Why is it so hard to get humans back on the moon?
All about the money.
[The current programme] Artemis is expensive, but Apollo was exorbitant: the program cost around $290 billion in today’s dollars, according to the Planetary Society, compared with Artemis’s $93 billion. In those years NASA was often blessed with 4 percent of the nation’s budget. Today it’s lucky to get around 1 percent, with the additional burden of many other spacecraft, telescopes and research projects beyond human spaceflight to fund.
