The Progress is an expendable unmanned freighter spacecraft; it is Soyuz derived and is launched also by the Soyuz launch vehicle. It is currently used for supplies to the International Space Station, in addition to what the two manned Soyuz flights per year can carry. There are three to four flights per year. Each spacecraft remains docked until shortly before the new one arrives, and is then disconnected, deorbited and destroyed in the atmosphere.

It has launched fuel and other supplies to all the space stations since Salyut 6. The idea of the Progress came from the realisation that for long duration space missions to be possible there would have to be constant resupply of stations. It had been decided that a cosmonaut needed 30 kg of consumables a day. This equates to 5.4 tonnes over a 6 month stay. It was impossible to launch all this with the station or to bring up new supplies in the small space available in the Soyuz.

Progress is of much the same size and shape as Soyuz. It consists of three modules:

A pressurised forward module. This contained the supplies for the crew such as food, scientific equipment, clothes, prepackaged and fresh food, and letters from home. The docking drogue is similar to that of the Soyuz but featured ducting for the UDMH fuel and N₂O₂ oxidiser.
The reentry module was replaced with a unpressurized propellant and refueling compartment with ducting along the outside of the spacecraft. This meant that if a leak occurred the poisonous gas would not enter the stations atmosphere. The fuel was carried in two tanks.
The propulsion module at the rear was unchanged and contained the orientation engines used for the automatic docking.

Weight savings were accomplished by the fact the Progress was designed to be unmanned and unreturnable. This meant that there was no need for bulky life support systems and heat shields. There was also no ability for the spacecraft to separate into separate modules. After undocking the spacecraft performed a retrofiring and burnt up harmlessly in the atmosphere.

The bureau in charge of designing the freighter was TsKBEM (now RKK Energia). They started designing in mid- 1973, giving the Progress the highly descriptive designation 11F615A15. The design was complete by February 1974 and the first production model was ready for launch November 1977. Progress 1 launched January 20, 1978 aboard the same rocket used to launch the Soyuz. It still featured the same launch shroud as the Soyuz, though this was for aerodynamic purposes as the launch escape system had been deactivated.

This first version of Progress had a mass of 7,020 kg and took 2,300 kg of cargo or 30% of launch weight. It had the same diameter as the Soyuz at 2.2 metres but was 8 metres in length—a little longer. The autonomous flight time was 3 days, the same time as that of the Soyuz ferry. It could spend one month docked. Progress also always docked to the aft port of the station it was resupplying.

This version of the Progress was used right up until 19861986 is a common year starting on Wednesday.

January 9 After losing a pa when it was replaced with the Progress M. This was basically the same as the original Progress but featured improvements from the Soyuz T and Soyuz TM . It could spend up to 30 days in autonomous flight and could carry 100 kg more to MirThis article is about Mir the Soviet space station. See Mir (disambiguation) for other meanings. Mir (, which can mean both world and peace in Russian) was a Soviet (and later Russian) space station. It was humanity's first permanently inhabited space sta. Also for the first time it could return items to Earth. This was accomplished by using the RadugaThe VBK-Raduga capsule is a reentry capsule that was used for returning materials to Earth's surface from the space station Mir. They were brought to Mir in the Progress-M cargo craft's dry cargo compartment. For return, the capsule would be substituted f capsule. This could carry items of up to 150 kg back to Earth. It was 1.5 m long and 60 cm in diameter and had a dry weight of 350 kg. For the first time Progress could dock to the forward port of the stations and still transfer fuel. It also used the same rendezvous system as the Soyuz and featured solar panels for the first time.

This spacecraft is still used today for the International Space Station. It is currently the only spacecraftA spacecraft is a vehicle that travels through space. Spacecraft include robotic or unmanned space probes as well as manned vehicles. The term is sometimes also used to describe artificial satellites, which have similar design criteria. The term spaceship available for transporting large quantities of supplies to the station with the Space Shuttle grounded after the breakup of Columbia at the end of STS-107Mission Insignia Mission Statistics Mission:STS-107 Shuttle: Columbia Launch Pad: 39A Launch: January 16, 20039:39 a.

For ISS missions, the Progress M1 variant is used, which moves the water tanks from the propellant and refueling module to the pressurized section and can carry more propellant.

The ESAThis article is about the European Space Agency. See Entertainment Software Association for another meaning of ESA. The European Space Agency ESA is an inter-governmental organisation dedicated to exploration of space and its exploitation. Its headquarter are planning their own supply freighter called the Automatic Transfer Vehicle. The first of these, Jules Verne, is due for launch in the second half of 2005. It will be able to carry up to 7.5 tonnes of cargo into space and will be launched every 12 months by an Ariane 5 rocket.
