Translunar Coast Hat

Following the Translunar Injection (TLI) burn, Artemis II enters its coast phase—an unpowered stretch of flight where the spacecraft travels toward the Moon on a precisely planned path. With the engines off, everything is driven by orbital mechanics: the velocity from TLI, Earth’s decreasing pull, and the Moon’s growing influence. It’s a controlled free-fall through cislunar space; quiet, efficient, and essential to the mission.
