Original Dirty Pair: Flight 005 Conspiracy (1990)

In their latest case, WWWA tra-cons Kei and Yuri are dispatched to the Leo system to investigate two linked situations: the mysterious destruction of Space Shuttle Flight 005 (en route from Planet Zol to Planet Dolz) and the equally mysterious disappearance of a noted scientist. While quite routine at first, the investigation slowly turns sinister the farther Kei and Yuri go. Before long the Pair themselves have become targets, and the nasty attacks of their foes only further convince the duo how critical the case really is. Luckily for them, a mysterious stranger who lurks behind the scenes offers them warnings and evidence during crucial moments. Like it or not, Kei and Yuri have no choice but to solve the case if they wish to escape with their own lives.
