Moonfall

In 2011, astronaut Brian Harper works on a satellite on a Space Shuttle mission when a mysterious black swarm attacks the mission and kills a crewmate. Back on Earth, nobody believes his explanation, human error is blamed, and Harper is fired.

Ten years later, conspiracy theorist K.C. Houseman, who believes the Moon is an artificial megastructure, steals time on a telescope and discovers that the Moon's orbit is getting closer to Earth. He attempts to share his findings with Harper, who dismisses him, leading K.C. to go public on social media.
