Chandra X-ray Observatory

Chandra X-ray Observatory — space telescope, explore its interactive 3D model in Cosmoscope.

Track the Chandra X-ray Observatory around a 3D Earth. Explore its calculated live position, orbit and NASA 3D model using CelesTrak data.

NASA’s flagship X-ray telescope rides a long, looping orbit a third of the way to the Moon, seeing the hottest, most violent places in the Universe — exploded stars, colliding galaxy clusters and matter swirling into black holes.

The position of the Chandra X-ray Observatory is calculated continuously from CelesTrak orbital elements using SGP4. It is a propagated orbit, not a direct spacecraft telemetry feed; accuracy depends on the age of the source data.
