NASA has tested the supersonic parachute in Hawaii

June 28, NASA tested the LDSD , which stands for Low Density Supersonic Decelerator . Behind this statement a new type of parachute lies “supersonic“, much larger than those currently in use. The project is aimed at exploration missions to Mars to allow the landing of heavy loads (and delicate), on the surface of the Red Planet are not enough conventional parachute, a technology tried and tested but no longer in step with the needs ( it is, moreover, for projects in the 70’s). For the experimental launch was used the U.S. Navy’s Pacific Missile Range Facility, near the island of Kauai, Hawaii , at 8.40 local.

LDSD has a length of 30.5 meters, and is paired with two devices similar to flying saucers, the Supersonic Inflatable Aerodynamic decelerators (SIADs). One of the SIAD is 6 meters wide, while the other measures 8 meters. The vehicle used for the test (with a weight of 3.175kg) was attached to a balloon filled with helium, which rose up to 36.5 kilometers high into the stratosphere. At this point the vehicle is off the ball, and used its thrusts to go up to 55 km, reaching a speed of Mach 4 (four times the speed of sound). The altitude was chosen to simulate the Martian atmosphere, which is only 1% denser than the Earth, at sea level.

In return phase to the surface, the SIAD would have to swell and slow the vehicle test, making it off the speed at Mach 2.5, with the subsequent intervention of the parachute, which would have allowed a safe splashdown in the Pacific Ocean. During the tests, however, the system did not work perfectly : the SIAD is inflated correctly, but the parachute did not open properly.Despite all the landing was successful (at 23.40 Italian time). The scientists were satisfied: the test is not carried out properly are still considered very valuable, because they allow to understand the mistakes.

Google Glass New Version Coming with 2GB Ram

Ready for the third version of the Google Glass? After introducing 2.0 V with external headphones, here is Google preparing commercialize third hardware revision for Google Glass. In particular, we talk about 2GB of RAM for the new glasses that will be distributed in the coming days.

There seem to be changes at the level of the CPU even if the version Explorer is unlikely to have the processor currently used. Do not miss an update with several new software that you can find in the press release below:

Microsoft: New Anti-Theft Measures for the Protection of Windows Phone

Microsoft has officially announced today’s in important details on a series of measures that will be introduced to improve software security aspects of Windows Phone smartphones in the event of theft.

The “Find My Phone” Windows Phone, more specifically, will provide the appropriate functions for:

  • Remotely wipe personal data stored on your smartphone
  • Make your smartphone unusable by unauthorized users, who can only make emergency calls
  • Prevent reactivation or the setup of your smartphone without the permission of the authorized user
  • Reverse the system in case of recovery of smartphones and enable restoration of data stored in the cloud if your smartphone was deleted

It is, therefore, a series of important options that, in fact, make the device unusable in possession of the thief, allowing at the same time to restore the correct operation of the terminal in case of finding.

The features described above will be made available in the form of software update intended for all smartphone Windows Phone 8.

iPhone 6 rumored to run 2K Retina screen

According to head Asian cites “Apple employees” an anonymous source, the next iPhone 6 could boast a display well above what was expected until today with the resolution Quad HD 2,560 x 1,440 pixels , a possibility that would mark a truly significant increase from the current 1,136 x 640 Retina current.

This article does not mention what will be the model of the iPhone 6 concerned (4.7 or 5.5 inches), or if it will be both, but until now has not been taken into account this possibility.While in March, the well-known insider Sonny Dickson spoke of a possible Retina Display Ultra 389 ppi compared to the current 326 ppi, Mark Gurman of 9to5Mac recently said that Apple could use the technique to provide tripling pixel resolution 1,704 x 960 as mentioned just above.

It would make sense that choice? Considering the evolution of the Apple display seems too a big jump.

Two new images of iPhone 6, 4.7 and 5.5 inches

A couple of new photos of both models of iPhone 6 have been published on Twitter by “SonnyDickson” , portraying them side by side. The second image shows clearly that there are two models, but gives a good idea of the size difference between the smartphone version.

All other details are the same as those of which we have spoken several times, rounded edges and form factor diverse than the current iPhone 5S and 5C. Below the image of the two with focus on rear bodywork.
