Microwave and infrared are absorbed by the water in Earth’s atmosphere, so, if you can find a location above most of the moisture and away from clouds, you can conduct some of those observations. X-rays and gamma rays, however, are absorbed by the ozone layer, which is much, much higher in the atmosphere, and the only way to get above it is to go into orbit. Why astronomers want to observe the same object in multiple wavelengths? Different wavelengths provide different information about different processes.
