Project Proxima is a hypothetical, light-speed space mission to the Proxima Centauri star system. The aim is to create a teaching tool that helps explain the vastness of interstellar space (it's big).
Today Proxima has traveled nearly 19 trillion km - that's about 47% of the today distance.
A lot has happened in the time since launch: perhaps most notably are the rise of Trump and the British referendum on Brexit. Most interestingly, however, that since launching the Project Proxima mission, scientists have discovered an earth-like planet in orbit around the Proxima Centauri system.
You can get involved in the mission by following on Twitter, or tracking the progress on the website.
