NASA develops computer chips that operate on Venus with 90 times the pressure of the earth and surface temperatures above 460 degrees

Venus, which is the planet whose size and average density resemble the earth most in the solar system, is sometimes expressed as "sister planet of the earth", but the atmospheric pressure is 90 times that of the earth, and the surface temperature is over 460 degrees It is wrapped in the harsh environment that there is also. Successful landing of Venus was based on the Soviet Venus Exploration Plan "Venera plan"It is the state that it can not operate the equipment for a long time under harsh environments even after landing. Meanwhile, NASA's Glenn Research Center succeeded in developing computer chips that can operate for hundreds of hours to several weeks even in environments like Venus.

The Venus 13 of the Soviet Union, which landed on Venus in 1981, continued to operate for 127 minutes on the surface of Venus and succeeded in sending color photographs of Venus' ground surface for the first time to mankind. Originally Veneta's activity limit under the environment of Venus was designed to be 32 minutes, but it continued activity three times as assumed, which is also the longest activity record of Venus of mankind.

Precision instruments that were installed in the probe of the Venera plan were protected by a pressure vessel equipped with a huge and heavy cooling system, but the Glenn Research Center was able to detect the number of precision instruments without a cooling system or pressure vessel We have announced that we have developed a computer chip that operates days to weeks.

Silicon carbide (SiC), which is being developed in recent years, is a semiconductor thought to be able to withstand in harsh environments such as Venus, but Glenn Research Center is a 3 mm × 3 mm Developed SiC chip. SiC chips and circuits are housed in wires made of nickel alloy and test machines capable of reproducing the planetary environment of the solar system "GEERTested the operation in the environment of Venus, it proved that it worked normally for 521 hours (21.7 days).


"This is the first demonstration of computer chips to operate without pressure vessels and cooling systems in an environment like Venus, and if the technology matures, the SiC chip will be on a long Venusian surface I will make the mission possible ". Although the surface search of Venus still has a technically difficult part, the result of the research at Glenn Research Center moves around the surface of VenusSearch RoverIt is expected that it will be completed by 2023.
