NASA Conducts Fueling Rehearsal for Artemis II Lunar Mission

NASA conducted a fueling rehearsal for the Artemis II lunar mission's new-generation Space Launch System rocket on February 19. According to Jin10, the launch team at Florida's Kennedy Space Center loaded approximately 2.6 million liters of cryogenically stored propellant, including liquid hydrogen and liquid oxygen, into the 98-meter-tall rocket standing on the launch pad. The team simulated a launch countdown, halting the countdown 30 seconds before ignition without reporting any significant leaks. The clock was then reset to rehearse the final 10-minute procedure again. NASA announced the completion of the test late at night and plans to hold a briefing on February 20 at 11 a.m. local time (midnight on February 21, Beijing time) to discuss the next steps.
