"Building the James Webb Space Telescope" by @paulgeithner is in the November 2021 issue of @SkyandTelescope magazine

NASA Admin @SenBillNelson, at Apollo 17's 50th anniversary at the Nat'l Academies, laid out plans for NASA's next Great Observatory: "Habitable Worlds Observatory" will study Earth-sized planets around Sun-like stars, plus transformative astrophysics and planetary science!♥️🚀🔭

NASA, Webb Telescope Partners Receive Aviation Week Grand Laureate Award nasa.gov/feature/goddar…

We built a marvelous machine that works, and works really well: arxiv.org/abs/2207.05632

We engineered this machine right, and it works beautifully. Whenever we look at nature with a new tool with new capabilities, we always discover amazing things. This is the promise of #Webb : via @NYTimes nytimes.com/2022/07/12/sci…

Tune in July 12th for the reveal of #Webb @NASAWebb first science: blogs.nasa.gov/webb/

Tune-in July 12th for revelation of #JWST @NASAWebb first science observations: nasa.gov/press-release/…

🗓 July 12 — Save the date! Count down with us to the big reveal of Webb’s first full-color images and spectroscopic data: go.nasa.gov/3M9PeT1 Want a hint on how Webb will #UnfoldTheUniverse? Read more: go.nasa.gov/3aeMupU

In late May, Webb sustained a dust-sized micrometeroid impact to a primary mirror segment. Not to worry: Webb is still performing at a level that exceeds all mission requirements. Our first images will #UnfoldTheUniverse on July 12: go.nasa.gov/3mvyZoJ

@paulgeithner update on #Webb @NASAWebb on #TwitterSpaces today at 12:15pm EDT: twitter.com/i/spaces/1vAxR…

We have merely completed image stacking - we haven't even started coarse and fine phasing - and we already have an amazing telescope: blogs.nasa.gov/webb/2022/02/2… @NASAWebb #UnfoldTheUniverse

“Macro-deployments” are complete! Next comes moving all the primary mirror segments + secondary mirror starting Jan 11, then months of optical alignment and instrument calibration #unfoldingtheuniverse via ⁦⁦@nytimes⁩ nytimes.com/2022/01/08/sci…

#NASAWebb is fully deployed! 🎉 With the successful deployment & latching of our last mirror wing, that's: 50 major deployments, complete. 178 pins, released. 20+ years of work, realized. Next to #UnfoldTheUniverse: traveling out to our orbital destination of Lagrange point 2!

We've been hearing you loud and clear: Why doesn't Webb have cameras for its journey to #UnfoldTheUniverse? It sounds like a no-brainer, but there's more to it than meets the lens. Thread ⬇️

This is it: we’ve just wrapped up one of the most challenging steps of our journey to #UnfoldTheUniverse. With all five layers of sunshield tensioning complete, about 75% of our 344 single-point failures have been retired!
