According to NASA’s site about a trip to Mars, they estimate that “ your trip to Mars would take about 21 months: 9 months to get there, 3 months there, and 9 months to get back.” In these 21 months, countless things could go wrong; the takeoff could go wrong, the astronauts could run out of food, Mars’s atmosphere could be toxic to humans, they may not be able to leave Mars’s atmosphere, and when they enter Mars’s or Earth’s atmosphere things could go not as planned. The astronauts have a high risk of losing their lives, and their families will be the ones that are suffering, then NASA will turn around and just make another trip to Mars as if nothing ever happened. We need to be careful when making the decision to send someone to Mars because they are taking all the risk, while we are just enjoying watching them; also in Fraser Cain’s article ‘Should we go back to Mars or back to the moon’ he says “This means that a journey to Mars with even a short visit to the surface will take the better part of 2 years. Astronauts will be beyond any kind of rescue and completely reliant on their spacecraft and supplies for that entire …show more content…
In the beginning of Tyson’s article he argues that “Mars has a 24-hour day. It has polar ice caps. Its axis is tilted compared with its orbit, just as Earth is tilted on its axis. That means Mars goes through seasons, just like Earth.” Tyson Argues all of this, but there is still a problem, Mars still does not have water or vegetation, or oxygen, and it would likely cost trillions of dollars to get Mars to be just like Earth, and if something went wrong on the way to Mars with the resources, it would be a wasted trip. Tyson continues to argue his point later in this article when he says “We learned in the 1960s that Mars 's surface has features that, as far as we can tell, can only have been made in the presence of water: standing water, running water, deluging water. There are features that look like they 're floodplains. There are riverbeds that are straight and riverbeds that meander.” Tyson Argues that life on Mars is within our reach, because at one point, it contained water. The problem is that it does not contain water anymore, and we would have to figure out how we are going to transport water 33.9 millions miles. Some believe that there are underground water reservoirs, but if there were underground reservoirs of water, there would also most likely be clouds, and we would likely be able to see some above ground water; the water also may not be drinkable.
