In 1970, a Zambia-based nun named Sister Mary Jucunda wrote to Dr. Ernst Stuhlinger, then-associate director of science at NASA’s Marshall Space Flight Center, in response to his ongoing research into a piloted mission to Mars. Specifically, she asked how he could suggest spending billions of dollars on such a project at a time when so many children were starving on Earth.

Stuhlinger soon sent the following letter of explanation to Sister Jucunda, along with a copy of “Earthrise,” the iconic photograph of Earth taken in 1968 by astronaut William Anders, from the Moon (also embedded in the transcript).
