@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

@bricetune As big as the vacuum chamber at Goddard is, it isn't big enough for all of Webb! We did test our instrument module there, but after that we had to move the hardware to NASA Johnson. (1/2) — PolitiTweet.org

@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
