Why do we need to go to Mars?
It is an ideal place to search for the residues of microbial life, test new technologies, and lay the groundwork for human exploration down the road. The mission plans to investigate whether microbial life existed on Mars billions of years ago and therefore that life is not unique to Planet Earth.
What are 2 benefits to space exploration?

- Protecting our planet and our environment.
- Creating scientific and technical jobs.
- Improving our day-to-day lives.
- Enhancing safety on Earth.
- Making scientific discoveries.
- Sparking youth’s interest in science.
- Cooperating with countries around the world.
What happens to your eyes in space?
They found classic symptoms of what is now known as Space-Associated Neuro-Ocular Syndrome (SANS). Symptoms include swelling in the optic disc, which is where the optic nerve enters the retina, and flattening of the eye shape.
Can being in space make you blind?
Spaceflight-induced visual impairment is hypothesized to be a result of increased intracranial pressure. Although reported signs and symptoms have not appeared to be severe enough to cause blindness in the near term, long term consequences of chronically elevated intracranial pressure is unknown.
What is the biggest problem with space travel?
Problem: Space travel can present extreme environments that affect machine operations and survival. Like humans, machines are impacted by gravity, propulsive forces, radiation, gases, toxins, chemically caustic environments, static discharge, dust, extreme temperatures, frequent temperature variations and more.
How does space change the human body?
Without the proper diet and exercise routine, astronauts also lose muscle mass in microgravity faster than they would on Earth. Moreover, the fluids in the body shift upward to the head in microgravity, which may put pressure on the eyes and cause vision problems.
What happens to your brain in space?
These MRI images showed that, with long-duration exposure to microgravity, the brain swells and cerebrospinal fluid, which surrounds the brain and spinal cord, increases in volume.
What are the challenges of going to Mars?
Radiation, microgravity, and astronaut health. Isolation and psychological issues. Communications (in transit and on Mars)
Is this the first landing on Mars?
Mars 3 arrived at Mars on December 2, 1971. The lander was released and became the first successful landing on Mars. It failed after relaying 20 seconds of video data to the orbiter.
What is the biggest problem in space?
But in reality, scientists are finding that the biggest obstacle to today’s space travel is dust.
Is space exploration necessary essay?
There are so many wars and illnesses. We can spend money and time more effectively on Earth. Other people say that space exploration is a waste of time and money. It seems to me that space exploration it is very important to humanity because we always want to know more about us, about world we live in.
Who went blind in space?
What are the dangers of going to Mars?
Difficulties and hazards include radiation exposure during a trip to Mars and on its surface, toxic soil, low gravity, the isolation that accompanies Mars’ distance from Earth, a lack of water, and cold temperatures.
Does space affect human body?
Venturing into the environment of space can have negative effects on the human body. Additional symptoms include fluid redistribution (causing the “moon-face” appearance typical in pictures of astronauts experiencing weightlessness), loss of body mass, nasal congestion, sleep disturbance, and excess flatulence.
Can astronauts lose their eyesight in space?
A study found that the vision deterioration in astronauts is likely due to the lack of a day-night cycle in intracranial pressure. Researchers found that in zero-gravity conditions, intracranial pressure is higher than when people are standing or sitting on Earth, but lower than when people are sleeping on Earth.
What should astronauts avoid?
Salt and pepper are available but only in a liquid form. This is because astronauts can’t sprinkle salt and pepper on their food in space. The salt and pepper would simply float away. There is a danger they could clog air vents, contaminate equipment or get stuck in an astronaut’s eyes, mouth or nose.
What is a problem in space?
Abstract. Several consistent medical problems have been encountered by astronauts during space flights. These include vestibular dysfunction, weight loss, increase in height, upward fluid shift, anemia, cardiovascular deconditioning, muscle atrophy, and bone loss.
Why is space exploration important?
Human space exploration helps to address fundamental questions about our place in the Universe and the history of our solar system. Through addressing the challenges related to human space exploration we expand technology, create new industries, and help to foster a peaceful connection with other nations.
Which is the first country to land on Mars?
The Viking success The first successful landing on Mars came on July 20, 1976, when NASA’s Viking 1 lander touched down in Chryse Planitia (The Plains of Golf).
