In the depths of night aboard the Submarine, apart from sleeping, there's little to do.
Only upon reaching certain stations, when the Submarine performs a personnel exchange and slowly ascends coinciding with the dawn, can one sit in the viewing deck on the first level and take in the breathtaking Star Sky.
Unfortunately, the time for boarding and disembarking from the Submarine isn't long, mostly just about ten or twenty minutes.
Even if the viewing deck reveals a splendid Star Sky, it's just a fleeting moment of beauty.
Only those extremely bored and lonely would linger in the viewing deck during the night, hoping for the Submarine to ascend and get lucky enough to witness the Star Sky as if the Milky Way has fallen to Earth.
During the day, the viewing deck offers much more to see.
Following the ocean currents, one can see various marine creatures also caught in the currents.
