It can be used to target a bases on the Mars and land directly without an orbit insertion. The program will also allow to establish an orbit right over a specific base on a planet so that it is possible to continue the descent on the base. That's very useful when landing on the Moon. |

The program will compute the time to launch window and required launch heading. This program is the only one that doesn't compute any burn guidance data. A vessel specific ascent profile should be used to reach low orbit. |
* '''Orbit Eject''' program is required when starting interplanetary missions from the orbit. This program is used in a combination with the other programs to convert the Escape information into burn guidance data. | * '''Orbit Eject''' program is required when starting interplanetary missions from the orbit.
