Astronaut Grissom on level 3 in front of Liberty Bell 7 capsule
Astronaut Virgil I. (Gus) Grissom, suited up and ready to climb into Liberty Bell 7 spacecraft, poses for a picture. Backup pilot John Glenn is in the right corner of the view behind Grissom. The Mercury-Redstone 4 (MR-4) mission was scrubbed a few hours later due to unfavorable weather over the launch pad.
