The nosecone of Stratos III will be recovered because all payloads and important flight data will be stored there. The motor and tank are discarded since it would increase the recovery system mass significantly. The recovery of Stratos III will happen after the rocket has reached apogee. After the apogee, the tank will separate from the nosecone. This separation will make the recovery of the rocket easier since the nosecone will go into a flat spin that will cause an increase in drag.
Because the nosecone will be spinning, a large parachute cannot be deployed, since it would entangle with the nosecone and therefore, it would not inflate. To stop the spin, a small drogue parachute will be deployed. This drogue parachute is made from Twaron, a light and strong para-aramid material. Furthermore, to ensure that the lines of the drogue do not entangle, a cold gas deployment device (CGDD) is used. This system will shoot the drogue at a velocity of 20 m/s.
At about 1000 meters, the main parachute will be deployed. This parachute will be pushed out by a spring system since the drogue ensures there are soft deployment conditions. Once the main parachute inflates, it will decelerate the nosecone to below 20 m/s for a safe water landing.
