WASHINGTON: The James Webb Space Telescope has fired its thrusters and reached its orbital destination around 1.5 million km away from our planet, NASA said Monday , a key milestone on its mission to study cosmic history.
For the giant parasol to offer effective protection, it needs the Sun, Earth and Moon to all be in the same direction, with the cold side operating at -225 Celsius. It was therefore decided to slightly underburn the rocket firing and use the telescope's own thrusters to make up the difference. Webb won't sit precisely at L2, but rather go around it in a"halo" at a distance similar to the Earth and Moon, completing a cycle every six months.
Webb's position will also allow continuous communications with Earth via the Deep Space Network -- three large antennas in Australia, Spain and California.
