An astronaut landing on Pluto would need to wear a spacesuit that is not much different from those used now for spacewalks in orbit of Earth.
An astronaut suit.
If he took a monkey with him, presumably for scientific purposes, it would need to wear a suit just like the astronaut so it could breath and be protected from space.
While visiting Pluto, you would need to wear a space suit to protect yourself from extreme cold temperatures, lack of breathable air, and radiation from the sun. Additionally, you would need specialized equipment to ensure your safety and survival in the harsh environment of the dwarf planet.
An astronaut.
you can on earth but you would have to wear a astronaut suit with oxygen to breathe because there is no oxygen in the atmosphere
Where would they go? Just make sure you wear your space suit when you leave your life-supporting vessel.
This depends upon where the astronaut is. Inside the International Space Station, astronauts usually wear light, informal clothing. If the astronaut exits the station to do a space walk or other such mission, the astronaut will wear an air tight space suit, in order to be able to continue breathing.
She wear's it because mammals can't breathe underwater.
Because there is no AIR in space, and we need AIR (that is in very simple terms....).
Pluto was the god of the underworld which is associated with death, so he would wear black.
If you could visit the mesosphere, you would need to wear a full pressure suit or a spacesuit like an astronaut since the mesosphere is above the Earth's atmosphere and lacks oxygen necessary for breathing. The extreme cold temperature in the mesosphere also requires thermal protection provided by these specialized suits.
You would need clothing with several different degrees of insulation, ranging from heavy, through very heavy, extremely heavy, awesomely heavy, and astronomically heavy, to incredibly heavy and impractically heavy.
