Knit Wit

Halfway to Mars, communications stopped working.
Commander Gregg had plenty of supplies, a library of movies and books, and all of the yarn he needed to keep his hands occupied.
At first, he thought he’d make a cap. Then, he knitted up a scarf.
The sweater was finished as the retrorockets fired, slowing down the lander’s descent to the Martian surface.
Gregg tried one last time to call Houston, but he’d forgotten about the communications delay.
Sixteen minutes later, Mission Control screamed in futility for Gregg to take off the cap and put on his helmet before cycling the airlock.
