In this paper, we present an approach for supporting spatial awareness in an intelligent tutoring system, the purpose of which is to train astronauts to operating tasks of a telemanipulator. Our aim is to propose recommendations regarding knowledge structures and cognitive strategies relevant in this context. The spatial awareness is supported through efficient use of animations presenting diff...

Occupational radiation exposure from the space environment may increase cancer morbidity or mortality risk in astronauts. This risk may be influenced by other space fl ight factors including microgravity and e nvironmental contaminants. A Mars mission will not be fe asible unless improved shielding is developed or transit time is decreased. – Human Research Program Requirements Document, HRP-47...

A Canadian physician-engineer who had difficulty finding suitable work in Canada is now employed by an American company that is helping develop the medical systems that will serve astronauts. Dr. Douglas Hamilton thinks research in space medicine will have applications on earth.

Europeans will soon send inhabited missions into space with the Ariane 5 launcher and spaceshuttle Hermes combination. In case of an incident at launch, either on the pad or up to some speed after launch, it is proposed toeject the flightcrew tosafety on individualejectorseats. The risks which would be confronted by the astronauts

This review of astronaut extravehicular activity (EVA) and the details of American and Soviet/Russian spacesuit design focuses on design recommendations to enhance astronaut safety and effectiveness. Innovative spacesuit design is essential, given the challenges of future exploration-class missions in which astronauts will be called upon to perform increasingly complex and physically demanding ...

BACKGROUND AND PURPOSE We investigated cerebral blood flow regulation in astronauts before and after flights. We hypothesized that autoregulation would be different before flight and after flight between nonfinishers and the finishers of a stand test. METHODS Twenty-seven astronauts from shuttle missions lasting 8 to 16 days underwent a 10-minute stand test: 10 days before flight, 1 to 2 hour...

(Cell Reports 33, 108458-1–108458-7.e1–e3; December 8, 2020) In the originally published version of this paper, Figure 1A contained header labels for Space and Ground twins that were switched in final editing. The figure has been corrected now appears with paper online. authors regret error, these changes have no effect on rest data manuscript. addition, following author names corrected, their ...
