Apollo 15: Mobility Expanded, Constraints Remained

Apollo 15’s improved A7LB suits added joint flexibility and consumables supporting seven-hour EVAs and a five-mile walkback.

Apollo 15 stowed the Buddy Life Support System on its rover, preserving a contingency for extended EVA operations.

Apollo 15 crews still had to stay within walkback limits; nearing that limit after Spur Crater samples forced them to hurry.

Falcon’s landing tilt impaired Portable Life Support System recharge, causing false warnings and delaying Apollo 15’s second EVA by 30 minutes.
