The tools that astronauts use in the repair of ships, such as a hammer, saw or screwdriver, resemble the artisan utensils that we use every day. However, these are special fabrications, lighter than conventional ones and at the same time of greater consistency . In addition, it should be taken into account that with the space gloves on, the user's maneuverability is significantly reduced.
Due to the limited space that exists in the ships, only the necessary tools are transported on each trip. To repair the Hubble Space Telescope, a single wrench was used to tighten all the screws and bolts.
During extra-vehicular work, each tool must be attached to a support rope to prevent it from being lost in space in the event of loss, a special vacuum cleaner has even been developed to absorb the chips caused by the saw or drill. To know how to operate with all this equipment in weightless conditions, the astronauts are first thoroughly trained.
