Two by Two - S1-E6
Continuity mistake: When Alicia presents the slingshot trajectory, Eva says the solar sails will provide "more than enough" power to reach the planet with the U238. Shortly after the sails are deployed, the edge of one of them is damaged, causing the ship to lose enough power to start dropping back to the star. But you can see that about 1/10 of one of the six sails is damaged, or 1.7% of the entire sail array. How is "more than enough" reduced to "not enough" when they lose such a small part of the sails?

Factual error: They are headed to Proxima, the closest star to Earth, but somehow use another system, a binary star, to use solar sail propulsion to get to a planet to get uranium-238. There is no closer star.

Factual error: The ship is using solar sails to accelerate. The sails are far too small to make a significant change to the speed of the ark. Also, when they approach breakaway, the ship rumbles. There is no mechanism for a transient stress. It is not like breaking the sound barrier.
