WHAT IS INTERNATIONAL SPACE STATION (ISS)?
INTERNATIONAL SPACE STATION (ISS) is a permanently inhabited, government & industry-financed space station made by the US in partnership with some other countries which includes: UK, France, Belgium, Italy, Netherlands, Denmark, Norway, Spain, Switzerland, Sweden, West Germany, Canada, and Japan and some others.
It is a carefully constructed structure that contains a vast array of interconnected airlocks, docking ports, and pressurized modules. It houses the astronauts who live and work in space, consider the International Space Station (ISS) as an earthly house that accommodates a large number of individuals however, in the case of the International Space Station (ISS) there are more live support structures than just a space for human accommodation.
Considering the condition of the space, the station is equipped with vast modules to enable the survival of inhabitants and the sustainability of the station easier as well as the control and navigation means of the station.
The International Space Station (ISS) contains the following components:
The small modules connect the larger modules together which permits the astronauts to move around the station as well as transport equipment within the space station.
This is a component that makes it easy for space vehicles to attach themselves to the ISS.
These are spaceships that carry astronauts to and from the earth as well as make a supply from the earth to the ISS.
There are pressurized modules that help to provide breathable air and help to warm the environment for the living quarters. They also provide the needed temperature and air to the laboratories, equipment room, as well as areas that crews work and live.
Integrated Truss Structure
This is the solar panels anchoring points’ structure, a housing section for the panels. It is a linear girder framework located on the top of pressurized modules. The structure also houses the radiators that help control the station’s temperature as well as the mobile base system’s rail lines.
Mobile Base System
The mobile Base system has a robotic arm that hauls cargo and experiment equipment. It is a traveling work platform that runs along the truss structure rails.
External Research and Payload Accommodations
This component provides multiple mounting locations at the outside of the ISS. It helps to house experiments that cannot be carried out inside the ISS.
The key function of the International Space Station (ISS) is to serve as an orbiting laboratory. It helps to carry out deep research on the space environment and its effects on materials that will lead to the development of better spaceships, satellites, and space stations.
The continuous experiment will help in future engineering to build better communication systems and advanced life-support systems for future spacecraft.
The International Space Station (ISS)is really a large structure that has almost the length of a football stadium according to Craig and Mark’s post on howstuffworks.com. Based on NASA’s record, the International Space Station (ISS) measures roughly 925,335 pounds (419,725kilograms). It has 388 cubic meters (13,696 cubic feet) of habitable space aboard and the size increases anytime another vessel is attached.
The primary electric power in the International Space Station (ISS) comes from the array of solar panels which measures about 240ft long and form a total area coverage of 27,000square feet.
The array of solar panels form a grid and it is anchored to the station. They generate roughly 84kilowatts to 120kilowatts of electricity at the quantity that is enough to power 40 homes.
The solar panels help to store sixty percent of the energy generated from the sun in the lithium-ion batteries meant for power storage.
LOCATION AND NAVIGATION
The orbiting altitude of the International Space Station (ISS) needs to be maintained because the earth’s atmosphere is extremely thin but thick enough to drag the station down. To keep it at its altitude at all times, the International Space Station (ISS) must be boosted frequently so that it does not veer off-course and start decelerating.
One of the modules known as Zvezda made by Russia has an engine that can be used to boost the International Space Station (ISS) though most of the rebooting are carried out by the progress supply ships. The ships require rocket engine burns to be able to move the ISS.
The navigation ability of the International Space Station (ISS) helps it to locate other space objects by moving from one point to another.
There is a need for steady and reliable communication with the control center on Earth. As a result, the International Space Station (ISS) crew use Tracking and Data Relay Satellites (TDRS) positioned about 35,400 kilometers (22,000 miles) above the earth. The signals having video, voice, and scientific data are relayed through these devices to fasten the communication between International Space Station (ISS)crews and the control center (NASA) located in Houston.
LIVING IN SPACE
There are lots of technologies put in place to help sustain life in the International Space Station (ISS) despite the unfavorable weather conditions and other unfavorable conditions.
The station life support system keeps the temperature suitable for the areas occupied by the crews despite having the lowest cold temperature of around -128 degrees Celsius and the hottest temperature of about 60 degrees Celsius. The systems use stored heat and other methods to keep the inside warm and stable as the statin pass through the cold and hot routes as it rotates along with the earth’s attitude.
The crew in space also have some possible health challenges which the life support system helps to counter.
The presence of microgravity in space is one of the challenges of working in space. Besides creating inconveniences on getting things to be in their place, the absence of gravity depreciates the calcium in the body and could lead to bone size reduction. To counter this challenge, astronauts spend about 2.5hours daily doing exercise.
