In 1982, National Security Decision Directive wanted NASA to focus on making a fully operational space shuttle program. The program was to be cost efficient and have at twenty-four flights per year. By 1985 though, NASA had only managed nine flights for a given year. The shuttle they were using was nine-billion dollars, and wasn’t cost efficient as desired. Then, in 1986, NASA planned its largest number of flights yet. They had fifteen scheduled flights, one that would involve a teacher in the…

Spaceflight Osteopenia (Bone Atrophy) Spaceflight osteopenia refers to the reduction in bone density that occurs during space travel. The depletion of bone mass experienced by astronauts could weaken the bones and is a consequential side effect of extended spaceflight. This could present critical problems when the astronauts return to a weight-bearing environment such as the Earth. Researchers speculate the number one cause of bone atrophy in space is weightlessness, where both the astronauts…

On June 4, 1974 was the beginning of the construction on the Challenger space craft. NASA tried many different materials to build it and each time they came up with a new idea they tested the space craft to see if it was a good idea. They finally decided to use and O-ring. An O-ring is a packing or a toric joint that is in the shape of a circle. It is met to fit tightly between two pieces of metal. An O-ring is not designed to fly in unusually cold conditions. The Challenger was built to serve…

The goal of this project was to build a rocket with three fins, that can launch 100 M into the air and fall down to the earth without the egg breaking. It had to be done by November 2. Some constraints that we had to follow that limited our design was that we could only use recyclable materials, and we couldn’t use heavy materials such as metal or wood. We also didn’t have any instructions to follow, every idea came from our brains or the internet. My group decided on a design based on the…

Apollo Missions There were many steps that were taken before the Apollo missions began. For one, there was the Gemini missions. These were meant to prove that life could be sustained in space. After they worked, and this was proven, scientists then moved to their next step. The next step was proving that a person could live in space. They took baby steps by starting with a few days and moving up to two weeks. After this was proven to be true, then scientists developed the Apollo…

NASA Space Shuttle is the first reusable space shuttle in the world and used to deliver astronauts and cargos into space and return to the Earth. The success of the space shuttle getting through the catastrophic forces when travelling into space and back again in serviceable form was credited to the ingenious engineers. First, the rocket engineers faced the problem that without any protection, the engines would self-destruct under extreme temperatures when travelling huge distances. In fact, at…

Space Exploration Synthesis Essay I believe space exploration is the next step that is necessary for all of humanity to take. The benefits of space exploration far outweigh the costs in this matter. But I believe certain regulations and precautions need to be taken into consideration to ensure this next huge step that humanity is on the verge of taking, will be in the right direction. First off, I think we need to address the main concern when discussing space exploration, which is cost. In…

People have heard about the most famous contributors to space travel such as Neil Armstrong and Buzz Aldrin. However, the woman who made space travel possible, Katherine Johnson, has not been properly recognized for her contribution to the exploration of space. Johnson was a NASA mathematician who who calculated the trajectories of objects in space. Despite the oppression she underwent because of her race and gender, she was still able to accomplish many feats and refused to be ignored. She was…

Recently there has been a proposal that the government should cease funding to space exploration programs, and instead use the money for public education. Some people might argue that this is the way to go. However, I believe that if we honor this proposal we are limiting ourselves as a human race. First, we live in just a small speck of the Universe, and it is hard to believe that we are the only living creatures within that universe. Second, putting more money into the education system maybe…

When asked who they would want to spend the afternoon with, many people would respond with names approximative to the likes of George Washington or Albert Einstein. This is justifiable- both were noteworthy men who accomplished a substantial amount in their lifetime. Others would respond with people close to them who bear a great deal of influence on their lives, such as parents or friends. There are many significant individuals throughout history and people who have played important roles in my…
