NASA admits it is difficult to find life beyond Earth

Scientists have long been eager to seek life in the universe, however, the US Aerospace Agency (NASA) said, "it is difficult to find life beyond Earth."

It is difficult to find life beyond Earth

According to the Guardian, NASA scientists met yesterday to discuss the quest to find extraterrestrial life about to be deployed, such as using satellites, spacecraft, exploration ships and Mars, Jupiter, a cottage. planet.

" The scientific community is united, hoping to find life in the universe, " said Dr. John Grunsfeld, NASA scientist. However, he admitted, "it is difficult to find life beyond Earth."

"We can't even define exactly what signs of life are."

Grunsfeld said many tasks will be deployed on Mars in the coming years. Accordingly, Curiosity exploration robots will continue to explore Mars. In April, it found water on the surface of the red planet. In addition, in 2016-2018, the European Space Agency (ESA) will deploy the ExoMars Mars exploration program, in search of signs of life here.

" Mars's surface is flooded with ultraviolet rays and radiation," Grunsfeld said. Therefore, the amphibious ships will " drill deeper into the ground than any previous lander." It has the ability to drill down into the Martian crust for tens of meters, where the lethal radiation on the surface of Mars cannot reach.

Many areas on Mars exist frozen water, located on top of the two polar polar glaciers, or below the surface. There may be life there, however, " to get to those places, is a great challenge, " Grunsfeld said.
