[ExI] Nancy Grace Roman telescope was successfully launched

[John Clark]

*Just about one hour ago the Nancy Grace Roman telescope was successfully
launched from Cape Kennedy, its mirror has the same diameter as the Hubble
telescope, 2.4  meters, but its field of view is 100 times larger. Roman is
optimized for the near infrared so unlike Hubble it cannot see the
ultraviolet, and unlike Hubble it will not be in a near earth orbit, it
will be at the Lagrange 2 point, like the James Webb telescope. It won't be
fully operational until late this year or early next.   *
