Recently, the US National Aeronautics and Space Administration or NASA It has announced a grant of approximately 22 million baht to study the possibility of sending a small swarm of swimming robots to explore the oceans beneath the icy crust of other planets in our solar system. "World of Oceans"
Oceans on other stars are of interest to scientists because of their chemical reactions.
Between rocks and sea water can support life.
And these ocean environments may be similar to the ocean environments on Earth at the time life began.
Pluto is an example of
"World of the Ocean", but the land with the ocean closest to the surface of the star
And believe that the most accessible is Europa.
Jupiter's moons
and Enceladus
Saturn's moon
Enceladus' oceans were sampled by the Cassini spacecraft.
That ended itself never to return in September 2017, leaving a rich legacy of valuable information in Saturn's exploration.
The idea of an autonomous swimming robot called Boaty McBoatface that scientists envisioned was
When the spaceship landed on Europa
or Enceladus
This is not so easy because the ice on the planet is quite thin.
The spacecraft will use radioactive heating devices to drill holes 25 cm across the ice and then launch a tiny, wedge-shaped, 12cm long robotic swimmer to explore hundreds or thousands of miles in the ocean beneath the ice crust. thousand meters
The robot communicates with the device above through sound waves.
And that device transmits data via cable to a spacecraft landing on the star's surface.
