Let's see if it wakes up once the sun hits the solar panels. Hopefully the thermal conditions do not kill it by then.

The main difficulty for this kind of tug is finding the market. There is currently only a very limited market for such missions:

1. If the customer is big enough, then the rocket itself can do the injection. Otherwise, you can try to find another customer on the same orbit
2. If it is a geo satellite, then it will have electric propulsion and adding a separate stage is hard to justify just by shortened transfer time
3. If you are planning on reusing the same tug for multiple missions, you are fighting the rocket equation. This thruster here makes it really hard, you need more efficiency.

The market fit is quite difficult, and this requires high investment. So very hard problem until we have an actual space economy with people on the moon.

I, too, have children at home.

Pour une voiture, cet effet est de l'ordre de microgrammes, donc somme toute négligeable par rapport à tout ce qui peut se passer autrement.

A noter qu'il y a aussi des types de batteries qui ont leur masse qui varie en fonction du taux de charge, car fonctionnant en système ouvert. Typiquement les batteries métal-air sont comme ça : tu fait rouiller pu dérouiller un métal avec l'oxygène de l'air.

En même temps, maintenant tu parles de ça au lieu de parler de la loi. Il a réussi son coup.

It means that U.S. automakers find it cheaper to have their vehicles made in China and then import them in the U.S., rather than make them directly in the U.S. in the first place.

This means that manufacturing in China is so cheap that even with the tariffs, it is more cost effective to go there. If your goal with the tariffs is to level the game, then this should not happen (no one would relocate like that unless there is a massive gain).

This.

I don't mind if they use the average household number in the title or header, that's understandable. But such an article should have the actual values somewhere.

Can we? Yes. Should we do it right now? That's debatable.

The question is how much this would cost vs getting a two weeks offline every 26 months?

These two weeks do not create any additional requirements (you already have to make sure the probes can survive for a few weeks without comms), science does not fully stops during these two weeks. And it gives an opportunity to do long duration maintenance on the ground segment.

Frankly, there is little need to spend >$100M for such relays satellites until we actually have a permanent human presence on Mars.

As heating network, they are and will be regulated like other energy suppliers: https://www.gov.uk/government/publications/energy-security-bill-factsheets/energy-security-bill-factsheet-heat-networks-regulation-and-zoning

That will be a nice explanation when they arrive in prison.
