Beijing time on May 20 news, the latest research said,Pollution from SpaceX, Blue Origin, Virgin Galactic rockets could harm human health and Earth’s climate.
“Atmospheric pollution from rockets,” published Tuesday in the journal Physics of FluidsNumerical simulations of exhaust gases from standard rockets at different altitudeswhich is similar to SpaceX’s reusable Falcon 9 rocket.

Commercial space companies such as Elon Musk’s SpaceX, Jeff Bezos’ Blue Origin and Richard Branson’s Virgin Galactic, the study said an increase in the number of rocket launches,”Possibly significant cumulative impact on climate“,This is becauseEach launch produces a large amount of carbon gas and nitrogen oxides.
According to World Health Organization standards,Concentrations of nitrogen oxides released into 2 cubic kilometers of atmosphere by rising rockets deemed ‘harmful to human health’. The study’s authors added that as the number of commercial rocket flights increases, the accompanying air pollution must be investigated.
A Blue Origin spokesman said its New Shepard rockets are “fueled by highly efficient, clean liquid oxygen and liquid hydrogen” and that the only by-product is “carbon-free water vapor.” Currently, Blue Origin is planning its fifth crewed flight in May. SpaceX plans to launch 60 rockets this year.
