The Kennedy Space Center launch team was assessing a potential hydrogen leak in the tail service mast umbilical, located at the base of the Space Launch System (SLS) core stage.
The launch weather outlook was 80% favorable as NASA began the nearly 4 hr. process of loading the SLS core stage with 196,000 gallons of liquid oxygen and 537,000 gal. of liquid hydrogen.
After more than 30 countdown simulations, two core-stage Green Run static engine firings and four launchpad wet dress rehearsals, countdown clocks at Kennedy Space Center were scheduled to start ticking down on Aug. 27 for the long-awaited launch of the first Space Launch System rocket.
T-Mobile has announced an agreement to use SpaceX’s Starlink constellation of low-Earth-orbit communications satellites for text message coverage across the continental U.S., Hawaii, parts of Alaska, Puerto Rico and U.S. territorial waters—remote regions outside the signal of T-Mobile’s terrestrial network.
