Honored scientist of NASA, one of the developers of the program Voyager, Professor of physics Edward stone, convinced of the need to thoroughly explore Saturn’s moon – Enceladus. It was there, in his opinion, is most likely the existence of extraterrestrial life in the Solar system.
It all started with Voyager
The program “Voyager” became one of the most successful projects in the history of interplanetary studies – two spacecraft gave scientists high-quality images of Jupiter and Saturn and crossed the border of the Solar system. They were launched in 1977 and still perform their research tasks. Recently, “Voyager 2” astrophysicists reported the most complete data on the structure of the heliosphere.
American physicist Edward stone worked in the program “Voyager” since 1972, and since 1991 has headed the jet propulsion Laboratory of NASA. He was a witness and participant of many scientific discoveries in the field of space, but considers that one place in the Solar system should be examined more closely. He calls back to Enceladus, one of Saturn’s moons, whose frozen oceans are considered the most promising place to find extraterrestrial life within the system, writes the Guardian.
We really need to go back and search this month. We know that water ice evaporates there – gushes – at the South pole. All the time there is snow. This means that under the icy surface there is liquid water. Here on Earth, where there is water, there are microorganisms,
– stone said.
The Study Of Enceladus
Before “the Voyager” took pictures of Saturn and flying past in the 1980s, Enceladus was just a speck on the backdrop of the rings of this planet.
Image showed that its surface is covered by pure ice, and geological activity indicates that in the depths there is a source of heat, which supports the ocean in a liquid state.
In 2017 the device “Cassini” flew to Saturn and passed through a fountain that shoots up through cracks in the surface of the satellite. He confirmed the presence of liquid water and organic components. However, the study of Enceladus has not been completed, and the question of whether there is life remains open.
According to stone, it would be better to fly through the geysers and to bring to Earth samples to see if there’s germs. The probability to find there the germs high. So researchers will be able to see them and understand the earth they are related or differ.
