Overview of the PSLV-C37 Mission

• released on February 15, 2017, with the primary satellite being Cartosat-2D.
• It confirmed that ISRO is still the preferred choice for satellite launches.
• Place the top stage (PS4) in an orbit that is 494 kilometers wide and 470 kilometers high.
• The object, NORAD 42052, had re-entered, and a good deal of monitoring indicated that it was returning to Earth.
• The upper stage's orbit has shrunk to around 134 km by 148 km as of October 6, 2024.
• ISRO did adhere to the global standard to reduce space debris upon re-entry.
• In five years or fewer, PSLV's upper stages will be deorbillated; ISRO is working on this.
