Life on Earth to be clearer from space
Print Edition
CHINESE researchers are confident of making technological breakthroughs over the next four years in developing high resolution imaging that can see car-sized objects on Earth from high orbit in space.
Researchers at the Changchun Institute of Optics, Fine Mechanics and Physics, who are receiving significant government support, are studying camera technologies suited for satellites 36,000 kilometers from Earth. The institute’s plan aims to achieve an optical resolution of 2.5 meters for the camera — equivalent of seeing a hair clearly from 800 meters.
The technologies will enable cameras to operate on satellites in high orbit, known as geostationary orbit, allowing the cameras to appear stationary in the sky and view the same point on Earth continuously.
China already has high-resolution imaging in space, but at a lower orbit of about several hundred kilometers from Earth. Low-orbiting satellites constantly move around Earth and can only take snapshots of the planet when in flight.
Changchun institute is confident of completing the research by the end of 2020, said its deputy head Zhang Xuejun.
