Hayabusa-2 was launched in 2014 to reach Ryugu, which is around 300 million kilometers away.

The roughly refrigerator-sized Hayabusa-2 spacecraft reportedly landed on the diamond-shaped asteroid Ryugu, which was given the name Ryugu after the Japanese term for “dragon palace,” according to Phys.org.

The probe impacted an “impactor” into the surface, collecting 5.4 grams (0.2 ounces) of rocks and dust. The discovery of water in an asteroid sample for the first time sheds light on the possible origins of the oceans on Earth. The Hayabusa2 spacecraft from Japan made the discovery.

The Japan Aerospace Exploration Agency, Tohoku University, and other research teams published their findings in the journal Science on Thursday. Scientists studied the Ryugu asteroid samples that the Hayabusa2 sent.

The minuscule amount of water was discovered in a dip in an iron sulfide crystal that was several microns wide. It is believed to have existed roughly 4.6 billion years ago, not long after the solar system first formed. On Ryugu, though, the water appears to be liquid rather than frozen. Salts, organic debris, and carbon dioxide were all present in the carbonated water.

Despite the fact that water had already been discovered in a meteorite, it was still feasible for it to have originated on Earth. A prior study of a Ryugu sample had suggested the presence of water, but this was not confirmed until water and minerals began to interact chemically.
Tomoki Nakamura, a professor of earth science at Tohoku University, made the observation that an asteroid that collides with the Earth and contains water also carries organic material. The origins of living things and the origins of the oceans are directly tied to this information.

The Ryugu samples are still being examined in Japan by eight research teams. It is predicted that more details about the makeup of organic matter, including the 23 amino acids that have already been discovered, will be found.

This technology is determined to reduce water scarcity in the future. Water scarcity will be a threat to human survival in the coming years with the increase in global warming situation. The sea level is rising rapidly and salt water will submerge all the remaining lakes and rivers. According to the estimated data, about 230 million people from the African continent will face water shortages by 2025.

The technology promises to produce fresh water by the process of removing salt from the seawater. A desalination plant is aiming to convert seawater into drinkable water. Researchers have effortlessly filtered salt water with the help of fluorine-based nanostructures. The fluorine nanochannels have performed more effectively than conventional means of distillation.

Converting seawater to drinkable water is an already established practice but it’s not energy efficient.  However, an Associate Professor of the University of Tokyo named Yoshimitsu Itoh at the Department of Chemistry and Biotechnology has been investigating on fluorine pipelines or nanochannels for a decade.  Fluorine is a lightweight ingredient that also consists of water-repelling properties. Due to its hydrophobic quality, it can be used as a component for Teflon. Teflon is used to enhance the flow of water. The associate professor and his colleagues were intrigued by this property.

So, they developed filtration membranes by chemically producing nanoscopic fluorine rings. Those fluorine rings were assembled and implanted on the lipid layer. The nanorings were sized from 1 to 2 nanometers. Fluorine is a negative component that repels another negative ion such as chlorine found in salt and this is the technique they are using to separate salt from water.

Researchers said that the materials that will be used are energy-intensive but has more longevity. The member has a low operational cost. So, the total production will be highly energy-sufficient.
