In the early years of rocketry at Caltech, there was no figure more influential than the Chinese cyberneticist Qian Xuesen. Then, in 1955, the United States repatriated him to China, suspecting him of being a spy.

Qian returned to China to become the father of the country’s space-launch vehicle and ballistic-missile programs and contributed greatly to the “Two Bombs, One Satellite” nuclear weapons and space project. And his efforts were not wasted—on 9 March of this year, the People’s Republic of China launched its 300th Long March rocket, which put China’s 506th spacecraft into orbit.

For a deep dive into the engineering behind the James Webb Space Telescope, see our collection of posts here.

When the James Webb Space Telescope (JWST) reveals its first images on 12 July, they will be the by-product of carefully crafted mirrors and scientific instruments. But all of its data-collecting prowess would be moot without the spacecraft’s communications subsystem.

The Webb’s comms aren’t flashy. Rather, the data and communication systems are designed to be incredibly, unquestionably dependable and reliable. And while some aspects of them are relatively new—it’s the first mission to use Ka-band frequencies for such high data rates so far from Earth, for example—above all else, JWST’s comms provide the foundation upon which JWST’s scientific endeavors sit.
