Boron Nitride Ceramic - Space Radiation Shielding

The vision of sending humans to space has captured many people's attention, from engineers to scientists. Success in space missions could open a new era for developments. Before achieving the possible benefits of traveling to space, some prominent issues regarding the journey have to be prioritized. The most significant issue is space radiation that astronauts face in space journeys.

What is space radiation?
Space radiation comprises atoms. Electrons of those atoms have been exposed away as it accelerated in interstellar space to speed, approaching the speed of light. Only the nucleus of the atom remains constant.

Effects of space radiation:
Radiation occurs when cosmic particles transport energy from one being to another. Energy particles can be dangerous to humans because they pass right through the skin causing serious health issues, including cardiac problems, vomiting, and damaging cells or DNA along the way. The exposure also causes an increase in cancer risks. It can damage the central nervous system, manifesting itself as altered cognitive function, reduced motor function, and behavioral changes.

Boron Nitride as Shielding Agent
To prevent harmful radiation, scientists and engineers are discovering new ways to protect the spacecraft by covering the spacecraft with definite materials - boron nitride ceramic - that will obstruct radiation.

A precise type of shielding matter that scientists are showing interest in is "hydrogenated boron nitride nanotubes". BNNTs give the chance for success in the fight against radiation. Furthermore, it is believed that BNNTs are valuable due to their chemical structures, making them an ideal material to use outside of the spacecraft and also on the astronaut's spacesuits. According to professionals, BNNTs exhibit exceedingly high strength, durability and flexibility, proving itself as a foremost candidate for shielding.

Shielding the spacecraft involves using construction materials to prevent radiation from hitting the spacecraft and astronauts. To craft such protection is not only important to the astronauts completing their space journeys but if it works more effectively, a landing on other planets will be possible for the prosperity of humanity.

The prime advantage of radiation shielding is to prevent ions hitting the spacecraft. The health effects of continuous exposure to space radiation are considerably reduced for galactic rays and solar particle events. To safely travel in space, scientists and engineers collaborate in constructing a reasonable solution for blocking radiation by one specific type of shielding, Boron Nitride Nanotubes (BNNTs).

Boron Nitride Nanotubes- AN EFFECTING SHIELDING
A Boron nitride nanotube is a tubular molecule filled with boron, nitrogen and hydrogen is infused between them. These elements are ideal for their low number of protons, a characteristic related to non-permeability. BNNTs provide an effective shield due to the boron; it has a "large capture cross-section, making it effective at capturing harmful neutrons."

As per scientists, boron nitride is strong-even at high heat-meaning that it's great for structure". The boron-nitrogen bonds are asymmetric, which means that the electrons density is toward the nitrogen bond side. This causes partial ionic structure, establishing a gap between inner electron bands and the valence.

The semiconductor gap stops the radiation and makes BNNTs effective shielding. It is believed that this advanced technology can be the solution to the radiation problem. It can be manufactured to be placed almost anywhere on the spaceship; this means the astronauts have extra protection on a spacewalk mission.

Conclusion:
The radiation penetrates through spacecraft, harming astronauts' health. Astronauts cannot be able to complete space missions with severe health problems. The BNNT chemical structure allows strong, lightweight, and durable material that blocks particles from passing through the craft and space suits. This new technology is versatile, as it will help the astronauts by using it. Due to the BNNT's structure, it is believed that it is the answer to the radiation problem that astronauts face.

EOS Data Analytics to launch satellite with Dragonfly Multispectral Imagers in 2022
Los Angeles CA (SPX) Oct 27, 2020
EOS Data Analytics has announced the conclusion of an agreement with Dragonfly Aerospace for the delivery of two HR-250 high-performance multispectral imagers. A satellite equipped with the Dragonfly imagers will be launched into Low Earth Orbit (LEO) early in 2022. The side-by-side payloads will allow for the creation of wide swath images in 7 spectral bands at close to 1m resolution. Multispectral images are critical for tracking environmental changes. They allow the monitoring of selected areas ... read more
