Dan Schlund flying in a jet pack (Rocketbelt) A jet pack, rocket belt, rocket pack or flight pack is a device worn as a backpack which uses jets to propel the wearer through the air. The concept has been present in science fiction for almost a century and the first working experimental devices were demonstrated in the 1960s.
The term artificial objects is closely associated with made by humans or not naturally occurring items that have been sent into space.

If an untethered astronaut were to lose physical contact with the vessel, it would provide free-flying mobility to return to it. It is worn on spacewalks outside the International Space Station (ISS), and was worn on spacewalks outside the Space Shuttle. So far, there has not been an emergency in which it was needed.
The Manned Maneuvering Unit (MMU) is a propulsion backpack which was used by NASA astronauts on three space shuttle missions in 1984. The MMU allowed the astronauts to perform untethered EVA spacewalks at a distance from the shuttle. The MMU was used in practice to retrieve a pair of faulty communications satellites, Westar VI and Palapa B2.
Elliptical galaxy M87 emitting a relativistic jet, as seen by the Hubble Space Telescope Relativistic jets are beams of ionised matter accelerated close to the speed of light. Most have been observationally associated with central black holes of some active galaxies , radio galaxies or quasars , and also by galactic stellar black holes ...
The probe passed the heliopause at 121 AU on August 25, 2012, to enter interstellar space. [7] Voyager 1 is still active. In about 40,000 years the star Gliese 445 (AC +79 3888) and the Sun will fly past each other at a distance of 3.45 light-years, after being currently 17.6 light-years from each other, [ 8 ] with Voyager 1 coming as close as ...
Bell Aerosystems began development of a rocket pack which it called the "Bell Rocket Belt" or "man-rocket" for the US Army in the mid 1950s. [1] It was demonstrated in 1961 but 5 gallons of hydrogen peroxide fuel needed for 21 seconds of flight time did not impress the army.
