I am looking for online catalogs of hardware either semi-COTS or full COTS (radios, antennas, thrusters, command and data handing boards, batteries, attitude control, etc...) that can be used in space applications. I found CubeSatShop.com, however, it only pertains to CubeSats and some SmallSat systems. Is there any other large online catalogs of parts for either/or CubeSats, SmallSats, Rovers, LargeSats, etc...?

Also I've been looking for a large list of spacecraft/rover scientific instruments, however, I have not been able to find such a database. Any recommendations?

The best and most complete spacecraft/satellite parts shop I've ran across is satcatalog.com. Satcatalog appears to have a large selection of COTS and semi-COTS hardware for CubeSats, SmallSats, and even medium/large satellites. Cubesatshop is another decent one, however I've found satcatalog.com to be far better, since they offer more variety and have better search tools.

TLDR: Largest Spacecraft Shop: SatCatalog.com

Largest one that I am aware of
