THE  CORE  CHALLENGE

The space environment harbours life-threatening hazards to space travel. Amongst these, space radiation and micrometeoroids. 

Radiation shielding, is essential to reduce the risk of cancer and other related health hazards, in order to protect and preserve life during space travel and exploration. Furthermore, radiation shielding is essential, to preserve the integrity of instrumentation tools necessary for life support and scientific exploration in lunar, interplanetary environments and space.

RADIATION  SOURCES

Space radiation is mainly composed of subatomic particles such as electrons and protons, solar particle events (SPEs), and galactic cosmic radiation (GCR). Additional hazardous radiation comes from neutrons and gamma rays (γ-rays) produced via nuclear collisions and x-rays arising from Coulomb interactions. 

SPEs contain a very high number (per unit time) of high-energy charged particles originating from the Sun either via a solar- flare site or by shock waves associated with coronal mass ejections. 

GCR on the other hand, consists of high-energy charged particles from outer space sources like the supernovae of massive stars and active galactic nuclei. GCR strikes the Moon, Mars, asteroids, and spacecraft from all directions and is always present as background radiation. GCR particles are fundamentally positively charged and interact with matter primarily via Coulomb interactions with the negative electrons and positive nuclei in the materials. They also, to a lesser extent, interact with materials via collisions with their atomic nuclei. GCR particles represent the most significant and challenging space radiation to attenuate. 

Neutrons are produced as secondary radiation, when GCR and SPEs interact with the walls and contents of space structures (vehicles, landers, habitats, or spacesuits). Secondary neutrons are also produced when the GCR and SPE interact with the surfaces of Mars, the moon, and asteroids.

OUR  SOLUTIONS      

Our nanoadditives for space coatings and composite material systems are designed to enable mechanical reinforcement, reduced weight (for fuel conservation and extended flight range), heat- and radiation-resistance for extensive space travel in variable degrees of hazardous and corrosive environments.
