In a report published on 25 September, NASA confirms that the ground stations intended to receive Roman’s science data have passed their tests. Checks took place from 7 to 17 September: first in Japan, then at White Sands in New Mexico, and finally near New Norcia in Australia. [1]

The network brings together NASA, JAXA and ESA antennas and tested links at up to 500 megabits per second, a measure of how much data moves over time. The mission expects to receive around 1.4 terabytes a day once science operations begin, which NASA places by early 2027. [1]

Rain and link conditions can weaken the signal. The distributed network and a system that requests missing data again are designed to manage these interruptions. The achievement concerns communication capacity verified in tests; it does not mean the entire science campaign has already taken place. [1]
