Mafia 41. Rainie-1.

Here's that version.

"Welcome to Rainey-1" => "Welcome to Mars" => Nova (TV series) => Nova (TV series) => PBS channel => channel launch date

I started yawning somewhere in the middle. And there are no dates in the Russian Wikipedia article about the PBS channel. Tox, you're the mafia.

Check the connection with the movie "Independence Day". At least for fun. Because it has a very good tagline.

"Welcome to Earth!"
