Green Launch (USA) offers an environmentally friendly and cost-effective alternative to traditional rocket launches – a launcher powered by hydrogen fuel. This publication reports NewAtlas.
The launcher is a long tube filled with hydrogen with the addition of helium and oxygen. Gases serve as an alternative to gunpowder or other pyrotechnic charges, accelerating the payload to tremendous speeds.
The company has already built a 16.5 m high test facility and tested it at a site in Arizona at the end of 2021, achieving speeds of more than Mach 3 and sending a projectile into the stratosphere. This year, the company intends to provide the object with a speed sufficient to overcome the so-called. “Karman Lines” – a height of 100 km, on which the border with space lies.
Launches can be carried out in this way every 60-90 minutes, while, as the company assures, the cost will be regarding 10 times less than when delivering cargo on a rocket. “Your satellites and payloads can be in orbit in 10 minutes,” says Eric Robinson, director of business development at Green Launch.
Among the partners and clients of the company are the University of California at San Diego and Harvard, the sponsor is the US National Science Foundation.
In addition to reducing costs, Green Launch representatives emphasize the environmental friendliness of the project – the lack of a first stage in rockets will protect nature from harmful effects, since the combustion of hydrogen in the cannon itself leaves no emissions other than water. And operators of constellations of satellites will be able to launch them one at a time, which will avoid the risk of losing a large number of satellites in the event of an unsuccessful rocket launch.
