Fact check: Rocket propulsion functions in space because of universal physical laws, no air required - msnNOW

"There must be an external medium to have an opposite reaction - Propulsion in a vacuum is insanely absurd," it reads.  .

Propulsion occurs when an engine produces a force called "thrust," which pushes a rocket or fighter jet in the opposite direction. Though many jet engines do make use of air in their propulsion system, air is not necessary for propulsion.

Contrary to the claim made in the post, an "external medium" is not necessary for propulsion to occur, reports All About Space Magazine. .

This law states that "for every action there is an equal and opposite reaction," reads the primer. "In the case of rockets, the action is the force produced by the expulsion of gas, smoke, and flames from the nozzle end of a rocket engine.

The reaction force propels the rocket in the opposite direction." 

Based on our research, we rate FALSE the claim that propulsion can't work in a vacuum, so space travel isn't real
