Infrared astronomy faces a gap

In late 2016 I noted that the James Web infrared space telescope was two years away (in this post) but it now seems that the launch has been pushed back to March 2021 at the earliest. This delay means that there will be a gap in infrared observation capabilities, as the Spitzer is set to cease operation over a year before that.

More information on this can be found on the Scientific American web site.
