NASA’s top human spaceflight official says the maiden flight of the Space Launch System, a behemoth booster designed to loft astronauts on expeditions into deep space, will be delayed from November 2018 until some time in 2019, according to a report published by a U.S. government watchdog Thursday.

Stephen Clark, Spaceflight Now’s editor, asked NASA’s acting administrator about the space agency’s commercial crew and Artemis programs during a one-on-one virtual interview Tuesday, April 20.

The three U.S. astronauts aboard the International Space Station said Monday they’re ready to sign up for a trip to the moon if NASA can meet the Trump administration’s newly stated goal of returning Americans to the lunar surface within the next five years.
