Scientists are considering the possibility of sending humans to Mars in the coming decades. Although there have been successful manned missions to the Moon in the 1960s and 1970s, Mars is 150 times further away from Earth than the Moon is. Thus the project of sending humans to Mars would require solving an array of problems the Moon missions did not have to face.
One problem is that a round-trip to Mars and back is likely to take at least two years. The trip to the Moon lasted only a few days, and it was easy to bring enough supplies of food, water, and oxygen; but the cargo capacity of space vehicles is too limited to put on board the food, water, and oxygen required by a crew for a period of two years. Without those essentials, though, a Mars mission is impossible.
A second problem is that astronauts on the Mars mission would be in the zero-gravity environment of space for many months at a time. Spending a long time in the zero-gravity environment has negative effects on the human body, such as decreased muscle mass and lower bone density. Over the course of a two-year mission, the effects would be so severe, they would make it impossible for humans to make the trip without experiencing grave medical problems.
Finally, astronauts on a mission to Mars would be exposed to dangerous levels of space radiation, much of which comes in the form of charged particles emitted by the Sun. Earth's magnetic field, which normally protects us from dangerous solar radiation, would not be able to protect a spaceship traveling in interplanetary space. Constructing a shield that would protect the whole spaceship from space radiation is at present impossible because it would add too much weight to the ship.
In this set of materials, the reading and the lecture both discuss whether or not the trip to Mrs will be possible for many months as the trip will facing many problems in comparison to trip to moon. While the readind states that sending humans to Mars require solving these difficulties that moon's trip never face it. The lecture says that although this trip will be challenging but sciences have been solve them and provide explination for solving these problems.
First of all, the readind claims that mars trip back and forth takes 2 years which is lopng period and requirs many equipments to be taken with but the cargo capacity cannot takes all these supplies like food,water, and oxygen and makes this mission imposible. On the other hand, the lectureargues that astronats can use Hydroponic technique by planting the plants roots in water rather than soil and they could cultivate food. Furthermore, thew professor adds that this process will occupy little space and can help recycling water to be transform to vapour water for drinking and exchange co2 to fresh air. All mentioneed benefits for this technique will make spending years in trip tp Mars possible.
In addition, the reading makes the argument that an astrounat will be subjected to zero garvity and will affect their healths by lossing muscle mass and bone density. However, the lecture counters this point by saying that there are many space station which astrounats sprnds months in it and they overcome their health and medical problems by using special techniques like reguler exercise and take vitamines like calcium.
Lastly, the reading asserts that such a trip will causea serious problem tov the humans as they will facing a harmful radiatio from comets. The writer mentions that our earth protect us fro msuch radiation because its magnetic field. Coversally, the lecture refuts this claim by pointing out thatastrounats will face some radiation and not all of them are harmfuland danger. Moreover, the professor says that to avoid these radiations there are monitor can be used and shulter that the astrounats can hide during the emmision of danger radiations and theses shulters are not add any weight to the vhicles whihc makes this trip possible and easily arranged.
