Elon Musk Unveils SpaceX Raptor Engine Test for Interplanetary Transport

SpaceX has successfully test-fired a new Raptor rocket engine that will launch a company’s designed interplanetary spaceship, according to a array of tweets from a company’s CEO, Elon Musk. The engine is being grown to help propel a absolute reusable rocket to Mars and over as partial of SpaceX’s Interplanetary Transport System.

Although Musk suggested some technical sum about a engine on Twitter, he betrothed to exhibit some-more tomorrow (Sept. 27) during his scheduled speak during a International Astronautical Congress eventuality in Guadalajara, Mexico. Musk did not divulge when a exam had taken place.

Earlier this month, Musk took to Twitter to announce a name change for a desirous Mars Colonial Transporter, that can go “well over Mars,” he pronounced in a array of tweets. The Raptor forms a critical partial of a newly named Interplanetary Transport System.

Through Twitter, Musk reliable that a engine’s projection is about 14 feet (4.3 meters) in diameter, and that a final chronicle will beget 3 million newtons of force, with a cover vigour 3 times that of a Merlin engines that now propel SpaceX’s Falcon 9 rocket.

“Production Raptor idea is specific incentive of 382 seconds and bearing of 3 MN (~310 metric tons) during 300 bar,” he wrote on Twitter. “382s is with a 150 area ratio opening (or Mars ambient pressure) nozzle. Will go over specs for both versions on Tues.,” he simplified in another tweet

Back in 2012, Musk described a Raptor engine as operative likewise to a engines that propelled NASA’s space shuttles, with a two-stage cycle that is some-more fit than a stream Merlin engines used by a company’s Falcon 9 rocket. Rather than regulating glass oxygen and kerosene as fuel as a Falcon 9’s engines do, Raptor will use glass oxygen and methane to revoke appetite costs as well, Musk pronounced during a time.

SpaceX intends to launch an uncrewed Mars goal in 2018, regulating a Dragon space plug and a Falcon Heavy rocket. The Interplanetary Transport System could launch humans to Mars as early as 2024 if all goes well, Musk has said.
