Editing Retrorocket (section)

===Landers===
Retrorockets are also used in landing spacecraft on other astronomical bodies, such as the [[Moon]] and [[Mars]], as well as enabling a spacecraft to enter an orbit around such a body, when otherwise it would scoot past and off into space again. As pointed out above (in connection with [[Project Apollo]]) the main rocket on a spacecraft can be re-oriented to serve as a retrorocket.  The Soyuz capsule uses small rockets for the last phase of landing.
