The turbulence from the increasing shock waves had created drifts of moon dust partially covering the Alpha buildings. In subsequent episodes, the dust is back in place.
Koenig only draws four of the solar system's planets but the computer immediately identifies it as Earth; there are more than likely thousands of planetary systems with at least four planets.
After Koenig's hit by an electrical discharge inside the cavern on the alien moon, Martin Landau is seen attempting to block the ruffled collar of his spacesuit from the camera's view, as it had been unintentionally damaged during the scene.
Quentin Pierre played a security guard throughout both seasons of the show and is seen in two places at the same time in this episode - donning a space suit as an Eagle One passenger while crouching down in an Alpha corridor wearing a hard hat.
