Asteroid That Buzzed Earth
The animation above shows the object’s movement in the sky. Each image was 20-second exposure.
Today, Monday June 27 at about 17:00 UT, asteroid designated as 2011 MD will pass only 12,300 kilometers (7,600 miles) above the Earth’s surface. Read the rest of this entry »
Robotic Lander Prototype
Before we can go to Mars, it still many years before. However, NASA continues to prepare, presenting its latest design - a very interesting lander.
The new lander is an attempt to answer the question how to construct a vehicle that successfully lands on celestial bodies without atmospheres (without bulky parachutes).

The anechoic chamber at Lockheed Martin in Fort Worth, Texas, has operated in relative anonymity since its beginning in 1987. During that time, a variety of Lockheed Martin aircraft and aircraft systems, from two versions of the F-111 to many versions of the F-16, have been tested in this electromagnetically clean environment. The latest airframe to be tested in the chamber is an F-35A.
Anechoic chambers are rooms designed to stop reflections of either sound or electromagnetic waves and to isolate the aircraft from outside radio signals. The RF absorbers on the walls, floor, and ceiling inside the chamber prevent stray internal RF reflections created for the testing from bouncing back at the aircraft. The chamber in Fort Worth is used to characterize and confirm radio frequency interactions and cooperative operation of aircraft avionics.

Although human vision is capable of perceiving objects in three dimensions (3D), we spend much of our day looking at two-dimensional screens. The latest televisions and monitors can trick us into perceiving depth, by presenting different images to our left and right eyes, but they require special-purpose glasses, or specialized large-area lenses applied directly to the screen.
Holographic 3D imaging, on the other hand, presents a ‘true’ representation of an object by exactly reconstructing the light rays that would come from that object if it were present. However, integrating color into 3D holograms has proved a challenge. Consequently, holograms are usually either monochromatic, or—as in the case of credit card holograms—colored in a way that does not correspond to the real object. Now, creating true, 3D color holograms has become possible using a technique developed by Satoshi Kawata and colleagues at the RIKEN Advanced Science Institute in Wako, Japan. Austrian company debuts revolutionary wingless aircraft
A firm from Austria, Austrian Innovative Aeronautical Technology (IAT21) has unveiled a new type of aircraft that flies without wings or rotors, at the Paris Air Show. Though not actually flown at the show, spokesmen for the new aircraft, named D-Dalus (no doubt after the tragic Greek figure Daedalus, who lost his son Icarus when his wings melted as he flew too close to the sun) claim the aircraft is capable of both hovering and flying forward as fast as a jet, all with very little noise.
The new technology is actually based on old technology; it flies by means of rotating discs surrounded by blades whose angle of attack can be altered in flight. The discs are spun by means of a conventional airplane engine. What’s new is the computer and software that controls the blades, allowing for very precise flying. The company says D-Dalus can hover next to a wall, maneuver though buildings or even lay still atop a moving bobbing ship in bad weather by pushing itself down against the deck.

The Defense Department first proposed Star Wars. Now it wants Star Trek.
Program called "100 Year Starship" was initiated by the research agency which is incorporated into the Pentagon. It assumes a plan that will allow humanity over the next century to go on a long journey into space. And it's not a trip to Mars, it is definitely too close.
The program came forward 150 candidates from the public and are reportedly among them familiar names. Interest in the project include Craig Venter, a millionaire, as well as the scientist, whose team was the first able to resolve a particular human genome map, and now is working on artificial life, and alternative fuels.

Martin Jetpack a Step to Future Transportation
There are times when human beings simply don’t take no for an answer. We’ve got two legs, two arms and a head – that’s it. There are no flippers, fins or wings connected to any of us (that I know of), yet that hasn’t stopped us from diving to the deepest depths and or soaring high above the earth. The water thing I get, because we do ok there, soaring along with the birds though, well that’s another matter entirely. Sure we have airplanes and gliders and while those machines get us up in the air, they still keep us trapped inside of an encapsulated bubble. To truly get the experience of flight we need to be exposed to the elements and feel the wind in our hair so-to-speak. Hang gliders are about the closest thing to that we’ve got, but since there’s no propulsion system we’re clearly at the mercy of the wind. Read the rest of this entry » DeepShot amazing way to go!
