Officially the Apollo missions ended with Apollo 17. However, there are claims that the Apollo missions continued in secrecy under “”. Supposedly, the Apollo missions 18 and 19 found evidence for, with the loss of Apollo 19 due to a purported collision. The Apollo 20 mission is said to have made a successful landing on the, not only recovering alien technology, but also an extraterrestrial biological entity (EBE).

Alleged footage
In 2007, William Rutledge posted videos on YouTube, claiming to show parts of the Apollo 20 mission, including footage of structures on the moon, as well as an EBE resembling a female humanoid. Rutledge was supposedly interviewed by UFO researcher, Luca Scantamburlo, about the footage and the Apollo 20 mission.

Rutledge claimed that the Apollo missions continued under Project Horizon, a supposed joint US/Soviet venture in 1976, that was for the record, a program "rejected" by Eisenhower. Apollo 20 allegedly landed in the Delporte-Izsak region on the. They allegedly found a crashed “ancient spacecraft” around two and a half miles long, and the remains of a nearby old city that the crew dubbed “Moon City”. They also allegedly recovered a humanoid EBE that resembles a human female with Asiatic features, having the impression of a on her forehead. They named her "Mona Lisa".

Project Horizon was not a NASA program, but a project. At the time, USAF was involved in studying foreign technology, in particular, Russian. Alleged US Air Force projects also included the N1 project, AJAX plane project, the MIG Foxbat 25 and the MOL-Gemini project.

Project Horizon
Project Horizon was a 1959 study to determine the feasibility of constructing a scientific military base on the Moon, at a time when the U.S., , and had total responsibility for U.S. space program plans. On June 8, 1959, a group at the (ABMA) produced for the Army a report titled Project Horizon, A U.S. Army Study for the Establishment of a Lunar Military Outpost. The project proposal states the requirements as:

"The lunar outpost is required to develop and protect potential United States interests on the moon; to develop techniques in moon-based surveillance of the earth and space, in communications relay, and in operations on the surface of the moon; to serve as a base for exploration of the moon, for further exploration into space and for military operations on the moon if required; and to support scientific investigations on the moon."

The permanent outpost was predicted to be required for national security "as soon as possible", and to cost $6 billion. The projected operational date with twelve soldiers was December 1966. However, its argued that Horizon was rejected by President, as primary responsibility for America's space programs were transferred to.
