Our Deputy Project Manager, Paul Geithner, joined @fcain for a live Q&A about #NASAWebb recently. Watch here:https://youtu.be/iX0iCqCTKzE

Although Paul Geithner mentions he (you) are involved in technical development of James Webb, how much James Webb will be able to determine the extent and composition of atmospheres of terrestrial especially potentially habitable planets including non-transiting like Proxima b?
Webb will be able to search for molecules like water & carbon dioxide in the atmospheres of terrestrial-size planets, either via transit observations or via orbital phase variations for non-transiting planets (where the bright day-side of the planet rotates in and out of view).
