A day in the life of a mountaintop telescope builder

When she’s in Chile, Margaux Lopez starts most days nine thousand feet below her place of work. At 6:30 a.m. she boards a bus to begin the steep climb from La Serena, Chile’s second-oldest city, to the top of Cerro Pachón, a mountain in the Chilean Andes. Why does she do this? Lopez is one of a team of engineers hard at work preparing for the arrival of the Legacy Survey of Space and Time (LSST) camera, the largest digital camera ever built for astrophysics and part of Vera C. Rubin Observatory.
