Astronaut

the shuttle that most NASA astronauts will stay in orbits 350 km above Earth, with a gravitational pull 90% stronger than it is on the ground (NASA Space Bones). Giancoli describes objects orbiting the Earth as feeling weightless because they are, in essence, free falling towards Earth. The force of gravity causes objects orbiting Earth to “fall” from their normal, straight path as the only force applied on them is gravity. The free falling sensation felt by the astronauts in space is the same…

cosmic and solar radiation are very bad for astronauts working in space to be exposed to, because they can get low blood count, radiation sickness’s, cataracts, melanoma, cancer… and potentially even death. Luckily their are a few scientific and natural solutions to prevent astronauts from being exposed to radiation from space, but their are no solutions which can completely prevent astronauts from being exposed. One of the things which prevent astronauts from being exposed to solar radiation…

destination. It was April 13th, 1970, the three astronauts only needed one more day to get started with their mission. Everything seemed as normal as a baby crying when it’s born, that was until there was a loud bang that made the spacecraft moan and shudder! At first, the three astronauts came to the conclusion that a meteor had hit them. What had actually happened was that when they were doing the routine task to turn…

exploration can also lead astronauts to chronic boredom. We do not need to be use money on things we don’t need. America may be rich altogether, but lots of the people in it are not, lots of our people live in poverty and face hunger. Our government still decides to invest in space exploration instead of our hungry people. In the article “Leaving Main Street” from our Pearson Realize book unit two a man named Michael Griffin says, “ When we contemplate…

both astronaut A and B cooperate and work together. This would present the lowest risk of total deaths, because each astronaut has a 90% chance of surviving. What is the best option for each Astronaut thinking only of him or herself? The best option for astronaut A, when only thinking of him or herself, would be if he/she runs (or deflects) and astronaut B cooperates. This would provide astronaut A with a 98% chance of surviving and only allow a 20% chance of survival for astronaut B.…

The Apollo Space Program was very important to many Americans and NASA because it dealt with sending astronauts into space and exploring the unknown solar system. That is why on April 11th, 1970, NASA launched three astronauts into space. This launch is known as Apollo 13, or the 13th launch out of Earth’s solar system. NASA sent three men, Jim Lovell, Fred Haise, and Jack Swigert, into space on the Apollo 13 mission. Initially, Lovell, the commander, and Haise, the lunar module pilot, were…

The documentary, MAKERS: Women in Space, discusses and addresses the journey and struggles of female astronauts, before being allowed to go into space by NASA. The documentary discusses the history of the U.S. space program and specifically focuses on women in space. Women’s involvement in getting to space started with the Lovelace: Women in Space Program, which explored the idea of women going to space that tested their physical and medical fitness, however this program was shut down in 1962.…

in human history. What would it be like if we could travel to another solar system or even another galaxy? The things we could learn and experience would be astronomical. But, before we can dream of getting to that point of scientific discovery, astronauts have to face a number of physical and mental challenges are brought about during long-term space missions. Living in space for extended periods of time bring about consequences on the human body including: loss of bone density, muscle atrophy,…

Apollo 13 was a research mission to the moon. Halfway through the mission, the space ship blew up. America thought the astronauts were doomed, but the people at mission control thought otherwise. They brought astronauts back home alive. They never did make it to the moon. Apollo 13 mission was a success for many reasons. The first reason is that they came back alive. After having half of there oxygen supply blown out into space and there being depleted fast, they pulled through. The reason for…

The historic launch of the Apollo 11 mission carried three astronauts toward the moon. Two astronauts Neil Armstrong and Buzz aldrin set foot on the moon for the first time in human history as 530 million people around the world watched their mission on television. The first moon landing was launched on july 16 1969 in order to complete a national goal set by President John F. Kennedy. Apollo 11 was the first manned mission to land on the Moon. The first steps on the moon were taken by Neil…
