Dynamic analysis and motion control of spinning tether system during its Earth to Mars flight

Космические аппараты и технологии, 2021
The dynamic analysis and motion control of a spinning tether system for an interplanetary mission to Mars is considered. The space system consists of two spacecraft connected by a tether with thrusts to control its movement.

Limited Effect of 60-Days Strict Head Down Tilt Bed Rest on Vascular Aging

Frontiers in Physiology, 2021
BackgroundCardiovascular risk may be increased in astronauts after long term space flights based on biomarkers indicating premature vascular aging. We tested the hypothesis that 60 days of strict 6° head down tilt bed rest (HDTBR), an established space ...

History of Artificial Gravity [PDF]

, 2007
This chapter reviews the past and current projects on artificial gravity during space missions. The idea of a rotating wheel-like space station providing artificial gravity goes back in the writings of Tsiolkovsky, Noordung, and Wernher von Braun. Its most famous fictional representation is in the film 2001: A Space Odyssey, which also depicts spin ...

Venous and Arterial Responses to Partial Gravity

Frontiers in Physiology, 2020
Introduction: Chronic exposure to the weightlessness-induced cephalad fluid shift is hypothesized to be a primary contributor to the development of spaceflight-associated neuro-ocular syndrome (SANS) and may be associated with an increased risk of venous
