Today I will be informing you on:
Canadian contributian to the ISS
Canada's contribution to the ISS is the mobile servicing system (MSS). The MSS is a sophisticated robotics suite that assembled the station in space, module by module. Developed for the Canadian Space Agency by MDA of:
-Canadarm2, a 17-metre long robotic arm
-Dextre, the stations two-armed robotic "handyman"
-The mobile base is a moveable work platform and storage facility
Canada's investment gives Canadian scientists access to the ISS to conduct research for the benefits of canadian's.
Canada's investment of money to ISS
According to a 2012 CSA audit, the total cost of Canada’s participation in the construction of the ISS was $1.245 billion as of March 31st 2003 for developing, designing and installing the MSS and about C$40 million in annual operating expenditures to maintain this participation.
Technological tools and devices for space exploration
These tools you will be familiar with since they are are also used on earth. However, any instrument used in space is specially made to endure harsh conditions.
The oldest instrument used in space exploration may be the telescope made in 1608 it is the most relied upon instrument of astronomers since the invention of the refracting telescope. It was Galileo who revolutionized space science with his insightful observations which he made using his modified refracting telescope.
Some types of telescopes used for space exploration are the optical telescope, radio telescope, infrared telescope, and ultraviolet telescope.
Another instrument used for space exploration are camera's.They are used to take high quality pictures of the surface and cosmic bodies. Both navigation and hazard camera's help controls stations on earth lead robots across the surface of the planets. Microscopic reflectors are specially designed to take pictures of soil and rocks with very high precision to forward the study of planetary geology.
Spectrometers are another scientific instrument which astronomers depend on greatly to learn more about the characteristics and composition of different cosmic bodies. Every space examination is adapted with spectrometers of different uses and capabilities. For example Mars exploration rovers, Spirit and Opportunity are armed with a Miniature Thermal Emission Spectrometer, Mössbauer spectrometer and Alpha Particle X-Ray Spectrometer, each with different purposes. The cameras and spectrometers of different capabilities and uses are used in all missions.
One of the greatest challenges of space exploration is the highly hostile environmental conditions, which make human exploration basically impossible in most cosmic environments. Scientists overcome this challenge by developing different types of space robots. There are several different types of space robots like flybys, rovers, robotic arms, humanoids and orbiters. The Canadian space arm and the futuristic Robonaut 2 are examples of robotic instruments used in outer space. Like the other instruments used in outer space, the use of mutifunction robots in space exploration is also gaining energy.
Exposure to shorten gravity causes muscle fibers to shrink causing astronauts to become weaker and less coordinated. The astronauts must contain strong for missions objectives and emergencies. It is important for astronauts to exercise. They exercise by using Cycle Ergo meters, treadmills, Advanced Resistive Exercise Devices (ARED) located in the Unity module of the International Space Station. In space continuous for less than 14 days astronauts experience less than one third reduction in muscle fiber size. Astronauts need to exersixe 2 hours a day.
Beyond low orbit the earth’s atmosphere and magnetosphere are no longer available. The space radiation might put the crew and astronauts in at risk for radiation sickness, and increased lifetime risk for cancer, degenerative diseases, and central nervous system effects. Animal models have to be applied of developed to find or estimate cancer and other risks and diseases. They must be able to predict and find each individual astronauts radiation sensitivity and resistance. Human epidemiology of exposure to various doses of X-rays or gamma-rays gives strong evidence that cancer and other diseases are to be expected from exposures to galactic cosmic rays (GCR) or solar particle events (SPE). Astronauts are exposed to ionizing radiation with effective doses in the range from 50 to 2000 mSv (milli-Sievent).
Physical impact of space travel on the human body
Experiments and scientific advancements for space (ISS)
Canada's contribution the the ISS
Sensor motor cunfusion occurs during adaption to spaceflight and during readaptation to gravity on planetary area. These changes can effect and change control of vehicals and impair useful performance during the keen phase of adaption to novel gravitational environments. Research has shown of the changes in visual performance, manual control, spatial orientation and gait control. The biggest changes happen during period immediately following gravity transition.
Canadian Contribution to the ISS
I will talk about:
Astronauts need to be capable of working and picking up objects using space gloves. Eva gloves are used to protect astronauts from space environments and make working in gloves easier for your fingers to move in.
Primary Life support system
The primary life support system (PLSS) is like a backpack and is worn as one. It provides whatever astronauts need such as tanked oxygen. It removes exhaled dioxide and contains a battery for electrical power. The PPLS also carries water cooling equipment such as a fan to circulate oxygen and a two way radio. There even is a caution and warning system lets astronauts know if something is wrong. The unit is covered with a protective cloth layer.
Canadian Contribution and Technological Advancements
As well as the United States, Russia, Europe and Japan, Canada is a partner in the International Space Station (ISS). The ISS is an orbiting research laboratory. Since the first module of the Station was launched in 1998, the Station has circled the globe 16 times per day at 28,000 km/h at an altitude of about 370 km, covering a distance equivalent to the Moon and back daily. The Station is about as long as a Canadian football field, and has as much living space as a five-bedroom house.

Physical impact of space travel on the human body
To secure Canada’s place among the top space-faring nations and ensure a presence in space for Canadian astronauts, Economic Action Plan 2015 announces that Canada will continue its participation in the International Space Station mission to 2024. The Canadian Space Agency will engage with the National Aeronautics and Space Administration to define the terms of this continued participation.
Canada and the ISS
Since 1989, the Canadian Space Agency (CSA) has promoted the peaceful use and development of space and has been committed to advancing space knowledge for the benefit of Canadians and the world. Thanks to the efforts of the CSA and its partners, Canada has become a world-leader in space robotics and is a partner in the International Space Station.
Since the beginning of when Canada launched Alouette, a satellite to gather data on the ionosphere, and becomes the third nation, after Russia and the United States, to design and build its own satellite and to when the plan for Canada's future in space was unveiled we certainly done alot.
