The Ana Lani mission concept is from a joint team of scientists from Goddard, University of Washington, University of Michigan and University of Hawaii. The science objective is to generate a map of the mass distribution in the universe to find cosmological constants. The instrument consists of 12 modular foil mirrors, each with a 24-cm diameter and 1.7 m focal length. Although the pointing requirement is in arc minutes, the jitter requirement is 2 arc seconds over 20 second.

In addition to the general support provided while the mission was studied in the IMDC, ACS personnel performed analysis to show the feasibility of inertial pointing with a 5 degree sun pointing constraint, and defined the star tracker optimal location.
