SAFER is worn like a backpack. It uses small jet thrusters to let an astronaut move around in space.

If the moon landing was real, they ask, why didn't the lander scatter dust when it touched down? In reality, the lander was traveling horizontally much of the time and the thrusters that controlled its landing were not pointed down. Radiation from the sun also made the dust highly charged and it clung to the moon’s surface.

Engineers and ground controllers will conduct the first of three mid-course correction burns about 12 hours and 30 minutes after launch, firing Webb’s thrusters to maneuver the spacecraft on an optimal trajectory toward its destination in orbit about 1 million miles from Earth.
