Scooby-Doo! Where On Mars Are You?
According to Fred, Max "runs" the National Space Agency, so Mystery Inc. paid him a visit after seeing aliens loading crates onto a spacecraft in the woods. He informed the gang about several alien sightings and the disappearance of a Russian space station and its crew before inviting them to watch the launch of a rescue shuttle headed to Mars, from his office. He doesn't seem to get upset when Shaggy and Scooby are accidentally launched to Mars instead of the astronauts, and congratulates Shaggy personally once the aliens are captured.
