With a radius of less than ten meters, any perceptible spin will only serve to make the crew sick. That’s not to say that there aren’t reasons why you might want a slight spin in an interplanetary flight, but based on past experience, we can be fairly sure Musk doesn’t understand those reasons.

Elon Musk is a terrible engineer (and why that is important)

In a tweet on Friday, Musk posted a GIF of Dr. David Bowman, the main character in 2001: A Space Odyssey running around a track in space. He said in the tweet that the BF Spaceship will feature a similar track and that running around on it “will look something like this.”

During the scene in the film, Bowman is running around a centrifugal device that creates enough gravitational force to allow him to run and get exercise. But when Bowman was running around in space, he was on the Discovery One spaceship and not the BF that SpaceX is working on.

First, a very brief and hopefully painless physics lesson (with apologies for any details I might screw up – – it’s been a long time since I took a class in the subject). We are all familiar with the idea of centrifugal force. When traveling in a circle, the amount (Read more…)
