This is one of those links I remember and reread every few years. I was surprised I hadn't posted it here before.

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
above photograph of Earth taken in 1968 by astronaut William Anders,
from the Moon. His thoughtful reply was later published by NASA, and
titled, “Why Explore Space?”
The distribution of the food to the needy is a completely different
problem. The question is not so much one of shipping volume, it is one
of international cooperation. The ruler of a small nation may feel very
uneasy about the prospect of having large quantities of food shipped
into his country by a large nation, simply because he fears that along
with the food there may also be an import of influence and foreign
power. Efficient relief from hunger, I am afraid, will not come before
the boundaries between nations have become less divisive than they are
today. I do not believe that space flight will accomplish this miracle
over night. However, the space program is certainly among the most
promising and powerful agents working in this direction.
Let me
only remind you of the recent near-tragedy of Apollo 13. When the time
of the crucial reentry of the astronauts approached, the Soviet Union
discontinued all Russian radio transmissions in the frequency bands used
by the Apollo Project in order to avoid any possible interference, and
Russian ships stationed themselves in the Pacific and the Atlantic
Oceans in case an emergency rescue would become necessary. Had the
astronaut capsule touched down near a Russian ship, the Russians would
undoubtedly have expended as much care and effort in their rescue as if
Russian cosmonauts had returned from a space trip. If Russian space
travelers should ever be in a similar emergency situation, Americans
would do the same without any doubt.
