NASA Designs New Venus Rover

Beijing time August 28 news, according to foreign media reports, Venus is the hell of the solar system: terrible high pressure, strong winds, and strong acidic clouds. This harsh environment has determined that the probes that go to the planet to conduct inspections are generally only a few hours of life. Now, NASA is planning to launch an innovative detector to Venus, which will be able to use the wind of Venus' surface to roam around and conduct inspections.

NASA is contemplating sending a new concept rover to Venus. According to the design, it can use very little energy and survive at extremely high temperatures.

The envisaged three-wheeled rover is about 7 meters high. Most of the time, it will stop at the site and carry out investigations. From time to time, it will move some distances and continue to work in a new place.

Venus has the harshest and most terrible environment in the solar system. Venus is covered by a super thick atmosphere, and is filled with strong corrosive fumes formed of concentrated sulfuric acid.

Although Venus has many physical and geological properties similar to Earth's, the high temperatures in its environment are unbearable, and even the surface of Venus will melt with lead.

This new type of rover is named “Zephyr” and its design concept is to minimize the required energy, and the electronic equipment it carries can withstand high temperatures up to 450 degrees Celsius and work normally. The designer of this type of rover was Geoffrey Landis of NASA's Green Research Center. The project was presented as part of NASA's "Advanced Innovation Concept" (NIAC) program.

Venus is often referred to as "the twin sister of the earth". The reason why this is said is mainly because its material composition, size, and gravity intensity are relatively close to Earth's. Both of these are mainly silicates and Metal is the planet formed from the main raw material. In fact, Venus is definitely one of the planets with the harshest and most terrible environment in the solar system. Venus is covered by a super thick atmosphere and is filled with strong corrosive fumes formed of concentrated sulfuric acid. Among all four terrestrial planets in the solar system, Venus has the most dense atmosphere, and almost 100% of the second-phase components are carbon dioxide. The atmospheric pressure near the surface is 92 times the atmospheric pressure on the surface of the earth.

Dr. Landis said at the NIAC 2013 spring meeting in Chicago, United States, in March this year: “Compared to Mars, the inspection of Venus is not enough. It is indeed a difficult task to carry out the exploration of Venus. ”

Dr. Landis suggested that if we want to reach the goal of visiting Venus, we should try our best to consider if we can make the best use of local resources. He said: "Another key factor is that we must use components that are resistant to high temperatures so that the detector can survive such a high temperature environment on Venus."

The environment on Venus can almost be compared to the inside of a started engine, and engineers at the Green Research Center had previously had equipment that could be tested in the running engine. According to the research team, their electronic components can continue to work even at a high temperature of 450 degrees Celsius.

The wind speed near Venus on the surface is generally less than 2 miles per hour (about 3.2 kilometers), but it can provide considerable driving force. Therefore, Dr. Landis proposed: "If you can design a rover driven by sail will be very suitable for the surface conditions of Venus. The entire sail system has only two active joints, used to control the sail and adjust the direction of travel, so that this The rover will no longer need any power devices." This means that the rover will automatically drive without the need for any power system.

The envisaged three-wheeled rover is about 7 meters high. Of course it will not be the fastest rover. Most of the time it will stop at the site to carry out the investigation work, and from time to time it will move a distance and go to a new location to continue work. Landis said: "The surface of Venus is very flat in most places, there is almost a flat parking lot covered with rocks." According to the design, this rover can freely make forward or backward movements. In this way, once trapped, the rover can get out of trouble through reversing.

Landis and colleagues carefully designed the project funded by the NIAC project. They envisaged covering up to 12 square meters of solar panels on this rover and trying to get it to run on Venus surface for one month. Left and right, about 15 minutes of "sailing trip" every day. He said: "The design of this Venus rover does not go beyond the scope of physics. If we can use innovative concepts in the detector design, we will be able to make it survive in this furnace, and only need very little Energy supply can work smoothly." (Breakfast)

Applications :

Food & Drink
Salt (Sodium Chloride) is a well known flavour, preservative and a texturiser. 

PDV, Granular and Tablet salt all play their part in the food manufacturing processes either as a food ingredient or as a water softening salt used on the plant. 
Chemicals & Manufacturing Used in many manufacturing processes and as a raw material in the chemical industry

Textiles & Dyes

Salt(Sodium Chloride) is added when dying cotton and viscose textiles to assist in fixing the dye. In dye manufacture, salt can be used to bring the dye out of solution at the end of the manufacturing process, a technique known as 'salting out'. Salt can also be used in the 'standardisation' of dye mixes, to ensure uniformity of dye strengths between different batches. Finally, salt is sometimes used as a grinding agent to reduce the dye compounds to a powder.
