Modern space suits augment the basic pressure garment with a complex system of equipment and environmental systems designed to keep the wearer comfortable, and to minimize the effort required to bend the limbs, resisting a soft pressure garment's natural tendency to stiffen against the vacuum. A self-contained oxygen supply and environmental control system is frequently employed to allow complete freedom of movement, independent of the spacecraft.
Three types of spacesuits exist for different purposes: IVA (intravehicular activity), EVA (extravehicular activity), and IEVA (intra/extravehicular activity). IVA suits are meant to be worn inside a pressurized spacecraft, and are therefore lighter and more comfortable. IEVA suits are meant for use inside and outside the spacecraft, such as the Gemini G4C suit. They include more protection from the harsh conditions of space, such as protection from micrometeorites and extreme temperature change. EVA suits, such as the EMU, are used outside spacecraft, for either planetary exploration or spacewalks. They must protect the wearer against all conditions of space, as well as provide mobility and functionality.

Hey Queen Messy here!
I believe it is true.
Weight is the way we usually describe what the scales tell us, but our weight is actually something different.
"When you get on the scale and it tells you that you weigh 50 kilograms, that isn't your weight. That's actually your mass", says Dr Nicole Bell from the University of Melbourne.
"In everyday speech weight and mass are used interchangeably, but weight is a figure arrived at by multiplying mass by gravitational acceleration".
Physicists use Newton's 2nd law (F = ma) to describe the forces acting upon an object moving through space, where force is equal to mass times acceleration.
"In the case of weight, we can describe the force as W = mg", says Bell. "That is weight is equal to mass times gravitational acceleration.
Weight is not measured in kilograms, but in Newtons.
