The ISS maintains an orbit with an average altitude of 400 kilometres (250 mi) and circles the Earth in roughly 93 minutes, completing 15.5 orbits per day. The ISS programme combines two prior plans to construct crewed Earth-orbiting stations: Space Station Freedom planned by the United States, and the Mir-2 station, planned by
6216-519: The station with Ku band communications, additional attitude control needed for the additional mass of the USOS, and additional solar arrays. Over the next two years, the station continued to expand. A Soyuz-U rocket delivered the Pirs docking compartment . The Space Shuttles Discovery , Atlantis , and Endeavour delivered the American Destiny laboratory and Quest airlock , in addition to
6300-539: The station's main robot arm, the Canadarm2 , and several more segments of the Integrated Truss Structure. Tragedy struck in 2003 with the loss of the Space Shuttle Columbia , which grounded the rest of the Shuttle fleet, halting construction of the ISS. Assembly resumed in 2006 with the arrival of STS-115 with Atlantis , which delivered the station's second set of solar arrays. Several more truss segments and
6384-454: The station, which was released on YouTube. It was the first music video filmed in space. In November 2017, while participating in Expedition 52 / 53 on the ISS, Paolo Nespoli made two recordings of his spoken voice (one in English and the other in his native Italian), for use on Misplaced Pages articles. These were the first content made in space specifically for Misplaced Pages. In November 2021,
6468-465: The station. The first crew, Expedition 1 , arrived that November aboard Soyuz TM-31 . The ISS grew steadily over the following years, with modules delivered by both Russian rockets and the Space Shuttle. Expedition 1 arrived midway between the Space Shuttle flights of missions STS-92 and STS-97 . These two flights each added segments of the station's Integrated Truss Structure , which provided
6552-452: The strap-on boosters. This scheme resembles flight conditions when the strap-on boosters push the central core forward. The concept of suspending the rocket was one of the novelties introduced with the R-7/Soyuz. Since the launch pad has been eliminated, the bottom portion of the rocket is lowered. The launch system trusses bear the wind loads. Resistance to high wind is an important feature of
6636-425: The support booms track the movement of the rocket. After the support boom heads emerge from the special support recess in the nose sections of the strapons, the support booms and trusses disconnect from the rocket airframe, swiveling on the support axes and freeing the way for the rocket to lift off. During launch, the rocket and the launch facility form a single dynamic system. When the strap-on booster engines stop,
6720-550: The uncrewed Soyuz-U launch of the Photon-M satellite from Plesetsk fell back near the launch pad and exploded 29 seconds after lift-off. One person from the ground crew was killed and eight were injured. Another failure occurred on 21 June 2005, during a Molniya military communications satellite launch from the Plesetsk launch site, which used a four-stage version of the rocket called Molniya-M . The flight ended six minutes after
6804-785: The universe. Examples of Earth-viewing remote sensing experiments that have flown on the ISS are the Orbiting Carbon Observatory 3 , ISS-RapidScat , ECOSTRESS , the Global Ecosystem Dynamics Investigation , and the Cloud Aerosol Transport System . ISS-based astronomy telescopes and experiments include SOLAR , the Neutron Star Interior Composition Explorer , the Calorimetric Electron Telescope ,
6888-572: Was launched while being enclosed in a ST fairing. The first stage of Soyuz rockets consists of four identical conical liquid booster rockets strapped to the second stage core. These boosters are also called Blok-B, V, G, and D . Each engine has four main combustion chambers and two vernier thruster combustion chambers for attitude control. The engine is pump-fed by a hydrogen peroxide gas generator. Propellant tanks are pressurized using liquid nitrogen vaporization. Statistics (each of 4 boosters): The Soyuz booster's second stage, also called Blok-A ,
6972-401: Was originally intended to be a laboratory, observatory, and factory while providing transportation, maintenance, and a low Earth orbit staging base for possible future missions to the Moon, Mars, and asteroids. However, not all of the uses envisioned in the initial memorandum of understanding between NASA and Roscosmos have been realised. In the 2010 United States National Space Policy ,
7056-534: Was the Skylab-Salyut Space Laboratory, which proposed docking the Skylab B to a Soviet Salyut space station. Falling budgets and rising Cold War tensions in the late 1970s saw these concepts fall by the wayside, along with another plan to have the Space Shuttle dock with a Salyut space station. In the early 1980s, NASA planned to launch a modular space station called Freedom as a counterpart to
