Animation of TESS's two phases while in orbit. During HASO--or high-altitude science operations--the spacecraft is farther from Earth and is capturing science data with its cameras. As it nears its closest approach to Earth, it switches to LAHO--low-altitude housekeeping operations--and rotates to transmit and recieve data from the ground.
This animation illustrates the Kepler-186 system, whose fifth world is the first Earth-sized exoplanet to be found orbiting within its star’s habitable zone. The animation closes with a simulated image from a coronagraph showing how such a planet might appear when directly imaged.
