Prime Minister Justin Trudeau has announced that Canada will partner with NASA to build a portion of the Lunar Gateway, returning humans to the moon by 2022. 

"Canada will be going to the moon," he said during the announcement. 

The project, spearheaded by NASA, is a space station that will be sent into orbit around Earth's moon, allowing astronauts and scientists to travel to and from the moon regularly.

The Lunar Gateway is the next step in a long-running process of getting Earthlings to Mars, NASA says. It will have a living space, docking stations, and research labs.
