[US Manned Lunar Orbit Mission Conducts Another Launch Drill] On February 19th local time, NASA conducted another rehearsal for fueling the Space Launch System (SLS), the next-generation lunar rocket for the Artemis 2 manned lunar orbit mission. At the Kennedy Space Center in Florida, the launch team loaded approximately 2.6 million liters of cryogenic propellant—liquid hydrogen and liquid oxygen—into the 98-meter-tall rocket on the launch pad. The team selected a simulated launch time, rehearsed the ignition countdown, and the countdown stopped as planned half a minute before ignition, with no apparent leaks reported. The clock was then reset, and the final 10 minutes of the procedure were rehearsed. NASA announced the test was complete late that night and plans to hold a briefing at 11:00 AM local time on February 20th (midnight on February 21st Beijing time) to announce subsequent steps.
