Nick Frost plays the character of Space Commander Michael "Mike" "Lucky Jack" "Hendo" Henderson. According to the official website of the series, Henderson's "Space Force File" describes Henderson's career arc this way: "Henderson rose through the ranks in exactly the way we say people can in the recruitment ads, yet endeavour to prevent in practice. Henderson shows initiative; always a dangerous sign." It also says Henderson's education was received at
Dagenham Secondary Modern and New
Portsmouth Cadet Camp. The website further describes Henderson as an
idealistic explorer, eager to meet new races, and feels he is undervalued given his low-priority assignments. Frost's character also has a recurring theme, his favourite show,
Captain Helix. He is very protective of his Commander's chair, which he refers to as "
Spinning Jenny." •
Kevin Eldon as First Officer Eduardo Pauline York – a brilliant scientist and tactician, second in command of the
Camden Lock. He is also a borderline
sociopath, obsessed with and taking immense joy in violence, needing only the slightest provocation to attack someone. He believes in a hardline
doctrine and feels Commander Henderson is too lenient regarding the crew and application of regulations. He does not trust Technical Officer Jeffers, and has the ability to hold his breath for seven and a half hours to avoid the effects of sedative gas. He also shows great affection towards Sandstrom, appearing to be in love with her at certain points in the show, even becoming jealous when Vine is kissing Sandstrom in his "Pub-conscious". Like his friend Henderson, York also watches
Captain Helix. At times, he can be quite poetic when describing acts of violence. •
Miranda Hart as Diplomatic Officer Chloe Alice Teal. Teal has an obvious crush on Commander Henderson, who has not responded to her advances. Teal's skills as a diplomat could be questioned, as during the episode
Hello, Queppu, her drunken outburst results in the Queppu imprisoning the three senior officers of the
Camden Lock. She failed her final exam to become an officer, and is only present on the
Camden Lock as her father is an ambassador. In series two it is revealed that Teal is a devout agnostic, a belief which has apparently become a more formal religion in the future. She is also the
yoga instructor on the ship. •
Stephen Evans as Navigator Dave Vine. Vine's greatest apparent achievement to date is purchasing a planet in an auction. The planet was quickly renamed Vineworld with such locations as Vine City 1 and Vine Ridge. Vine is a quiet member of the crew, uncomfortable with standing up to the outgoing personality of Jeffers or the
authoritarianism of York. He is a collector of 1990s "antiques", believing it to be a simpler time; this is reflected by his "pub-conscious", which is the only dream he has, a pub in 1995, where it is revealed that he, like York, is attracted to Sandstrom. •
Dan Antopolski as Technical Officer Karl Jeffers, an easy-going and lax member of the bridge crew who has been placed in command of the
Camden Lock on at least two occasions by Commander Henderson. He dislikes York and makes written notes on all the senior officer's mistakes. Jeffers has a liking for alien music; in particular, he enjoyed listening to the Lallakiss war anthem,
"Kill the Humans", whilst on duty. •
Petra Massey as Sandstrom – an "enhanced human", a cyborg interface needed to ensure the
Camden Lock keeps functioning. She agreed to have her body and mind modified in exchange for the Space Force paying off her
student loan, assuming the offer would not be made if the procedure was not safe. Her personality was then overwritten and she functions much like an
android, although chocolate seems to have an adverse emotional effect on her, leading to
hypersexuality. She seems to have a lot of affection for York, and is much more obvious about her feelings for him than he is about his for her. She gets very jealous whenever another Enhanced comes on board. She appears to interact with the ship via deliberate dance-like movements, and rubbing or stroking the luminescent tubes that surround her usual working space. •
Maggie Service as a variety of Computer Voices. These serve primarily as throwaway lines and interstitials, and include user interfaces (
To access the toilet, enter the second, fourth and eighty-third numbers in your security code) and shipwide announcements (''Attention all crew: Today is Take Your Clone to Work Day. If you don't have a clone, go and see the Clone Officer on Level 7''). In series two, other computer voices are played by Ewan Bailey. •
Waen Shepherd as Gareth Stannis, the actor who plays the title part in the television drama
Captain Helix, watched obsessively by Captain Henderson in the privacy of his cabin as a source of emotional comfort. Captain Helix – who resembles a somewhat
camper version of
Doctor Who – may also not be quite what he seems. ==HMS
