Sustaining human life in outer space is a challenging undertaking. Despite about 200,000 years on the planet in our current, highly-evolved form, humans have only within the last 60 or so years figured out how to go into space without getting killed.
In part IV, we looked at the need to protect spacecraft from the harsh outer space environment while maintaining comfortable temperatures for crews. In this final part, we’ll explore the challenges surrounding keeping human spaceflight crews fed and hydrated during their missions.
In the last part, we discussed different kinds of propulsion systems that might be used to cross vast distances in space at reasonable periods of time. Now, we’ll look at the need to protect spacecraft from the harsh outer space environment and maintain temperatures that are comfortable for human crews.
In part II, we looked at the need for gravity aboard manned spacecraft, and how we might go about achieving artificial gravity in deep space. In this part, we’ll discuss different propulsion systems that might be used on future spacecraft to cross vast distances in reasonable periods of time.
In part I, we examined the size and design elements of future manned spacecraft. Now we will look at the need for gravity aboard manned spacecraft, and how we might go about achieving artificial gravity in deep space.
In his seminal television series Cosmos, the late Dr. Carl Sagan drew a comparison between the Atlantic Ocean that stood in the way of explorers such as Columbus centuries ago and the limits of outer space as we came to know them in the 20th century.
