happy anniversary humanity

It was 50 years ago today that Yuri Gagarin changed the world. Humanity was no longer confined to one planet.

We haven't accomplished all that we've dreamed. But it is still amazing to me, that in half a century, we've walked on the Moon, probed many planets and moons, discovered thousands of planets in hundreds of solar systems, and reached into the very deepest depths of the Universe.

And, of course, it was 30 years ago that the NASA Space Shuttle programme began. Despite some hardships, it has been an incredible journey. Without the shuttles, we would not have built the International Space Station.

I find it difficult to imagine where we'll be another short 50 years from now.
