Challenges
Mass production and industrialization: The industry has geared up over decades to supply radio equipment such as phased-array antennas and hardware on satellites. Shifting the production to a new technology, and producing to scale is a challenge.
The technology has to contend with the atmosphere: Scintillation and turbulence mix up the wavefront ...

A hemispherical resonator is an example of a mechanical gyroscope that has no bearing parts and for practical purposes no moving parts either. See the Wiki page here.
I actually find the description of the principal of operation there a little hard to follow so I've just taken the black box principle, that the vibration patterns in the surface respond to ...

EEE-INST-001 and EEE-INST-002 are the guidelines for COTS parts screened for space service levels 1, 2 and 3. These assume you will perform functional screening to eliminate infant mortality and that you have a good idea of the high reliability service life duration.
I designed, qualified, installed and verified FO on the space station. All electronics ...

Standard commercial optical fibers could be used for data transfer on the Moon or Mars, but they may have a shorter life span than on earth and worse signal quality.
The radiation does have an impact on the molecular bonds of the optical fibers which can cause signal degradation. The phenomena is called "Radiation Induced Attenuation" for which you can find ...

There is, kind of. The US Military has a number of standards, called mil specs, which are required for certain components in certain kinds of environments. Among these is IEST-STD-CC1246D, which specifies cleanliness requirements for space hardware, MIL-STD-883 for electronic environmental concerns, and especially MIL-STD-1540D, which is entitled "PRODUCT ...

In Europe this is covered by the European Space Components Coordination. Among other things, they maintain a list of components that are qualified for use in ESA missions in agreement with standard "ECSS-Q-ST-60, Space Product Assurance - Electrical, Electronic and Electromechanical (EEE) Components".
On the ESCIES website (European Space Components ...
