Riders To The Stars.

A group of highly qualified single men, including Dr. Richard Stanton (William Lundigan) and Dr. Jerry Lockwood (Richard Carlson) are recruited for a top secret project. They undergo a series of rigorous physical and psychological tests. Stanton becomes attracted to the beautiful Dr. Jane Flynn (Martha Hyer), one of the scientists testing the candidates. The scientists want to recover samples before they enter the Earth's atmosphere to discover how the meteors' "outer shell" protects them.
