Launch date delay

On Sept 28th [2017], news article announced launch date has been delayed from October 2018 to March-June 2019 https://www.nasa.gov/feature/nasa-s-james-webb-space-telescope-to-be-launched-spring-2019

"NASA’s James Webb Space Telescope now is planning to launch between March and June 2019 from French Guiana, following a schedule assessment of the remaining integration and test activities. Previously Webb was targeted to launch in October 2018."

resolution

The angular resolution of a telescope is the wavelength divided by the linear aperture. The James Webb is bigger than the Hubble, but it's instruments see longer wavelengths. Consequently it does not have better angular resolution. Instead of writing that it has ""greatly improved resolution"", the article should say it has better resolution in the infrared.--Tedweverka (talk) 14:38, 4 January 2020 (UTC)[reply]

Could we have a picture showing how the mirror folds up?

I know there are quite a lot of pictures in the article already, but maybe one could be squeezed in to illustrate this fairly important design feature. All this talk about it being made in 18 segments so it can fold up had me thinking it was something much more complicated than it actually is. At any rate, I couldn't find any good ones on Commons, so it would be nice if some kind person could upload a few there. Like the ones here or here, for example. 80.225.163.175 (talk) 03:09, 26 January 2020 (UTC)[reply]

Incorrect image caption. First image.

Why does the first image of a folded up telescope say “ A rendering of the James Webb Space Telescope with its components fully deployed”. It doesn’t look very deployed to me. Coolcato (talk) 21:25, 24 April 2020 (UTC)[reply]
