It is an approximately 120-percent-scale derivative of the Boeing X-40, [6] [22] measuring over 29 feet (8.8 m) in length, and features two angled tail fins. [26] [41] The X-37 launches atop an Atlas V 501 [26] [19] or a SpaceX Falcon 9 [42] or Falcon Heavy [43] rocket. The spaceplane is designed to operate in a speed range of up to Mach 25 on ...
Pituffik Space Base (/ b iː d uː ˈ f iː k / bee-doo-FEEK; [2] Greenlandic:; IATA: THU, ICAO: BGTL), formerly and perhaps better known as Thule Air Base (/ ˈ t uː l iː /), is a United States Space Force base located on the northwest coast of Greenland.
The Buran programme was started by the Soviet Union as a response to the United States Space Shuttle program [17] and benefited from extensive espionage undertaken by the KGB of the unclassified US Space Shuttle program, [18] resulting in many superficial and functional similarities between American and Soviet Shuttle designs.

Greenland ice sheet as seen from space. An ice sheet is a body of ice which covers a land area of continental size - meaning that it exceeds 50,000 km 2. [4] The currently existing two ice sheets in Greenland and Antarctica have a much greater area than this minimum definition, measuring at 1.7 million km 2 and 14 million km 2, respectively.
Full-scale model of the X-43 plane in Langley's 8-foot (2 m), high-temperature wind tunnel The craft was created to develop and test a supersonic-combustion ramjet, or " scramjet " engine, an engine variation where external combustion takes place within air that is flowing at supersonic speeds.

Annual ice losses from the Greenland ice sheet accelerated in the 2000s, reaching ~187 Gt/yr in 2000–2010, and an average mass loss during 2010–2018 of 286 Gt per year. Half of the ice sheet's observed net loss (3,902 gigatons (Gt) of ice between 1992 and 2018, or approximately 0.13% of its total mass [ 53 ] ) happened during those 8 years.
