*Valerian and the City of a Thousand Planets* starts with this awesome montage

showing humanity's progress through a series of peaceful handshakes as vessels and space stations rendezvous and their crews meet and shake hands.

The initial footage is from the [1975 Apollo-Soyuz Test Project](https://en.wikipedia.org/wiki/Apollo%E2%80%93Soyuz_Test_Project) and then proceeds through sequences in 2020, 2031, and 2150 with various Earth and Galactic cultures meeting in peace.

Now, my question is about the dates selected.   This montage is clearly crafted to draw the viewer into the setting and make it appear connected to our present day rather than some arbitrary distant future or place (cf. *Star Trek* and *Star Wars*).   Yet the station depicted in **2020** is clearly far beyond what we'll have in the immediate future, so the connection is broken (for me). 

So, do we have any commentary on this choice?   Does the date have a significance in the comics?  Is it *not* supposed to be our future?   Is there some other explanation?
