An engine issue during final liftoff preparations postponed the launch of NASA's mighty new moon rocket Monday morning on its test flight. No astronauts were inside the rocket's Orion capsule. Instead, three test dummies, fitted with sensors to measure vibration, cosmic radiation and other conditions, were strapped in for the six-week mission, scheduled to end with the capsule's splashdown in the Pacific in October. Assuming a rescheduled flight of NASA's 21st-century moon-exploration program, named Artemis after Apollo's mythological twin sister, goes well, it would pave the way for a crewed flight around the moon and back as soon as 2024. A two-person lunar landing could follow by the end of 2025. Prior to the postponement of today's launch, KAN reporter Naomi Segal heard more about the Artemis mission, and the Israeli role in it, from Ettay Nevo, editor and space writer on the Davidson Institute of Science's web site.
