2. What is the first human in space wearing a suit?Yuri Gagarin in the Soviet SK-1 suit on April 12, 1961
3. What is a space suit and why do astronauts wear it?A space suit is a special suit that acts like a tiny spaceship. It keeps the astronaut safe by giving them air, keeping their body fluids liquid, and letting them breathe in the vacuum of space.
4. How does a space suit protect astronauts from the extreme heat and cold in space?The suit has many layers and a cooling system that circulates water to keep the astronaut warm in the dark and cool when the sun shines. It also insulates against the big temperature changes.

Vacuum: A space devoid of matter, characterized by extremely low pressure and absence of breathable atmosphere.
Ionizing Radiation: High-energy particles or waves that can damage biological tissues and electronic equipment, prevalent in space.
Micrometeoroids: Microscopic to pebble-sized particles of rock and dust traveling at hypervelocity in space, posing an impact hazard.
Armstrong Limit: An altitude (approximately 19,000 meters or 62,000 feet) above which the atmospheric pressure is too low for humans to survive without a pressurized suit.
