NASA is aiming to put Americans back on the Moon before China’s first crewed landing 🌕🇺🇸
• Artemis IV is targeting a 2028 landing, while China aims to land astronauts by 2030
• It would mark humanity’s first return to the lunar surface since 1972
• With support from President Trump, Jared Isaacman is challenging NASA’s team to bring Apollo-level intensity, discipline, and engineering ownership to the mission
• NASA wants the mission to inspire a new generation of astronauts and engineers, just as Apollo did
“Apollo should never represent the upper limit of what NASA can achieve. It should be a standard we continuously strive to exceed”
