Introduction
Introduction

Space station -  spacecraft capable of supporting a crew which is designed to remain in for an extended period of time, and to which other spacecraft can dock. Space stations are used to study the effects of long-term space flight on the human body as well as to provide platforms for greater number and length of scientific studies than available on other space vehicles.


Objectives
Objectives

  • Build a model of a space station.

  • Try to build as sophisticated model as possible.

  • Pick suitable materials for model.

  • Find a way to connect all separate modules.

  • Extend our knowledge in subject matter.

Briefly about space station
Briefly about „Мир“ space station

„Мир“ was manned space station, designed for long-term research outpost in space.It had been visited by 104 different people from twelve different nations. When complete, the station consisted of seven pressurized modules: Мир core module, docking module, „Priroda“, „Spektr“, „Kristall“, „Kvant“ and „Kvant-2“


Orbit control
Orbit control

Мир was maintained in a near circular orbit with an average perigee of 354 km and an average apogee of 374 km, travelling at an average speed of 27,700 km/h and completing 15.7 orbits per day.  

As the station constantly lost altitude because of a slight atmospheric drag, it needed to be boosted to a higher altitude several times each year. This boost was generally performed by Progress resupply vessels or the engines on the core module.

The attitude (orientation) of the station was independently determined by a set of externally mounted sun, star and horizon sensors.


Additional info
Additional info

Energy:

Photovoltaic (PV) arrays powered Mir. The station used a 28 volt DC supply which provided 5-, 10-, 20- and 50-amp taps. When the station was illuminated by sunlight, several solar arrays mounted on the pressurized modules provided power to Mir's systems and charged the nickel-cadmium storage batteries installed throughout the station.

Stations records:

  • ValeriPolyakov holds record for the longest single human spaceflight, at 437 days 18 hours. 

  • Shannon Lucid held the record for longest stay in space by a woman, while aboard Мир —188 days.

Briefly about the station
Briefly about the station

  • This space station would be used for scientific research or military applications. Also, station could perform satellite functions because of its dishes, when it’s empty.

Used materials for model

  • Materials:

    Plastic sheets from old plastic box, wood sticks, broken Christmas decorations, LEDs from defected Christmas tree lights, some wires and one AA battery.


Energy
Energy

  • The main idea of the station is, that four solar panels makes enough power to run all electric parts in the station, which sends and receives information with antennas from the earth.

Propulsion equipment
Propulsion & equipment

  • Propulsion:

    Thisstation would use solar wind energy. It would catch solar wind particles using enormous metallic parachute. This kind of propulsion could be used for long-distance flights.

  • Equipment:

    Stations solar arrays, mounted in front, would provide energy. Station would have crew quarters and greenhouse. Greenhouse would provide crew with food and oxygen.


Gained knowledge
Gained knowledge

  • We found out, that space stations are used for various scientific research, also, that they can be artificial satellites. Also we learned many stations purpose, structure, executed missions. Also that space stations might be used for military and civil applications. Also we got to know various propulsion systems, history of space exploration and most important figures in space exploration.


Manned space stations
Manned space stations

  • "Skylab" — first NASA space station, servised 1973—1979 m. Here worked three groups of astronauts, each one of them consisting of three persons. Last crew been in station for 84 days.

  • „Saliut“— USSR manned space station series, which was exploited 1971—1982 m. All stations were lifted with „Proton“ rockets. In all there were 7 stations. Crews consisted of 2-3 persons.

  • „Mir“ — USSR, later Russia space station, launched in 1986 m. „Mir“ was improved orbital stations „Saliut-7“ variant.

  • ISS — USA, West Europe, Japan and Russia orbital station, which was started to assemble in Earths orbit in 1998.
