Bioastronautics Overview

Principles

Definition

Bioastronautics is an interdisciplinary research field dedicated to investigating the physiological, psychological, and ecological effects of the space environment on biological systems, with a primary focus on human adaptation and performance, and developing the biological and life support systems essential for sustaining life and enabling exploration beyond Earth.

Systemic Microgravity Health era

Philip M. Gallagher [1] is associated with Wake Forest University [3] and the University of Missouri–Kansas City [4] during this era. The paper Prolonged space flight-induced alterations in the structure and function of human skeletal muscle fibres [7] details how such alterations affect skeletal muscle structure and function, informing the development of countermeasures and monitoring strategies for this era. Scott Trappe [2] is associated with Karolinska Institutet [5] and the University of Auckland [6] during this era. Together with Gallagher, Trappe contributed to Prolonged space flight-induced alterations in the structure and function of human skeletal muscle fibres [7], providing mechanistic insights into muscle adaptation to unloading that supported system-wide health strategies for the era.

Radiation and Multi-Omics Integration era

Scott M. Smith[1], associated with the University of Rochester[3] and Wayne State University[4] during the Radiation and Multi-Omics Integration era, is highlighted for advancing space biology through multi-omics perspectives. His key contributions in this era include the 2020 Comprehensive Multi-omics Analysis Reveals Mitochondrial Stress as a Central Biological Hub for Spaceflight Impact[7], the 2015 Bone metabolism and renal stone risk during International Space Station missions[8], and the 2019 Resistive exercise in astronauts on prolonged spaceflights provides partial protection against spaceflight-induced bone loss[9], which collectively illuminate mitochondrial stress as a mechanistic hub and inform countermeasures. Sara R. Zwart[2], with affiliations at The University of Texas Medical Branch at Galveston[5] and The University of Texas Health Science Center at Houston[6], embodies the integrative role in this era. Her contributions include guiding pharmacological strategies for returning to gravity via Multi-omic, Single-Cell, and Biochemical Profiles of Astronauts[10], complementing the 2020 Comprehensive Multi-omics Analysis Reveals Mitochondrial Stress as a Central Biological Hub for Spaceflight Impact[7] and the 2015 Bone metabolism and renal stone risk during International Space Station missions[8], collectively shaping biomarker-driven testing paradigms and mission countermeasures.
