Greg Martin

A third member of the Zero X crew was pictured in a photograph, alongside Captain Paul Travers and Navigator Brad Newman, which accompanied an article about the "jinx" which plagued the ship.

In an account dated to 2088, Newman, who was aboard the main body, reported that contact with the rest of the crew was lost six hours prior when the Martian Excursion Vehicle disappeared into a freak dust storm. After hearing the news, the controller of Kahra stated they did not have enough fuel to send out search parties and also noted the threat from the nearby Mysteron City. (PROSE: Zero X: Four Crew Missing) According to an account dated to 4 February 2067, with the abandonment procedure operative, Newman remained in sole control of Zero X as the captain and the other crew were still missing on the surface of Mars. It was noted that he would have to consider them deceased if radio contact had not resumed by the time the oribital schedule ran out. (PROSE: Stingray Storm!)

Behind the scenes
Although not named in Zero X: Four Crew Missing, the third crewmember is clearly Greg Martin. Like Travers and Newman, he debuted in the 1966 film Thunderbirds Are Go and subsequently became a main character of the TV Century 21 comic spin-off Zero X.
