(I learn something new every day— they are using water to regulate the solar-panel temperatures!)

to summarize…
-heat shield
-autonomous software continually sensing instrument function and orienting the craft
-cooling system
– “heat is not temperature” (a very interesting Factoid about energy transfer in space)

Made by Cobham Plc, in the UK.

“Cobham solutions featured on the Parker Solar Probe include: RadHard Databus Terminals, Low Voltage Digital Signaling (LVDS) circuits, Logic devices, eight varieties of Memory, Multiplexers, Pulse Width Modulators, Spacewire Transceivers and Voltage Regulators. These devices allow the spacecraft to withstand the extreme temperatures and radiation as it travels towards the Sun.”

Unfortunately, NASA bans all truth tellers from commenting at their site.

Can you expand on that a little bit? (thanks)

At least the other two franchises produce movies with coherent plots.
