This photo gives a "worms eye" view of a robot arm
holding a surrogate or simulated mirror segment (black hexagonal shape) for
NASA's James Webb Space Telescope. The arm is placing the surrogate into the
test backplane structure in the clean room at NASA's Goddard Space Flight
Center in Greenbelt, Md. The holes in the test backplane aren't wormholes, but
the openings in the structure that will support the Webb telescope's primary
mirror segments.
The yellow structure supports a robot arm that will be used
to install the 18 mirror segments on the Webb telescope's primary mirror
backplane.
