There is a fair chance of a partial recovery. Most partial recovery situations let us choose from among the following outcomes. Which brings us closest our mission?
The rocket lands hard, but not ballistic. Little or nothing is reflyable. We lose most or all of the data.
The mission package lands softly. Most or all of the mission package is reflyable. We recover most or all of the data. However, the motor section lands hard, but not ballistic. Little or nothing of the motor section is reflyable.
The motor section lands softly. Most or all of the motor section is reflyable. However, the mission package lands hard, but not ballistic. Little or nothing of the mission package is reflyable. We lose most or all of the data.
Details on Partial Recovery
Mach > 2. Ballistic. We fail to separate.
200-500 fps (guess).The rocket separates but the drogue is damaged.
120 fps. The rocket separates. The drogue deploys. The main does not deploy. Likely caused by the motor section riser wrapping around the drogue riser thus strangling the main bridle and inhibiting deployment.
Mission package @ 13 fps. Motor section @ 300-500 fps (guess). We disconnect the motor section from the riser confluence. The mission package lands under the main. The motor section crashes.
Mission package @ 300-500 fps (guess). Motor section @ 28 fps. We disconnect the mission package from the riser confluence. The motor section lands under the main. The mission package crashes.
One of the bodies lands under drogue, the other under a shredded main or no main. This would happen if the TD separation mechanism fails or the main contacts a body during secondary separation
32 fps. Total success. The rocket separates. The drogue deploys. The main deploys.
150-500 fps (guess). The main deployment force shreds the main or snaps the main riser. We could lose the drogue too.
The main deployment force exceeds the design limit for the main parachute system, but we have selected the motor section riser to be 20% weaker than the design limit for the main parachute system. The motor section riser breaks which reduces the mass of the system and thus the deployment force. We recover the mission package by the motor section lands hard.
