Nautilus-X
Nautilus-X (Non-Atmospheric Universal Transport Intended for Lengthy United States Exploration) is a rotating wheel space station concept developed by engineers Mark Holderman and Edward Henderson of the Technology Applications Assessment Team of NASA. The concept was first proposed in January, 2011 for long-duration (1 to 24 months) exo-atmospheric space journeys for a six-person crew. In order to limit the effects of microgravity on human health, the spacecraft would be equipped with a centrifuge. The design was intended to be relatively inexpensive by crewed spaceflight standards, as it was projected to cost US$3.7 billion. In addition, it was suggested that it might only need 64 months of work. The project was cancelled in favour of other projects due to budget constraints. Objectives The original goal of Nautilus-X was to be a stopover to long-term missions for the Moon or Mars. To ease route planning of the whole mission, the station would be placed at the Lagrange p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rotating Wheel Space Station
A rotating wheel space station, also known as a von Braun wheel, is a concept for a hypothetical wheel-shaped space station. Originally proposed by Herman Potočnik in 1929, and popularized by Wernher von Braun in 1952. Specifications This type of station rotates about its axis, creating an environment of artificial gravity. Occupants of the station would experience centrifugal acceleration, according to the following equation: : a = -\omega^2 r where \omega is the angular velocity of the station, r is its radius, and a is linear acceleration at any point along its perimeter. In theory, the station could be configured to simulate the gravitational acceleration of Earth (9.81 m/s2), allowing for human long stays in space without the drawbacks of microgravity. History Both scientists and science fiction writers have thought about the concept of a rotating wheel space station since the beginning of the 20th century. Herman Potočnik introduced a spinning wheel station with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Gravity
Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of reference), as opposed to the force experienced in linear acceleration, which by the equivalence principle is indistinguishable from gravity. In a more general sense, "artificial gravity" may also refer to the effect of linear acceleration, e.g. by means of a rocket engine. Rotational simulated gravity has been used in simulations to help astronauts train for extreme conditions. Rotational simulated gravity has been proposed as a solution in human spaceflight to the adverse health effects caused by prolonged weightlessness. However, there are no current practical outer space applications of artificial gravity for humans due to concerns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Orbital Station
The Lunar Orbital Station (; LOS) is a proposed Russian space station which would orbit around the Moon. The design was presented in 2007 at a conference at the Gagarin Cosmonaut Training Center in Star City, Russia, Star City. It is one of the two parts of the planned Russian lunar infrastructure, the other part being a base on the surface of the Moon. LOS would have six docking ports, a high-power Antenna (radio), antenna for communications, maneuvering and Spacecraft attitude control, attitude control engines, solar panels and a robotic arm. The station components would be launched atop a super heavy version of the Angara rocket. Russia has expressed discontent with its role in the international Lunar Gateway, which prompted the country to go ahead with the planning of its own lunar station. In October 2020, Dmitry Rogozin, director general of Roscosmos, said that the Lunar Gateway program is too “U.S.-centric” for Roscosmos to participate in. In January 2021, Roscosmos a ...

Lunar Gateway
The Lunar Gateway, or simply Gateway, is a planned space station which is to be assembled in orbit around the Moon. The Gateway is intended to serve as a communication hub, science laboratory, and habitation module for astronauts as part of the Artemis program. It is a multinational collaborative project: participants include NASA, the European Space Agency (ESA), the Japan Aerospace Exploration Agency (JAXA), the Canadian Space Agency (CSA), and the Mohammed Bin Rashid Space Centre (MBRSC). The Gateway is planned to be the first space station beyond low Earth orbit. However, the Second presidency of Donald Trump, Trump administration has called for ending the Gateway program in its 2026 budget proposal. The science disciplines to be studied on the Gateway are expected to include planetary science, astrophysics, Earth observation, heliophysics, Astrobiology, fundamental space biology, and Health, human health and performance. As of April 2024, construction is underway o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlas V
Atlas V is an expendable launch system and the fifth major version in the Atlas (rocket family), Atlas launch vehicle family. It was developed by Lockheed Martin and has been operated by United Launch Alliance (ULA) since 2006. Primarily used to launch payloads for the United States Department of Defense, NASA, and commercial customers, Atlas V is the longest-serving active rocket in the United States. Each Atlas V vehicle consists of two main stages. The First stage (rocketry), first stage is powered by a single Russian-made RD-180 engine that burns kerosene and liquid oxygen. The Centaur (rocket stage), Centaur upper stage uses one or two American-made Aerojet Rocketdyne RL10 engines that burn liquid hydrogen and liquid oxygen. Strap-on booster, Strap-on Solid rocket booster, solid rocket boosters (SRBs) are used in several configurations. Originally equipped with AJ-60A SRBs, the vehicle switched to Graphite-Epoxy Motor (GEM 63) boosters beginning in November 2020, except for ...
