This week we are learning to test our tires to maximize the competition capabilities of our planetary explorers. The better the traction the more force we can convey, and the more energy is transferred. You know that different environments (dirt, slick, concrete, etc.) need different tire designs, but what if the environment was another planet? Research the surfaces of one of the terrestrial planets, describe that surface here and then decided on the best tire type for a planetary explorer. Be sure to explain why you decided on this type of tire!

If we sent a rover to mars (again) we would need pretty heavy and thick tires. I think the tire should be like smaller monster truck tires. Mar's surface is rocky and dry. So our tires should have large ridges on the bottom to really grip onto the soil/ dirt like stuff.

This is a great start, but .... what kind of tires do the current rovers have? Why did they choose to make them the way they did? Is all (or any) of Mars dusty dirt? What design might you use for other areas and why? Do some research.

The surface of the planet Venus is described as having dense clouds, hot to 400 degrees, winds to 350 kph, water boils away, active volcanoes, covered by lava, is very dry, and has craters. This planet resembles the Earth. The best tire for this hot planet would be one that does not melt. And due to the winds, a tire that has a lot of grip to the ground for friction. Tires that would be adaptable to hot water would be useful. The tire I would chose based on this information would be made of something that has not been invented yet because all the tires we currently use would burn or melt on this planet. There are no tires that can sustain this kind of heat on Venus.

Nice addition Chance, full credit! ...but you mentioned that this planet resembled Earth, doesn't sound like it from your description, tell me how. Also, we have put probes down on the surface of Venus, find out what those were made of and maybe we'll have the material for the wheels you described!

The planet Venus has a smooth surface and we cant use tires that are meant for rough terrain because Venus has a smooth surface you need tires that just drive smooth on the road. Dirt you can use the tires that meant for rough terrain because the tires that meant for the terrain they grip the ground and they go over rocks. I would pick tires that are meant for smooth surfaces and tires that are meant for rough terrain for you can go over rock, trees, and go up mountains .

The surface of Neptune has a thick slushy fluid of water, ammonia, and methane. Also, since it is a great distance from the sun the winds can get up to 1,500 miles per hour. The Great Dark Spots are linked to the winds and are appearing and fading over the last decade. So, the tires would have to be able to float but "stick" to the fluid enough so it would not be blown away by the winds and Great Dark Spots.

Good work! ...but could we really float on Neptune? Comments are closed.
