The first manned flight to the moon in half a century was scheduled to launch on Wednesday.
The mission, known as Artemis II, will send four astronauts aboard an Orion spacecraft to the moon for a 10-day flyby. Americans Reid Wiseman, Christina Koch, and Victor Glover, and Canadian Jeremy Hansen will crew the spacecraft.
The launch is scheduled for 6:24 p.m. ET at Florida's Kennedy Space Center.
