Lunar Module Descent Engine

The Lunar Module Descent Engine was a specialized rocket engine designed for NASA's Apollo missions, used to gently lower the lunar module from orbit down to the Moon's surface. It provided controlled, precise thrust to navigate and slow the descent, ensuring a safe and accurate landing. Powered by hypergolic propellants (which ignite on contact), it could be throttled and shut off as needed during descent. This engine allowed astronauts to land accurately, avoid hazards, and prepare for lunar exploration, playing a critical role in the success of lunar landings.
