Shenzhou-18 taikonauts to create simplified version of aquatic ecosystem Xinhua
sdgtalks
Introduction
This report discusses the unique task undertaken by the taikonauts aboard China’s Shenzhou-18 spaceship to create an “aquarium” and raise fish in zero gravity. The purpose of this experiment is to study how the space environment affects the growth and system balance of zebrafish and algae, which will be used to create a simplified version of an aquatic ecosystem.
Experiment Details
The taikonauts have entered the country’s space station and met with another taikonaut trio, marking the start of a new round of in-orbit crew handover. As part of their mission, they will create a backup version of the aquatic ecosystem and set up the aquarium in space.
Aquatic Ecosystem Setup
- Creating a simplified version of an aquatic ecosystem
- Using zebrafish and algae
Task Significance
This experiment aligns with the Sustainable Development Goals (SDGs) set by the United Nations. It contributes to Goal 14: Life Below Water, by exploring the impact of zero gravity on aquatic life and ecosystem dynamics. Additionally, it supports Goal 15: Life on Land, as the findings can provide insights into the potential challenges and opportunities for sustaining life in extreme environments.
Conclusion
The taikonauts’ mission to create an “aquarium” and raise fish in zero gravity is a significant step towards understanding the effects of space on aquatic ecosystems. By studying zebrafish and algae in this unique environment, valuable insights can be gained for the advancement of space exploration and the sustainable development of life on Earth.
SDGs, Targets, and Indicators
-
SDG 14: Life Below Water
- Target 14.1: By 2025, prevent and significantly reduce marine pollution of all kinds, in particular from land-based activities, including marine debris and nutrient pollution.
- Indicator: The article mentions that the taikonauts will study how the space environment affects the growth and system balance of zebrafish and algae in a simplified version of an aquatic ecosystem. This research can contribute to understanding the impact of the space environment on aquatic life and potentially inform efforts to prevent pollution and maintain the health of marine ecosystems.
-
SDG 15: Life on Land
- Target 15.5: Take urgent and significant action to reduce the degradation of natural habitats, halt the loss of biodiversity, and protect and prevent the extinction of threatened species.
- Indicator: The article mentions that the taikonauts will create a simplified version of an aquatic ecosystem using zebrafish and algae. This research can contribute to understanding how the space environment affects the growth and balance of these species, which can inform efforts to protect and conserve threatened species and their habitats on Earth.
