The DSN antennas have been carefully placed at three distinct sites across the planet, each about 120 degrees apart.
Because the Earth revolves, the network of antennae enables scientists to communicate with Webb at nearly any time of the day.
“On average, the Webb mission operations center connects with the observatory at least 2-3 times in a 24-hour period. There are mission planners at STScI where the Mission Operations Center is located, mission schedulers at JPL, and of course at the DSN complexes. The mission planners at STScI work together with the mission schedulers at JPL to create contacts with Webb,” said Kari Bosley, the lead Webb mission planner at the Space Telescope Science Institute .
“We use Ka-band to downlink stored science and engineering data and some telemetry from the spacecraft. If we used S-band to downlink data, it would take many days to download each day’s data. With Ka-band, it takes much less time, and we can usually completely download all of the stored data in a couple of hours,” explained Bosley.
