What phrase describes the complex process of atmospheric entry, descent, and landing (EDL) for Mars missions?
Answer
The "seven minutes of terror".
The process required for landing robotic explorers on the surface of Mars involves atmospheric entry, followed by descent and a final landing sequence, collectively known as EDL. This maneuver is notoriously complex and technologically challenging due to the requirement for autonomous operation over millions of miles and the necessity for immediate, irreversible decision-making within a strict time frame. The inherent risk involved in successfully navigating the Martian atmosphere to reach the surface safely has given this critical phase the dramatic designation of the "seven minutes of terror".
