Lunar lander in the context of "Chang'e 6"

The Apollo Lunar Module (LM /ˈlɛm/), originally designated the Lunar Excursion Module (LEM), was the lunar lander spacecraft that was flown between lunar orbit and the Moon's surface during the United States' Apollo program. It was the first crewed spacecraft to operate exclusively in space, and remains the only crewed vehicle to land anywhere beyond Earth.

Structurally and aerodynamically incapable of flight through Earth's atmosphere, the two-stage Lunar Module was ferried to lunar orbit attached to the Apollo command and service module (CSM), about twice its mass. Its crew of two flew the Lunar Module from lunar orbit to the Moon's surface. During takeoff, the spent descent stage was used as a launch pad for the ascent stage which then flew back to the command module, after which it was also discarded.

Lunar Module Eagle (LM-5) is the spacecraft that served as the crewed lunar lander of Apollo 11, which was the first mission to land humans on the Moon. It was named after the bald eagle, which was featured prominently on the mission insignia. It flew from Earth to lunar orbit on the command module Columbia, and then was flown to the Moon on July 20, 1969, by astronaut Neil Armstrong with navigational assistance from Buzz Aldrin. Eagle's landing created Tranquility Base, named by Armstrong and Aldrin and first announced upon the module's touchdown.

The name of the craft gave rise to the phrase "The Eagle has landed", the words Armstrong said upon Eagle's touchdown.

Chang'e 4 (/tʃɑːŋˈə/; Chinese: 嫦娥四号; pinyin: Cháng'é Sìhào; lit. 'Chang'e No. 4') is a robotic spacecraft mission in the Chinese Lunar Exploration Program of the CNSA. It made a soft landing on the far side of the Moon, the first spacecraft to do so, on 3 January 2019.

A communication relay satellite, Queqiao, was first launched to a halo orbit near the Earth–Moon L₂ point in May 2018. The robotic lander and Yutu-2 (Chinese: 玉兔二号; pinyin: Yùtù Èrhào; lit. 'Jade Rabbit No. 2') rover were launched on 7 December 2018 and entered lunar orbit on 12 December 2018, before landing on the Moon's far side. On 15 January it was announced that seeds had sprouted in the lunar lander's biological experiment, the first plants to sprout on the Moon. The mission is the follow-up to Chang'e 3, the first Chinese landing on the Moon.

An image dissector, also called a dissector tube, is a video camera tube in which photocathode emissions create an "electron image" which is then swept up, down and across an anode to produce an electrical signal representing the visual image. It employs magnetic fields to keep the electron image in focus, and later models used electron multiplier to pick up the electrons. The term had also been used for other kinds of early video camera tubes. Dissectors were used only briefly for research in television systems before being replaced by different much more sensitive tubes based on the charge-storage phenomenon like the iconoscope during the 1930s. Despite the camera tubes based on the idea of image dissector technology falling quickly and completely out of use in the field of Television broadcasting, they continued to be used for imaging in early weather satellites and the Lunar lander, and for star attitude tracking in the Space Shuttle and the International Space Station.
