On March 17, 2023, China’s Ministry of Science and Technology released its annual list of the top 10 domestic scientific advances for the year 2022. This list aims to recognize and celebrate the achievements made by Chinese scientists in various fields of science and technology.
At the top of the list for 2022 is the Martian subsurface structure revealed by the Mars rover Zhurong’s radar instrument. This accomplishment marks a significant milestone in the exploration of Mars, as it offers new insights into the planet’s geological history and climate conditions. The study not only revealed detailed subsurface features of Mars but also provided observation evidence of the presence of water. This discovery is critical in advancing our understanding of Mars and its potential for supporting life.
The Mars rover Zhurong, which landed on Mars in May 2022, has been conducting various scientific investigations on the planet’s surface, including geological, environmental, and atmospheric studies. The rover’s radar instrument is one of the most crucial tools for exploring the Martian subsurface. It uses radar waves to penetrate the planet’s surface and provide images of the subsurface structure. The data collected by the radar instrument has enabled scientists to create a detailed map of the Martian subsurface, revealing important geological features such as underground rivers, valleys, and canyons.
The Martian subsurface structure revealed by the Mars rover Zhurong’s radar instrument is a significant breakthrough for the scientific community, providing new insights into the geological history and climate conditions of Mars. This accomplishment showcases China’s commitment to advancing space exploration and its contributions to the global scientific community. The scientific discoveries made by the Zhurong rover have the potential to advance our understanding of Mars and contribute to future exploration and colonization efforts.
In recent years, the discovery of active, repeating, fast radio bursts (FRBs) has been of great interest to astronomers and scientists worldwide. The Five-hundred-meter Aperture Spherical Radio Telescope (FAST) located in China detected these FRBs, ranking it as one of the most significant astronomical discoveries in recent times. This discovery has laid the foundation for further observation, which may unravel the mysteries surrounding the origin of these radio waves.
FAST is the world’s largest single-dish radio telescope and has been instrumental in the detection of these active, repeating FRBs. These FRBs are short-lived bursts of radio waves that emanate from deep space, and their origin has remained a mystery until recently. With the discovery of these FRBs, scientists and researchers are now able to study and understand the possible sources of these radio waves, such as neutron stars, black holes, and other mysterious celestial objects.
The discovery of these active, repeating FRBs by FAST has been significant because it opens the door to a new area of study in astronomy. These FRBs have been observed to be repeating, which means that they are not random and have a regular pattern. This regular pattern suggests that they could be coming from a specific object in space and not a random occurrence. Scientists are now able to use the data from these observations to develop theories and models that could help explain the origin of these radio waves.
The discovery of active, repeating FRBs by FAST is a significant breakthrough in the field of astronomy. It has provided the necessary foundation for further observation and study, which may help unravel the mysteries surrounding the origin of these radio waves. The data collected from these observations will help scientists and researchers to develop new theories and models, leading to a better understanding of the universe and the objects within it.
The innovation that clinched the third spot is a new principle and technology for generating hydrogen directly from seawater. This breakthrough addresses a persistent technical challenge that has long troubled the industry. Hydrogen is a versatile fuel with multiple applications, from powering fuel cells for vehicles to producing electricity in power plants. However, it is currently produced mostly from natural gas, a fossil fuel. This process emits carbon dioxide, a greenhouse gas that contributes to global warming. The alternative method of electrolyzing water requires large amounts of electricity, which is mostly generated from non-renewable sources.
In contrast, the new hydrogen generation technology directly extracts hydrogen from seawater by passing an electric current through a membrane. This membrane separates hydrogen and oxygen atoms, which are abundant in water molecules, and enables the hydrogen to be captured and used as fuel. The technology has the potential to revolutionize the way hydrogen is produced and used, as it could significantly reduce greenhouse gas emissions and reliance on fossil fuels. It also has the added benefit of utilizing seawater, which covers over 70% of the Earth’s surface and is a virtually inexhaustible resource.
Other scientific breakthroughs recognized in the ranking include research on COVID-19 variants and immune escape mechanisms. With the emergence of new strains of the virus, understanding their unique characteristics and potential for immune evasion is crucial for developing effective vaccines and treatments. The development of high-efficiency perovskite solar cells is also a notable achievement. These cells are made of a novel material that has the potential to capture more sunlight and convert it into electricity more efficiently than traditional silicon-based solar cells. The synthesis of the organic compound ethylene glycol, a key component in the production of plastics and textiles, is another significant breakthrough that could have far-reaching implications for industries that rely on this compound.
Overall, the ranking highlights the importance of scientific innovation in driving progress and solving some of the world’s most pressing challenges. These breakthroughs demonstrate the vast potential of scientific research to address global issues such as climate change, health crises, and sustainable development. The recognition of these accomplishments also serves as a reminder of the need to invest in and support scientific research, which can lead to new technologies, solutions, and opportunities for a better future.
