Mission of the Darians is an episode from the end of the first series of Space: 1999.
Survivors of a dying world have been adrift in their enormous spaceship for over 900 years; so long that some of them have de-evolved back to savagery and no longer even understand where they are. But not all of them. Take these chaps.
It's been a long time since I watched this so I don't quite recall how it all pans out but I'm sure there are some really good Space:1999 fan sites out there that will tell you all about it. Here, we're just interested in the spacesuits.
What we have before us are a couple of Moon Zero Two spacesuits sprayed silver with some nice black detailing. The eagle-eyed might even spot that one of the helmets is actually from Gerry Anderson's own UFO series. The story has it that when they came to hire them they couldn't find two of the MZT ones which isn't all that surprising given that the helmets had careers far more varied than the suits and they were separated quite early on. Interestingly its the UFO helmet with the extra box shaped bit on the top of which I'm fairly certain there was only ever one. This may be its latest and last appearance documented so far.
Broadcast in October 1975 but filmed in January of that same year, these dates may or may not help us with a mysterious little appearance of possibly the same two suits from one of those charming and ever so slightly spooky Public Information Films... off which more will be blogged soon.
