With a dish this big, we can stay connected even a million miles away in space! The Nancy Grace Roman Space Telescope’s high-gain antenna has completed a series of tests at NASA's Goddard Space Flight Center. One of those tests was in the radio-frequency anechoic test chamber, ensuring Roman’s signal will be crystal clear back here on Earth. The foam spikes lining the chamber make sure there is minimal interference during testing. Next steps: the antenna will be attached to its articulating boom assembly in the Goddard clean room!

The antenna is a large grey dish, about the height of a refrigerator, facing slightly to the left. There is a small circle that is elevated in the middle of the antenna disk by six metal strips. The antenna is mounted to a base that is also covered in blue spikes.

There are small faint black circles that cover the disk. Image 3:Close-up of the spiked-shaped blue foam covering the walls of the chamber.
