The capsules can do a water splashdown with parachutes alone.

The capsules that land on land all seem to have some additional system to slow down in addition to the parachute. Boeing Starliner has airbags that deploy around and below the heat shield. Soyuz has a braking rocket system that fires immediately before impact.

Whoops! That’s my mistake.

“Nightfall”, by Arthur C. Clarke is a short story based on this premise.

Except in the story it’s a complex multiple-star solar system that makes it very rare for all suns to set at once.

Edit: It’s actually Isaac Asimov.

I highly recommend Python Control Systems Library, python-control on PyPi, as a replacement for the control systems toolbox.

Linux (at least the mainline version) never supported 16-bit processors. Linus started writing the operating system on his brand new 32-bit 386 machine, and he never looked back.

The proof is not that ancient. Pi was proven to be irrational in 1761, and proven to be transcendental in 1882.

For a long time the problem was known as “squaring the circle”: Given a circle in a plane, construct a square with the same area using a compass and straightedge. This was a famous unsolved problem in mathematics from antiquity all the way through the renaissance.
