What is the effect of space vacuum pressure on astronauts during extravehicular activities?
The space vacuum pressure can cause a variety of effects on astronauts during extravehicular activities, including the potential for decompression sickness, known as "the bends," and the expansion of gases in the body which can lead to tissue damage. Additionally, the lack of atmospheric pressure can cause a rapid drop in body temperature and the potential for the lungs to collapse. Astronauts must wear specialized suits to protect themselves from these effects while working in the vacuum of space.

What is the impact of the vacuum of space pressure on astronauts during a spacewalk?
The vacuum of space pressure can cause a variety of health issues for astronauts during a spacewalk. Without the pressure of Earth's atmosphere, bodily fluids can boil, leading to swelling and potential damage to tissues. Additionally, the lack of pressure can cause the lungs to expand, making it difficult to breathe. Overall, the vacuum of space pressure can be harmful to astronauts if they are not properly protected.
Where does air go in space and how does it affect astronauts during space missions?
In space, there is no air because it is a vacuum. This lack of air affects astronauts during space missions because they cannot breathe without a spacesuit or the controlled environment of their spacecraft. Additionally, the absence of air means there is no atmosphere to protect astronauts from harmful radiation and extreme temperatures.
What impact does the movement on the moon have on the behavior of astronauts during space missions?
The movement on the moon affects astronauts' behavior during space missions by causing them to experience reduced gravity, which can lead to changes in their balance, coordination, and muscle strength. This can impact their ability to move around and perform tasks in space.
What type of pressure do humans breathe with?
Humans breathe with atmospheric pressure, which is the pressure exerted by the weight of the Earth's atmosphere. This pressure allows air to flow into our lungs during inhalation and out during exhalation.
How does intrapleural pressure change during quiet breath?
During quiet breathing, the intrapleural pressure decreases during inspiration as the diaphragm contracts and the thoracic cavity expands, leading to a decrease in pressure inside the lungs. During expiration, intrapleural pressure increases as the diaphragm relaxes and the thoracic cavity decreases in volume, causing an increase in pressure inside the lungs.
What is a space suit used for?
A space suit is used to protect astronauts from the harsh conditions of outer space, including extreme temperatures, micrometeoroids, and lack of atmosphere. It also provides oxygen and helps regulate pressure for astronauts to be able to work outside the spacecraft during spacewalks or extravehicular activities.
Why do astronauts need to wear special suit?
Astronauts wear special suits, known as space suits or Extravehicular Mobility Units (EMUs), to protect them from the harsh conditions of space, including extreme temperatures, vacuum, and radiation. These suits provide life support by supplying oxygen for breathing and removing carbon dioxide, while also maintaining pressure around the body. Additionally, they are designed to keep astronauts safe from micrometeoroids and other debris, ensuring their safety during spacewalks and other extravehicular activities.
What is the name of the uniform that astronauts were?
Astronauts wear a space suit during extravehicular activities (spacewalks) outside the spacecraft. Inside the spacecraft or space station, they typically wear a blue flight suit or other specialized clothing for comfort and safety.
What does NASA call a spacewalk?
they call in an EVA (Extravehicular Activity)
Who invented the space suit?
The space suit was invented by a team of engineers at the International Latex Corporation (ILC) in 1961. It was developed to protect astronauts during spacewalks and other extravehicular activities in space.
How does a space helmet work?
A space helmet provides a sealed environment for astronauts, protecting them from the vacuum of space, extreme temperatures, and harmful radiation. It also provides a supply of oxygen for breathing and helps regulate temperature and pressure inside the helmet to keep the astronaut safe and comfortable during spacewalks or extravehicular activities.
How many separate parts does a spacesuit have?
A typical spacesuit, such as the NASA Extravehicular Mobility Unit (EMU), consists of several separate parts, usually totaling around 14 to 15 key components. These include the helmet, gloves, boots, and the torso, along with various layers for thermal insulation, pressure, and mobility. Each part is designed to provide specific functions, such as life support, protection from space conditions, and mobility for astronauts during extravehicular activities.
How do astronauts train for an EVA or extravehicular activity?
Astronauts train for extravehicular activities (EVAs) by practicing in neutral buoyancy pools to simulate microgravity, completing virtual reality simulations, and studying procedures and equipment. They also undergo physical conditioning to prepare for the demands of working in space suits for several hours at a time. Communication and teamwork skills are also emphasized during training.
How were cordless tools originally used in space?
Cordless tools were first used in space during the Gemini program in the 1960s. They were used to allow astronauts to conduct experiments and repairs during spacewalks without being tethered to the spacecraft. This helped improve astronaut mobility and efficiency during extravehicular activities.
Why would astronauts wear special suits if they went outside of the space shuttle in the thermosphere?
Astronauts wear special suits, known as spacesuits, when going outside the space shuttle in the thermosphere to protect themselves from the harsh environment. These suits provide life support by supplying oxygen, regulating temperature, and maintaining pressure, as the thermosphere has extreme temperatures and lacks breathable air. Additionally, spacesuits shield astronauts from harmful radiation and micro-meteoroids, ensuring their safety during extravehicular activities.
What is the impact of pressure in space on astronauts during extravehicular activities?
The impact of pressure in space on astronauts during extravehicular activities can lead to decompression sickness, also known as "the bends." This occurs when the pressure around the astronaut decreases rapidly, causing nitrogen bubbles to form in the bloodstream. Symptoms can include joint pain, dizziness, and fatigue. To prevent this, astronauts must undergo a process called "pre-breathing" to adjust their bodies to the lower pressure before going outside the spacecraft.
Why are space gloves important?
Space gloves are essential for astronauts as they protect their hands from the harsh conditions of space, including extreme temperatures, vacuum, and micrometeoroids. They provide dexterity and grip, allowing astronauts to perform intricate tasks while wearing bulky spacesuits. Additionally, these gloves are designed to maintain pressure and offer insulation, ensuring the safety and functionality of astronauts during extravehicular activities (EVAs). Overall, space gloves are a critical component of space suits that enable safe and effective operations in the outer space environment.
