They weren't weightless. They weighed 1/6 as much as they weighed on Earth. They were carrying backpacks that weighed about 80 pounds on earth. They compensated for the extra weight on their backs by leaning forward to keep their center of gravity centered above their feet so they wouldn't fall over.
Astronauts undergo extensive training prior to launching into space. The training includes simulators, such as vacuum chambers, parabolic flights, and neutral balance facilities.
the astronauts use poles to move around their ship and can do a swim like action to move around the craft

The answer is an umbilical cord. It keeps astronauts from floating out into the universe.
yes. the space suit does protect astronauts for harmful rays from the sun
Spacelab ( not used now) and Columbus.
Why have scientists developed exercises for astronauts living in outer space for long periods of time? Due to lack of gravitational field all the systms of the body but especially the musculoskeletal system is affected, in terms of bone resorption. To mninimize the effects of zero gravity exercises are developed.
Silly putty was used by astronauts to stop their tools from flying around the spacecraft/shuttle, whilst they were in space. This is because there is no gravity in space, which means that everything will float about the vehicle, and not fall to the floor.
They have to train to get used to weightlessness , and get over travel sickness as well, and the instruments as well.
it is used to take astronauts and cargo into space
The Modified B-707 (or K/C-135) used for low gravity training, (astronauts, etc.). It flew a paraboloic curve that simulated weightlessness.

Astronauts use a variety of tools while in space. For instance, astronauts use specially designed tools, like hammers and wrenches, that are made to be used with unwieldy space suits.

Practice and lots of trips.
Spacelab ( not used now) and Columbus.
Th astronauts used it for brushing their teeth up in space. Since ther is no gravity in space they had to swallow it.
they used a module that carried them back
gravity and oxygen
They use toilets
