This project investigates the feasibility of high altitude balloon based telescopes<\/strong>.<\/p>\n

A high altitude telescope could minimize emission and “seeing”\u00a0 from the Earth’s atmosphere enabling a relatively low cost mission.. This project focuses on the possibility of frost buildup on the telescope mirror. The upper atmosphere is simulated in a vacuum chamber (about one meter cube) that is cooled with liquid nitrogen and data is collected via webcam and thermoresistors.<\/p>\n

A mild cryo pump effectively prevents frost buildup.<\/p>\n
