The Electromagnetically Isolated Global Signal Estimation Platform (EIGSEP) is an ambitious project, funded by the Gordon and Betty Moore Foundation, aimed at detecting the Cosmic Dawn of the universe by measuring the average brightness of the 21cm line of hydrogen through history.

To deliver the unprecedented levels of calibration needed to see this faint signal, it features a robotic, autonomous antenna element suspended 100 meters from all reflective objects—including rocks, metallic cables, and signal processing electronics. When observing, it hangs in a remote canyon far from human interference, but it is designed to be removed to maintain a pristine natural environment when not in operation.
