In space there is only vacum . so if any particle on substance comes into space then it would expand until it pops up.so if humans go into space without a space suit then they would expand until they blow up messy.
A space suit typically has multiple layers, usually around 11 layers, to provide protection for the astronaut from extreme temperatures, micrometeoroids, and radiation, as well as to regulate temperature and provide life support functions. Each layer serves a specific purpose to ensure the astronaut's safety and comfort in the harsh environment of space.
Each manned Mercury launch carried a single astronaut. Gemini ... two Apollo ... three Shuttle ... several
The helmet in a space suit provides protection by creating a sealed environment to maintain pressure and ensure the astronaut can breathe. It also includes a visor to shield the eyes from harmful radiation and debris in space. The helmet may have communication systems for astronauts to communicate with each other and ground control.
An astronaut needs proper nutrition, exercise, and sufficient rest each day to maintain their physical and mental health while in space. They also require a controlled environment with oxygen, water, and a safe living space to support their basic needs.
Astronaut ranks can vary by space agency, but common ranks include: Astronaut Candidate (trainee status), Mission Specialist (focused on specific tasks during missions), Pilot Astronaut (responsible for flying the spacecraft), and Commander (in charge of the mission and crew). In some agencies, there are also ranks like Chief Astronaut or Flight Engineer for more specialized roles. Each rank reflects the astronaut's level of experience and responsibilities during space missions.
Mercury carried one Astronaut, Gemini carried two, and Apollo three
Yes
An astronaut needs to drink about 3 liters of water per day while in space to stay hydrated. This amount is higher than on Earth due to the effects of microgravity on the body, which can lead to accelerated dehydration.
In space each course is in a disposable container, which is strapped to the astronaut's meal tray, which is strapped to his lap. When all the courses are finished, the containers are put into a trash compactor to eliminate waste.
The image space is the 2D plane of the image where pixels are located. It represents the spatial space of the image. In other words, when we talk about the location of each pixel in an image, we are talking about image space. On the other hand, feature space is about the radiometric values assigned to each pixel. In case of a grey-scale imagery, only one radiometric value is assigned to each pixel. When we say an image is RGB or multispectral, then each pixel has several radiometric values that are stored in different channels (for instance there are 3 channels of Red, Green and Blue in an RGB image, so for a pixel we have 3 radiometric values). Feature Space is the space of these radiometric values; the radiometric values of each pixel can be plotted in that space and you can create a feature space image. Last example, an RGB image has a 3 dimensional feature space while it still has a 2D image space.
The result would be the same as on Earth (except in 3D). Something different would happen (i) if the astronaut let go of one magnet before the other or (ii) if there were two astronauts, with one magnet each. (In space, the astronaut could spin, as well (except much more slowly).)
While John Glenn is usually given credit, as he was the first American to orbit the Earth, the first in space was actually Alan Shepard Jr. (1923-1998). Shepard, a US Navy pilot, became the first US astronaut in space on May 5, 1961, followed by fellow astronaut Gus Grissom on July 21. These were both sub-orbital flights of approximately 15 minutes each. John Glenn became the first US astronaut in orbit, making three orbits on February 20, 1962.The first "man in space" was the Soviet cosmonaut Yuri Gagarin (1934-1968), on April 12, 1961.
