Other mistake: Right at the start, as they're crashing, the computer narrates their rapidly-dropping altitude in feet. But the "altitude" dial we're shown is in metres. Most noticeable as they cross the 3,000 mark, when the computer voice and the height say/show the same number at the same time, despite the different units. 3,000m would be more like 9,000 feet, or 3,000 feet would be more like 1,000m.

Other mistake: One of the episodes shows John at a Marine base camp. It shows him wearing Army fatigues, and in Episode 7, Maureen jokingly says "weren't you a Navy SEAL?" right after he fails to throw this hook to get to safety from a tar pit. So what is he? A soldier? Marine? SEAL? Can't be all three.
Plot hole: At the end, when Maureen is searching for John in orbit, she only radios him after Will sees him clinging to the floating wreckage. Before that, she only used sensors aboard Jupiter to try and locate him. She makes no attempt at radio contact for any survivors, which would have quickened the rescue. John can also radio her back, but he did not attempt to call for help.raywest
Factual error: At the start the Robinsons are playing a game of fish, in weightless or free fall conditions. At about 1:30 the computer announces "Completing De-Orbit Burn." De-Orbit Burn involves deceleration. This is not free fall, they should be experiencing the deceleration and hence a sense of gravity. The cards should not float. (00:01:30)
