In the dust grains collected by the Japanese craft Hayabusa-2 from Ryugu asteroids and sent to Earth, found – among other things – one water drop, as announced by Japanese scientists. A discovery that strengthens the theory that life might have developed in the space and then transferred to our planet from outside, when asteroids or comets with water “bombarded” the Earth.
“This drop of water is of great importance. Many researchers believe that the water was transported (from space). In fact we discovered water on Ryugu, a near-Earth asteroid, for the first time“said Tohoku University lead researcher Tomoki Nakamura to AFP, who made the relevant publication in the journal “Science”.
Hayabusa-2 was launched in 2014 and returned to Earth two years ago with a 5.4 gram sample from the asteroid located 300 million kilometers from Earth. The analyzes so far, as reported by APE-MPE, had already found organic materials and some amino acids, which are the cornerstones of life.
China is planning a double mission to Jupiter and Uranus for 2030
THE China designs one ambitious space mission, planning to launch, around 2030, with one rocket at the same time two ships that will target two different planets, Jupiter and Uranus.
The mission, named Tianwen 4, to be launched on China’s largest Long March 5 rocket, will include a pair of craft: a larger one for giant Jupiter and a smaller one for distant Uranus. Relevant information was given by the China National Space Administration (CNSA) at an international astronautical conference in Paris.
The main spacecraft will study the Jupiter system and eventually orbit the satellite Callisto. The smaller craft will attempt a close pass by Uranus. The scientific goals of the mission are still under discussion, according to Space.com.
China launched its first interplanetary mission in 2020, sending the Tianwen 1 spacecraft and Zhurong rover to Mars. This particular mission was awarded a few days ago by the International Astronautical Federation during the astronautical conference in Paris.
The 240-kilogram, solar-powered Zhurong rover is currently in “hibernation” until the Martian winter passes in the planet’s northern hemisphere. It is expected to resume its activities in December or January, when it will be able to receive more solar radiation.
China is planning the complex Tianwen 3 mission, due to launch in 2028, with the goal of bringing the rover’s collected samples back to Earth. It will be preceded in 2025 by the Tianwen 2 mission to collect a sample from asteroids and return it to Earth.
