Why Has Mankind Not Yet Reached Mars? Let Us See Some Reasons

1 Mins read

There’s a lot of talk about landing on Mars in the near future, but why haven’t you done this before? There are many reasons: until a few years ago, governments and private agencies were not as interested in space as they are today and NASA says there are a number of obstacles that we still have to overcome to make it.

What are these obstacles? They can be summarized in: arrival, landing, living and returning; at least according to Michelle Rucker, head of NASA Human Mars Architecture Team at the Johnson Space Center of NASA and Jeffrey Sheehy, chief engineer of N

The first obstacle is the distance, since Mars is an average of 254 million kilometers away and at its nearest point is only 55 million kilometers away; this time window of proximity occurs every 26 months and, with the technology currently in our possession, a hard journey The propulsion system also plays an important variable; to reach Mars faster it might be useful to use nuclear thermal or nuclear propulsion.

Sheehy and Rucker estimate that the spaceship should be at least the size of a football field in length (like the one that wants to build China). Not only the journey, but also the landing is important: NASA is working on the development of an inflatable decelerator, a kind of parachute that would protect and slow down the landing medium as it penetrates the atmosphere.

Another important difficulty is to live on the Red Planet. Microgravity has impacting effects on the human body and, together with Mars radiation, it could be very dangerous to live on the planet. Moreover, the first astronauts of the celestial body will have to be locked up in small spaces for a long time without many external contacts. Certainly a psychological test.

There are hundreds more problems with a mission on Mars, but humanity is going to solve them all with the aim of becoming a multi-planetary species. Is that really gonna happen? Let’s see. Meanwhile, we await the human return to the Moon in – theoretically – 2024.
