A Prototype quiet supersonic aircraft developed by NASA engineers in conjunction with specialists from Lockheed Martin. To create a full version so far away, but QueSST, miniature test sample, the size of which is about 1/10 of the present plane, it was in a wind tunnel.
The prototype allowed for the simulation of the flight speed from 0.5 up to 2,000 kilometers per hour. Thanks to the Cleveland Research center Glenn tests, the developers studied the aerodynamic properties of the prototype and how it behaves from take-off, flight and landing.
NASA and Lockheed Martin are going to do a full plane, which when flying, almost no noise. For this they are working on the design of the aircraft, reducing drag. Such a development could prove to be very popular, because conventional aircraft when flying very loud noise.
To develop the QueSST going to spend another year, the Assembly will take two years, and flight tests of a full prototype of the plane should start by 2020.
Scientists have successfully trained a small group of people navigating by echolocation, that is, the method by which they communicate with each other some species, such as dolphins and bats.
One of the fundamental postulates of modern physics States that in the environment a perfect vacuum is space that does not contain any matter can not exist such a process, as friction, because completely empty space cannot act this force on objects passing through it.
Using the new collection method, scientists from Stanford University were able to identify three times more uranium from the ocean for 11-hour period than previously possible.
