Chinese spacecraft Queqiao designed to relay signals of the lunar probe Chang’e-4, was sent to Earth pictures of the planet and back side of the moon.
Queqiao is on a halo orbit around the Lagrange point L2 of the system Earth-Moon, at a distance of about 65-80 thousand kilometers from the moon’s surface and is equipped with a 4.2-meter parabolic antenna.
On Board the satellite in addition to radio, installed tool NCFE (Netherlands-China Low-Frequency Explorer), that searches for low-frequency radio emission from the early Universe and a laser rangefinder to determine the distance to the moon.
Optical cameras mounted on Board the spacecraft, were able to get a few images that were subsequently downlinked to the Ground. They are visible to the Earth and back side of the moon, covered with craters and dark spots lunar lakes and seas, in addition to one of the shots hit the antenna of the tool NCFE.
