Weather conditions on Mars?
Temperatures range from −140 ° C in polar winters to 20 ° C in summer. The strong thermal excursion is also due to the fact that Mars has a thin atmosphere (and therefore a low atmospheric pressure) and a low capacity to retain the heat of the ground.
Unlike Earth, Mars does not have a magnetic field and thick atmosphere capable of protecting the surface from radiation. As for communications, if those on Mars wanted to send a message to people on Earth, they would have to take into account that it would take 15 minutes to get there.
The terraforming of Mars is a hypothetical process by which the red planet's climate, surface and known characteristics would be modified with the aim of making the planet habitable by humans and other terrestrial life forms, thus providing the possibility of a safe and ...
The soil of Mars is covered with a multitude of rocks and a layer of sand a few centimeters deep. Another important feature of Mars are its polar caps: they are stratified deposits of carbon dioxide and sand that cover the planet's poles.
On 7 June 2018, NASA launches an important statement: on Mars there are organic molecules and methane in the atmosphere varies cyclically, requisites for having hosted life in the past and perhaps to welcome it still today.
The average distance from Earth to Mars (2,20 108 km = 220 000 000 km) is equal to: 2,32 10-5 AL (light years);
On Earth the force of gravity is equal to about 9.81 m / s2 (1 g), while on Mars, being its mass less than that of the Earth, the force of gravity is equal to (0,377 g). Our weight on Mars is therefore 2,65 times less than on Earth.
The average surface temperature of the planet is 63 ° C below zero, with lows of 140 ° C below zero and maximums of 20 ° C above zero.
According to the company's plans, the settlement should start by 2032.
Seen from Earth, Mars appears as a reddish planet, because it is rich in oxidized iron minerals.
Values in billions of dollars. The mission to Mars with the Perseverance rover and the Ingenuity aircraft cost 2,9 billion dollars actualized, less than the previous Curiosity mission which required 3,2 billion dollars and the Viking 1 and 2 probes which overall absorbed 7,1 billion dollars. Dollars.
The first idea of sending a human crew to Mars dates back to 1948 by a German missile engineer, Wernher von Braun, with a mission with 10 spaceships and a crew of 70 people.
If only they tried to put their nose outside their Martian home, without any protection, their blood would literally start to boil due to the strong difference in pressure between the inside of their body and that of the external environment.
According to NASA's Goddard Space Flight Center website, with current means the travel time required to bring humans to Mars is expected to be around nine months, and unmanned spacecraft sent to date have taken 128 to 333 days to reach the red planet.
Some of the major space agencies predict a return to the moon with human missions around 2030, including NASA in 2024 with the Artemis program and the Chinese space agency in collaboration with ESA and Roscosmos.
The first photo of NASA. AGI - After a seven-month journey, NASA's "Perseverance" rover successfully landed on Mars and sent its first image of the red planet's surface, opening a new era in the history of space exploration.
On the Moon (in the photo) the temperature of an illuminated area is around +150 ° C, that of a shaded area around -150 ° C. There is no gradualness: a person lying on his back on the moon would be heated to 150 ° C on the exposed part and cooled to -150 ° C on the back.
Mars' orbit is remarkably elliptical; the inclination of the orbital plane on the ecliptic is 1 ° 51 '. The average temperature is around -15 ° C; in the equatorial regions there are temperatures fluctuating during the day between +10 and + 20 ° C; during the night, however, the temperature drops to - 80 ° C.
This means that our weight is about 2,65 times lower than that of Earth on Mars and about 6 times lower on the Moon. Taking into consideration a person who weighs 75 kg, he would weigh about 28 kg on Mars and about 12 kg on the Moon. In short, rather low values compared to the terrestrial ones.
To calculate the weight force exerted by one body on another we use Newton's formula F = G m1M2 / R2, where G is the universal constant of gravity, m1 the mass of the (small) body M2 the mass of the large body and R is the distance of the small body from the center of the large body which ultimately corresponds to the radius of the ...
The weight in newtons is calculated with the formula P = m · g; on Earth g is worth about 9,8 while on the Moon it is about 1,6. Therefore the weight on the moon of a 70 kg man is equal to 113,4 newtons.
Due to the discreet eccentricity of its orbit, equal to 0,093, its distance from the Earth to the opposition can oscillate between about 100 and about 56 million kilometers; only Mercury has a higher eccentricity in the Solar System.
On a scale where the Earth was 1 cm in diameter, one light year would correspond to a distance of 7423,80 km. Light takes about 8,33 minutes (8 minutes and 20 seconds) to travel from the Sun to the Earth. One light hour corresponds to approximately 1,08 billion kilometers (approximately the distance between the Sun and Saturn).
We have found that, traveling at the maximum speed that a car can reach on the highway, it takes about 8,3 million years to travel a distance equal to 1 light year.
The result would be a cardiovascular collapse. The first causes of death would therefore be lack of oxygen and collapse. The nervous system, on the other hand, takes longer to get damaged, in this case due to the nitrogen dissolving in the blood.
