How NASA painted the Perseverance rover to withstand Mars' extreme temperatures

Following is a records of the video clip.

Narrator: Getting among NASA’s automobiles right into area takes design, the rules of aerodynamics, great deals of scientific research, as well as an unique paint work. This is NASA’s Mars 2020 rover.

It’s arranged to arrive on the red earth on February 18, 2021. NASA paints every one of its Mars vagabonds, as well as Mars 2020 is no exemption.

But repainting an automobile for an unusual globe is a lot various from repainting a cars and truck. For beginners, the procedure is all done by hand. The Mars 2020 rover began as a heap of light weight aluminum panels that took 4 months as well as over 5,000 hrs to construct. It’ll take one more 3 to 4 months to turn the framework, additionally called the framework, right into a finished rover.

That’s where the repaint work can be found in. The rover beings as a glossy light weight aluminum that is after that painted white to show sunshine as well as assistance the rover from overheating. Unlike the paint we placed on cars and trucks, this paint is much more long lasting. It’s made to withstand the extreme temperatures of Mars, which can vary from 70 levels Fahrenheit, 20 levels Celsius, near the equator, to minus 100 levels Fahrenheit, minus 73 levelsCelsius In truth, you can still see areas of white paint on NASA’s Curiosity rover, which has actually gotten on Mars given that 2012.

Many locations on the framework demand to be painted, while various other components will not have any type of paint in all. These locations normally have digital boxes, electrical wiring, or delicate clinical tools. To safeguard them throughout the procedure, these locations are meticulously concealed with tape. Emphasis on meticulously. Instead of simply duping an item of tape, it is exactly gauged as well as reduced by a computer system.

Then the rover is fined sand to scuff the glossy, smooth light weight aluminum which assists the repaint stick far better. As for the paint, it is especially created to withstand all the troubles of obtainingto Mars Like the unstable trip throughout launch as well as touchdown, in addition to black blizzard onMars For the paint to job properly, it has to be the best density as well as equally used. Once the paint is used, NASA has to ensure the rover’s surface area can not take in anything like water or various other chemicals.

So they cook it.

This occurs in huge, thermal vacuum cleaner chambers. The framework is prepared in the vacuum cleaner for 3 days at 230 levels Fahrenheit, 110 levelsCelsius The rover is after that covered with 2 bags to safeguard it as well as transferred to an air lock area. This area preparations the rover to go from the filthy outdoors to the tidy within the setting up center. The external bag is eliminated as well as the tidy, indoor bag is left on for the rover to go into. Once the internal bag is eliminated, last setting up of the rover can start.

All the parts that regulate the rover, in addition to all its tools, will certainly go within the framework, creating the structure for the wholerover Who understood paint could additionally count as brain surgery? See you in 2021, Mars.
