family sure when it's at one of the protests in russia's capital moscow or bring her in now emily what is the message that the protest protesters want to send. well my other stretches just taking place under the water that somebody declared out of the protest and that is he's not. this protest is very much directed act which in the head of his inauguration and the head of the head of the project. basically said you know who should be able to move us like a king or not his peasant. people came out today really to fight for their rights as citizens they told me they said that they're sick of the restrictions that the state is putting on them the restrictions on freedom of speech on the media on the internet and they hear there were a lot of arrests and people were also chanting against what they see. is the police

as the police state here and now people have been burned by by the police but protesters seem to have returned to the main square to pushkin square at a kind of gathering around. statue there are the pictures we're looking at now make it look pretty rough now of all the sort of in the linchpin in all of these protests has his attention had an impact on the mood there was a pretty much expected. well his arrest was certainly to be expected in fact i saw on social media several users sharing the information that now finding had come to the protests had arrived at the protests and basically writing ok the countdown now starts when he's going to be arrested after all of this is not the first. protest that's not by any has a range this year he also writes some ahead of the elections and it was it wasn't

unusual for him to be arrested at those protests now the mood did shift a little bit after he was arrested it seems to me that the police presence got much larger after he was arrested and the police started dispersing people surrounding the crowd pushing them sort of off the main square but it does seem that people have returned there now he said people have returned after being pushed out how large are the crowds of this point now that it's been going on for a little while and are people scared of the police or are they pushing forward. well certainly the crowds now are much smaller in fact i would say usually the crowds were fairly mixed but there were certainly several hundred people baby even over a thousand it's hard to judge of course. how many exactly and now it's. just perhaps a hundred or. so protesters that remain at it or they don't people who have come back but of course you know it is intimidating if you see the police president

present here and people were being even pushed by the police the crowd who really pushed with a lot of force various police units out here on the streets riot police special police forces as well and they were widespread arrests i thought of basically blasting people out of the crowd and putting them into police cars just as they walked along. emily sure went for us in moscow thank you very much for your reporting. the u.s. space and it's a nasa has launched its latest probe to mars a powerful atlas five rocket is propelling the mars insite lander to the planet's surface as we speak the journey is expected to take six months upon arrival the pro will be looking deep under the planet's crust for clues about how it was formed with. the inside lander will be the first to examine the internal structure

of the planet mars scientists have been eager to gather data on the red planet's interior for decades. we know a lot about the surface of mars we know a lot about its atmosphere and even about its saw on a spear but we don't know very much about what goes on a mile below the surface much less two thousand miles below the surface down to the center this heat probe should be able to fill in some of those gaps developed by scientists at the german aerospace center it will measure the temperature of individual underground layers and determine how efficiently these layers conducts heat to do this the probe will have to grow deeper into mars surface than any previous drill. another instrument will monitor how much mars north pole wobbles as it orbits the sun. and for the first time a seismometer will measure seismic five gracious on mars surface caused by

earthquakes and meteor strikes the data acquired by all three experiments will make it possible to make new suppositions about the inner structure of mars and the information will help scientists to reconstruct the early development of rocky planets such as the earth mars venus and mercury. this will allow them to look back in time to when the super heated elements separated according to their densities and formed layers in the young planets. the structure of the planets consists of a dense missile. less dense mantles and a rocky outer crust formed as the planets cooled. on mars this process appears to have been faster and indeed earlier than on earth there even today we can see the traces of do certainly development things on the earth these

traces have been almost completely obliterated. now into some of the other stories making news around the world voters in lebanon are gearing up for their first parliamentary election in almost a decade hopes are high that the vote on sunday will end a prolonged political gridlock in forming a government could take months or even longer in part due to the country's complex party system. thousands of people are on the streets of paris today to protest government policies marking a year since president election his critics say his economic and social reforms favor the wealthy and corporations by abolishing some worker protections and increasing police powers smaller rallies also took place in toulouse and bordeaux. north korea has adjusted its time zone by half an hour to mass that of south korea is the latest in a series of steps aimed at thawing relations between the two countries but some koreans remain wary of the thaw shut down activists who tried to launch anti regime
