Japan Successfully Tests Possible Deep-Space Rocket Technology

Futurism reports:Japan's space agency JAXA has announced that is has successfully demonstrated the operation of a "rotary detonation engine" in space, a world's first. Such an engine uses a series of controlled explosions that travel around a circular channel at its base. The result is a massive amount of thrust coming from a much smaller engine using significantly less fuel — a potential game changer for deep space exploration, according to JAXA. It's a lucrative endeavor and Japan isn't the only country pursuing the idea. Researchers across the U.S. are testing out the technology to make rockets both lighter and more environmentally friendly... "We will aim to put the technology into practical use in about five years,"Jiro Kasahara, a Nagoya University professor who is working on the technology with JAXA, told the Japan Times last month. Ars Technica reports that detonation engines should theoretically weigh less than traditional rocket engines &mdash and that JAXA "plans to use data from this test for potential development of detonation engines for kick stages as well as first- and second-stage rocket engines." Futurism adds that in the same flight JAXA also successfully tested a second "pulse detonation engine."
