The idea of a submarine in space is a fascinating thought experiment that merges the depths of our oceans with the vastness of space. But could a submarine, a vessel designed for underwater exploration, survive the harsh conditions of outer space?
Design and Durability
Submarines are marvels of engineering designed to withstand extreme pressure differences between the inside of the hull and the deep-sea environment. They are equipped with robust life-support systems to sustain their crew for extended periods.
However, these features cater to an environment rich in pressure, quite the opposite of the vacuum of space.
A Vacuum Versus Pressure
The vacuum of space presents a stark contrast to the high-pressure environment of Earth’s oceans. While submarines are built to withstand high external pressures, space requires a vessel to maintain internal pressure without external support.
This reversal of pressure dynamics poses a significant challenge for any submarine-like spacecraft.
Life Support in the Void
Life-support systems in submarines recycle air and manage carbon dioxide levels, akin to spacecraft. However, space travel requires protection against extreme temperatures and cosmic radiation, threats that submarines are not designed to handle.
Navigational Necessities
Submarines navigate through water using propulsion systems that rely on the medium of water to function. In the absence of water or any substance to push against, traditional submarine propulsion systems would be ineffective in space.
The Final Verdict
While submarines are unsuitable for space as they are, the concept isn’t entirely out of depth. With modifications to manage internal pressure, temperature control, and an appropriate propulsion system, a submarine-inspired spacecraft could potentially be engineered for space exploration.
However, as it stands, a submarine is a vessel of the seas, not the stars.
