The universe is big, I mean really big, but our nearest neighbour is close by. Seeing our unique satellite orbit the Earth is as common an experience watching the weather. No need for a telescope.
The circumference of Earth (distance around Earth at the equator) is roughly 40,000 kilometres (25,000 miles). The distance to the Moon is 10 times the circumference of the Earth, or roughly 400,000 kilometres (250,000 miles). That sounds like a lot but compared with the dimensions of our solar system it’s nothing much.
The first humans walked on the Moon on 20th July 1969. I was 9-years old. I watched the event in our living room on a small black and white TV. Around the globe, hundreds of millions of people watched as Armstrong stepped out on the surface of the Moon for the first time. For good or ill, humanity changed on that day.
A plan for returning humans to the Moon is underway. NASA’s new lunar mission is ready for launch. Called “Artemis” a mission is on the launch pad. In ancient Greek mythology, Artemis was heavily identified with Selene, the Moon.
This project will work with industry and international partners, like the European Space Agency (ESA) to send astronauts to the surface of the Moon. The European Service Module (ESM) will provide for future astronauts’ basic needs, such as water, oxygen, nitrogen, temperature control, power, and propulsion.
It’s a big day. Exploration is a part of human DNA. These are the next steps. I wish the project every success.

 225,623 miles away when it’s at its closest. The Moon’s orbit is not a perfect circle. When the Moon is furthest, it’s 252,088 miles away.
