Antenna Maintenance at an Altitude of 5000 Meters


Antenna Maintenance at an Altitude of 5000 Meters

ALMA technical staff members perform maintenance on a Japan-made 7-meter antenna using a cherry picker. This is the ALMA Array Operations Site at an altitude of 5000 meters. It is not easy to perform maintenance in this environment with glaring sunlight, high winds, low temperatures, and low oxygen. The technical staff performs daily maintenance carefully so that ALMA can efficiently carry out the many observation proposals it accepts from astronomers around the world.
