Upper Stage of PSLV-37 rocket enters earth's atmosphere as predicted: Isro

This requirement was met by properly designing a passivation sequence which lowered the orbit of PS4 after the injection of the payloads

The upper stage of PSLV-37 rocket, which launched a record number of 104 satellites more than seven years ago, has re-entered the earth's atmosphere as predicted, the Indian Space Research Organisation announced on Tuesday.

PSLV-C37 was launched on February 15, 2017 with Cartosat-2D as the main payload along with another 103 satellites as co-passengers. It created history as the first mission to launch 104 satellites with a single vehicle, the Bengaluru-headquartered national space agency noted in a statement.

After injecting the satellites and passivation, the upper stage (PS4) was left at an orbit of approximately 470 x 494 km
