  The past decade has witnessed an unprecedented development of deep-sea science and technology in China. If the pace will be kept for the coming decade, China will enter the global frontiers in deep-sea exploration with historical contributions to the world science. The deep sea is the largest habitat on the planet, yet its eternal darkness and hostile environment present tremendous challenges to the deep-sea developers. Since China has reached a crossroads in its deep-sea research, it is essential to learn from the history in planning and its implementation, and to avoid the pitfalls on the journey.

  2020 was an important year of deep space exploration for China, during which the first Chinese independent Mars mission Tianwen-1 and the lunar sample return mission Chang'E-5 were successfully launched. Tianwen-1 has combined three important functions:orbiter, lander and rover into one. Chang'E-5 is the first mission for China to return samples from other celestial body. On 17 December, it brought back 1.731 kg lunar sample successfully. 2020 was also a lunching window for Mars, which occurs every 26 months. In that window two other missions were also launched, i.e. the UAE's Hope Mars orbiter and the US's Mars Laboratory Perseverance. When deep space exploration became a focus of world attention, it is necessary to review the history and plan the future. This paper briefly reviews the history of human deep space exploration, discusses the scientific motivation and technical challenges. In particular, it discusses the sustainability of deep space exploration, and puts forward some relevant suggestions for the future development of China's deep space exploration.

  In the past few decades China has made significant achievements in science and technology. In recent years, disturbances in international relationships have brought to China warnings and new requirements about how to better develop science and technology. For forward-thinking, new changes are needed for the training and evaluation system of sci-tech talents in the new era. It is essential to build a comprehensive and independent system of scientific education, to establish an Englishspeaking research environment in top universities, and to support more Chinese scientists to participate in international scientific collaborations and communications. These measures will provide important support for the long term, healthy development of science and technology in China.

  Improving population policy and promoting family patterns of respecting the aged, caring for the young and intergenerational assistance

  ZENG Yi

  Science & Technology Review. 2021, 39(3): 130-140. https://doi.org/10.3981/j.issn.1000-7857.2021.03.013

  The present article aims to demonstrate the significance, necessity and feasibility of improving population policy as well as promoting the family pattern of respecting the aged, caring for the young and intergenerational assistance. Our scientific analyses show that the policy of returning the fertility decision-making to families and encouraging the second birth would not lead to over-growth of population. On the contrary, such policy improvements would be helpful to slow down the quick shrinking of labor resources, face the serious challenges of population ageing, and so on. Our empirical analyses on the "Chinese Longitudinal Healthy Longevity Survey" datasets demonstrat that family pattern of three-generations living together or living nearby may not only improve the health of the elderly but also strengthen the household assistance by older parents to their children to realize the "win-win" outcome. Based on our solid scientific research, we suggest to implement the policy of returning the fertility decision-making to families and encouraging the second birth as soon as possible. We suggest to promote the family pattern of respecting the aged, caring for the young and intergenerational assistance to facilitate national development and the well-being of hundreds of millions of families.
