Description: Earned by participating in the 2017 Cosmonautics Day event (Russia region exclusive). This icon was also made available for purchase in all regions for a limited time during 2017.
* Legacy Icons: Legacy Icons don't act the same as legacy
skins.
It seems like some icons that are marked as legacy are still obtainable or the other way
around
where some icons that are not marked as legacy are not obtainable anymore.
