Mars Rover Explanation Writing

For the past 2 weeks we had to do a explanation writing. We had to make a plan about what we are going to write about. After we did that we got onto making it. We had to do it about Mars and its rover. Explanation writing is a piece of writing that explains something to your in a paragraph and doesn't tell you what its about it says in the writing. Here is my work.

Did you know Mars has a Rover? A rover is a robot prototype made by NASA and SpaceX. A rover takes 8 years to build. A rover goes to planets and takes samples of the land and pictures. It takes about a year for the rover to get there depending on what planet it will go to. Rovers can have new technology that won't be out in a year. Some rovers have autopilot and high tech cameras. You need more than 100 people to make one rover. One rover cost 25$ Million dollars or more to make one.

A lot of things could go wrong in the mission. They could get their coucalcion wrong on the fuel and not have enough or there is a hole in the fuel tank and all of the fuel falls out. They could go to the wrong place and get their coordinates wrong and head into a black hole. It could go to fast and explode but if it has an escape pod the rover could go in that and make its way to the spacecraft in space. The escape pod could land in the city and make you feel more sick and sore from the hard landing.
