ESO Transmission #20.1 - Water World on Gliese 163 c
Recovered archive from ESO Exploratory Space Organization.
Mission 20 marked another long-range planetary survey conducted by the ESO Exploratory Space Organization, humanity's most experienced deep-space exploration agency specializing in potentially habitable exoplanets.
Unlike the early decades of exploration, extraterrestrial environments were no longer unfamiliar to ESO crews. Following earlier expeditions to worlds such as Gliese 667 Cc, the organization had already completed numerous successful landings on distant planets, documenting alien plants, marine organisms, atmospheric ecosystems, and planets remarkably similar to Earth.
The twentieth expedition targeted Gliese 163 c, an exoplanet located approximately 49 light-years from Earth.
Long-range observations suggested an extraordinary discovery. Rather than containing continents and oceans like Earth, Gliese 163 c appeared to be an immense water world. Every visible region of the planet was covered by a single uninterrupted global ocean.
The primary objective was straightforward: obtain uncontaminated seawater samples for laboratory analysis before returning to orbit.
Veteran astronaut and ESO tactical specialist David Morgan was selected once again to perform the solo surface operation, a role he had successfully completed on numerous previous expeditions across multiple star systems.
Initial atmospheric analysis detected approximately 3% oxygen, confirming that although the environment could not support human respiration without life-support equipment, biological processes were likely occurring somewhere beneath the endless ocean.

Surface Entry - Landing on an Endless Ocean
At 08:16 UTC, David separated from the main exploration vessel aboard an advanced single-pilot atmospheric craft specifically engineered for aquatic planetary operations.
Unlike conventional landing modules, the vehicle was capable of floating directly on deep oceans while maintaining complete stability against strong waves and unpredictable currents.
Several minutes later, the spacecraft settled gently onto the calm surface of Gliese 163 c.
The first visual report surprised even experienced ESO researchers.
The sky was bright blue. White clouds drifted slowly overhead, while the ocean reflected deep sapphire colors almost identical to Earth's tropical seas.
From the cockpit, the horizon appeared endless.
No islands.
No continents.
No visible land in any direction.
Only water extending beyond the limits of every optical sensor.
"It feels like Earth forgot to create continents."
— David Morgan, Mission Log #20-01
Mission Objective - Collecting Ocean Samples
After confirming stable conditions, David activated the spacecraft's automated extraction system.
Four reinforced scientific storage containers were lowered beneath the hull before pumps began collecting seawater directly from the planet's global ocean.
Real-time analysis indicated unusual mineral concentrations and microscopic organic compounds unlike any marine chemistry previously documented within the ESO archive.
The water itself appeared exceptionally clear, allowing onboard cameras to observe remarkable depths before sunlight gradually disappeared into darkness.
Despite the peaceful conditions, sonar systems failed to detect the ocean floor.
Every measurement exceeded the maximum scanning range of the spacecraft.
Gliese 163 c possessed an ocean far deeper than any found on Earth.
Unexpected Hazard - Planetary Scale Tsunami
As the fourth and final sample container reached maximum capacity, the spacecraft's threat detection system suddenly emitted a continuous emergency alarm.
Every warning display illuminated simultaneously.
Automatic navigation immediately recommended emergency ascent.
David looked through the forward observation window.
Far across the horizon, an enormous wall of water was rapidly rising above the otherwise calm ocean.
Within seconds, onboard calculations estimated the approaching wave to be vastly larger than the greatest tsunamis ever recorded on Earth.
Its height continued increasing as though an entire section of the ocean itself had been lifted into the sky.
The cause remained completely unknown.
No asteroid impact.
No detectable seismic event.
Only a colossal moving wall of water advancing across the planet's endless sea.
"That's not a wave... that's an ocean standing up."
— David Morgan, Emergency Log #20-07
Emergency Escape
David immediately terminated all collection procedures.
The extraction equipment detached automatically while the four sealed gallons of seawater were secured inside the spacecraft's protected laboratory compartment.
Within moments, the engines reached full thrust.
The small exploration craft accelerated vertically just as the towering tsunami swept across the previous landing position.
Camera recordings captured an immense curtain of water consuming the entire area beneath the ascending spacecraft.
Had the launch been delayed by only a few additional seconds, both the vehicle and its pilot would almost certainly have disappeared beneath the unimaginable force of the planetary wave.
Recovery Log
David successfully returned to the primary ESO expedition vessel carrying all four seawater samples intact.
Although Mission 20 achieved its primary scientific objective, the unexpected tsunami immediately elevated Gliese 163 c to one of the highest-priority research targets within the ESO planetary archive.
Scientists continue analyzing the recovered water in an effort to determine what mechanism could generate ocean waves on a scale never before observed by humanity.
For now, one conclusion appears certain.
Gliese 163 c may resemble Earth beneath its blue skies and white clouds, but its ocean obeys forces far beyond anything experienced on our home world.
