Roman Systems Infographic
This infographic shows the two major subsystems that make up NASA’s Nancy Grace Roman Space Telescope. The subsystems are each undergoing testing prior to being joined together this fall.
Two Systems, One Observatory
NASA’s nearly complete Nancy Grace Roman Space Telescope is made up of two major subsystems. The left image shows the inner portion, SCIPA. It consists of the spacecraft that will deliver the observatory to its place in space and enable it to function while there, along with the integrated payload assembly (the telescope, instrument carrier, and two instruments).
The right image shows the outer part, called OSD. It is made up of the outer barrel assembly, solar array sun shield, and deployable aperture cover –– components that will shade, power, and protect the telescope and instruments. Technicians built the subsystems simultaneously and are running each through a suite of tests prior to joining them together.
Same as above, but with acronyms more present in the labeling.
