Major Events
On January 29, 2025, the GSLV Mk II successfully launched the NVS-02 satellite. However, post-launch, ISRO reported that orbit-raising operations could not be carried out due to a valve malfunction in the satellite's propulsion system, preventing it from reaching its designated geostationary orbit.

Summary
A rocket body, also commonly referred to as an upper stage or spent rocket stage, is the structural shell left behind after a rocket has delivered its payload to orbit. These large and often heavy pieces of space hardware can remain in orbit for years, posing significant collision hazards as part of the growing space debris problem. If left uncontrolled, rocket bodies have the potential to reenter Earth's atmosphere unpredictably, which can lead to falling debris in populated areas. Additionally, they risk colliding with operational satellites or the International Space Station, creating more debris and putting human life at risk.
