Space probes:

1. Identify three types of space probes, and describe the purpose of each.

This first type of space probe is interplanetary this probe flies by celestial bodies.

The next type of space probe is called an orbiter its jobs is to orbit around a celestial body

The last type of probe is lander this probe is in charge of landing on the surface of the celestial body

Space exploration timeline

2. Describe three milestones in space exploration that you think are interesting (include the date, the name of the mission and or probe ship, and why you think it is important).

November third 1957 was the first animal that was launched into orbit. Sputnik 2 was the name of the launch I think this is important because this was the first animal ever launched into space and if I was in that time I would never think that would be possible.

First manned moon landing was on July 20^th 1969 the name of this mission was called lunar module of Apollo 11 nicknamed The Eagle. I could not find the probe ship name but I chose this because being the first man to land on the moon is a huge milestone

July 20^th 1976 was the U.S first moon landing this mission was called Viking 1. The type of probe ship they used was called an orbiter. I think this mission is important because Mars is a very interesting and mysterious planet and from what I have heard NASA is trying to get people to get there as a second planet for humans.

Humans in Space

1. Explain the relationship between spending time in space and the following

1. Sense of spinning: when astronauts go to space it if very hard to keep balance and stay strait and not spin. One astronaut said t like coming off a ship and not having your land legs underneath you and you. She also said it gives you the sensation of floating.

1. Bones and Muscles: when you are in space it does not required strong bones and muscles including the heart. With out the downward force of gravity the body works considerably less, causing deterioration and loss of bone density. Regular and sometimes over exercising is regularly needed.

1. Body Fluid: on earth with gravity the fluid in our bodies is able to move done to our legs but if there is no gravity they fluid will movie to our heads. If this occurs to much the damage that can happen can involve too much pressure on the optic nerve making your vision impaired.

1. Cosmic radiation: earths magnetic field gives us protection from radiation outside in space. People can’t travel to mars yet because it dosen’t have a magnetic shield so it is unsafe. Right now people are trying to figure out how long people would last or how it could change our DNA. Even though these cautions sound really bad most of the damage can be reversed when returning to Earth.

Space Missions

1. Choose a Canadian astronaut- describe one mission that thy have participated in. Give the personal history of the astronaut.

Chris Hadfield was on the expedition 34/35 on the Soyuz Space craft from December 19^th 2012 to May 13^th 2013. Chris Hadfield became the first Canadian commander of the ISS. The point of his mission was to carry out scientific experiments, operate canadarm2 and perform robotic tasks.

2.Choose a future NASA mission- explain the objective of the mission, and any relevant details (when, where, etc.)

I chose the Mars 2020 mission, there is going to be a rover that is sent there to investigate the key questions about the habitability of Mars and possibly explore the possibility of future human expeditions to Mars. This rover will collect rock and soil samples to bring back to earth and analysis on whether
