A space suit typically weighs around 280 pounds (about 127 kilograms) while on Earth. However, in the microgravity environment of space, the weight is not as significant due to the lack of gravity. The bulk and weight of the suit are necessary to protect astronauts from the harsh conditions of space, including extreme temperatures, radiation, and micrometeoroids.
Space suits are equipped with various systems for life support, temperature control, and mobility, which all add to the overall weight. While the suit can be cumbersome on the ground, it is designed to grant astronauts the flexibility they need while conducting extravehicular activities (spacewalks) outside their spacecraft.
