<P> The launch is scheduled, and the space shuttle Daedalus successfully launches into orbit . They find the satellite but all agree it looks nothing like a communication satellite . They secure the satellite with the shuttle's loading arm and begin repairs, but soon find it houses six nuclear missiles, relics from the Cold War and a violation of the Outer Space Treaty . The mission is quickly put under secrecy . Frank discovers that the control system for the satellite originated from Bob's own files and was stolen by the KGB, and that the satellite's computers will launch the missiles at predetermined targets if the satellite falls out of orbit . NASA and the crew devise a plan to use the payload - assist rockets to push the satellite out of orbit and into deep space . However, as they prepare for this maneuver, one of the younger astronauts, Ethan Glance (Loren Dean), acting under Bob's original orders, tries to put the satellite into stable orbit himself, which is mistimed and sets off a chain reaction: the satellite collides with the shuttle, damaging most of the shuttle's computer systems and engines, destroying the solar panels on the satellite, and sending it faster into a decay orbit, while Ethan is knocked out and dragged along with the satellite . </P> <P> While Tank and Jerry tend to the other young astronaut Roger Hines (Courtney B. Vance), who suffered a concussion on the impact, Frank and Hawk make a space walk and reach the satellite in time to activate a booster rocket and slow down the orbit . As they see to Ethan, the two realize that there is no way to restablize the orbit of the satellite without power, and the only option is to have someone ride on the satellite as they fire the missiles' engines so that it falls into deep space . Hawk quickly volunteers to sacrifice himself, hoping that he will be able to land himself on the moon to fulfill his life's dream . After helping Hawk to rig the satellite for launch, Frank takes Ethan back to the shuttle to be tended to . Frank, Tank, and Jerry say their goodbyes to Hawk as he engages the rockets, successfully propelling the missiles away from earth . </P> <P> Frank, Tank, and Jerry now work to bring the shuttle back to earth, with the plan to achieve a low enough altitude to allow the shuttle to be evacuated over water since landing it would be difficult . Frank successfully pilots the shuttle to reenter orbit but with too fast a speed . After safely ejecting Ethan and Roger, Tank and Jerry stay with Frank regardless of the risk . Frank recalls a maneuver Hawk had used before, purposely stalling the shuttle to drop its speed quickly and allowing him to land the shuttle safely . The crew is welcomed back as heroes . Later, Frank talks with his wife Barbara and contemplates if Hawk made it to the Moon . The film ends with the Frank Sinatra song "Fly Me to the Moon", zooming in on the surface of the Moon showing that Hawk had indeed arrived, having died while peacefully watching the Earth . </P> <Ul> <Li> Clint Eastwood as Colonel Francis D.
