When the ดาวน์โหลด slotxo European Space Agency (ESA) designed spacecraft to fly closer to the Sun than any other probe in history, it faced a major problem: how to protect it from intense heat and radiation.The mission in conjunction with NASA Solar Orbiter was launched in February 2020 and just emerged from the first post-Sun transmission. It must be able to withstand temperatures hot enough to melt lead, as well as 13 times the radiation reaching the Earth's surface.The agency initially looked for conventional solutions using metal and carbon fiber. But that's not good enough,

ESA's project manager Cesar Garcia Marirrodriga for Solar Orbiter told CNN Business, but the agency found the answer in content dating back to the Stone Age.Ancient pigmentsAfter the ESA issued an invitation for a resolution, ENBIO was contacted by an Irish biotech company. Developed techniques for applying synthetic bone coatings to bone and dental implants to make it easier for the patient's body to accept them. As the technique helps to reduce weight and prevent problems such as peeling, ENBIO thinks it may be helpful for Solar Orbiter's titanium substrate.

But the synthetic bone is light in color, and tests show that it darkens after prolonged exposure to sunlight, changing the amount of heat it absorbs and reflects back. The black coating means that its properties are constant for all missions, absorbing the sun's energy as heat and then dropping that into space.I tried to paint the bone powder to make it black. But it didn't work either, ďż˝recalled ENBIO founder John O'Donoghue.Instead, he started looking for natural black bone powder. "I remember reading as a kid that in cave art people use charcoal and in some cases [burned] animal bones because the end of them is like colored pencils and they can be painted on the wall," he said.After O'Donoghue supplied the burnt animal bone powder, the ESA found it ideal for the solar mission.

Besides being black, nothing flammable remains in the material, so when it heats it doesn't release any gas that could damage the spacecraft, explains Garcia Marirrodriga.The resulting coating, called SolarBlack, covers about a fifth of the Solar Orbiter's surface area and allows the most sensitive parts to operate at room temperature while absorbing heat up to 1,000 degrees Fahrenheit. ENBIO partnered with Airbus (EADSF). Developed SolarWhite, a white coating that covers other parts of satellites where sunlight needs to reflect rather than absorb.

Aim for area

O'Donoghue's interest in coating technology began while studying biomedical engineering at Trinity College in Dublin.He founded ENBIO in 2006 and in 2015 the company opened an industrial coatings worth ďż˝ 1.5 million ($ 1.8 million). In Clonmel, about 100 miles southwest of Dublin, Solar Orbiter grossed millions of euros for the company, according to O'Donoghue, and ESA has used SolarBlack for other missions.O'Donoghue said coatings and coatings can find applications in the automotive, metalworking, heating and power industries, and more, but the current focus is beyond this world. "We aim for the space sector because we feel that if we reach the top of the pyramid and [Well done there] the rest of the industry will accept more,

he said.Although the main mission will not begin until November. But in July, the Solar Orbiter sent back the closest image of the Sun.Over the next few years, the 1.5 billion euro ($ 1.8 billion) mission will use the gravity of Earth and Venus to make a catapult near the Sun, finally able to pass close to the star in Mercury's orbit. As much as possible ďż˝The goal is to truly understand physics how the sun creates and controls the heliosphere. (The area around the sun) and why does solar activity change over time, ďż˝Garcia Marirodrica said.
