Teams with NASA and Boeing, the core stage lead contractor, at NASA’s Michoud Assembly Facility in New Orleans have fully integrated all five major structures of the Space Launch System (SLS) rocket’s core stage for Artemis II, the first Artemis mission that will send four astronauts around the Moon and return them home. Technicians joined the engine section to the rest of the rocket stage March 17. Next, teams will integrate the four RS-25 engines to the engine section to complete the stage. Located at the bottom of the 212-foot-tall core stage, the engine section is the most complex and intricate part of the rocket stage, helping to power Artemis missions to the Moon. In addition to its miles of cabling and hundreds of sensors, the engine section is a crucial attachment point for the RS-25 engines and two solid rocket boosters that produce a combined 8.8 million pounds of thrust at liftoff. It houses the engines and includes vital systems for mounting, controlling, and delivering fuel from the propellant tanks to the engines. Image credit: NASA/Eric Bordelon

The recommended targets are real, but the largest health gain is between doing nothing and doing a little. That is the part worth knowing if you are starting from nothing.

Sleep is not one state but a cycle through several, each doing different work. Most sleep disorders are a failure to complete that cycle rather than a shortage of hours.
