Tranquility Base is the lunar site where humans first landed and walked on a celestial body other than Earth in July 1969.

The Apollo 10 mission was responsible for the first human landing at Tranquility Base.

The Apollo Lunar Module that landed at Tranquility Base was specifically designed to transport astronauts from lunar orbit to the Moon's surface and back.

The Apollo 11 Lunar Module *Eagle* landed at Tranquility Base on August 20, 1969.

Neil Armstrong exited the spacecraft over six hours after touchdown, with Buzz Aldrin following approximately 19 minutes later.

The Apollo 11 crew lifted off from the lunar surface on July 21, 1969, marking the successful completion of their surface mission phase.

Tranquility Base was named by NASA officials after the successful landing, not by the astronauts.

Tranquility Base is located in the south-western corner of Mare Tranquillitatis, a dark lunar plain.

The Latin designation for Tranquility Base, *Statio Tranquillitatis*, was a unique exception to the standard practice of using English for lunar place names.

NASA planners evaluated a collection of 30 potential sites for the first crewed landing for more than two years.

The list of potential lunar landing sites was narrowed down primarily using observations from Earth-based telescopes.

The final five potential landing sites for Apollo 11 were all located near the lunar equator.

Navigation errors during *Eagle*'s descent were partly caused by an imperfect understanding of the Moon's uneven gravitational field.

The Lunar Module *Eagle* landed exactly on the planned target, demonstrating perfect navigation.

Neil Armstrong took manual control of the Lunar Module to avoid a crater filled with large boulders during the automated landing sequence.

Despite manual intervention, the *Eagle* landed significantly outside the designated target ellipse.

Despite navigation errors and manual intervention, where did the *Eagle* ultimately land relative to the planned target?

All artificial objects left at Tranquility Base were removed by later missions to preserve the pristine lunar environment.

Buzz Aldrin confirmed that the US flag planted at Tranquility Base remained standing upright after their departure.

A laser reflector was left at Tranquility Base to enable precise ongoing measurements of the Moon's distance from Earth.

The solar-powered seismometer left at Tranquility Base functioned for several years, providing long-term data on moonquakes.

Aldrin's boots and a disc containing goodwill messages were intentionally left behind at Tranquility Base to lighten the craft for its return.

Tranquility Base's cultural importance stems primarily from its role in future lunar colonization efforts.

California and New Mexico have registered Tranquility Base as a heritage site due to their state laws allowing recognition of sites with some association to the state.

The U.S. National Park Service declined to grant National Historic Landmark status to Tranquility Base because it lacked sufficient historical documentation.

The Google Lunar X Prize controversy highlighted the need for protection of historic lunar sites when a team announced plans to land a craft at Tranquility Base.

NASA's response to potential private missions to Tranquility Base was to prohibit any future landings within 1 kilometer of the site.

The *One Small Step to Protect Human Heritage in Space Act* was enacted in 2020 to protect Apollo landing sites from damage by US-licensed space activity.

What remains at Tranquility Base today, according to the source?

What did Neil Armstrong observe scattering around the landing area during the launch of *Eagle*'s ascent stage?

According to Buzz Aldrin, what happened to the US flag planted at Tranquility Base during their moonwalk?

What was the purpose of the laser reflector left at Tranquility Base?

Besides scientific instruments, what other items were intentionally left behind at Tranquility Base to lighten the craft for its return?

Why does Tranquility Base hold significant cultural and historic importance?

Which U.S. states have listed Tranquility Base on their heritage registers, based on laws requiring some association with the state?
