SpaceX missiles break the sound wall, landing on the ground

Falcon 9 missiles returned to Earth after bringing Dragon ships carrying tons of cargo to the International Space Station (ISS), on July 25.

"Falcon missiles return from space with two supersonic explosions , " wrote Elon Musk, SpaceX's CEO, when posting videos on social networks. In the video, the first floor of the Falcon 9 double-deck missile breaks down the sound wall, creating two supersonic explosions caused by shockwave in both the head and tail.

This is the second landing of this missile floor.

This is the second landing of this missile floor. It was used in the launch of a cargo ship for the ISS station in May. The Dragon train of the latest launch also operated three times. The ship used to go to the ISS station in April 2015 and December 2017.

Reuse is an important goal in Elon Musk's long-term plan. The billionaire wants to cut costs of making space flights, turning Mars colonization and other ambitions economically feasible. Blue Origin, a company founded by Jeff Bezos, also aims to achieve the same goal.

Dragon ship approached the ISS station on July 27, carrying 2.3 tons of cargo. About half of them are scientific devices, helping astronauts perform dozens of experiments. The ship will be connected to the ISS station for about a month, then return to Earth and land on the Pacific Ocean.
