The founder of SpaceX and Tesla, Elon Musk, commented on an article by Roskosmos CEO Dmitry Rogozin about the launch of Crew Dragon on Twitter.
In the comments under the tweet of journalist Eric Berger, who cited the English translation of Rogozin’s material, the entrepreneur wrote: “This is something!”
According to Musk, the successful Soviet development of the 80s on oxygen-hydrogen engines pushed him to create a Raptor oxygen-methane engine. The businessman noted that this engine has a greater momentum than oxygen-hydrogen.
Earlier, Rogozin in his article in Forbes magazine complained of ridicule from the United States after the launch of the Crew Dragon spacecraft to the International Space Station (ISS). According to him, after a successful test of the ship in Washington, they began to shower him with jokes and ridicule, although “it would be appropriate to thank our Soyuz, its Soviet developers and Russian engineers, who in recent years have continued to modernize this most reliable manned ship in the world.”
On May 30, at 10:22 p.m., the Falcon 9 rocket with the Crew Dragon manned spacecraft launched from the 39th launch complex of the John Fitzgerald Kennedy Space Center in Florida. The launch to the ISS was the second for Crew Dragon and the first passing with the crew on board. The docking of Crew Dragon and the ISS should take place approximately 19 hours after the launch.
Since 2011, people on the ISS have been delivered exclusively by Russian manned spacecraft of the Soyuz series. The corresponding contract between NASA and Roscosmos, involving the delivery of one astronaut to the ISS for $ 90 million, ends in October 2020.
