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 o

The reading passage has discussed three challenges to sending humans to Mars which have been refuted by the lecturer by presenting evidence against the conclusion of this passage. The passage discussed that sending humans to Mars is unlike to mission to the Moon as the mission to Mars would require solving various problems that were not faced by the people who went to the moon.

Firstly, the reading passage discussed that the mission to Mars can take at least two years to finish a round trip and it will be difficult to transport necessary food, water, and oxygen. Though the trip to the moon can be finished within a few days, a Mars mission is not possible without the necessary materials. However, the lecture is concerned with discussing the use of hydroponic which can help humans to grow necessary foods during their mission to marsh and recycle necessary water, and oxygen without taking food, water, and oxygen load from the earth.
Secondly, the passage outlined that astronauts on the Mars mission would have to suffer from Zero gravity problems as they would have to stay in space for a very long time. The human body can suffer from lower bone density and decreased muscle mass due to the negative effects of a zero-gravity environment. However, the lecturer provided evidence of space stations where astronauts are spending months after months without suffering many problems.

Finally, the reading passage discussed that astronauts can face the problem of space radiation due to their exposure to dangerous levels of radiation as there will be no Earth's magnetic field to protect spaceships that are traveling in interplanetary space. Moreover, creating shields to protect the spaceship is impossible due to the added heavy weight of the ship. However, the lecture has refuted this challenge by outlining the use of thin layers of material which can reduce the problem of space radiation.

To recapitulate, it can be said that the claim of passage is not substantiated if humans can use hydroponic to produce food in space, spaceships can take a rest in a zero-gravity station, and low-weight material can reduce space radiation.
