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

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.

Ever wonder how an astronaut’s mass is measured in space? Of course, a weight scale is of no use, because the astronaut and the scale are in free fall. Measuring the period of a spring mass oscillator is one way to measure mass. In this article, we will demonstrate a method to measure mass using a smartphone, a rubber band, and an app called phyphox.

In the zero-gravity environment of space, astronauts experience significant physiological and biochemical changes. Upon returning to Earth, they undergo another transformation and must participate in rehabilitation to readapt to Earth's gravity. Notably, female astronauts of the European Space Agency and NASA are currently prohibited from becoming pregnant during their missions. However, there is no such prohibition for pregnancy during commercial space missions. for a mother-astronaut, the physiological changes are multi-staged and complex. These changes encompass various phases: during pregn

This article uses a philosophical hermeneutic perspective to present a reading of selected astronaut space selfies by drawing on ideas of Michel Serres, Paul Virilio, Hannah Arendt, Bonnie Mann, Joanna Zylinska, Nicholas Mirzoeff, and W. J. T. Mitchell. The image of the astronaut is unpacked as a visual apocalyptic trope that embodies collective dreams of going beyond Earth in post-Earth projections. Michel Serres distinguished between two regimes of pollution, namely “hard pollution” and “soft pollution.” The author uses Serres's distinction between hard and soft pollution to investigate the

This paper proposes a full-size and free-flying humanoid robot named Taikobot that aims to assist astronauts in a space station and maintain spacecrafts between human visits. Taikobot adopts a compact and lightweight (∼25 kg) design to work in microgravity, which also reduces launch costs and improves safety during human–robot collaboration. Taikobot’s anthropomorphic dual arm system and zero-g legs allow it to share a set of intravehicular human–machine interfaces. Unlike ground-walking robots, Taikobot maneuvers in a novel push–flight–park (PFP) strategy as an equivalent astronaut in a space

A space suit is a special type of suit worn by an astronaut during an expedition on the space. In order to keep the astronauts alive in the critical conditions of the outer space, these are worn by them. As the environment on the space is extreme from all corners, therefore it is designed to suit the astronauts as they avail the same in Earth’s conditions. Any space suit is composed of many layers materials starting from three to fourteen in number. Each layer has its own function for the survival of the astronauts on the space.

The use of mobile robots for assisting astronauts in extravehicular activities could be an effective option for improving mission productivity and crew safety. It is thus critical that these robots follow the astronaut and maintain a stable distance to provide personalized and timely assistance. However, most extraterrestrial bodies exhibit rugged terrain that can impede a robot’s movements. As such, a novel predictive-guide following strategy is proposed to improve the stability of astronaut–robot distance in obstructive environments.

In order to ensure that the astronauts in the cabin can obtain a continuous and enough oxygen supply, it is necessary to carry out real-time condition monitoring and fault diagnosis of the EOGS. This paper deals with condition monitoring and fault diagnosis of the EOGS.

The question of the composition of exercise protocols for use by astronauts in microgravity is unresolved. Based on our knowledge of physical working requirements for astronauts during intra- and extravehicular activity and on the findings from bed-rest studies that utilized exercise training as a countermeasure for the reduction of aerobic power, deterioration of muscular strength and endurance, decrements in mood and cognitive performance, and possibly for bone loss, two exercise protocols are proposed.

The physiological mechanisms for releasing and resolving gravitational ischemia in the brain, and their susceptibility to malfunction, may play an important role in a variety of neurological illnesses. An astronaut on a space walk in a micro-gravity environment may be susceptible to neuro-ocular symptoms associated with unopposed gravity-resistance mechanisms for partially preventing gravitational ischemia in the brain, and for attenuating its impact—mechanisms which may be required for normal brain physiology on Earth.
