There are many reasons why going to Mars is important. First, Mars is the most likely planet for us to colonize. No matter how expensive, we need to work on getting there as soon as possible. Furthermore, the technology that we would need to develop to send humans to Mars would directly benefit our economy here on Earth. Just look at the money-making products that have already resulted from NASA’s space efforts: invisible braces, water filters, cordless vacuums, to name just a few. Although we have already sent robots to Mars, robots can’t take the place of humans when it comes to studying the planet. A robot may break down. Also, it takes robots much longer to cover the same amount of ground than it would a human. Think how much faster we could learn about the planet if we sent humans to work alongside the robots! Finally, claims that there will be significant health problems for people who travel to Mars are wrong. Studies have shown that radiation levels on Mars are not lethal to humans. Sure, we would have to live in a dome at first, but over time, we could use science to change the atmosphere and make it possible to go outside, just like on Earth! The choice is clear. We need to go to Mars now! Article 2 Mars—A Waste of Time and Money By Juniper Springs While it might be fun to imagine traveling to Mars one day, now is not the time to go. For one thing, it is too dangerous. The atmosphere of the planet is more carbon dioxide than oxygen, and it’s very cold. While there are claims that the radiation levels on the planet are not lethal to humans, that does not mean they aren’t dangerous. We don’t yet know what the long-term health effects will be. As of now, we do not have a sol
