NASA successfully pumped over 750,000 gallons of supercold propellants into its Space Launch System (SLS) rocket without detecting hydrogen leaks, marking a significant step towards the Artemis II mission, set for March 6. The practice countdown began on Tuesday, culminating in a simulated launch on Thursday where additional tests confirmed the team’s ability to handle unexpected issues. This mission will feature astronauts traveling farther from Earth than any before and is a precursor to the Artemis III lunar landing in 2028. After troubleshooting previous hydrogen leak issues, engineers resumed tests and achieved a safe fueling process for both stages of the rocket.
