@WangnickS Debris isn't an issue a million miles away where we will orbit L2, and space is big so impacts from larger objects (asteroids, meteors) won't be an issue. We do expect tiny micrometeorite impacts, and the telescope was designed and tested for this. — PolitiTweet.org

@CougerMom @NASAWebb’s mirrors are made of beryllium because it's stable across a a wide range of temperatures. They’re then coated in a thin layer of gold to improve the mirror's reflection of infrared light. Here's more info: https://t.co/6eUrI3tOFQ — PolitiTweet.org

@WangnickS The sunshield has special seams to limit meteorite damage. Testing showed that micrometeoroids have negligible effects on the telescope's beryllium mirrors: https://t.co/Jx1ThKYsPL — PolitiTweet.org
