Ed Gold, an Australian born in 2008, was second in command at Bowie Base One. Captain Adelaide Brooke and he had an edgy relationship. On several occasions he tried to take heroic or commanding actions, only for her to order him back to his post.

Biography
Ed was fascinated by space travel. He became a US citizen in 2040, hoping to become a NASA astronaut, but returned to Australia in 2044 to campaign for a national space programme. He argued the country had the infrastructure, industry, and university base to achieve this. His campaign led to the construction of a space elevator off the coast of Western Australia.

In 2059, when the Flood attacked the base, Andy Stone, Maggie Cain, Tarak Ital, Steffi Ehrlich, Roman Groom and he were taken over. When the Tenth Doctor arrived at the base, Gold thought he was the culprit. He was proven wrong. When the severity of the infection became clear, he reminded Brooke of the evacuation protocols and was ordered to prep the base's shuttle.

While the shuttle was being readied, the infected Maggie Cain got in and infected him by shooting water up the shaft to the cockpit. To keep the infection from reaching Earth, he blew up the ship before he fully transformed. (TV: The Waters of Mars)
