this is bbc news, the headlines. nasa scientists have successfully managed to test the world s first planetary defence system by deliberately crashing a spacecraft into an asteroid. the dart mission is the first test of a technique which could one day be used to defend earth from an approaching space rock. the kremlin has admitted mistakes in the way it has tried to mobilise hundreds of thousands of russian reservists to fight in ukraine. the call ups have triggered widespread protests after reports that the disabled and people with no military experience were being handed draft papers. the un s special representative in haiti has said an economic crisis, a gang crisis and a political crisis have converged into a humanitarian catastrophe. haiti s latest wave of protests was triggered by the government s decision to end fuel subsidies. now on bbc news,
dart really is just the start. it s just the first planetary defence test mission. it was spectacular and it s accomplished and we ll figure out how effective it was that s really what we re going to learn in the next weeks to come. all right, we hit this asteroid now, how effective was that at deflecting it and what would that mean for using it? the damage asteroids can do is well known the biggest ones could cause global devastation, like the space rock that wiped out the dinosaurs 66 million years ago. the challenge is to find them early enough, so a mission to divert could be carried out well in advance. the dart mission is the first step in finding a solution, and in the coming days and weeks, scientists will be assessing whether their test has been successful. it s a demonstration of a technology that could one day save our planet. rebecca morelle, bbc news. how you re feeling a bit safer this
