NASA’s quiet supersonic X-plane has a new name

The move is part of the space agency's plan to help develop the X-59, a quieter technological vehicle being produced by Nasa's supersonic jet team.

Galveston is set to be the testing cite for NASA's supersonic prototype.

A sonic boom is the loud thunder-like sound that happens because of shock waves that are created when an object travelling through the atmosphere travels faster than the speed of sound.

NASA's experimental supersonic X-plane project has a new name: the X-59 QueSST. Virgin Galactic and Boom Technology are working together to build a supersonic jet capable of flying at twice the speed of sound - about 1,451 mph (2,335 km/h) - to cut the travel time from New York City to London down to 3 hours.

Town police chief Renato Mercado told AFP the shot was sacked from about 150 metres (490 feet) away. Later on, he said he was merely suspecting Halili's connection with drugs.

Lockheed Martin was to collaborate with NASA for this project and now, reports have emerged saying that by November, flight tests will be conducted over a populated region in Texas to test how silent the aircraft turned out to be. That's because new supersonic planes are being developed that can revolutionize commercial flights, and NASA wants to find out if the noise levels those supersonic aircraft put out will be off-putting to people on the ground.

An initial test of the research methodology using the F/A-18 was conducted in 2011 with the help of the USA military community that lives on base at Edwards Air Force Base in California. "But the airplane's shape is carefully tailored such that those shockwaves do not combine", said Ed Haering, an aerospace engineer at NASA Armstrong Flight Research Center. NASA intends to fly the X-59 over several towns or cities and gather data from residents on the ground about their perception of the sound the supersonic aircraft generates. They are being fronted with funds by Japan Airlines, who issued the company $10 million for their supersonic endeavor.

"Instead of getting a loud boom-boom, you're going to get at least two quiet thump-thump sounds, if you even hear them at all". Spike will be testing out its S-512 Supersonic Jet around the end of this year. This is why the F/A-18 is so important to us as a tool.
