Science- India just tested is anti-satellite weapon (ASAT) by taking down a live satellite in low earth orbit.
- While this may make India a 'space power', it weakens its fight against dangerous space debris.
- In the past, Russian satellites have been destroyed by space debris that was left behind by China's testing of its ASAT.
And, while this gambit adds India to the list of the select few nations to have done so successfully, it’s out of place with India’s role as a member of the Inter-Agency Space Debris Coordination Committee (IADC).
As a member of IADC, such a test by India could undermine the country’s credibility in the arena.
India is also a signatory of the Outer Space Treaty which prohibits the use of weapons in space and requires nations to take steps to mitigate space debris. With respect to the first part Kumar Abhijeet, a member of the International Institute of Space Law (IISL) clarifies, "If we look up the international treaty. Nowhere is ASAT testing prohibited. We are very much within the international laws to make use of it."
But, in cases where space debris is created, nations are under the obligation to pay compensation for any damages that arise from it.
When China tested its ASAT capabilities back in 2007, the test left behind 2,500 to 3,000 pieces of dangerous space debris in Earth’s low earth orbit (LEO). And despite never ending perception of space, debris in that particular region is a threat to other satellites.
A Russian satellite was one such victim in 2013, when a piece of space debris struck the body of the satellite, destroying it.
And, the question is not solely about space debris destroying other satellites. It's also about how space debris can result in more space debris as it knocks into older objects left behind in space. The true danger is that some of these pieces of debris are so small that it's nearly impossible to track them.
Unlike China, where the test was conducted at an altitude of 800 km, India's ASAT test was conducted only 300 km above the Earth where the probability of space debris is unlikely.
'Operation Burn Frost' was conducted in a similar manner at an altitude of 240km. Even then, while most of the debris managed to fall back to Earth within a year, a few pieces were still blasted to a higher orbit.
To prove it’s military might in space, India had the option of conducting a fly-by test where, instead of destroying a live satellite, the missile would just glide past.
A former Integrated Defence Staff Lieutenant General, HS Lidder, saw this coming when he said, “With time, we will get sucked into the military race to protect space assets and inevitably there will be a military contest in space. In a life and death scenario, space will provide the advantage.”
