed as a possible replacement for the current, heavier munitions on Predator drones, or, in concert with a "Gunslinger" deployment pod (not unlike a plane-mountable version of the aerodynamic ejection pod seen above) as a way retrofit heavier larger, typically less-armed planes with laser-guided bombing capabilities. Despite being years into the development process (these internal videos date back to 2006), Lockheed hasn't secured any buyers yet. And yeah, as far as weapons technology goes, the Scorpion is a relatively minor upgrade. But what isn't at all minor in the number of times I've watched these videos today, each time expecting an explosion, and never, ever getting it. [Danger Room]

The modest distance (and height of about 5 feet) isn't a bad start in human-powered flight for a do-it-yourselfer. Dutchman Jesse van Kuijk hopes to go further in the future, without the bike chain powering his propeller slipping off its cog.

Though he's never flown in a real plane, Jesse says he studied self-powered craft like the Gossamer Condor and the English-Channel crossing Gossamer Albatross. He also got tips from the Albatross' pilot, American Bryan Allen, who is now a software engineer for the Mars exploration project.

The Sanswire-TAO STS-111 is a 111-foot long, 11-foot tall multi-segmented, non-rigid airship. The design of this ultralight UAV—Unmanned Air Vehicle—allows it to fly on its own for extremely long period of times. It uses gas-cell power for propulsion and electricity generation.

Why do we want these air worms? They will be able to provide people on the ground with communication networks, and also serve as terrain vigilantes. Because that's what we want up there: Giant worms watching over us. Preferably ones that can spew acid, and have laser cannons. [Sanswire via Flight Global]

The image above comes from Aeronvironment, and shows what it wants the prototype in the video below to ultimately look like. DARPA's goal is to have a 10 gram aircraft with a 7.5-centimetre wingspan. They want it to get into tight hiding spaces and send back GPS and image data.

Aeronvironment's progress is also notable because such robots previously couldn't carry their own batteries, and had to use guide wires.

"It is capable of climbing and descending vertically, flying sideways left and right, as well as forward and backward, under remote control," says the company.

Sikorsky Chief Test Pilot Kevin Bredenbeck maneuvered the prototype for 30 minutes in a few basic tasks: hover, forward flight and hover turn. The project is coming slowly into final shape but when finished, it will be able to cruise easily at 250 knots while maintaining the same features of traditional helicopters, like low speed handling, hovering, and autorotation.

The concept for the project came about through a $1.7 million "Phase One" brainstorming contract. Apparently unaware of the existence of birds, DARPA decided that this innovative and classy new idea was worth pushing through to development and handed over the second wad of cash this week. The Nano Air Vehicle is part of an apparent trend toward smaller and smaller UAVs, following AreoVironment's 80 gram, six inch Black Widow and Prox Dynamics' four inch, 20 gram Black Hornet (which, thanks to the less literal-minded people at PD, does not fly like an actual insect).

Kizuna is expected to go live in July following a setup process once it is in position, but a speed boost is not the only aim of the game. Having a satellite in space means natural disasters on Earth are not going to have any ramifications on the country's connectivity, which can be imperative in disaster zones. If all should go well, expect such an infrastructure to hit the mainstream. Does that mean everyone will have a 1.2Gbps connection? Will outages become a thing of the past? Does Simba eventually become a good leader? The answers come in July, when the service rolls out. [JAXA via Yahoo News; AP]

The Russian half of the station is stuck with the old latrine. They'll have to continue to load up one of their unmanned cargo vessels with boxes of their leftovers and send it to burn up in the atmosphere, which is pretty much the equivalent of flushing right now in space.

The new toilet should be familiar to the crew as it is similar to the hole 'n hose model the station has employed since 2000, but it is designed to allow for more privacy. As water is notably scarce in orbit, the ability to generate an onboard source of it is very important. The US-made filtration system separates water molecules from waste by not letting anything larger than tiny water molecules through.

The fancy new space toilet comes as part of a $46 million upgrade package purchased by NASA. So far, the single toilet on the Russian half of the station is responsible for the crew of three. As the crew size will double to six in 2009, NASA no doubt saw the need for a additional toilet. Six people, one bathroom? Think the Brady Bunch, but in space. If Marcia takes too long dolling it up for the cosmonauts, Jan doesn't bang on the door and yell. She jettisons her.
