Experiment OverviewThe 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.

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.
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 ApplicationsWith 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.
