Neil Armstrong and Buzz Aldrin were the first humans to walk on the Moon, but it was robots who
paved the way. Take a journey through decades of triumph - and frustration - and scientists and
engineers found ways to extend humanity's vision beyond Earth. Come back often. This story is far
from over and we'll be adding history as it happens.

solar system and back here on Earth. We've included launches, mission events, anniversaries, celestial
events and even a few birthdays. There's never a dull moment in space.
