Serenitatis Base is a fictional lunar base in Mare Serenitatis, mentioned in Arthur C. Clarke’s 1951 short story, The Sentinel.

The SentinelEdit

In The Sentinel, two heavy freighters fly in supplies and equipment to Mare Crisium, from the main base at Serenitatis. An ancient pyramid, twice the size of a man, is discovered at Crisium by the narrator. This was the inspiration for the TMA-1 in Kubrick and Clarke’s joint 2001 project.[1]


Serenitatis Base is Britain’s foothold on the Moon. The base appears in World of 2001. The design for Serenitatis Base is loosely derived from a JSC Advanced Programs Office concept from 1989.[2]
