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:
“No being exists or can exist which is not related to space in some way. God is everywhere, created minds are somewhere, and body is in the space that it occupies; and whatever is neither everywhere nor anywhere does not exist. And hence it follows that space is an effect arising from the first existence of being, because when any being is postulated, space is postulated.”
—Isaac Newton (1642–1727)
“Why not a space flower? Why do we always expect metal ships?”
—W.D. Richter (b. 1945)
“Sir Walter Raleigh might well be studied, if only for the excellence of his style, for he is remarkable in the midst of so many masters. There is a natural emphasis in his style, like a man’s tread, and a breathing space between the sentences, which the best of modern writing does not furnish. His chapters are like English parks, or say rather like a Western forest, where the larger growth keeps down the underwood, and one may ride on horseback through the openings.”
—Henry David Thoreau (1817–1862)
