Why do we need to think about redirection of a space object & why now? DART - Deep dive & learnings from it
DART - Also an acronym for Double Astroid Redirection Test. Every planetary and non-planetary object revolves around the sun and for the major part their axees never intercept. But what if one day that happens - is there a way to get around it? (it's not expected to happen in next 100 years though). That's the question - this mission exercise is hoping to answer. DART is basically targeting an astroid which will not be hitting earth but will be the right candidate(s) in terms of size and placement to allow for testing a decisioning system to make that change for it to deflect from it's intended virtual path of intercept. Before we can talk about the way in which this is being actioned, let's understand how we identify an incoming astroid impact. The simple way is to take pictures and understand the relative positions of the objects moving in the sky. The stars don't move, but the planets and small bodies do which includes astroids. First identify - if it's mo...
