Telescope’s ‘retina’ undergoes final test
Scientists carried out the last step in testing a key component of China’s gigantic radio telescope on Nov 21. After its scheduled completion next September it will be the largest such telescope in the world.
A team successfully tested the installation of the telescope’s “retina”, a mechanism weighing 30 metric tons and suspended 140 to 160 meters above the half-finished reflector dish, which will collect signals from the universe.
The telescope, 500 meters in diameter, is composed of 4,500 mostly triangular panels with sides measuring 11 meters that create a parabolic shape or hemisphere. The motion of the panels alters the collective shape of the antenna, which is capable of reflecting radio signals from the universe to a focal point, where the receiver dome sits.

The drone maker DJI Technology Co says it has changed its flight systems to ensure its drones keep out of restricted areas, such as over Tian’anmen Square in Beijing and the White House in Washington.
DJI of Shenzhen, which claims 70 percent of the world’s drone market, said its Geospatial Environment Online system will provide DJI drone users with up-to-date guidance on locations where flights may be restricted by regulation. It can also raise safety concerns.
The new system will allow users who have verified DJI accounts to temporarily unlock or selfauthorize flights in some of those locations “to accommodate the vast variety of authorized applications”.
The system will be launched first in North America and Europe, while other regions will continue to use a no-fly zone geo-fencing system the company introduced more than a year ago.
