CALIFORNIA – National Aeronautics and Space Agency (
NASA ) released a
video explaining the factors that led the agency to believe that planets
Mars in ancient times the same as the Earth.
As reported by The Sun Sunday (16/10/2021), the scientist, dr. Becky McCauley Rench said they thought Mars was more ‘humid and warm’ when it first appeared. READ ALSO – Why Elon Musk Wants to Build a Car Factory on Mars
“When the solar system existed about four billion years ago, Mars and Earth were made of the same material, thus making the two planets look the same.”
“However, today if we look at Mars, it looks like a dry planet compared to Earth which has a blue color. We believe Mars had a shallow northern ocean before, but it has disappeared, thus setting the two planets apart,” Rench said in the video.
The relatable similarities between the two planets are important to scientists because they can help them find clues to ancient life on Mars.
“Geological activity on Mars during that time period decreased, during which it lost water and eventually became a drier planet. This is different from Earth where the planet continues to go through a process of ‘progress’ with plate tectonics and the development of life,” he explained.
In addition, scientists also believe that the element of water still exists on the surface Mars at this time but in the form of ice.
They also believe that the planet’s subsurface has plenty of water, but more research is needed to confirm that.
