It had a greater mass than any previous spacecraft. At the time it was the largest artificial satellite in orbit, succeeded by the International Space Station ISS after Mir 's orbit decayed. The station served as a microgravity research laboratory in which crews conducted experiments in biology , human biology , physics , astronomy , meteorology , and spacecraft systems with a goal of developing technologies required for permanent occupation of space.

Mir was the first continuously inhabited long-term research station in orbit and held the record for the longest continuous human presence in space at 3, days, until it was surpassed by the ISS on 23 October Mir was occupied for a total of twelve and a half years out of its fifteen-year lifespan, having the capacity to support a resident crew of three, or larger crews for short visits.

Following the success of the Salyut programme , Mir represented the next stage in the Soviet Union's space station programme. The first module of the station, known as the core module or base block, was launched in and followed by six further modules. Proton rockets were used to launch all of its components except for the docking module , which was installed by US Space Shuttle mission STS in When complete, the station consisted of seven pressurised modules and several unpressurised components.

Power was provided by several photovoltaic arrays attached directly to the modules. The station was launched as part of the Soviet Union's manned spaceflight programme effort to maintain a long-term research outpost in space, and following the collapse of the USSR, was operated by the new Russian Federal Space Agency RKA.

As a result, most of the station's occupants were Soviet; through international collaborations such as the Intercosmos, Euromir and Shuttle— Mir programmes, the station was made accessible to space travellers from several Asian, European and North American nations. Mir was deorbited in March after funding was cut off. Four Salyut space stations had been launched since , with three more being launched during Mir' s development.

It was planned that the station's core module DOS-7 and the backup DOS-8 would be equipped with a total of four docking ports; two at either end of the station as with the Salyut stations, and an additional two ports on either side of a docking sphere at the front of the station to enable further modules to expand the station's capabilities. By August , this had evolved to the final configuration of one aft port and five ports in a spherical compartment at the forward end of the station.

It was originally planned that the ports would connect to 7. These modules would have used a Soyuz propulsion module, as in Soyuz and Progress , and the descent and orbital modules would have been replaced with a long laboratory module.

The docking ports were reinforced to accommodate tonne short-ton space station modules based on the TKS spacecraft. KB Salyut began work in , and drawings were released in and New systems incorporated into the station included the Salyut 5B digital flight control computer and gyrodyne flywheels taken from Almaz , Kurs automatic rendezvous system , Luch satellite communications system, Elektron oxygen generators, and Vozdukh carbon dioxide scrubbers.

By early , work on Mir had halted while all resources were being put into the Buran programme in order to prepare the Buran spacecraft for flight testing. It was clear that the planned processing flow could not be followed and still meet the launch date. It was decided on Cosmonaut's Day 12 April to ship the flight model of the base block to the Baikonur cosmodrome and conduct the systems testing and integration there. The module arrived at the launch site on 6 May, with of cables requiring rework based on the results of tests to the ground test model at Khrunichev.

In October, the base block was rolled outside its cleanroom to carry out communications tests. The first launch attempt on 16 February was scrubbed when the spacecraft communications failed, but the second launch attempt, on 19 February at UTC, was successful, meeting the political deadline. The orbital assembly of Mir began on 19 February with the launch of the Proton-K rocket. Four of the six modules which were later added Kvant -2 in , Kristall in , Spektr in and Priroda in followed the same sequence to be added to the main Mir complex.

Firstly, the module would be launched independently on its own Proton-K and chase the station automatically. It would then dock to the forward docking port on the core module's docking node, then extend its Lyappa arm to mate with a fixture on the node's exterior.

The arm would then lift the module away from the forward docking port and rotate it on to the radial port where it was to mate, before lowering it to dock. The node was equipped with only two Konus drogues, which were required for dockings. This meant that, prior to the arrival of each new module, the node would have to be depressurised to allow spacewalking cosmonauts to manually relocate the drogue to the next port to be occupied. The other two expansion modules, Kvant -1 in and the docking module in , followed different procedures.

Kvant -1, having, unlike the four modules mentioned above, no engines of its own, was launched attached to a tug based on the TKS spacecraft which delivered the module to the aft end of the core module instead of the docking node. Once hard docking had been achieved, the tug undocked and deorbited itself. Atlantis then docked, via the module, to Kristall , then left the module behind when it undocked later in the mission.

The station's assembly marked the beginning of the third generation of space station design, being the first to consist of more than one primary spacecraft thus opening a new era in space architecture. First generation stations such as Salyut 1 and Skylab had monolithic designs, consisting of one module with no resupply capability; the second generation stations Salyut 6 and Salyut 7 comprised a monolithic station with two ports to allow consumables to be replenished by cargo spacecraft such as Progress.

The capability of Mir to be expanded with add-on modules meant that each could be designed with a specific purpose in mind for instance, the core module functioned largely as living quarters , thus eliminating the need to install all the station's equipment in one module. In its completed configuration, the space station consisted of seven different modules, each launched into orbit separately over a period of ten years by either Proton-K rockets or Space Shuttle Atlantis.

In addition to the pressurised modules, Mir featured several external components. The largest component was the Sofora girder, a large scaffolding-like structure consisting of 20 segments which, when assembled, projected 14 metres from its mount on Kvant A self-contained thruster block, the VDU, was mounted on the end of Sofora and was used to augment the roll-control thrusters on the core module.

This girder, a small prototype of a structure intended to be used on Mir -2 to hold large parabolic dishes away from the main station structure, was 5 metres long and used as a mounting point for externally mounted exposure experiments.

To assist in moving objects around the exterior of the station during EVAs , Mir featured two Strela cargo cranes mounted to the sides of the core module, used for moving spacewalking cosmonauts and parts.

The cranes consisted of telescopic poles assembled in sections which measured around 1. Each module was fitted with external components specific to the experiments that were carried out within that module, the most obvious being the Travers antenna mounted to Priroda.

This synthetic aperture radar consisted of a large dish-like framework mounted outside the module, with associated equipment within, used for Earth observations experiments, as was most of the other equipment on Priroda , including various radiometers and scan platforms.

This backpack was designed to assist cosmonauts in moving around the station and the planned Buran in a manner similar to the US Manned Maneuvering Unit , but it was only used once, during EO In addition to module-specific equipment, Kvant -2, Kristall , Spektr and Priroda were each equipped with one Lyappa arm , a robotic arm which, after the module had docked to the core module's forward port, grappled one of two fixtures positioned on the core module's docking node.

Photovoltaic PV arrays powered Mir. When the station was illuminated by sunlight, several solar arrays mounted on the pressurised modules provided power to Mir' s systems and charged the nickel-cadmium storage batteries installed throughout the station. The station itself also had to be oriented to ensure optimum illumination of the arrays.

When the station's all-sky sensor detected that Mir had entered Earth's shadow, the arrays were rotated to the optimum angle predicted for reacquiring the sun once the station passed out of the shadow. The solar arrays themselves were launched and installed over a period of eleven years, more slowly than originally planned, with the station continually suffering from a shortage of power as a result.

This relocation was begun in , when the panels were retracted and the left panel installed on Kvant By this time all the arrays had degraded and were supplying much less power. The first of these, the Mir cooperative solar array, consisted of American photovoltaic cells mounted on a Russian frame. This boost was generally performed by Progress resupply vessels, although during the Shuttle- Mir programme the task was performed by US Space Shuttles, and, prior to the arrival of Kvant-1 , the engines on the core module could also accomplish the task.

Radio links were also used during rendezvous and docking procedures and for audio and video communication between crew members, flight controllers and family members. As a result, Mir was equipped with several communication systems used for different purposes. The station communicated directly with the ground via the Lira antenna mounted to the core module. The Lira antenna also had the capability to use the Luch data relay satellite system which fell into disrepair in the s and the network of Soviet tracking ships deployed in various locations around the world which also became unavailable in the s.

While the constant free fall of the station offered a perceived sensation of weightlessness , the onboard environment was not one of weightlessness or zero gravity. The environment was often described as microgravity. This state of perceived weightlessness was not perfect, being disturbed by five separate effects: [23].

Mir 's environmental control and life support system ECLSS provided or controlled atmospheric pressure , fire detection, oxygen levels, waste management and water supply. The highest priority for the ECLSS was the station's atmosphere, but the system also collected, processed, and stored waste and water produced and used by the crew—a process that recycles fluid from the sink, toilet, and condensation from the air.

The Elektron system generated oxygen. Bottled oxygen and solid fuel oxygen generation SFOG canisters, a system known as Vika , provided backup. Carbon dioxide was removed from the air by the Vozdukh system.

Similar systems are presently used on the ISS. The atmosphere on Mir was similar to Earth's. Participation was also made available to governments of countries, such as France and India.

Only the last three of the programme's fourteen missions consisted of an expedition to Mir but none resulted in an extended stay in the station:. Various European astronauts visited Mir as part of several cooperative programmes: [29]. In the early s, NASA planned to launch a modular space station called Freedom as a counterpart to Mir , while the Soviets were planning to construct Mir -2 in the s as a replacement for the station.

The post-Soviet economic chaos in Russia also led to the cancellation of Mir -2, though only after its base block, DOS-8 , had been constructed.

Bush and Russian president Boris Yeltsin agreed to cooperate on space exploration. The project prepared the way for further cooperative space ventures, specifically, "Phase Two" of the joint project, the construction of the ISS. The programme was announced in ; the first mission started in , and the project continued until its scheduled completion in Eleven Space Shuttle missions, a joint Soyuz flight, and almost cumulative days in space for US astronauts occurred over the course of seven long-duration expeditions.

Inside, the tonne short-ton Mir resembled a cramped labyrinth , crowded with hoses, cables and scientific instruments—as well as articles of everyday life, such as photos, children's drawings, books and a guitar. It commonly housed three crew members, but was capable of supporting as many as six for up to a month. The station was designed to remain in orbit for around five years; it remained in orbit for fifteen.

The windows were covered during night hours to give the impression of darkness because the station experienced 16 sunrises and sunsets a day. A typical day for the crew began with a wake-up at , followed by two hours of personal hygiene and breakfast. Work was conducted from until , followed by an hour of exercise and an hour's lunch break.

Three more hours of work and another hour of exercise followed lunch, and the crews began preparing for their evening meal at about The cosmonauts were free to do as they wished in the evening, and largely worked to their own pace during the day.

In their spare time, crews were able to catch up with work, observe the Earth below, respond to letters, drawings and other items brought from Earth and give them an official stamp to show they had been aboard Mir , or make use of the station's ham radio. NASA astronaut Jerry Linenger related how life on board Mir was structured and lived according to the detailed itineraries provided by ground control.

Every second on board was accounted for and all activities were timetabled. After working some time on Mir , Linenger came to feel that the order in which his activities were allocated did not represent the most logical or efficient order possible for these activities.

He decided to perform his tasks in an order that he felt enabled him to work more efficiently, be less fatigued, and suffer less from stress. Linenger noted that his comrades on Mir did not "improvise" in this way, and as a medical doctor he observed the effects of stress on his comrades that he believed was the outcome of following an itinerary without making modifications to it.

Despite this, he commented that his comrades performed all their tasks in a supremely professional manner.

File photo of the International Space Station. Managers ordered the analysis after the space station program was extended five years from Engineers are also looking at the feasibility of another life extension until , the 30th anniversary of the launch of the outpost's first module.

There has been a lot of effort going into understanding that. We're just crossing T's and dotting the I's to make sure everything is documented. Right now, we're not projecting any controls on operations of station. The way this works is we do sort of generic enveloping analysis and see how the structure looks, and when we do that, we find some poke-outs.

Calling them "areas of interest" rather than problems, Suffredini said engineers are focusing on the zenith, or space-facing, port on the station's Unity module, the connecting adapter between Unity and the Russian Zarya module, and the interface between the outpost's truss backbone and the station's Destiny laboratory.

Russia is conducting its own review of its modules. The station's oldest piece, the Russian-built, U. The components flagged by the broad engineering analysis will receive closer scrutiny. File photo of the International Space Station's Zarya, Unity and Destiny modules, along with portions of the outpost's central truss. Dockings of visiting spacecraft, thermal cycles during each orbit of Earth, reboost maneuvers and crew exercise can affect the space station's structural health.

Without the ability to inspect the shell of the craft, like airplane engineers would do on Earth, NASA must use computer models to predict how cracks and deformities propagate in space. Launched in , the P6 truss segment and its foot solar arrays were mounted on another truss section on the Unity module's zenith port for nearly seven years, twice as long as designed.

The interim location subjected the structure to more extreme hot and cold temperatures than planned. Astronauts moved the P6 truss to a permanent location in Unity is located near the station's center-of-mass, putting additional stress on the module. It's been in a different thermal environment, and with more radiators deployed, but it's a rather robust structure.

It is an example of the vehicle's conservative design, which account for significant margins to ensure the station remains safe during many unforeseen events, according to Mulqueen.

Engineers say the retirement of the space shuttle is positive for the station's structure. Every docking of a ton shuttle orbiter shook the station, shaving life from its structure. Without the shuttle, station will use up less life in the next decade. Arrivals of smaller Russian, European, Japanese and commercial resupply and crew rotation missions do not have as big of an effect on the structure, Mulqueen said.

But the phase-out of the shuttle presents a challenge for managers trying to ensure there are enough spare parts aboard the space station to deal with breakdowns. Mulqueen believes there are enough spares aboard the complex through , and most spare parts needed through are already on the station. Another life extension beyond would likely require launches of more spares, Mulqueen said. We're working that right now with NASA, so future resupply is probably going to be a challenge.
