Space Station 101

While most spacecraft carry human passengers from earth to a specific spot in space or back, the space station is mostly designed to serve as a dock for other spacecraft. Currently, there are two space stations in space. One is the Tiangong-1 of China which is seldom manned and the other is the ISS or the International Space Station which is always manned. Here are some important things that you need to know aboutspace stations:

Purpose. Space stations are created and placed in space for research purposes. Mainly, these studies are about the space flight effects on humans. It is also used for studies concerning different kinds of space vehicles and their performances.
Short-term Stay. Some humans may stay in a space station for days or even weeks in some cases but staying in one for months or a year will pose health risks as well as discomfort. It emits radiation that will most likely harm inhabitants who stay in the space station.
Components. A space station usually contains most if not all of the following: structure, thermal control, orbital navigation, orbital propulsion, computing, communications, crew facilities, electrical power, attitude control, attitude determination, automation, robotics, environmental support, life support, crew transportation, and cargo transportation. These components are the subsystem of a space station.
Popular Space Stations. Some of the popular space stations are Salyut, Mir, Tiangong, Skylab, and the ISS.
Molds Situation. In a space station, a kind of mold grows which is capable of degrading different elements such as metal, rubber, and glass.
The Future of Space Stations

Future plans for spacestations include the following:

Microgravity research capability
Commercial spaceflight destination
Space tourism
Product development capability
Service and Maintenance for satellites
Orbital Space Club
Lunar landing mission support
