Just find your designated LEO and you'll be fine5/5

MetroiD · 2023-11-23 · value 5/5 · build 4/5

The ISS orbits our planet at an altitude of 400 klicks - which places it firmly in Low Earth Orbit (LEO). Space is still seemingly abundant there, if you'll forgive the crude pun - though in all fairness, the Station requires annual upkeep to the tune of a few millions (yes, six zeros) just to offset the significant damage that man-made space debris regularly causes. In our city flat though, space is very much at a p

Review for the ISS5/5

TheBrickDudeStudios · 2020-07-07 · value 4/5 · build 4/5

This is a lego ideas set. This set comes with the International Space Station, A space shuttle, Some other satellites, 2 astronauts and a stand for the space station. This set has tons of details and I like that it does. The Solar panels are all prints, and I am glad that they are because if they were stickers that would be a nightmare for me and a lot of other people. This set is a lot bigger than I thought it would

REGINALDO · 2020-04-22 · value 5/5 · build 5/5

The 21321 International Space Station set is a classic from Lego. Truly magnificent, a relic for Lego worshipers and fans, and of course a set that depicts the International Space Station. And mainly, for fans of space, I mean, space stations, spaceships, among other space universe, set 21131 was excellent. For me it was very emotional when I bought it, I got a glimpse, even at the age of 47, as a Lego fan, I say tha

In 2003, I got several sets from the short-lived Lego Discovery theme. Branded for the Discovery Channel, all these sets focused on space exploration. One of them, was 7467-1 International Space Station , Lego's first attempt at capturing the International Space Station. I got it as a kid, and built it along with the Mars set focused on Spirit and Curiosity. The 2003 space station set... was terrible. It was a gangly
