This brass octet was commissioned by Tokai University Takanawadai High School. Cassini is a Saturn probe launched in 1997. It took seven years to reach Saturn's orbit, and for another 13 years, it explored Saturn and its satellites and brought many discoveries to humankind, but finished its role last year (2017) and finally entered Saturn's atmosphere. It burned out and fulfilled its role. This work summarizes the events in the middle of Cassini's long journey in 5 minutes.

For a total of four times "swing-by" changed the flight path using the gravitational pull of celestial bodies to accelerate and correct its orbit with Venus, Earth, and Jupiter. After reaching Saturn's orbit in seven years, the probe made landfall with a small probe on the surface of Titan, covered in thick atmosphere. In Enceladus, one of the satellites, Cassini passed through the steam erupting from underground and detected substances implying the possibility of life. It also passed between Saturn's body and the ring, photographed the ring from the inside, and sent detailed data on its structure to Earth. In the end, a mission called "Grand Finale" was carried out and it burned out in Saturn's atmosphere.

Mainly the above scenes are expressed with rhythms and phrases, and this piece features a brilliant brass sound.
