The process consisted of lifting the payload into the spacecraft, performing a varity of shim, cable routing, and other measurements, and then removing the payload from the spacecraft. The steps leading up to this work included removing the guard tank vent line, rotating the tilt dolly and tilting the payload to vertical. Currently preparations are underway to fill the dewar to approximately 70 %.
