How It Works
Dual-phase recovery: single large main parachute decelerates from ~230 m/s to ~7 m/s, then six solid-propellant retro-rockets fire at ~1 m altitude to cushion the final impact to ~1.5 m/s for land-based recovery.

Details
The Soyuz descent module uses a combination of parachute deceleration and solid rocket braking for landing on the Kazakhstan steppe. A single main parachute of 1,000 square meters area deploys via a series of pilot and drogue chutes. Six solid retro-rockets fire at 1 meter altitude to cushion the final impact, reducing landing speed to approximately 5 km/h.
