ISRO recently launched the NVS-02 navigation satellite aboard the PSLV-C55 rocket. While the mission was successful, here are some potential challenges and issues related to such launches in general: * Technical Challenges: Launch vehicle failures, cryogenic engine development, and ensuring the satellite reaches the correct orbit are always significant hurdles. * Cost: Space missions are expensive, and cost overruns can be a concern. * Timelines: Delays in development or launch can impact the overall mission timeline. * Data Utilization: Effectively utilizing the data received from the satellite for its intended purpose is crucial. * Space Debris: The increasing amount of space debris is a growing concern for all space agencies, including ISRO. It's important to note that these are potential challenges, and the NVS-02 mission itself was a success.
