Today we celebrate the Hubble Space Telescope’s silver anniversary of 25 years in space by unveiling some of nature’s own fireworks. This spectacular and famed Hubble image shows newborn stars emerging from “eggs”.
More than 10 years ago, Hubble was almost lost. In year 2002 the STS-109, the fourth Hubble Space Telescope-servicing mission, was set out to rescue the Telescope. The crew of STS-109 mission successfully upgraded the telescope’s systems over the course of consecutive spacewalks, leaving it with a new power control unit, improved solar arrays, the new Advanced Camera for Surveys, and an experimental refrigeration unit for cooling the dormant Near Infrared Camera and Multi-Object Spectrometer. Astronaut Rick Linnehan, who was instrumental on this most challenging mission, completed his third flight aboard Columbia. Linnehan performed four spacewalks totaling 21 hours and 9 minutes outside Space Shuttle Columbia. STS-109 orbited the Earth 165 times and covered 3.9 million miles in just over 262 hours. On Ricks very first mission (STS-78) in 1996 he and his crew served as test pilots exploring and exercising using YoYo. Since then he has been involved with numerous test studies and investigations, and is a frequent user of YoYo even when he is off duty in space. Pictures show Rick in one of several space walks to fix the Hubble, and flanked by Per Tesch, founder and senior advisor of nHANCE and YoYo Technology, and Per Övermo of the Tesch-Övermo Foundation.
