Yes, there are several reasons why ISRO is planning to launch Aditya-L1 even though NASA has already launched the Parker Solar Probe.
- Different perspectives:
The Parker Solar Probe will fly much closer to the Sun than Aditya-L1, which will allow it to study the Sun's atmosphere in unprecedented detail. However, it will not be able to see the Sun's entire surface at once. Aditya-L1, on the other hand, will be able to see the entire Sun, but it will not be able to get as close as the Parker Solar Probe. This means that the two missions will complement each other, providing a more complete picture of the Sun.
- Different instruments: The Parker Solar Probe and Aditya-L1 carry different instruments, which means that they will be able to measure different things. The Parker Solar Probe's instruments are designed to study the Sun's atmosphere, while Aditya-L1's instruments are designed to study the Sun's magnetic field and solar wind.
- Different capabilities:
The Parker Solar Probe is a much more complex and expensive mission than Aditya-L1. It is also a much riskier mission, as it will be exposed to much higher temperatures and radiation. Aditya-L1 is a more affordable and less risky mission, which makes it a good option for ISRO, which has a limited budget.
- National pride:
There is also a sense of national pride in ISRO's Aditya-L1 mission. ISRO is India's space agency, and the Aditya-L1 mission is a major milestone for the agency. It is a sign that India is capable of carrying out cutting-edge space missions.
