What is the name of the operation under which India successfully conducted its first anti-satellite (ASAT) missile test?

Explanation

Mission Shakti. Conducted on March 27, 2019, by DRDO, this test made India the 4th country (after US, Russia, China) to achieve ASAT capabilities; Mission Indradhanush refers to both universal immunization (health) and public sector banking reforms. Astra is India’s indigenous Beyond Visual Range (BVR) Air-to-Air missile, while Operation Smiling Buddha (1974) was India’s first nuclear test. India also uses Project NETRA for space debris tracking and orbital safety.
