In Part 2 of the series we looked at Why Use clean rooms for Satellites?

Here we look at if or how SpaceX use clean rooms.

What About SpaceX?

Many have watched SpaceX build rockets in tents and open construction bays. These are not clean rooms, so if they don't need them, why do others?

SpaceX does, in fact, use clean rooms for some parts of their satellite manufacturing, particularly for sensitive components and final assembly stages, although their approach might differ in scale or specifics from traditional aerospace practices.

The SpaceX Way

While SpaceX is known for its sometimes less accepted methods, they do use clean rooms where it counts.

For instance, in the production of sensitive satellite components like those for Starlink, clean room conditions are maintained to ensure the reliability and performance of these satellites.

Dragon spacecraft are also still built in clean rooms where the a high standard kept during manufacturing.

Why Clean Rooms Are Still Necessary?

Even with SpaceX's more rapid production cycles, they are still building some components that need a clean environment. Any contamination could affect performance, particularly over the long term in space.

They still need to comply with certain industry standards for satellite launches, especially when these satellites are meant for commercial or governmental use where they are part of the delivery standard.

While SpaceX might push the boundaries in such areas as Starship rocket production, satellites, particularly those like Starlink, require high reliability to maintain network integrity. Clean rooms help reduce risks of failure due to contamination.

Some Change

SpaceX might not use clean rooms in the same way some other manufacturers do. They might use localized clean areas or rapid assembly methods in controlled environments for specific tasks to reduce the need and speed up the process, but they still use them in some cases.

While SpaceX might have adapted the clean room concept for efficiency, the underlying need for controlled, clean environments in satellite manufacturing still seems to be required due to nature of satellite functionality and durability.

Their approach might be optimized or streamlined, but the principle of minimizing contamination is still employed.
