In a nutshell… It’s very cold It’s very dry The atmosphere is very stable Antarctica is the only place on earth set aside for science by international treaty Image: Daniel Luong-van

Typical twilight spectra at Dome A and Paranal Sims et al., 2012a

Craig Kulesa, 2013 Ridge A Median: 130 microns Best 10%: 60 microns

Ridge A. Top to bottom: dry-air only, best 10 percentile, best 25 percentile, median winter transmission. H2D+H2D+ [O III][O I] [C II] [N II] Sims et al., 2012

Deployment to Antarctica is one thousand times cheaper than space ($10/kg versus $10,000/kg) Image: John StoreyImage: ESA
