Engineer Mike Menzel at @IntrepidMuseum's Space & Science festival: "#Webb will follow the Earth around the Sun at a point called the Second Lagrange Point - and by putting it there, one umbrella is going to block out the light from the Earth, the Sun, and the Moon." #JWSTpic.twitter.com/TIGmdk0VmV

Can Webb be pointed at Mercury at the time of ESA probe encounter?
Hi - unfortunately, we can't view Mercury at all because it is so close to the Sun, which is extremely hot and bright, and would swamp our heat-sensitive telescope.
