Abstract:

It is necessary to conduct virtual training for astronauts on the ground to improve the efficiency and safety of astronauts carrying objects in space. Cooperation between the two astronauts is required when handling massive objects. During this process, it is necessary to obtain the operating force of each astronaut. The research purpose of this paper was to propose an algorithm to map the astronaut’s operation on the VR handle to the human–machine interaction force without the robot’s participation, thereby saving costs. In this paper, a virtual robot simulation model is established, while th

ObjectiveStudies of mortality among US astronauts are complicated by the healthy worker effect, which predicts lower mortality for astronauts than the general population based solely on the ability to become and remain an astronaut.

Abstract:

The transition of an astronaut into zero gravity leads to a certain restructuring of the body, including the redistribution of fluid flows in it. The process of dehydration of the body is stimulated, the astronaut loses weight. Knowledge of the regularities of changes in an astronaut's body weight, keeping it within normal limits thanks to a rational load distribution, rest, physical exercises, and a well-thought-out diet are extremely necessary in order to provide the astronaut with the most favorable conditions for adaptation in zero gravity, as well as to better prepare him for his return t

Abstract:

In a human-robot communications problem in which a mobile robot and an astronaut are required to work together to maintain network communication, it is possible for the mobile robot and the astronaut to have multiple courses of actions to restore communications if it becomes disrupted. To effectively accomplish a team's mission, a human supervisor responsible for monitoring and supervising the terrestrial activities of mobile robots and astronauts in this domain needs useful decision aiding tools in order to identify productive courses of action.

Abstract:

The application of intravehicular robotic assistants (IRA) can save valuable working hours for astronauts in space stations. There are various types of IRA, such as an accompanying drone working in microgravity and a dexterous humanoid robot for collaborative operations. In either case, the ability to navigate and work along with human astronauts lays the foundation for their deployment. To address this problem, this paper proposes the framework of simultaneous astronaut accompanying and visual navigation. The framework contains a customized astronaut detector, an intravehicular navigation sys

Abstract:

Nutrition is extremely important in everyday life. And in extreme conditions, its role increases dramatically. Specific factors of a space flight have an adverse effect on the human body. One of the ways to prevent negative physiological changes is adequate nutrition to the needs of the body, ensuring the preservation of health and efficiency of astronauts performing unique scientific experiments and solving problems of national economic importance. A man developed a 16-day Russian ration because of the astronaut nutrition transition to rations from domestic products instead of the integrated

Abstract:

Astronauts in space are subject to continuous exposure to ionizing radiation. There is concern about the acute and late-occurring adverse health effects that astronauts could incur following a protracted exposure to the space radiation environment. Therefore, it is vital to consider the current tools and models used to describe and study the organic consequences of ionizing radiation exposure. It is equally important to see where these models could be improved. Historically, radiobiological models focused on how radiation damages nuclear deoxyribonucleic acid (DNA) and the role DNA repair mech

Abstract:

Homo sapiens and their predecessors evolved in the context of the boundary conditions of Earth, including a 1 g gravity and a geomagnetic field (GMF). These variables, plus others, led to complex organisms that evolved under a defined set of conditions and define how humans will respond to space flight, a circumstance that could not have been anticipated by evolution. Over the past ~60 years, space flight and living in low Earth orbit (LEO) have revealed that astronauts are impacted to varying degrees by such new environments. In addition, it has been noted that astronauts are quite heterogene

The robot weighs 30 kilograms, and consists of a torso, three identical 4-degree of freedom (DOF) arms, three end effectors, and three monocular vision system on each end effector.

In 1961, President John F. Kennedy declared that the United States would send a man to the moon and safely bring him home before the end of the decade. Astronaut Michael Collins was one of those men. He flew to the moon on the historic flight of Apollo 11 while Neil Armstrong and Buzz Aldrin walked on its surface. However, this was not supposed to be the case.Astronaut Collins was scheduled to fly on Apollo 8. While training, in 1968, he started developing symptoms of cervical myelopathy. He underwent evaluation at Wilford Hall Air Force Hospital in San Antonio and was noted to have a C5–6 dis

Abstract:

Microgravity (μG)-induced orthostatic intolerance (OI) in astronauts is characterized by a marked decrease in cardiac output (CO) in response to an orthostatic stress. Since CO is highly dependent on venous return, alterations in the resistance to venous return (RVR) may be important in contributing to OI. The RVR is directly dependent on arterial compliance (Ca), where aortic compliance (Cao) contributes up to 60% of Ca. We tested the hypothesis that μG-induced changes in Ca may represent a protective mechanism against OI. A retrospective analysis on hemodynamic data collected from astronauts

In the long term, approaches can be made and/or applied to prepare them for future space missions. This includes acknowledging the relationships individuals have to uncertainty, including productivity and sustaining cognitive aloneness (intended as a cognitive skill capable of limiting the interference of externa

Therefore, it is of great practical importance to assess the astronauts’ performance via various parameters in the cramped and weightless space station. In this paper, we proposed a calibration-free multi-view vision system for astronaut performance capture, including two modules: (1) an alternating iterative optimization of the camera pose and human pose is implemented to calibrate the extrinsic camera parameters with detected 2D keypoints.

Abstract:

Life on Earth has evolved continuously under Earth’s 1 G force and the protection of the magnetosphere. Thus, astronauts exhibit maladaptive physiological responses during space travel. Exposure to harmful cosmic radiation and weightlessness are unique conditions to the deep-space environment responsible for several spaceflight-associated risks: visual impairment, immune dysfunction, and cancer due to cosmic radiation in astronauts. The evidence thus reviewed indicates that microgravity and cosmic radiation have deleterious effects on the cardiovascular, lymphatic, and vision systems of astron
