Scientists use heart and lung model to calculate potential health threats facing future space tourists in microgravity
Friday, 21 June 2024 03:00
Space exploration has always captivated our imagination, offering the promise of discovering new worlds and pushing the boundaries of human capability. As commercial space travel becomes more accessible, individuals with various underlying health conditions—including heart failure—may soon be among those venturing beyond Earth's atmosphere.
This raises critical questions about the impact of space travel on humans with potential underlying health problems. Recent research, "Computational modeling of heart failure in microgravity transitions," delves into this issue, offering insights that could shape the future of space travel.
Why study heart failure in space?
The demographic of commercial space travelers is shifting, increasingly including older, wealthy individuals who may not be in optimal health. Unlike professional astronauts, these space tourists typically do not undergo rigorous health screenings or physical training. This shift necessitates a broader consideration of health conditions, such as heart failure, diabetes, and other chronic illnesses, in space mission planning.
Heart failure alone affects over 100 million people globally. Traditionally, space medicine has focused on the effects of microgravity on healthy astronauts. However, the inclusion of non-professional astronauts with preexisting health conditions demands a deeper understanding of how microgravity impacts these individuals.

If liquid water exists today on Mars, it may be too deep underground to detect with traditional methods used on Earth. But listening to earthquakes that occur on Mars - or marsquakes - could offer a new tool in the search, according to a team led by Penn State scientists.
