Pats on the back, perhaps

Usage examples of burps.

These thruster burps were similar-first a double firing to stabilize the ship during a roll so the command pod was facing away from the planet normal during rotisserie mode to spread the solar heating uniformly along the ship's surface without using field coolant-but only eight minutes here-and here!

Then the final paired burps, which might accompany the larger thruster firings that would roll the ship back with the command-pod cameras aimed down at the planet.

If the star gave off with one of its burps before they reached Shadrach, the ship was most likely gone.
