ALMA antennas and Front End Service Vehicle

The Front End Service Vehicle raises 20 feet high to service a 12-meter Japanese ALMA telescope in the active array at 16,500 feet elevation in northern Chile. The FESV is based on the design of an airline catering truck. It is 36 feet long, 8 feet wide, and weighs 26 tons and has a cargo hold that can keep receiver cryogenics cold and safe.
