MW 18014 was a German A-4 test rocket [nb 1] launched on 20 June 1944, [1] [2] [3] at the Peenemünde Army Research Center in Peenemünde.It was the first human-made object to reach outer space, attaining an apogee of 176 kilometres (109 mi), well above the Kármán line that was established later as the lowest altitude of space.

The term artificial objects is closely associated with made by humans or not naturally occurring items that have been sent into space.

But some artificial objects which are covered in green may have a blue color. [2] This phenomenon is due to the fact that plants reflect more infrared radiation (IR) than man-made objects. [2] Dense vegetation cover may give a more intense red color than that of sparse vegetation cover. This helps in determining whether the trees are healthy or ...
Pioneer 10 – launched in 1972, flew past Jupiter in 1973 and is heading in the direction of Aldebaran (65 light years away) in the constellation of Taurus.Contact was lost in January 2003, and it is estimated to have passed 134 astronomical units (AU; one AU is roughly the average distance between Earth and the Sun: 150 million kilometers (93 million miles)).
The militarisation of space involves the placement and development of weaponry and military technology in outer space. The early exploration of space in the mid-20th century had, in part, a military motivation, as the United States and the Soviet Union used it as an opportunity to demonstrate ballistic-missile technology and other technologies ...
Vanguard 1. Expected to de-orbit in ~2240AD, this and its upper launch stage are the oldest human-made objects in space. Also the first use of solar cells to power a satellite.

The telescope is part of the Maui Space Surveillance Complex (MSSC), which in turn is part of the Air Force Maui Optical and Supercomputing Site (AMOS). The 3.67-meter telescope, known as the Advanced Electro-Optical System (AEOS), owned by the Department of Defense, is the United States' largest optical telescope designed for tracking satellites.
Green, 515/520–590/600 nm, is used for imaging vegetation and deep water structures, up to 90 feet (30 m) in clear water. Red, 600/630–680/690 nm, is used for imaging man-made objects, in water up to 30 feet (9 m) deep, soil, and vegetation. Near infrared (NIR), 750–900 nm, is used primarily for imaging vegetation.
