The Shuttle–Mir program (Russian: Программа «Мир»–«Шаттл») was a collaborative space program between Russia and the United States that involved American Space Shuttles visiting the Russian space stationMir, Russian cosmonauts flying on the Shuttle, and an American astronaut flying aboard a Soyuz spacecraft to allow American astronauts to engage in long-duration expeditions aboard Mir.
The project, sometimes called "Phase One", was intended to allow the United States to learn from Russian experience with long-duration spaceflight and to foster a spirit of cooperation between the two nations and their space agencies, the National Aeronautics and Space Administration (NASA) and the Russian Space Agency (PKA). The project helped to prepare the way for further cooperative space ventures; specifically, "Phase Two" of the joint project, the construction of the International Space Station (ISS). The program was announced in 1993, the first mission started in 1994 and the project continued until its scheduled completion in 1998. Eleven Space Shuttle missions, a joint Soyuz flight and almost 1,000 cumulative days in space for American astronauts occurred over the course of seven long-duration expeditions. In addition to Space Shuttle launches to Mir the United States also fully funded and equipped with scientific equipment the Spektr module (launched in 1995) and the Priroda module (launched in 1996), making them de facto U.S. modules during the duration of the Shuttle-Mir program.
During the four-year program, many firsts in spaceflight were achieved by the two nations, including the first American astronaut to launch aboard a Soyuz spacecraft, the largest spacecraft ever to have been assembled at that time in history, and the first American spacewalk using a Russian Orlan spacesuit.
Wernher von Braun (1912–1977) was a German rocket scientist and one of the most important rocket developers and champions of space exploration during the period between the 1930s and the 1970s. Von Braun is well known as the leader of what has been called the “rocket team” which developed the V-2 ballistic missile for the Nazis during World War II. As part of a military operation called Project Paperclip, he and his rocket team were scooped up from defeated Germany and sent to America where they were installed at Fort Bliss, Texas. For fifteen years after World War II, von Braun worked with the U.S. Army in the development of ballistic missiles. At Fort Bliss, they worked on rockets for the U.S. Army, launching them at White Sands Proving Ground, New Mexico. In 1950 von Braun’s team moved to the Redstone Arsenal near Huntsville, Alabama, where they built the Army’s Jupiter ballistic missile. In 1960, his rocket development center transferred from the Army to the newly established NASA and received a mandate to build the giant Saturn rockets. Accordingly, von Braun became director of NASA’s Marshall Space Flight Center and the chief architect of the Saturn V launch vehicle, the superbooster that would propel Americans to the Moon.
A transit of Earth by the Moon, as photographed by the Deep Space Climate Observatory from the Sun-Earth L1Lagrangian point. This animation was compiled from a set of 60 frames—20 distinct images, each compiled from monochrome images taken in red, green and blue filters—taken over the course of five hours on July 16, 2015. Each monochrome frame was taken every 30 seconds. Due to the speed of the Moon's motion, this results in a slight green shift in some frames of the animation.
