What is an orbital insertion?
Quick Answer
An orbital insertion is the maneuver that slows a spacecraft enough to be captured by a planet’s gravity and enter orbit. Without it, a probe may just fly past.
The Full Story
Orbital insertion is a critical mission event in which a spacecraft fires its engines at exactly the right moment to reduce speed and enter a stable orbit around its target. The maneuver must be timed precisely because arriving too fast can cause the spacecraft to escape or crash. Mars orbit insertion, for example, is a tense operation for missions arriving at the Red Planet. Successful insertion allows spacecraft to begin mapping, communications relay, or detailed scientific observation.
