NASA sent the Apollo 11 spacecraft into space in 1969, the first human landing on the moon, an event that was a very big event for the whole world, but it was not NASA's most ambitious act.
NASA has set a goal since then, hoping to allow humans to land on Mars in the future.
Although Mars is far from having the conditions for human survival on the moon, NASA sent Opportunity to test this.
The rover flew to Mars and operated for nearly 15 years, returning countless materials to researchers on Earth, and several satellites have also found some strange phenomena against these photos.
Previously, it was thought that the more suitable conditions for life on Mars have been taken away by all life on Earth.
The rover discovers life on Mars.
Scientists have long been yearning for this field, wanting to know if the Earth species are lonely and if there are other planets that have given birth to life.
The reason why people choose Mars is also because Mars is closest to us and closest to us, so scientists are also most interested in the laws and life conditions of this planet.
From 2004 to 2019, the rover has been walking on Mars, whether it is on Mars or after returning, it has brought us countless surprises, which is also the biggest source of power for this exploration rover to last for so long, and it is also the biggest reason why it can get financial support.
How much data has the rover collected?
Among the information it sent, there are many strange phenomena that are considered to be Mars, whether there seems to be a huge spacecraft wreckage, and many seem to be on fire, so some people once believed that there was intelligent life on Mars.
But there are also a large number of people who believe that this is because the growth environment on Mars is different from that on Earth, so this phenomenon is formed.
Because of this on Mars, it is believed that life on Mars could be underwater.
So it was in this situation that people captured the photos that proved the existence of water on Mars in the materials sent back by Opportunity.
However, satellites have also found more bizarre objects in the light of these photos.
What kind of creatures are the Martian creatures that Opportunity photographed?
In 2004, NASA launched Opportunity to Mars in an attempt to test hypotheses about Mars and to find evidence of signs of life on Mars.
Although it has been confirmed that there is water on Mars, there is still no evidence that life ever existed on Mars.
However, Opportunity observed a strange phenomenon, this time taken under the underground ice, and a lizard-like creature can be seen in the photo.
This lizard-like creature is very small, and as you can see in the photo, it is about 10 centimeters long and has something like a tail under its belly.
At first glance, this thing looks very much like a lizard, but one wonders: how did this animal survive to this point?
Although the temperature on Mars is moderate, how can animals that cannot live underwater survive until now?
Moreover, in the ice of the seabed, on the cold Mars, it is impossible for animals to survive to this day, which makes scientists doubt this creature.
On our planet, there are also many opportunities for living beings to survive without water, such as animals in the desert.
So is there a desert-like environment on Mars that can support the survival of life?
However, after careful study of this photo, scientists eventually discovered that this creature is only a form of mineral.
We humans, monkeys, and lizards are all creatures that feed on other animals, and if we want to be able to grow and reproduce, we must have an environment suitable for our own survival.
So the presence of lizards also proves that there were once creatures in this environment that could provide food for lizards.
At the same time, the appearance of lizards has also given scientists ideas about life on Mars, just like the twin-tailed snake discovered a few years ago, which is believed to be a living fossil of ancient life on Earth, and is also believed to be able to prove that life on Mars once intersected with life on Earth.
Although there is no accurate evidence to prove these things, there is more speculation about life on Mars under our inference.
Whether life exists or not.
Over the next five years, scientists have been working on this hypothesis.
They found a lot of evidence on Mars that life once existed.
For example, proteins found in Martian soil, which are biologically formed.
But there are also many scientists who are skeptical of this, arguing that these proteins are not necessarily biologically formed, and therefore cannot prove that life existed on Mars.
But if you think about it, why do these proteins end up in Martian soil?
Previously, they weren't necessarily in the form of living things, but they were certainly biodegradable, so if this protein wasn't biologically formed, then what else could explain that?
Besides, apart from the existence of living things, how are these proteins formed?
Some scientists believe that these proteins were formed by the dust of the universe, but among all the dust of the universe, none of them have ever formed proteins.
So their conjecture was ultimately rejected.
Life is very strong, and once there is a suitable environment, it can reproduce, but human beings can't find a suitable environment, so they have conjectures about this kind of thing.
Did life on Earth originate from Mars?
epilogue
If this is the case, then life on Earth will become very ordinary, not necessarily the newest life in the universe.
But in addition to the solar system, there is such a large universe, and we don't necessarily know how many planets and creatures there are in the universe.
This is the idea in Interstellar and the reason why humanity yearns for the future.
