| 1. What is the significance of ISRO bringing down the decommissioned weather satellite Megha-Tropiques-1? |  |
Ans. The decommissioned weather satellite Megha-Tropiques-1 being brought down by ISRO holds significance as it helps prevent the satellite from becoming space debris and poses a risk to other functioning satellites. By safely deorbiting the satellite, ISRO ensures the sustainability of space operations and reduces the potential hazards of space debris.
| 2. Why did ISRO choose to bring down the Megha-Tropiques-1 satellite? | |
Ans. ISRO chose to bring down the Megha-Tropiques-1 satellite to avoid the accumulation of space debris. Decommissioned satellites, if left in orbit, can pose a threat to operational satellites and spacecraft. By deorbiting the satellite, ISRO ensures the safety and longevity of space missions.
| 3. How does ISRO bring down a decommissioned satellite like Megha-Tropiques-1? | |
Ans. ISRO brings down a decommissioned satellite like Megha-Tropiques-1 by initiating a controlled reentry process. This involves firing the satellite's onboard thrusters to lower its orbit gradually, causing it to reenter the Earth's atmosphere. Upon reentry, the satellite burns up and disintegrates, ensuring it does not pose a risk as space debris.
| 4. What are the potential risks associated with decommissioned satellites if not brought down by space agencies like ISRO? | |
Ans. If decommissioned satellites are not brought down by space agencies like ISRO, they can become space debris and pose several risks. These risks include collisions with operational satellites, spacecraft, or even the International Space Station (ISS), which can damage or destroy these valuable assets. Additionally, the accumulation of space debris can hinder future space exploration and scientific missions.
| 5. How does the deorbiting of decommissioned satellites contribute to the sustainability of space operations? | |
Ans. Deorbiting decommissioned satellites like Megha-Tropiques-1 contributes to the sustainability of space operations by reducing the amount of space debris. Space debris poses a significant threat to operational satellites and spacecraft, as even small debris can cause significant damage upon collision. By safely bringing down decommissioned satellites, space agencies like ISRO ensure the long-term viability and safety of space missions.
