Uzlovoy Module
''Prichal'' (), also known as the Uzlovoy Module (UM, ) is a Russian-built component of the International Space Station (ISS). This spherical module has six docking ports (forward, aft, port, starboard, zenith, and nadir) to provide additional docking ports for Soyuz and Progress spacecraft, as well as potential future modules. ''Prichal'' was launched on 24November 2021, at 13:06:35UTC, atop a Soyuz-2.1b rocket and guided automously into the nadir port of the '' Nauka'' module by a Progress M-UM spacecraft attached to the ''Prichal''s nadir port. Once in place, the Progress spacecraft disconnected for a destructive reentry. As of 2024, the forward, aft, port and starboard docking ports remain covered. ''Prichal'' was initially intended to be an element of the now canceled Orbital Piloted Assembly and Experiment Complex (OPSEK).

International Space Station
The International Space Station (ISS) is a large space station that was Assembly of the International Space Station, assembled and is maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), European Space Agency, ESA (Europe), JAXA (Japan), and Canadian Space Agency, CSA (Canada). As the largest space station ever constructed, it primarily serves as a platform for conducting scientific experiments in microgravity and studying the space environment. The station is divided into two main sections: the Russian Orbital Segment (ROS), developed by Roscosmos, and the US Orbital Segment (USOS), built by NASA, ESA, JAXA, and CSA. A striking feature of the ISS is the Integrated Truss Structure, which connect the station’s vast system of solar panels and Spacecraft thermal control, radiators to its pressurized modules. These modules support diverse functions, including scientific research, crew habitation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Progress (spacecraft)
The Progress () is a Russian expendable cargo spacecraft. Originally developed for the Soviet space program and derived from the crewed Soyuz (spacecraft), Soyuz spacecraft, Progress has been instrumental in maintaining long-duration space missions by providing consumables like food, water, and air, as well as maintenance equipment. Since its maiden flight in 1978, Progress has supported various space stations, including Salyut 6, Salyut 7, and Mir, and remains a key resupply vehicle for the International Space Station (ISS). Each Progress mission delivers thousands of kilograms of supplies in its pressurized module. It also carries water, fuel, and gases to replenish the station's resources and sustain its onboard atmosphere. Beyond resupply duties, a docked Progress can maneuver or reboost the station, countering atmospheric drag and maintaining its operational altitude. When a Progress spacecraft nears the end of its design life, it is loaded with waste, undocked, and deorbit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Protective Equipment
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemical, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. ''Protective clothing'' is applied to traditional categories of clothing, and ''protective gear'' applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit. The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering controls and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expedition 66
Expedition 66 was the 66th long-duration expedition to the International Space Station. The mission began after the departure of Soyuz MS-18 on 17 October 2021. It was commanded by European Space Agency astronaut Thomas Pesquet, the fourth European astronaut and first French astronaut to command the ISS until 8 November 2021 when Russian cosmonaut Anton Shkaplerov, who arrived aboard Soyuz MS-19, took over his command.

Solar Panels On Spacecraft
Spacecraft operating in the inner Solar System usually rely on the use of power electronics-managed photovoltaic solar panels to derive electricity from sunlight. Outside the orbit of Jupiter, solar radiation is too weak to produce sufficient power within current solar technology and spacecraft mass limitations, so radioisotope thermoelectric generators (RTGs) are instead used as a power source.NASA JPL Publication: Basics of Space Flight, Chapter 11. Typical Onboard Systems, Electrical Power Supply and Distribution Subsystems, History The first practical silicon-based solar cells were introduced by Russell Shoemaker Ohl, a researcher at Bell Labs in 1940. It was only 1% efficient. In April 25, 1954 in Murray Hill, New Jersey. They demonstrated their solar panel by using it to power a small toy Ferris wheel and a solar powered radio transmitter. They were initially about 6% efficient, but improvements began to raise this number almost immediately. Bell had been interested in t ...

Helium
Helium (from ) is a chemical element; it has chemical symbol, symbol He and atomic number 2. It is a colorless, odorless, non-toxic, inert gas, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the Chemical element, elements, and it does not have a melting point at standard pressures. It is the second-lightest and second-most Abundance of the chemical elements, abundant element in the observable universe, after hydrogen. It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and Jupiter, because of the very high nuclear binding energy (per nucleon) of helium-4 with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, ...
