StriX satellites use synthetic aperture radar, which bounces radio pulses off the ground to build images and can see through clouds and at night. Each satellite weighs about 100 kg (220 pounds) and unfolds a radar antenna roughly 5 m (16 feet) wide once in orbit.

Home made? Wow how come when I do that I get arrested

Have you tried being a billionaire villain? That usually helps.

You usually need to apply for a launch licence before launching your rocket. Perhaps you forgot that step?

In the case of this article, "home-built" seems to mean "domestic", as in originating from the same country. I don't think the folks over at Mitsubishi Heavy Industries are actually building the rockets in their back garden or shed.

The problem is building it, rocket fuel for example is illegal to make

rocket fuel for example is illegal

Depends on what kind of fuel and where you live. Many rockets are fuelled by kerosene or methane, which are not illegal in most places.

You're not making kerosene or methane lmao

Not sure what your whole argument is here, you can obtain those fuels without too much trouble and all you need to actually launch in a lot of places is apply for permission. How do you think commercial rocket launches happen?

You’re not making methane lmao
