Question

In 1986, several robotic spacecrafts were sent into space to study the Halley's Comet. Which of these statements best explains why humans should continue to send robotic spacecrafts into space?

a. They absorb harmful radiations in space.
b. They help change weather conditions on Earth.
c. They help discard some myths about objects in space.
d. They destroy meteors and comets which might strike Earth.

Answer 1

c. They help discard some myths about objects in space.

When we learn something new, then we know more stuff,
and that helps us avoid ignorance and superstition.

The REAL question is:
Why should we continue to send robotic spacecrafts,
and NOT spacecrafts piloted by people ?
