Does "ballistic descent mode" mean that the braking thrusters were inoperable, or just that the launch escape system was not in use?

- sathackr 8y agoIt means that the angle of descent of the capsule was much greater, so they encountered thicker atmosphere quicker than ideal, causing greater decelleration forces on the capsule than they would normally experience.
- Symmetry 8y agoA Soyuz only fires thrusters twice during descent. Once to go from orbit to re-entry and once immediately before impact to provide a gentler landing. During descent it normally generates a bit of lift from positioning a weight inside the crew capsule which makes the CoM off center which makes the descent not-quite-ballistic. I imagine the phrase refers to that not happening here.
