BLAST-TNG goes outside for communications tests – which were successful! Our team has been very busy over the past several weeks. We’ve cooled our 850 lbs. cryogenic polarimeter (red object in photo), mounted it back onto the telescope, and carried out numerous systems tests. We are nearly flight ready, and the one experiment ahead of us in the line-up – called superTIGER – was successfully launched yesterday. Fingers crossed for good launch conditions!
