NASA Glenn Engineer Highlights Research for Hubble Servicing Missions 

April 24 marked the 35th anniversary of the launch of NASA’s Hubble Space Telescope. The iconic space observatory remains a household name —the most well-recognized and scientifically productive telescope in history. Engineers at NASA’s Glenn Research Center in Cleveland played a significant role in how the telescope functions today.

NASA Glenn researchers assisted in all five Hubble servicing missions by testing damaged insulation, determining why it degraded in space, and recommending replacement materials.  

One of those researchers, Kim de Groh, senior materials research engineer, shared some of that research in a special presentation at Great Lakes Science Center, home of the NASA Glenn Visitor Center, in Cleveland on May 8. She chronicled her Hubble experience with a presentation, a show-and-tell with samples directly from the telescope, and a Q&A addressing the audience’s Hubble-related questions.
