@ianwalkerxx @NASAWebb After @NASAWebb reaches Lagrange point 2 in a few weeks, it will take ~5 months to cool down, align its mirrors & calibrate its instruments before the science begins: https://t.co/2RH2EXQX7a #UnfoldTheUniverse — PolitiTweet.org

@bricetune They have a much bigger cryogenic vacuum chamber at @NASA_Johnson that was used on the Apollo program and we tested our mirror and instruments there. The spacecraft (sunshield and bus) were built at Northrop Grumman and they were connected to the mirror/instruments there. (2/2) — PolitiTweet.org

@_Crazycrit @NASAWebb As Webb is orbiting L2, it's also moving around the Sun. Since Webb can only point to roughly half the sky at any given moment because it can’t look in the direction of Earth & the Sun, this affords Webb access to the entire sky over the course of a year: https://t.co/Fv0KXtzKLS — PolitiTweet.org
