Before living on the moon, get ready to call a submarine your home


Submarines are becoming an innovative research platform for studying human adaptation to extreme environments, including the depths of the ocean and the vastness of space.

The European Space Agency (ESA), in collaboration with the Portuguese Space Agency and the Portuguese Navy, has launched the SubSea project, which aims to recreate the isolation and confinement challenges faced by astronauts during long-duration space missions.

The first crew of the SubSea project returned to shore after completing a rigorous 60-day underwater expedition.

This mission involved 25 volunteers living in cramped quarters, simulating conditions similar to those experienced by astronauts. A scientific team from universities in Germany, Italy, and Portugal is analyzing how stress, mood, and crew dynamics evolve in such confined environments.

 Submarines provide an ideal setting for this research, as they replicate many operational challenges of space missions. The data gathered during these underwater expeditions will help develop strategies to support crew members during future human spaceflight missions.

Scientists utilised questionnaires and collected biological samples, such as hair and saliva, to monitor stress markers like cortisol and assess changes in immune health throughout the mission.

ESA astronaut Andreas Mogensen emphasised the importance of projects like SubSea in preparing for the physiological and psychological challenges of space travel. “SubSea is an essential initiative to understand human resilience in extreme environments,” he stated.

As Portugal positions itself as a hub for space research and innovation, it leverages its unique terrestrial and marine resources. The country boasts several terrestrial analogue sites that resemble conditions found on celestial bodies like the Moon and Mars.

The findings from the SubSea project will not only enhance our understanding of human adaptation but also have implications for various fields, including healthcare for isolated populations and military deployments.

This mission marks an important step toward preparing for future explorations to the Moon, Mars, and beyond.

  Dengue Surge Linked to Climate Change      Dengue fever cases are at record levels worldwide, with studies linking 19% of the rise to climate change, which is expected to worsen by 2050. Predictions indicate a potential 40-60% rise in cases, with some areas facing increases of 150-200%. Current Global Context      Recently, nearly 12 million dengue cases were reported in the Americas. This marks an important rise from 4.6 million in 2023. Locally acquired infections have emerged in California and Florida. India is also experiencing a surge in cases. Research Findings      Researchers from Stanford and Harvard conducted a study on dengue incidence. They analyzed data from 21 countries in Asia and the Americas. The results show a direct correlation between rising temperatures and increasing dengue infections.      Dengue can cause mild to severe symptoms. Severe cases may lead to bleeding and shock. There are no specif...

  Clean Ganga Mission to Start Dolphin Ambulance      The National Mission for Clean Ganga (NMCG) is actively promoting conservation efforts and targeting the Ganga River’s biodiversity. They focus particularly on endangered species like the Ganga Dolphin . Recent developments include the introduction of a Dolphin Ambulance. This vehicle will aid in rescuing injured dolphins, which are crucial to the river’s ecosystem. Dolphin Ambulance Initiative      The Dolphin Ambulance project is titled Advancing Rescue System for the Protection of Stranded Ganges River Dolphins, which has a budget of Rs 1 crore. The ambulance will provide immediate care to injured dolphins. The initiative aims to enhance public awareness about dolphin conservation. Training will be provided to local communities. This training focuses on the effective management of dolphin-related issues. Additional Conservation Projects      NMCG has approved several other proje...
