key term - Lunar roving vehicle

Definition

The lunar roving vehicle (LRV) is a battery-powered, four-wheeled rover used during the Apollo missions to explore the Moon's surface. Designed to transport astronauts and equipment, the LRV expanded the range of lunar exploration, allowing crews to travel farther from their landing sites and conduct more extensive scientific investigations. Its development showcases the advancements in aerospace engineering and technology that were pivotal during the space race era.

5 Must Know Facts For Your Next Test

1. The lunar roving vehicle was first used during the Apollo 15 mission in 1971, with subsequent missions Apollo 16 and Apollo 17 also employing it for lunar exploration.
2. Each LRV was capable of carrying two astronauts along with scientific equipment and could travel up to 8 miles per hour on the Moon's surface.
3. The LRV was equipped with a television camera to transmit live images back to Earth, enhancing public engagement with the Apollo missions.
4. Designed to operate in harsh lunar conditions, the LRV featured a lightweight aluminum frame and was able to traverse rugged terrain and steep slopes.
5. After its use on the Moon, all three lunar roving vehicles remain on the lunar surface, serving as historical artifacts of human exploration.

Review Questions

• How did the lunar roving vehicle enhance the capabilities of astronauts during their Apollo missions?
