Two by Two - S1-E6

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.

Two by Two - S1-E6

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.

Get Out and Push - S1-E3

Factual error: Alicia realizes that the asteroid is actually a comet by its tail. However, earlier in the episode we are told we are far from any star (so no point in opening the solar sails). The thing is, comets only develop a tail when they are near a star, which blows gases off the comet with the solar wind (the same wind that could operate solar sails). So in reality, there would be no tail to this comet.
