NASA’s Cassini spacecraft has had its final shut brush with Saturn’s moon Titan and transmitted images showing unusual objects near Saturn’s hazy moon earlier than its ultimate set of 22 orbits across the ringed planet.

The spacecraft made its 127th and ultimate shut strategy to Titan on April 21 at 11:08 p.m. PDT (2:08 a.m. EDT on April 22), passing at an altitude of about 608 miles (979 kilometers) above the moon’s floor.

The flyby additionally put Cassini on track for its dramatic final act, often called the Grand Finale. The mission will conclude with a science-rich plunge into Saturn’s environment on Sept. 15, 2017.
