Included in the study was NASA's SPHEREx space telescope, the European Space Agency's proposed ARRAKIHS system, and China's planned Xuntian space telescope, as well as Hubble, all of which orbit at altitudes between about 450 and 800 kilometers. The findings suggest about 39.6 percent of Hubble's images and 96 percent of images from the other three telescopes would be affected by interference from satellites.

After putting 200 satellites into orbit in 2023, it has now doubled its orbital payloads from last year, and it is also building two substantial low-Earth-orbit constellations similar in some ways to Elon Musk's Starlink. These are just a few examples of howChina is speeding through its five-year national strategy for space. Launch vehicles have been expanded, satellites are continually being updated, and launch pads are being built for not just more but also faster missions. It has even tested experimental "dogfighting" satellites.
