With burst of 100 tons at a time I’d think it’d be more, but if it’s only every 2.4(?) rotation and mostly only during the short “Summer”, I suppose that it can add up.

China has now begun operating the world’s largest radio telescope! The 500 meter aperture spherical telescope, compared to 53 years old “tiny” Arecibo’s 305 meters. And with other advantages in terms of reflectivity and sky coverage and whatnot. I think it is especially good news that the Chinese are doing good things, science for science sake, like their ambitious interplanetary space program recently announced. I suppose it works as a radar too and can characterize near Earth objects. Arecibo even maps volatilities in Mercury’s polar craters with radar. But as usual info from China is not very easy to find online so I’m not sure about FAST using radar.
