The emerging space technology
In the modern world, science and technology are fast-growing things, and as we can see a lot of new space technologies are about to be produced or invented. Which one do you expect the most and which one do you think might be the most useful for humans or for space exploration?

Re: The emerging space technology
I liked the way how microsatellites are developing and how they partially substitute ordinary sats. This is a cheaper and easier way for some missions ordinary sats used to do. Also, we may use microsats bigger number of fields that only emphasis their competence. Satellite technology take part in our everyday lives, so we cannot imagine our present world without sat technology

Cheaper robust microchips. You can't build cheap microsatellites when (radiation-tolerant) chips are ridiculously expensive or, worse, out of stock. https://spacenews.com/satellite-makers- ... shortages/

Re: The emerging space technology
Getting back to my last message about satellite technology. Satellite technology evolved so, that we cannot imagine our everyday life without it I`d like to mention satellite technology that can track rare species of animals in order to prevent them from being killed by poachers.

The current chip shortage will not last forever and it affects everyone. I've been trying to get a GPU for my gaming PC since Christmas.
I wonder if cheap cube sats in low earth orbit actually use or need radiation hardened microprocessors.

Some use them, some don't. Depends on the required reliability, cost and lifetime of the cubesats. The ISIS IOBC, for example, uses mostly standard components (with some extra quality control) but adds a few radiation hardened chips to prevent complete failure in the case of a radiation-induced single event effect. Some cubesats use redundant COTS chips as a cheap solution. Often, it's a mix of both - redundancy wherever possible and radiation-hardened parts where redundancy is unfeasible.
Currently, radiation testing is expensive and time-consuming. That's unlikely to change. Analysis and simulation methods may improve, however.

Re: The emerging space technology
I see the revolution in space technology as having just happened (SpaceX reusability). Now it's about finding more uses for space now that space is easier/cheaper to get to. I don't foresee another revolution for a while ... just faster/cheaper/better in a gradual way using extensions of our existing tech.

Yeah, I`ve heard that Space X is gonna make Starlink satellites will be able to lead themself in the atmosphere of Earth when their lifespan is over to burn down there and not to increase the number of space junk
