On sale THIS WEEK to be more precise: the tenth issue of MARVEL UK's ill-fated science fiction weekly FUTURE TENSE.
STAR TREK: THE MOTION PICTURE snatched the coveted cover slot for the fourth time in five weeks, having appeared on the front of issues 6 (the first to include the strip) to 8. The Micronauts broke the run the previous week but Trek was back for this issue before taking an extended break until the nineteenth issue. It continued to appear in each issue.
1981 was a turbulent year for FT... not least because it was cancelled at the end of the year. Late January saw the merger of FORCES IN COMBAT, bolstering FT's line-up with Rom the Space Knight. March saw the merger of VALOUR, shoehorning Conan and Weird World into what was still officially an SF comic. That combo continued through to July when FT was rebooted again, now as a monthly. The new incarnation ran for only six issues before folding.
