In 2002, together with the Pirates theme, BRIO started a Space line. Bit of a strange connection maybe, space and trains. There's nothing in space, so unless they were thinking of starting a complete fantasy world they would be out of ideas pretty fast. Turns out they were because only four items saw the light of day and 2003 was the last year for the Space theme. The Space Shuttle program's retirement was announced in 2004, so that lines up.
