We all know that space doesn't have air , hence it has no friction. then when rocket reaches space , traveling from earth,after launching its satellite ,1) Where will the rocket go?2) What will happen to rocket?3) How do spaceships land on moon,since they cant put brake when there is no friction?4) How can we control the velocity of rocket as well as the satellite?

hi

Even though space doesnot have friction . newtons third law will work without fail. You have a propeller to propel the rocket in opposite direction of its movement to slow it down.

This will work irrespective of presence of gravity or friction .
