Weight in outer space?
Weight is based on gravity, and if you are in outer space there is no gravity--hence no weight.
Mass, however, refers to the quantity of matter based on Newton's Second Law of Motion, and all matter whether in outer space or not has mass.
A body always has mass. The Weight is dependent on the gravity inflicted on that body. According to F=mg, where Weight is equal to "F", Weight is 0 when gravity is equal to 0. The only place that gravity is 0 is in outer space so there's no weight in outer space but you will always still have a mass.
To date, there have been no experiments conducted on whether people can or cannot walk on water in outer space. since people have no weight in space, water will have no weight or depth in space. As a result, it would be impossible for someone to walk on water without any traction or solid base for them to step on.
A pound is a unit of mass. Mass is constant throughout the cosmos, so if the astronaut has a MASS of 180 pounds on Earth, it will be the same even in space. But, the astronaut doesn't have a weight of 180 pounds. His MASS is 180 pounds. Weight = mass x gravity. So, in space, his weight is 0 Newtons.
