High above planet Earth, a human helps a sick machine. The machine is the Hubble Space Telescope (HST), which does not appear in the image. The human is astronaut Steven L. Smith, and is seen recovering a mechanical tool from the railing of the Remote Manipulation System before resuming work at the HST in December 1999.
For most astronauts, space is not a place to relax and take vacations, but rather a place for hard work. Since many space missions involve expensive equipment and complicated experiments, astronauts are generally people of considerable knowledge and training.
Although the hours may be long and the work can be exhausting, a frequently reported benefit of working in space is the vision of a spectacular panorama.
