There is Finally a Computer that Can Survive on Venus

How amazing is that? There is finally a computer that can survive on Venus and help scientists explore the surface of this planet. It is amazing that they were finally able to develop something that will last for a longer period of time that will give them the ability to explore this planet more deeply. It probably won’t be so significant but will definitely help us see something significant from this planet. If you are interested to find out more about it, make sure to keep reading the article to find out more valuable information.

There is a reason why the Red Planet is being explored more than Venus, although it is farther away from Earth. Venus is one of the most unfortunate places in the Solar System. Lowering the dense atmosphere and the acid rain are not such a problem. In fact, real problems only arise when landing on the surface of this 'hell', where temperatures are up to 500 ° C and the pressure is 90 times higher than the Earth's surface pressure. It seems that NASA has tackled this problem, which has not been resolved for decades.

On the Venus planet, the human spacecraft has not even attempted to land since 1985. The survival record was carried out by Venus 13, a Russian probe that lasted for 127 minutes. It successfully sent the first incredible photos of the surface of Venus in color to the Earth. The probe was a tremendous success for the time, especially since the first estimates were that it would only last for 32 minutes before this inhospitable planet was ducked, crushed, and split into the last pieces.

It has been many years since the last visit to Venus was made, many new modern materials have been developed, more resilient than ever before. Similar is true for computers and optics. But computers that make up the heart of silicon fragments are not able to work when temperatures exceed a certain level. Silicon chips at 250 ° C cease to be semiconductors and things just do not work again. The Russians tried to skip this huge problem at least temporarily - using massive hermetically sealed chambers on the probes, which would be known and cooled to -10 ° C before they were allowed to penetrate the Venus orbit through a dense atmosphere. But probes could still transmit data only minutes, let alone hours or days.

In the past few years, things have begun to develop better. The electronics based on silicon carbide (SiC) have begun to ripen, and special interest in technology has been shown by heavy industries and, of course, by the military. The reason for this is simple - SiC can withstand high voltages and temperatures, making it an excellent choice and for making a probe that would last for longer on the surface of Venus.

NASA's Glenn Research Center has recently announced great success in this field. The electronics they developed successfully tested in the tests for as long as three weeks (521 hours) in the conditions prevailing on Venus, without the help of a special hermetic chamber and a cooling system. However, there is a latch. The tested circuit is actually extremely simple and definitely not an indication of everything that can be done.

Researchers say it is a newly developed piece of electronics that can withstand this all at the level of the early 70's according to Moore's chip complexity law. However, it is an important step forward

"With further maturing technology, SiC IC electronics could drastically improve the design of probes intended for the exploration of Venus. Basically, it would allow the longer duration of missions, which could be more comprehensive, "concludes the research team working on the project. Details of the research are available in published work.

Soviet research from Venus from 1961 to 1985 showed that the survival of the electronics of the probe is still only part of the story. Tools that need to be done for drilling and surface analysis must also be able to survive 'hellish' conditions so that the missions make sense. But, as noted earlier, today's engineers are greatly assisted by the fact that in these decades since the last landing on Venus, many advanced materials and systems have been developed ready for such an undertaking.

Developing a probe that would explicitly explore the planet closest to Earth is a step from the realization. Until then, the Red Planet will still have priority, with its own set of problems. This whole thing is very impressive for both scientists and us who are eagerly waiting to find out more and be able to see photos of the planet that has long been talked about. Finally, we will all have a chance to see something like that.
