Astronaut Grissom climbs into Liberty Bell 7 capsule to begin MR-4 mission
Astronaut Virgil I. (Gus) Grissom, suited up in a newly designed pressure suit, is assisted as he climbs into Liberty Bell 7 spacecraft. Behind him backup pilot John Glenn watches the insertion. The Mercury-Redstone 4 (MR-4) mission was scrubbed a few hours later due to unfavorable weather over the launch pad.
