According to the latest research, the pollution caused by SpaceX, blue origin and Virgin Galactic rockets may damage human health and the earth's climate Air pollution caused by rockets, published Tuesday in the journal physics of fluids, digitally simulates the exhaust gases emitted by standard rockets at different heights, similar to SpaceX's reusable rocket Falcon 9.
According to the study, the increase in rocket launches by commercial space companies such as Elon Musk's SpaceX, Jeff Bezos's blue origin and Richard Branson's virgin Galaxy "may have a significant cumulative impact on the climate" because each launch produces a large amount of carbon gas and nitrogen oxides.
According to the standards of the World Health Organization, the concentration of nitrogen oxides released by the rising rocket into the atmosphere of 2 cubic kilometers is considered "harmful to human health". The authors of the study added that as the number of commercial rocket flights increases, the consequent air pollution must be investigated.
Blue origin spokesman said that its "new Shepard" rocket "is fueled by efficient and clean liquid oxygen and liquid hydrogen", and the only by-product is "water vapor without carbon emission". At present, blue origin is planning its fifth manned flight in May. SpaceX plans to launch 60 Rockets this year.
