Ground Data System (GDS)
Here they use Python, Flask, Javascript, HTML and CSS.

A GDS is the “Ground Data System” that supports large-scale embedded systems by allowing operators to interact with the embedded system.

Any data being sent from a ground computer to the spacecraft, or vice versa, has to passes through a GDS
