NASA's crucial fuelingArtemi moon rocket

Today (September 21), NASA will undertake a critical fuelling test of its Artemis 1 moon rocket, which you can watch live.

Technicians are set to begin loading supercold liquid hydrogen and liquid oxygen propellants into Artemis 1's propulsion system. [{ "selector": ".xxfwe-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateX(-104.4912280701754px)", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }, { "selector": ".efdkl-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(calc(600px - 525px))", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }]

[{ "selector": ".ojgtt-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateX(-104.4912280701754px)", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }, { "selector": ".papmb-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(calc(600px - 515px))", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }]

The SLS will be used by Artemis 1 to propel an unmanned Orion capsule to and from lunar orbit. [{ "selector": ".fkqbe-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateX(-104.4912280701754px)", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }, { "selector": ".fdlur-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(calc(600px - 515px))", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }]

The test flight was meant to take off late last month, but it was delayed twice due to technical difficulties. [{ "selector": ".mrtmu-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateX(-104.4912280701754px)", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }, { "selector": ".dpxak-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(calc(600px - 515px))", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }]

The second was a liquid hydrogen leak that happened in the days leading up to a planned liftoff on September 3. [{ "selector": ".jnajp-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateX(-104.4912280701754px)", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }, { "selector": ".eaemd-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(calc(600px - 515px))", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }]

The Artemis 1 team repaired two seals around the leak, as well as a "quick disconnect" connecting the SLS core stage. [{ "selector": ".splkj-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateX(-104.4912280701754px)", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }, { "selector": ".nfrau-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(calc(600px - 515px))", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }]
