The first manned flight of NASA's Orion spacecraft, which is being built to help humanity explore Mars and other distant destinations, may be delayed by two years, until 2023, agency officials announced today.
Orion's first crewed sojourn, known as Exploration Mission 2 (EM-2), is officially targeted for launch in August 2021. But after conducting a thorough review of the Orion program last month, NASA is now acknowledging the possibility of a delay for EM-2, saying the liftoff will occur "no later than April 2023."
