LIFE IN SPACE: AN UNEXPECTED THOUGHTFUL MODEL

SPACE BIOMEDICINE LABORATORY

Gravity has constantly influenced both physical and biological phenomena throughout Earth’s history. The gravitational field has played a major role in shaping evolution when life moved from water to land. However, gravity may influence in a more deep and subtle fashion the way the cells behave and build themselves. Cells may indeed ‘sense’ changes in the microgravity field through:

  • (1) an indirect mechanism (mainly based on the modification of physical properties of their microenvironment);
  • (b) the development of specialized structures for the mechanical perception and transduction of gravitational forces (like the cytoskeleton);
  • (c) changes in the dynamics of enzymes kinetics or protein network self-assembly.

It is worth noting that the latter two processes are dramatically affected by non-equilibrium dynamics. Non-linear dynamical processes far from equilibrium involve an appropriate combination of reaction and diffusion, and the pattern arising from those interactions are tightly influenced by even minimal changes in reactant concentrations or modification in the strength of the morphogenetic field. Processes of this kind are called dissipative structures, given that a consumption of energy is required to drive and maintain the system far from equilibrium. That prerequisite is needed in order to allow the system to promptly change its configuration, according to the system’s needs. In turn, the dissipative energy provides the thermodynamic driving force for the self-organization processes. Accordingly to some preliminary results, gravity seems to influence non-equilibrium processes (like the cytoskeleton reorganization), acting as an ‘inescapable’ constraint that obliges living beings to adopt only a few configurations among many others. By ‘removing’ the gravitational field, living structures are free to recover more degrees of freedom, thus acquiring new phenotypes and new functions/properties.

These data raise several crucial questions. Some of these entail fundamentals of theoretical biology, as they question the gene-centric paradigm, according to which biological behavior can be explained by solely genetic mechanisms. Indeed, influence of physical cues in biology (and, in particular, on gene expression) is still now largely overlooked. This is why it has been argued that the ultimate reason for human space exploration is precisely to enable us to discover ourselves. Undoubtedly, the microgravity space-field presents an unlimited horizon for investigation and discovery. Controlled studies conducted in microgravity can advance our knowledge, providing amazing insights into the biological mechanism underlying physiology as well as many relevant diseases, like cancer. Thereby, space-based investigations may serve as a novel paradigm for innovation in basic and applied science.

Phase Transitions Processes

Research Activities

Space biomedicine and biotechnology studies are chiefly developed according to the following areas of interest:

1. Theoretical Studies and Basic Biology

The theoretical foundations that allow us to understand how gravity can significantly influence numerous processes and functions of living structures are still essentially unknown. The interactions occur according to different mechanisms and principles in relation to the level of observation – organism as a whole, organs, cells – and the development of an integrated project. These themes require, in particular, the possibility of studying critical hubs and pathways (like the endocrine control) in 3D-models, properly integrated with microfluidic devices and real-time imaging, allowing for extended periods of investigation. Furthermore, a specific area of investigation is related to the discovery of useful molecules (e.g., antibiotics, anti-inflammatories, MABs, protein crystals) produced by unicellular organisms in weightlessness. The lab will develop systematic access solutions to space laboratories currently available (e.g., ISS) and in the near future (e.g., AXIOM, SpaceRider) and shall dedicate facilities for research, manufacturing, and testing in space. Other areas of interest include:
  • Specification and spatialization of infrastructure for innovative molecules generation.
  • Study of natural molecules to counteract effects like radiation, insulin resistance, hormonal alterations, and oxidative effects.

2. Personalized Astronaut Medicine

The need to develop wearable sensors and systems capable of detecting a useful set of physiological parameters is critical for human space exploration and Moon colonization. Key areas of interest include:
  • Investigating sensor solutions for predictive health pattern interpretation
  • Spatialization and ergonomics studies in VR
  • Development of augmented reality applications to guide astronauts
  • Ground validation on patient cohorts with space-like dysfunctions
Long-term mission support strategies include identifying physiological needs and solutions for effects on bone systems, muscle stimulation, and genome-impacting variables like magnetic field transitions. AI-based diagnostic platforms play a crucial role in these innovations.

3. Food for Space

Ensuring proper astronaut nutrition is imperative. Key objectives:
  • Define astronauts’ metabolic fingerprints in altered gravity environments.
  • Support metabolic development using nutraceutical tools.
  • Design systems for in situ food production in microgravity or lunar/Martian environments.
  • Study of plants and water systems for purification and decontamination.
Understanding macro and micronutrient impacts on nutrition and physiology is vital for long-term missions.

Technology Transfer Table

OBJECTIVES

The main objective of the initiative is to pool the capabilities and potential of the partners, starting an activity capable of self-sustaining, generating scientific and economic results in the context of the New Space Economy.

Technology Transfer Table

The laboratory’s activities will be enhanced through the creation of a Technology Transfer Table, involving stakeholders and research institutions interested in the terrestrial applications of the results achieved in space.
A first operational opportunity will focus on Food for Space, with a roundtable coordinated by the Ministry of Agriculture, involving the Space Biomed Laboratory, ASI, and agri-food companies.
The goal is to valorize patents and industrial applications, potentially leading to spin-offs and startups.

Educational

The Laboratory plans to launch an educational program in collaboration with La Sapienza University, TAS-Italia, and others, including the Italian Space Agency and the Centre for AeroSpace Research (CRAS). This initiative includes:

  • Advanced training courses, masters, and teachings integrated into Medicine and Space Engineering degrees.
  • Preparatory training for highly skilled personnel for public and private sector roles.
  • Partnerships with Italian and international institutions for advanced training.

To support these efforts, a dedicated website and communication strategies will be established.

Deliverables

Once operational, the collaboration will market medical and biological test services for ground and orbital experiments, targeting industries, space agencies, and pharmaceutical companies. A partner may be designated as a Service Provider to represent the team and expand partnerships with other entities.

Current Research Programs

Ongoing programs include:

  • OVOSPACE: Evaluation of endocrine function in microgravity, supported by ISS investigations.
  • ORION: Pharmacological modulation of ovarian alterations induced by microgravity, also supported by ISS research.
  • GRAVI-HEART: Evaluation of markers of muscle damage (heart-muscle) in hypoxia/microgravity and development of salivary analysis sensors.
  • MONSTRE: PNRR-PE15 – Spoke 9: Analysis of muscle damage markers and pathways, part of the National PNRR program.

The Sapienza team has acquired – since 2005 – a role of national pre-eminence for studies conducted in microgravity.
The laboratory owns a Random Positioning Machine – through which it carries out experiments in microgravity – and has participated/is participating in space missions on the International Space Station. The focus is to investigate the functional behavior, morphological characterization, and gene/protein expression during microgravity. A patent, related to the discovery of antibiotics produced in microgravity, is currently ongoing.

THALES ALENIA SPACE

The TASI team that will support the Laboratory has great systems and specialist know-how in the field of human space missions and is interested in continuing its R&D activity in support of the development of its products
(e.g. SPACE HOME, Space Rider), in the field of inhabited modules, and participation in the ASI/ESA/NASA and Commercial programs (e.g. AXIOM). Furthermore, there is great interest in supporting technologies for long-duration missions, requiring the implementation of new engineering concepts related to life science, such as transfer pods and life support control systems that are extremely more complicated and complex than current systems.

The main themes related to the activities planned for the Laboratory are:

  • Development of greenhouses and systems for food supply in orbit, in transit and/or on the lunar/Martian surface.
  • Design and implementation of medical payloads, sensors, and human physiology experiments on space stations.
  • Integrability of wearable systems/sensors in space structures for radiation protection.
