The Agencia Espacial Imperial de Atlia (AEIA) or Imperial Space Agency of Atlia has its background in Prince Luis' early efforts to observe the 2017 solar eclipse on behalf of the Kingdom of Atlia by creating the VIDEO CAELO, a rudimentary eclipse projector; as well as the efforts to send the name of the Kingdom of Atlia to Mars in the Mars 2020 mission that took the Perseverance rover and its Ingenuity explorer helicopter to the red planet.

The Agency was conceptualized on 5 January, 2024 A.D. and officially created on 8 April, 2024 A.D. by Imperial Proclamation No. 18. The first project of the AEIA was the recording of the Solar Eclipse on the same day, with successful results in Nova Atlium, Kingdom of Atlia and the Territory of Appledore-Lutecia, Kingdom of the Southern Star. This was part of the Northern Star Program, made in joint effort with the Tozarian Empire and the North Sea Empire.
