Opening of the cryocover

The opening of the cryocover is planned for Sunday 14 June. By then the telescope will have reached a temperature of about 120 K. The opening will enable the instruments inside the cryostat for the first time to see out to the real sky. You can get a very approximate idea of what is going to happen by watching the video below, available in YouTube, where the opening of the cryostat lid is shown in slow motion during one of the cryogenic qualification tests carried out by Austrian Aerospace and EADS Astrium at Friedrichshafen, Germany.
