On March 27, 2019 India has tested its first ever Anti-Satellite (ASAT) missile code named as ‘Mission Shakti’. India shot down one of its own Low Earth Orbit (LEO) satellite through a ballistic missile and became fourth country in the world after USA, Russia and China having the capability. ASAT weapons are the space weapons which allow a state to attack opponent space assets which disrupt communication channel. Indian ASAT test translates into New Delhi capability which can be used to destroy opponent satellites. The shooting down of its own low orbit satellite with a ground to space missile has made India a ‘space power’. This technology effects Intelligence, Reconnaissance and Surveillance (IRS) system of enemy state. India has the ambitions to enhance its space capabilities as a part of its Defence Doctrine. This ASAT test by New Delhi touches a number of important issues which endanger the contemporary security environment of South Asia and the international security. At international level it generates a debate on space policy, politics and the weaponization. International community gave different reaction on Indian ASAT test. Indian missile test raised concerns in Pakistan as its security threats mainly coming from eastern border. Pakistan responded that ‘ASAT test should have a matter of serious concern for global community, not only in terms generation of space debris but also because of its consequences for long term sustainability of peaceful space activities’. Bridenstine, administrator of NASA also condemned Indian ASAT test and said that 24 pieces out of 400 debris identified by NASA went above the apogee of International Space System (ISS) which could damage the ISS and other satellites. Russia and China also commended Indian ASAT test. Contrary, US reaction to Indian ASAT was quite supportive but they showed their reservation on debris. Pentagon’s statement in favor of Indian ASAT test shows clearly that US have biased attitude towards New Delhi’s developments. In general, such types of tests have negative impact onexisting ISS. International rules and regulations about the space only stop a state from putting WMDs in the space. But it is a matter of concern that destruction of satellite creates debris which will ultimately affect the space system or other satellite. There should be a treaty which deals with the matter of debris. The crisis between two states started after 14 February Pulwama attacks in Indian occupied Kashmir (IOK) for which India blamed Pakistan. In this intense environment, the ASAT test opens up new avenue for intensification of existing clashes between the two nuclear armed neighbors South Asia security environment is marred with mutual hostility between two nuclear powers India and Pakistan. Owing to this enmity, both the states indulge in arms race. The action reaction spiral governs the arms race between India and Pakistan. This test will also start a new chapter of space race between two states. The timing of the test i.e. 27th March was crucial in the context of existing tensions and aftermath of February 2019 military escalation between Pakistan and India.The crisis between two states started after 14 February Pulwama attacks in Indian occupied Kashmir (IOK) for which India blamed Pakistan. In this intense environment, the ASAT test opens up new avenue for intensification of existing clashes between the two nuclear armed neighbors. This test has strategic as well as political significance. Politically it is significant because soon after two weeks of this test, Indian general elections were going to be held. It can be said that the test was a way to strengthen BJP popularity and to gain right wing support in the elections. Strategically, this test will not only disturb the stability of the region but also increase vulnerability which will ultimately challenge the existing deterrence stability of South Asia. Pakistan considers Indian developments a direct threat to its sovereignty; consequently this test can start a new space arms race in South Asia. Pakistan always in favor of demilitarization of space and tried to controlled arms race in South Asia. Pakistan due to economic constraints faces difficulties to maintain existing strategic balance of South Asia after Indian ongoing conventional and unconventional developments. International community especially US and West has dual standards vis-à-vis India and Pakistan. In this regard, Pakistan should further enhance its collaborations with China which is a time tested friend and strategic partner to maintain strategic stability of South Asian region.
