Spacecraft Hardening: Fortifying Technology Against Solar Radiation

Radiation hardening plays a crucial role in space missions. This process enables spacecraft to be more tolerant of high levels of radiation.

Spacecraft Hardening For Solar Radiation Protection

Radiation-tolerant electronics can withstand the high radiation levels found in space and other hazardous environments, which is crucial during space missions. Electronics are made more robust through radiation hardening.

Radiation hardening creates radiation-tolerant electronics and constructs defenses against intense radiation in other non-radiation-resistant electronics. City Labs is particularly interested in radiation-tolerant technology and radiation-hardening as they develop power sources to sustain the long-term operation of microelectronic devices in distant locations.

There are some settings and circumstances where radiation exposure is extremely high. City Labs' technology must advance at the same time that science explores these risky areas of inquiry. Their ability to conduct advanced scientific research will be constrained if they cannot operate machinery under extremely high radiation levels.

Electronics that are not radioactive will be harmed by working with nuclear energy and radioactive substances. The standard technology cannot function in space due to radioactive contamination. Thus, the spacecraft must be protected from the consequences of uncharted surroundings.

Radiation-tolerant components and power sources have become the norm for spaceships and other star-bound technology. Nevertheless, they are currently trying to determine the entire range of precautions required in the future.

Electrons that can withstand radiation have been hardened and tested; if successful, radiation-hardened electronics will also be radiation-tolerant.

To safeguard GPS and weather systems, electronics must be radiation-hardened. If our electronics are not radiation-tolerant, the ionizing radiation from GCRs and other (single event effects) SEEs can obliterate even the most sophisticated of them.

Solar Radiation Testing

Radiation testing is more important than ever as NASA investigates the solar system. The Radiation Effects Facility, located at NASA's Goddard Space Flight Center in Greenbelt, Maryland, aids in the inspection of the hardware that enables NASA's exploration of the Moon, the Sun, and our solar system, ranging from missions designed to understand the origins of the universe to the much closer-to-home Artemis program's trip to the Moon.

According to Megan Casey, an aerospace engineer with the Radiation Effects and Analysis Group at Goddard, they can guarantee that people, electronics, spacecraft, and sensors - whatever we are sending into space - can survive in the environment we are putting it in, NASA reported.

Engineers meticulously test and choose elements tailored to each spacecraft's destination since the specific environmental conditions a spacecraft will experience depend on where it is going. For instance, the radiation belts are two doughnut-shaped bands formed by the Earth's magnetic field's capture of particle swarms.

There are radiation belts on other planets, such as Jupiter, whose straps are 10,000 times more powerful than Earth's. The solar wind, also known as the wash of solar particles, is typically harsher the closer it is to the Sun. Additionally, galactic cosmic rays - particle pieces from far exploding stars - can be found everywhere.

Timing also plays a role. The Sun naturally oscillates between high and low activity for 11 years. Cosmic rays can quickly enter the solar system because of the Sun's magnetic field's relative calm during solar minimum. On the other hand, frequent solar flares during the solar maximum saturate space with high-energy particles.

According to Casey, they describe the environment in orbit for mission designers based on where they are going, and then they return with their instrument plans and inquire if the parts will survive. The response is either yes, no, or I'm not sure. If they are unsure, they conduct more testing. Casey said their work consists primarily of doing that.

Goddard's radiation center and other labs across the nation are outfitted to simulate the full spectrum of space radiation, from the solar wind's continual annoyance to the radiation belts' scorching heat and the terrible strikes of solar flares and cosmic rays.
