NASA’s Nancy Grace Roman Space Telescope team has begun integrating and testing the spacecraft’s electrical cabling, or harness, which enables different parts of the observatory to communicate with one another. Additionally, the harness provides power and helps the central computer monitor the observatory’s function via an array of sensors. This brings the mission a step closer to surveying billions of cosmic objects and untangling mysteries like dark energy following its launch by May 2027.
“Just as the nervous system carries signals throughout the human body, Roman’s harness connects its components, providing both power and commands to each electronic box and instrument,” said Deneen Ferro, the Roman harness project development lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Without a harness, there is no spacecraft.”
