Spies discover that the Red Chinese have built a "doomsday machine" capable of destroying the surface of the Earth, and that they plan to use it within a matter of days. Meanwhile, Project Astra, a manned U.S. space mission to Venus, is in its final hours before launch when it is taken over by the military and nearly half of its all-male crew is replaced by women. The reason for this becomes apparent when, shortly after Astra leaves orbit, the Earth is completely destroyed in a global cataclysm! Is the human race doomed? What dangers and wonders await the crew of the Astra on their journey to Venus? Written by yortsnave

When Katie accidentally hits the button to open the outer airlock door, the differential pressure should have sucked both her and Captain Mason out the hatch, instead of letting them float inside while their bodies suffered no greater injury than passenger nosebleed on a first-generation airliner. To say nothing of the fact that no airlock system, even during Project Apollo, would be that easy to open by accident. See more »


Danny: We're picking up a bomb of static. Must be due to the Van Allen Belt.

An Unknown Cast In A Nothing Movie
22 September 2010 | by sddavis63See all my reviews

About six minutes goes by before a single word is spoken in this. From that point on you often find yourself wondering why they started the dialogue - or even the movie for that matter. Basically, this is a bunch of unknown actors (although Mike Farrell in his pre-MASH days pops up as a reporter who speaks 2 or 3 lines) fighting their way through a weak script and ending up with a movie that's - well - pretty bad. Basically, China has invented some sort of weapon that can destroy the earth, and a mission to Venus is sent off early (with three women replacing three crew members) in order to avoid the destruction. The new crew's mission? To procreate and make sure humanity survives the destruction. There were a handful of moments that created uncertainty, and a real question of who was going to end up surviving once it was discovered that only 3 of the 7 in the crew could actually get to Venus. But then a bad movie turns dreadful with an ending that - to me at least - made absolutely no sense whatsoever. This really isn't worth wasting your time with. Really. It isn't!
