STSC Questions #1-7:

1- It helps improve our understanding of Earth, our solar system, and the origins of everything around us.

2- Spinoff is a byproduct or incidental result of a larger project.

Three examples of Space Spinoffs:

* Product – Dehydrated Food: The purpose for this product was to provide astronauts with meals during long flights. A Spinoff of this product could be portable camping food; emergency food supply; food storage.

* Product – Miniaturized Computer and Robotics: The purpose of this product to build computer robotics for space vehicles and probes. A spinoff of this product could be Emergency response robots (to inspect explosive devices)

* Product – Ionization Smoke Detector: The purpose of this product was to detect possible fire outbreaks on board a spacecraft. A Spinoff would be sensitive household smoke detector.

3- One of Canada’s most significant contributions to the space station has been the Canadarm2, this robotic device was used to move astronauts around as they work outside the space station. It can also bend around corners and grasp objects with its computer- controlled fingers.

4a - An artificial body placed in orbit around the earth or moon or another planet in order to collect information or for communication.

4b - A geostationary orbit is a circular orbit, 35,786 kilometres (22,236 mi) above the Earth's equator and following the direction of the Earth's rotation.

4c - Canada's first satellite was called Alouette. When Canada launched Alouette on September 29, 1962, Canada became the third country in the world to have a satellite in orbit, after the Soviet Union and the United States.

4d - Canada’s latest satellite’s name is Cassipoe.

Questions Continued:

5- Four uses for satellites:

* The First use is to make star maps * The Second use would be so theycan be used to study mysterious phenomena such as black holes and quasars * The Third use would be so they can be used to make pictures of the planets in the Solar System. * They can be sued to make maps of different planetary Systems.

6- Hazards or Costs of Travelling to and from Space:

1- Equipment such as satellites and space probes are very expensive. Russia and America both lost hundred of millions of dollars and many hours of labour. 2- Spaceship could be collide with comets, asteroids or any other space debris 3- Loss of human life due to many different malfunctions in space shuttle. 4- High risk of damaging space suit.

7a- Microgravity is very weak gravity, as in an orbiting spacecraft.

7b- Effects of Microgravity on the body:

* Muscles get weaker. * Bones get weaker. * You lose a lot of weight. * Risk of Death.

7c - One way of reducing this is to be very healthy, exercise daily and eat healthy.
