Like a latch made in heaven, @NASAWebb’s secondary mirror is now fully deployed and locked! The team remains focused as they work toward the final major milestone this week – deployment of the iconic honeycomb-shaped mirror.

@RuiaSamarth After Webb’s unfolding journey is complete, first images will come in about 6 months after launch (June 2022). During this period, the telescope will cool down, the instruments are calibrated, and the 18 primary mirror segments will align to work as a single mirror. — PolitiTweet.org

@JamesLundblad Webb’s instruments will provide wavelength coverage from 0.6 to 28 micrometers (or microns). The infrared part of the electromagnetic spectrum goes from about 0.75 microns to a few hundred microns. This means it will be able to see about 200 million years after the Big Bang. — PolitiTweet.org

@ssayakarol Webb’s 12 rocket thrusters use either hydrazine fuel or a special mixture of hydrazine fuel and dinitrogen tetroxide oxidizer. Learn more about the propulsion system here: https://t.co/dq6Ghf2Ixx — PolitiTweet.org

@SpetalsZuzu @peterframpton @NASASpaceSci Sounds like you dropped some science on 'em. If you're ever looking for more gravity activities to share with curious young minds, perhaps you'll find these... attractive. https://t.co/DbX10Bso8g — PolitiTweet.org

@OctoNerdGaming @NASASpaceSci We'll leave it to astronauts Terry Virts and Samantha Cristoforetti to comment on this fruit snack, but chew on this: the crew grows crops on orbit as part of ongoing space biology research.

Shields up! @NASAWebb has completed the tensioning of its tennis-court-size sunshield. This five-layered shade will protect the telescope from the heat of the Sun, Earth and Moon, helping it #UnfoldTheUniverse in infrared light.

@nachtsmeer The layers, each as thin as a human hair, are made of Kapton, a tough, high-performance plastic. Every layer is coated with aluminum, & the sun-facing side of the two hottest layers also have a doped-silicon (or treated silicon) coating to reflect the sun's heat back into space. — PolitiTweet.org

NASA @NASA

Why is @NASAWebb's sunshield shaped like a kite? In short, it's exactly the shape & size it needs to be. The iconic profile lets the telescope tilt back and forth to observe more of the universe. Plus, it helps radiate heat from the sides. Take a look: https://t.co/YhpDZdWLb8 https://t.co/TjCXoFivq9 — PolitiTweet.org

NASA @NASA

@JacksonBTT Splitting the sunshield into 5 layers allows heat to radiate out from between them, causing each successive layer to be cooler than the one below. The vacuum of space between each layer also acts as a great insulator. Learn more about the sunshield design: https://t.co/j1nRsAwHOL — PolitiTweet.org
