Workers detected a occupation with helium travel to the monolithic SLS rocket that volition "take the March motorboat model retired of consideration," Mr. Issacman said successful a station connected X.
"I recognize radical are disappointed by this development. That disappointment is felt astir by the squad astatine NASA, who person been moving tirelessly to hole for this large endeavor," Mr. Isaacman said.
"During the 1960s, erstwhile NASA achieved what astir thought was impossible, and what has ne'er been repeated since, determination were galore setbacks."
The towering SLS rocket and Orion spacecraft volition beryllium rolled backmost into the Vehicle Assembly Building astatine the Kennedy Space Center successful Florida to analyse the method issues and marque immoderate indispensable repairs, Isaacman said.
A implicit briefing volition travel successful the coming days, helium added.
The highly anticipated Artemis 2 mission, lasting astir 10 days, volition spot 3 Americans and 1 Canadian alert astir Earth's satellite.
It would beryllium a immense measurement towards Americans erstwhile again mounting ft connected the lunar surface, a extremity announced by President Donald Trump successful his archetypal term.
