Space
Rocket packs can be useful for extra-vehicular activity (EVA) in outer space. While near Earth a jet pack has to produce a g-force of at least 1g (otherwise it just provides some steering capacity for the wearer while falling down to Earth). For excursions outside a free falling spaceship, even a small g-force is already sufficient for a small deviation from free fall, hence much less delta-v is consumed per unit time, and not during the whole EVA. With only small amounts of thrust needed, safety and temperature are much more manageable than in the atmosphere in Earth's gravity field.
Rocket packs were tested during mission STS-64. Mission specialists Carl Meade and Mark Lee tested the SAFER Rocket Pack while Hammond remained inside the Orbiter.

Famous quotes containing the word space:
“The limitless future of childhood shrinks to realistic proportions, to one of limited chances and goals; but, by the same token, the mastery of time and space and the conquest of helplessness afford a hitherto unknown promise of self- realization. This is the human condition of adolescence.”
—Peter Blos (20th century)
“Time in his little cinema of the heart
Giving a première to Hate and Pain;
And Space urbanely keeping us apart.”
—Philip Larkin (1922–1986)
