A second space age spanning omics, platforms and medicine across orbits

Christopher E Mason et al. Nature. 2024 Aug.

Abstract

The recent acceleration of commercial, private and multi-national spaceflight has created an unprecedented level of activity in low Earth orbit, concomitant with the largest-ever number of crewed missions entering space and preparations for exploration-class (lasting longer than one year) missions. Such rapid advancement into space from many new companies, countries and space-related entities has enabled a 'second space age'. This era is also poised to leverage, for the first time, modern tools and methods of molecular biology and precision medicine, thus enabling precision aerospace medicine for the crews. The applications of these biomedical technologies and algorithms are diverse, and encompass multi-omic, single-cell and spatial biology tools to investigate human and microbial responses to spaceflight. Additionally, they extend to the development of new imaging techniques, real-time cognitive assessments, physiological monitoring and personalized risk profiles tailored for astronauts. Furthermore, these technologies enable advancements in pharmacogenomics, as well as the identification of novel spaceflight biomarkers and the development of corresponding countermeasures. In this Perspective, we highlight some of the recent biomedical research from the National Aeronautics and Space Administration, Japan Aerospace Exploration Agency, European Space Agency and other space agencies, and detail the entrance of the commercial spaceflight sector (including SpaceX, Blue Origin, Axiom and Sierra Space) into aerospace medicine and space biology, the first aerospace medicine biobank, and various upcoming missions that will utilize these tools to ensure a permanent human presence beyond low Earth orbit, venturing out to other planets and moons.

(inset) The launches that defined the first space age, from 1957 to 2022, broken down by the country of origin. (Main) The exponential increase in launches marks the Second Space Age, driven more by commercial launches. The number of launches (y-axis) per year (x-axis) is plotted with the color annotated as the United States (blue), Union of Soviet Socialist Republics (USSR)/Russia (purple), China (red), and other countries (green).

The effective accumulated radiation dose is provided in millisieverts (mSv). The low linear energy transfer (LET) radiation (or terrestrial radiation) is denoted by the green bars. The radiation levels experienced during the Inspiration4 mission and Scott Kelly year-long mission (NASA’s Twins Study) are indicated by orange bars. The estimated radiation dose of a 3-year future mission to Mars is depicted by a red bar. All other high LET radiation doses are indicated by the blue bars.

(b) Extra-lunar orbital trajectory that would approach the Lagrange point 1 (L1) closer to the sun and up to 1.54M km from the Earth (center blue diamond). The moon’s orbit is shown in dotted lines around the Earth. (c) The orbital trajectory for a three-planet mission in 2033 that would flyby Mars twice and also Venus (flyby) within about 18 months. The launch dates and approximate orbital timings (left) are shown around the planetary orbits (dotted line circles) and the flight path (yellow line). The sun is shown in the middle of the figure.

      The SpaceX Inspiration4 mission enabled state-of-the-art, single-cell multi-omics analysis of four astronauts, revealing that spaceflight-induced changes in gene expression, chromatin accessibility, and immune cell proportions, particularly in non-classical monocytes and NK cells, largely revert to normal within a few months post-flight, providing crucial data for future space missions and countermeasure development.
