That unnamed multinational mission would apparently start preparations by 2025 -- take note that Japan doesn't have a guaranteed seat yet, but it's hoping to get one by contributing to the project. JAXA will reveal more details about its space exploration dreams at Japan's International Space Exploration Forum in March 2018. We're guessing it has other big missions on the docket, seeing as China and India are already making waves in what's dubbed as the "Asian space race."

In addition to sending an astronaut to our planet's natural satellite by 2036, China also intends to explore the dark side of the moon in 2018. India successfully tested its first reusable space shuttle in 2016 and set a record for launching 104 satellites aboard a single rocket earlier this year.
