The April 2011 edition of Vogue Italia contained a four page article on Space: 1999. The article, "Moonbase Alpha Calling" by Jan Kollerstrom, appears on pages 120-123 of the supplement CASA VOGUE ("Vogue home", focusing on interior design). Pages 120-121 is a double page spread showing the Alphans on planet Piri; the text appears on one page only.
The article states that the series has a unique style with "steely minimalism of the 1970s" created with furniture and objects of Italian design. "The design is not a decorative element, but the protagonist itself." "The series is an authentic sample-book of our best design of those years". It describes how Catherine Bujold collected many items of furniture (Catherine's site is Sorellarium13, although they actually credit space1999.net here).
The article describes how the partition walls could be assembled or dismantled like Lego. Keith Wilson is quoted "The Moonbase would be what we imagined as the future: clinical, antiseptic, minimal. No colour except white could express this." The alien worlds were baroque, colourful and psychedelic in contrast to contained and icy habitat of the Alphans. Wilson is quoted "Being able to unleash my imagination, I recycled what came to hand, especially objects from discarded plastic foundries. Everything unusual I could find, I used it. In that sense, I think I was a pioneer of recycling and sustainability."
The article ends with a quote from Keith Wilson (also the pull-quote): "We wanted to create a future we imagined was possible. No one could guess what it would be, but many later became iconic details. Somehow we have traced the style of those years. Today when people think of that time, they identify with the series." It concludes with a quote from Catherine Bujold: "this design will always remain timeless and always evoke a future that I'm still looking for."
