Transporting equipment on EVAs may be done many ways. An Apollo astronaut demonstrates an early method of moving with the film magazine awkwardly tethered to his wrist.

[Here they do the task in] a more controlled manner using a mechanical system such as this extendible boom.

Another astronaut delivers and recovers film magazines for the solar telescopes. The magazines weigh seventy-five Earth pounds (about thirty kilograms).

The boom of "S" shape cross section made of thin steel extends and rewinds on a spool.

Even though the boom was very effective, the astronauts also accomplished this task using a close loop pull-around cable system called a "Brooklyn clothesline".

It is sometimes difficult for a designer or an engineer to keep in mind how easy it is to move large, Earth-heavy objects in weightlessness. There is a limit, of course, but the astronaut is able to move a large satellite weighing about twelve hundred Earth pounds. When installed on the shuttle, the Remote Manipulator System can be used to transfer hardware, move satellites to or from the payload bay, and retrieve satellites from space for an in-orbit repair or the return of the satellite to Earth.
