Russia, China consider building joint on-orbit assembling space telescope

Russian and Chinese experts have developed a joint concept of what can become the world's first large telescope to be assembled in space by supervised robotic manipulators, Mikhail Sachkov, the deputy director of the Institute of Astronomy at the Russian Academy of Sciences which develops the project on the Russian end, said.

"Our Chinese colleagues have asked our institute to become the scientific organization of the telescope which they are going to promote. They wanted us to provide a complete scientific grounding of the project and relevant equipment. That is to say, they make the telescope and Russia makes the optical spectrometer," Sachkov said.

The 33-feet On-orbit Assembling Space Telescope (OAST) is what his institute and the Changchun Institute of Optics, Fine Mechanics and Physics are aiming to develop to match the US-developed James Webb Space Telescope, designed to replace Hubble Space Telescope.

According to the scientist, the project presently is not included in neither of the countries' space programs and, consequently, gets no state funding and is developed on a voluntary basis. He added that the telescope can be completed in the 2030s.

Last year, Sachkov said that Russia was planning to significantly reduce funding for its own Hubble-like Spektr-UV project, developed jointly with Germany and Spain and known also as the World Space Observatory-Ultraviolet (WSO-UV).

Unlike its predecessor, the Earth-orbiting Hubble telescope, the US' Webb observatory will orbit the Sun about a million miles from the Earth. As a result, Webb is expected to discover and collect data on thousands of exoplanets that orbit distant stars.

Simulated image demonstrates the power of NASA's WFIRST
Baltimore MD (SPX) Jan 06, 2020
Imagine a fleet of 100 Hubble Space Telescopes, deployed in a strategic space-invader-shaped array a million miles from Earth, scanning the universe at warp speed. With NASA's Wide Field Infrared Survey Telescope, scheduled for launch in the mid-2020s, this vision will (effectively) become reality. WFIRST will capture the equivalent of 100 high-resolution Hubble images in a single shot, imaging large areas of the sky 1,000 times faster than Hubble. In several months, WFIRST could survey as m ... read more
