Orion's 11 Parachutes: A Soft Landing's Secret
11 Apr
Summary
- Orion uses 11 parachutes to slow from 25,000 mph for splashdown.
- A series of four parachute types ensure a safe 17 mph landing.
- Each parachute system has redundancy for a safe return.
The Orion spacecraft's safe return to Earth hinges on an intricate system of 11 parachutes. Designed to soften its ocean splashdown, these parachutes are crucial for decelerating the craft from speeds of up to 25,000 miles per hour. This process begins after the heat shield has reduced speed to 350 mph.
At 24,000 feet, the deployment sequence initiates, guiding Orion towards a controlled 17 mph impact in the Pacific Ocean. The system features four types of parachutes, starting with a Kevlar forward bay cover parachute. This is followed by two drogue parachutes for stabilization and deceleration, and then three pilot parachutes that deploy the main parachutes.
Each of the main parachutes boasts a massive 11,000 square feet surface area, constructed from lightweight yet strong nylon. Redundancy is a critical aspect, allowing for the potential failure of one parachute of each type while still ensuring a safe landing for the crew. Without this robust parachute system, a safe return would not be possible.
