Goodyear and NASA have designed a great tyre to ensure safe, successful, space exploration. Astronauts know that they cannot afford to puncture a tyre when they are millions of miles away from the nearest garage. It is important that they adapt quickly to any surface to prevent unnecessary problems. NASA and Goodyear likely consider every detail during the design phase of the project. These tyres will likely be better and more expensive than regular ones. Quality is essential which suggests that NASA is willing to pay for great service and a superior product. The load bearing springs protect the tyre and allow it to function until it is replaced with a new one.
Studies suggest that Mars has iron oxide on its surface which gives the planet its reddish appearance. This colour results from dust in the atmosphere. Mars is further away from the sun which suggests that its surface is harsher than Earth’s. The planet is also less dense than Earth’s. Experts claim that Mars has the highest mountain in our solar system. The planet has geological and geographical features which are similar to ours. These features include; mountains, dormant volcanoes, canyons and other harsh terrain. Volcanic activity likely occurred during the planet’s history. Lack of water suggests that life was unlikely to survive on the “Red Planet’. The planet’s crust is any where from 50km to 125km thick. It is thicker than Earth’s crust which is about 40km.
Experts have long debated whether life exists on Mars. The planet often captures the imagination as people become fascinated by it and space. Novels such as ‘War of the Worlds’ helps to excite interest as they adapt scientific facts to suit their readers. Some scientists suggest that life cannot exist on Mars as the extreme temperatures make it difficult for anything to survive. It can be anywhere from -140 degrees C to 70.7 degrees C throughout the year.
