It would work fine in a vacuum, e.g. on the moon. Unfortunately, on earth we have a thick atmosphere to deal with. Orbits are about going sideways VERY fast. If you try and plough through the atmosphere at 7km/second it creates a LOT of heat, and uses a LOT of energy. You also can’t just lob a satellite up. It will need to circularise its orbit, so you need to log an engine and fuel too.
Basically, it’s viable as a technological idea, but not on earth.
The atmosphere stops a lot of the high energy stuff. It gets absorbed, and turned into a shower of lower energy particles.
I remember reading once about an astronaut seeing blue flashes in their eyes. When they realised, they got behind the water tank sharpish. It was high energy particles passing through their eyeballs.
