The satellite is intended primarily for technology verification in space, main test piece being UV light diodes, intended for removal of static charge from the proof mass. Proof mass experiment is expected to pave the way to engineering of gravitational reference sensor (GRS) of drag-free spacecraft. This devise has an applications for the tentative Laser Interferometer Space Antennagravity wave detector.[2]
Launches are separated by dots ( • ), payloads by commas ( , ), multiple names for the same satellite by slashes ( / ). Cubesats are smaller. Crewed flights are underlined. Launch failures are marked with the † sign. Payloads deployed from other spacecraft are (enclosed in parentheses).
