Murder on the Shuttle Sceptre

There was a murder on Shuttle Sceptre, and you are the detective hired to find the killer.

There are 4 Astronauts on board: Red, Blue, Yellow, and Green. One of them is responsible for the murder of the Orange Astronaut.

You are a master interrogator. Some even say that you seem to "run around in people's heads" to force the truth out of them. We will see if that's true.
