B-roll – Public Visits
19 August, 2020 / Read time: 1 minute
ALMA is open every Saturday and Sunday morning to members of the public who want to visit its facilities located in northern Chile (50 km from San Pedro de Atacama). Only those visitors who are registered in advance may visit the ALMA Operations Support Facility (OSF, 2,900 meters altitude), where ALMA personnel work and where visitors can observe the control room, laboratories and antennas under maintenance and an antenna transporter, if are available. For safety reasons, operations on the Chajnantor Plateau (the Array Operations Site, or AOS, where the antennas are located) are not open to visitors, due to the location at 5,000 meters above sea level.
