A scathing report from NASA's Office of Inspector General (OIG) has highlighted several critical issues related to the development of the next version of the agency's Space Launch System megarocket, which will likely delay Artemis moon missions.

The report, released by NASA's internal watchdog on Aug. 8, focuses on the gigantic Space Launch System (SLS) Block 1B and its Exploration Upper Stage (EUS). Block 1B is designed to increase the amount of cargo SLS can carry to the moon. The upgraded version is key to NASA's long-term lunar plans and will be used for Artemis 4, currently scheduled to launch in 2028.
