NASA Administrator Jared Isaacman gave coffee a lunar endorsement Monday, joking that the beverage already belonged in the agency’s campaign to accelerate Artemis missions and build a sustained U.S. presence on the moon.
"Good. This was already part of the Artemis acceleration program," Isaacman wrote on X after new research highlighted potential health benefits from moderate coffee consumption.
The American Heart Association said in a scientific statement on Monday that up to 400 milligrams of caffeine daily, equal to five 8-ounce cups of coffee, is generally safe for most adults and may be associated with lower risks of heart failure, heart disease and stroke. The group stressed that the evidence shows associations, not proof that coffee causes better outcomes, and advised avoiding added sugar and saturated fat.
Isaacman, who flew the private Inspiration4 and Polaris Dawn missions before becoming NASA’s 15th administrator in December 2025, has pushed the agency toward faster, repeated lunar missions.
NASA’s next major step is Artemis III, a 2027 low-Earth-orbit flight that will test Orion rendezvous and docking with versions of SpaceX’s Starship and Blue Origin’s Blue Moon landers. NASA plans crewed lunar landing opportunities in 2028 as it works toward a permanent base near the lunar south pole.
The schedule still faces pressure. Blue Origin is repairing its launchpad after a May New Glenn test explosion, while both commercial landers have faced delays. Isaacman said Monday that Artemis III remains on schedule, though NASA has developed contingency options around its suppliers.
NASA has also awarded $590 million for additional robotic landers from Astrobotic, Firefly Aerospace and Intuitive Machines, expanding commercial missions that will scout and deliver equipment before astronauts arrive.
China adds urgency. Beijing plans to land astronauts on the moon by 2030 and develop an International Lunar Research Station with Russia by 2035. Isaacman has called the moon a "proving ground" for Mars and said NASA expects near-monthly missions in 2027 to begin building infrastructure.
