At one time, these bleak landscapes were standard sci-fi territory but I think Malex's folio is unique in terms of fetish art. Modern artists, helped by the power of computers, seem to have moved on to more fantastical worlds and creatures in lusher settings more akin to earth.
Malex's spacemen all appear totally naked, ramping up the hostile threat of alien worlds and airless space. He doesn't appear to have explored the erotic power of tight-fitting spacesuits which have always interested me. I have published two astronaut pictures here 'Astronaut by Mitchell'
and 'Space Cadet Chastised' by Mitchell
