Which Chinese space probe touched down on the far side of the moon? |
| Answer» Chang'e-4 lunar probe, a Chinese space probe, touched down on the far side of the moon. The probe, which has a lander and a rover, that was launched in December made the soft landing and transmitted the first-ever close-range image of the far side of the moon. It touched down at a targeted area near the moon's south pole in the Von Karman Crater. The purpose of the Chang'e-4 includes astronomical observation, surveying the moon's terrain, landform, and mineral makeup, and measuring the neutron radiation and neutral atoms to study the environment of its far side. The moon is tidally locked to Earth, rotating at the same rate as it orbits our planet, so most of the far side or dark side is never visible to us. Previous spacecraft have seen the far side, but none has landed on it. China's space agency hailed the event as a historic first and a major achievement for the country's space programme. | |

The researchers of this country developed a system that can produce electricity and hydrogen fuel from carbon dioxide. |
| Answer» Scientists from Ulsan National Institute of Science and Technology (UNIST) in South Korea have developed a system that can produce electricity and hydrogen fuel from carbon dioxide. The Hybrid Na-CO2 system can continuously produce electrical energy and hydrogen through efficient carbon dioxide (CO2) conversion with stable operation for over 1,000 hours. The key to this technology is the easy conversion of chemically stable CO2 molecules to other materials. Much of human CO2 emissions are absorbed by the ocean and turned into acidity. The researchers focused on this phenomenon and came up with the idea of melting CO2 into water to induce an electrochemical reaction.If acidity increases, the number of protons increases, which in turn increases the power to attract electrons. If a battery system is created based on this phenomenon, electricity can be produced by removing CO2. In particular, this system has shown stability to the point of operating for more than 1,000 hours without damage to electrodes. The system can be applied to remove CO2 by inducing voluntary chemical reactions. | |

| Answer» The 340m wide asteroid named 99942 Apophis will fly past Earth like a 'moving star- like point of light' on April 13, 2029. It will fly above the earth's surface at 30,500 km and first become visible with a naked eye in the night sky over the Southern Hemisphere from the east coast to the west coast of Australia.In 2004, astronomers at the Kitt Peak National Observatory based in Arizona discovered Apophis and claims about the chance of 2.7% that asteroid may impact Earth in 2029. However, further observation ruled out that chance but Apophis still has a small chance of impacting Earth which is less than 1 in 100,00- many decades from now. | |
