In Russia, until the end of March, they will make a sample of the “jetpack” for astronauts
Safety of astronauts during spacewalks with the ISS is provided by safety halyards and special handrails. Installations for movement and maneuvering are necessary in cases when the astronaut for any reason turns out to be unfastened from the station. The CEO of Zvezda Star, Sergey Pozdnyakov, told TASS that a demonstration sample of the new jetpack will be ready this month. Now, on the ISS, an astronaut rescue installation, developed on the same SPE, is used.
A little bit about how astronauts maneuvered in outer space since 1965 - under the cut.

On June 3, 1965, American astronaut Edward White went out into space and used the HHMU, a “manual maneuvering device,” or “jet gun.” The device threw a stream of gas, allowing the astronaut to head in the right direction. In the open space, HHMU was used twice, Edward White on Gemini 4 and Michael Collins on Gemini 10. Device drawbacks: firstly, a busy hand, secondly, low accuracy - you have to manually operate the gun, choosing a target by eye.

The MMU - The Manned Maneuvering Unit - was first tested by Bruce McCandless on the STS-41-B shuttle in 1984. This unit weighing 150 kilograms had 24 micromotors, the fuel for which was two cylinders with compressed nitrogen weighing 6 kilograms. In 1994, all working devices — and two of them were built — went to museums: NASA decided that their use was too dangerous.
The mass of the device with a full charge was 148 kilograms. The characteristic speed is 25 meters per second. McCandless managed to move away from the shuttle to 97.5 meters using the device.
In the USSR, the installation of the movement and maneuvering of astronauts for the Mir station and the Buran spacecraft was developed; in 1990, Alexander Serebrov and Alexander Viktorenko experienced it during a spacewalk. UPMK was a knapsack propulsion system with a remote control panel. The installation was worn over the suit and allowed, thanks to two twenty-liter cylinders with compressed air, to reach a characteristic speed of up to 30 meters per second. Air was exhausted through 32 nozzles.
The installation remained at the Mir station , which was flooded in 2001.
Now on the ISS, American astronauts use SAFER, and Russian cosmonauts use a USK produced by Zvezda . The cosmonaut rescue installation is attached to the Orlan-M spacesuit and subsequent modifications. The photograph shows NASA astronaut John Phillips in the Orlan-M spacesuit equipped with such an installation.

In 2014, Zvezda began to work on a new “knapsack”. The head of the company told TASS that in March a demo sample will be ready, which can be tested on a special stand. After that, he will be presented to representatives of Roskosmos, the Cosmonaut Training Center and other organizations.
