Brief Summary

The Anomalous Long Term Effects in Astronauts' Central Nervous System - Shield (ALTEA-Shield) investigation provides an assessment of the radiation environment inside the International Space Station (ISS). The goal is to better understand the interaction between cosmic rays and brain functions. Since radiation exposure in space is one of the greatest risks to human health, a better understanding and characterization of the shielding capability of different materials is needed in order to enable future, long term human exploration.

    Experiment Description

    Research Overview

    • Astronauts in orbit are exposed to cosmic radiation that is of sufficient frequency and intensity to cause effects on the central nervous system. Radiation exposure represents one of the greatest risks to humans traveling on exploration missions beyond low Earth orbit (LEO).


    • ALTEA-Shield is part of the ALTEA program, a multidisciplinary research project which aims at obtaining a better understanding of the light flash phenomenon, and more generally the interaction between cosmic rays and brain functions. Interactions between ionizing radiation in space and brain functions, and the related risk assessments, are among the major concerns when programming long permanence in space.


    • The Anomalous Long Term Effects in Astronauts' Central Nervous System - Shield (ALTEA-Shield) experiment, developed by the Italian Space Agency (ASI), will measure the particle flux in the U.S. Laboratory on the International Space Station (ISS), being able to discriminate the type of particles, to measure their trajectories and the delivered energies.

    Applications

    Space Applications

    It is vital for us to understand and monitor the radiation environment around our planet in order to safeguard our astronauts during their missions in low-Earth orbit. This is even more important for future human exploration missions outside of low-Earth orbit, such as to the Moon and Mars, where there is no longer any protective shielding coming from Earth’s magnetic field and there are greater problems posed by radiation in particular by events such as solar flares.  The development of better shielding materials is a necessity for making improvements in future spacecraft and satellite design and essential mission planning. In addition to the positive effect this will have on human exploration missions, this will also help to extend the life of satellites in orbit by reducing the effect caused by solar and galactic radiation, which can damage satellite electronics.

    Earth Applications

    With life on Earth becoming increasingly dependent on satellite communications and data, developing better shielding materials to extend the life of satellites will have a positive effect on communications and data services on earth. On Earth as well cosmic rays which get through Earth’s atmosphere can cause errors in integrated circuits such as data corruption in memory devices and incorrect CPU performance. New shielding materials could find their way into shielding applications for such electronic circuitry which is becoming more susceptible as it reduces in size. This can affect many industries from the automobile industry to aerospace to navigation.  This type of research is also providing us on Earth with a more detailed picture of the radiation environment in low-Earth orbit which can help us better understand how our planet works. By comparing this data with data on Earth it could help to determine the impact that Earth’s radiation environment may have on climatology and thus help to improve climate models.
