What is "retropack"

Usage examples of "retropack".

The retropack wrapped around the edges of the heat shield and held the retro-rockets.

Once the rockets were fired, the retropack was supposed to be jettisoned.

This was an indirect way of asking for some explanation for the mystery of keeping the retropack on.

But if he was going to re-enter with the retropack on, then they wanted the straps in place for some reason.

If the heat shield was loose, then it might come off during the re-entry, unless the retropack straps held it in place long enough for the capsule to establish its angle of re-entry.

Part of the retropack must still be attached and the drag of it is trying to flip the capsule… He couldn't wait any longer.

Just a steady push at her back, a smooth hiss as the retropack burned.
