There have been rumors about the future of Star Trek: Enterprise, the fifth chapter in the Star Trek saga, and it is believed that many of the cast are expecting its current fourth season to be its last. However according to Leslie Moonves, co-president of Viacom (which owns UPN and Paramount), no decision has been made on the future of the show.

An attempt to save the series through a year-long arc was a mixed blessing - - ratings continued to dwindle while critics applauded the story. But that hasnt stopped the creators from trying one last time to boost the ratings by bringing the series closer to the Kirk days.

"It's hard to say right now. The ratings aren't great. It may be a franchise that should be rested a year or two," Moonves recently said. "I know the diehards are not in favor of that, but I think if we rested a year or two, it might be a better thing. But we'll see what happens the rest of the year."

Moonves also stated that the future of the show would ultimately depend on how it performs for the rest of the season, which will include the infamous "mirror universe" and a long-awaited answer to the riddle of Klingon foreheads.

The rumors currently circulating about the series state that the number of episodes requested by UPN has been slashed, and that Scott Bakula (Capt. Jonathan Archer) is ready to step away from the captain's chair regardless of the show's future. Speaking to Sci-Fi Wire however, Bakula said that nothing could be further from the truth.

"I'd hate to see it end this year," he said. "We're waiting to hear. It's a funny place to be in. I love the crew. I love the cast. The work situation has been tremendous. We're doing creative work, still, I think. And I know we have a lot of fans out there. So ... as a television gig would go, it's a great, wonderful gig. And I'm loving it. So I will be disappointed. But we'll see. It ain't over until it's over."

Bakula also mentioned that if UPN decided that the future of the network has no home for Star Trek, it is hoped that the network will give the writers enough time to develop a finale to the series to round off existing plot threads. The writers are currently working on the final two episodes of the season, so if any finality is to come to the series, the announcement will need to be made soon.

"I don't know. They're not under any obligation to let us know. They can do whatever they want to do, and they may ... We don't call those shots," Bakula said. "The indication was and has been often that this would be our last season. But then we were told we were going to get an early indication of that so we could wrap the show up in a nice way. And here we are, it's the end of January, and I know that they've broken stories through the 21st [episode]."

"Enterprise" wraps production in March. An announcement about cancellation could be delayed as late as May.

"Star Trek: Enterprise" airs Fridays at 8 p.m. ET on UPN.
