praised the story's use of two prominent science fiction themes—changing the future, and discovering one's own death and attempting to alter it—comparing it favourably to The Twilight Zone, though he felt that it was diminished by the trope of planetary revolution as previously told in The Daleks and The Web Planet. In 2009, Mark Braxton of Radio Times felt that the story "kicks off so well", but failed to take the opportunity to discuss ideas such as predestination; he praised Vicki's "vibrant" character, and described the scene of the Doctor in a Dalek casing as "one of the few elements that make this rather tedious traipse memorable". In 2010, Total Sci-Fi Onlines Jonathan Wilkins similarly enjoyed the first episode, but described the remaining three as "dull, bog-standard Who" that "plods rather than races towards a deeply unsatisfactory climax". SFXs Nick Setchfield enjoyed the "lovely fourth-dimensional weirdness" of the first episode and the "refreshing" Moroks reminiscent of Douglas Adams's work, but ultimately criticised the serial for being a dull representation on the show's formulaic "rebels vs despots" storyline. Writing for Doctor Who Magazine, Graham Kibble-White said that the first episode falsely set the audience up for "three more weeks of high-concept plotting", which ultimately became "dreary" except for some of Hartnell's charm. Cliff Chapman of Den of Geek considered the first episode "slow and never really paid-off" and criticised the performances of the guest stars, but lauded the camera direction, effects work, and main cast. DVD Talks John Sinnott praised the mysterious storyline and comedic moments. Charlie Jane Anders of io9 listed the first episode's cliffhanger as among the programme's best. In 2021, Catriona Mills identified the Space Museum as an inverse of British museums: while the former displays conquests on a colonised planet, the latter displays colonial treasures in the heart of an empire. Commercial releases A novelisation of this serial, written by Glyn Jones, was published by Target Books and W. H. Allen & Co. in 1987. Jones altered the story's structure and restored the humour removed by Spooner. BBC Audiobooks released a double-CD soundtrack of the serial in May 2009, with narration by Maureen O'Brien; the set also included an interview with O'Brien. It was later included in AudioGO's Doctor Who: The TV Episodes: Collection 6 in September 2013, alongside the original camera scripts. Selected stock music from the serial was included in Space Adventures, a cassette soundtrack
