Hello im vishala sri pathma. The Ministry Of Defence has confirmed to the bbc that it will provide the support of armed soldiers to the metropolitan police, after a large number of Firearms Officers handed in their weapons. They turned in their firearms permits after an armed officer was charged with the murder of 24 year old chris kaba who was shot and killed in south london last year. Earlier, the Home Secretary, Suella Braverman, ordered a review of armed policing. Joe inwood reports. Chris kaba was unarmed when he was shot and killed in streatham. He was driving a borrowed car. According to police, the vehicle had previously been linked to an incident involving a gun. Chris kaba was hit by a single bullet, fired by a Police Officer. There was widespread outrage at his death, especially amongst londons black community. Last week, his family were in court to see a Police Officer, who is only being referred to as nx121, charged with murder. They welcomed the prosecution, but its been met with concern by many of the officers colleagues. There are more than 6,000 Police Officers in the uk authorised to carry a firearm, and many of them work in london, in some of the most sensitive parts of the capital. Now its thought around 100 of them have said that they no longer want to carry a gun. 0ne former officer says hes not surprised. I was on armed response for 23 years, i was on vip protection, and i hugely enjoyed the professionalism, the teamwork of it, and i would miss that. Would i put my weapon down today . Yes, iwould hand it in. Its not worth it. Announcing a review, the Home Secretary said Police Officers have to make split second decisions under extraordinary pressures. They mustnt fear ending up in the dock for carrying out their duties. Officers risking their lives to keep us safe have my full backing. It has been confirmed that the army will be helping to fill the gaps, but only as a contingency. At a time when there are calls for increasing scrutiny of the police, especially when it comes to dealing with minority communities, there will be many who see this as an attempt to reduce accountability rather than a welcome reset. Officers from other forces have now been drafted in to help Patrol London a job the Police Federation admits comes with responsibility but also accountability. Joe inwood, bbc news. 0ur Correspondentjoe Inwood outlined the significance of the mods statement of support for the police. To clarify, we shouldnt be expecting to see soldiers on the street. This is not a question of the Army Stepping in to do what we would think of as everyday policing roles. Theyre not going to be arresting people. This will be a contingency service, Contingency Role. I spoke to the Ministry Of Defence earlier, and what they were saying is that there are there are armed, as people would expect. There are armed teams that are ready to respond, for example, to a terrorist incident, a live shooter event, that sort of thing, and those sorts of roles. The kind of in extremist roles will be filled by the army if required. So i think we shouldnt get carried away in saying that the police are going to be replaced by the army. Thats not the case. What were seeing here is a Contingency Role for the army, but it is significant nevertheless. And its interesting because we heard from Suella Braverman and in her statement, theres clearly a lot of support there for the police. Yeah, i think this is really interesting. I mean, here in the uk, weve been seeing a real debate at the moment over the last few years as we have around the world, around the role of policing and specifically the use of force as some would see it, Excessive Force against certain communities here in london, particularly the black the afro caribbean community. And the debate really has been around whether the police are scrutinised enough. What i thought was interesting about the statement from Suella Braverman today, the Home Secretary in the uk was the fact that she was clearly saying that she supported the police. She thought that actually there was a problem here, that the police werent being able to do theirjob because theyre overly scrutinised. So i think were going to be seeing a real tension here between the side of society that thinks that the police maybe dont always act in the best interests of all communities and of all people and the other side, which thinks that maybe Law And Order is more of a priority and would like to give their full backing to the police. And i think the Home Secretary has quite clearly stated in launching this review where she views the argument to to lie, as it were. A capsule containing Asteroid Samples which scientists hope could help explain how Life On Earth began has successfully landed in the united states. The nasa spacecraft dropped the canister carrying just 250 grams of rock and dust from the surface of the asteroid onto the us state of utah. As our science editor, rebecca morelle, reports. On their way to recover the capsule that has travelled billions of miles through space called osiris rex. Which descended towards the utah desert, a view of its parachute slowing the craft. Finally, it is down. Inside is the most precious sample, fragments of an asteroid called bennu that could reveal the secrets of our solar system. The scientists think there are about 250 grams of dust and rock and every grain is precious. Some of our instruments literally look at the items that make up the look at the atoms that make up the crystals inside of these rocks. When youre working at that scale a single stone is the universe to explore. A first glimpse of the capsule thats traveled billions all of this effort is to solve the mystery of what asteroid bennu is made of. This is vital, because bennu tops the list of nasas most hazardous space rocks, so studying its makeup could help us to stop it if we ever need to. But it could also reveal more about our origins its a perfectly preserved relic from the dawn of the solar system. This was the moment the sample was collected in a five second smash and grab, before it was safely stowed in the capsule for its return to earth. The rock and dust will be divided up between scientists around the world, including the team at londons Natural History museum. Were unbelievably excited to see what its going to be made of. I mean, weve thought about it, weve talked about it, weve written papers about it, weve dreamt about what its going to be. And finally, were actually going to see it and find out what it really is, which, yeah, at the moment we have no idea. So its going to be just so exciting to open the canister and find out whats in there. The main concern now is contamination. The team here in utah dont want whats on the ground the dirt, the dust, the microbes to get mixed up with the bits of bennu. Its vital that their invaluable sample is kept pristine. The race is now on to safely recover the capsule. 0pening it up will be a painstaking and slow process, taking several weeks, but Scientists Say the wait will be worth it. Rebecca morelle, bbc news, utah. Ive been speaking with dr Meenakshi Wadhwa planetary scientist at Arizona State university. She also serves as the principal scientist for the mars Sample Return programme. I asked her about the process from here. Its going to be a very, very careful process of documenting the Sample Return capsule. Theyre going to be taking their time before they open it up. They want to make sure that the exterior is completely documented, that they remove any any of the utah dirt that might be attached to the capsule. And then, of course, theyre taking some close up pictures, some images of the capsule itself before they start to open it. And in terms of dust, i mean, how much dust would Something Like this, this sort of meteorite carry . Yes. So this is actually obviously samples from asteroid bennu and the estimate is that there could be as much as 250 grams or so, perhaps even more of sample from the asteroid bennu inside this capsule, inside of the canister. And that will take a while then to presumably navigate through and to extract. Yes, exactly. So, i mean, theyre inside a makeshift clean room right at the close to the landing site at the current time. But they will basically put it under nitrogen at some point and carry it to theJohnson Space centre, hopefully tomorrow. And thats where its going to be taken apart very, very carefully. Now, people might not have been aware of this going on in terms of the significance of this programme. Can you just explain a little bit about the magnitude of whats at stake here . This is an incredible achievement. I mean, this is, of course, the very first Sample Return from an asteroid by the united states. There have been two other Sample Returns from the Japanese Space Agency before this, but they brought perhaps about a teaspoon full of asteroidal materials back. And were hoping were going to get close to a teacup full or so of samples from this one. And its from an asteroid thats thought to be very carbon rich, that may have other volatiles like water, etc. , in the material. And were hoping to learn something about the very beginnings of our solar system, the very beginnings perhaps of life on our planet, whether materials like bennu could have contributed to the complement of organics and volatiles on the early earth that contributed to the origin of life on our planet. We hope to speak to our correspondent in utah a bit later on. Returning now to the uk. And the defence secretary, grant shapps, says it would be crazy not to look again at the rising cost of the hs2 rail project. A decision on whether the government will scrap the birmingham to manchester section of the line is expected this week. Noor nanji reports. Its a grand project first dreamt up in 2009. The aim to Speed Up Journey Times and create more capacity. But hs2 has faced delays, cuts and spiralling costs. The original plan would have connected london to birmingham, and then leeds and manchester. In 2021, the section from birmingham to leeds was cancelled. Now theres speculation the line might end in west london, rather than going all the way to euston, and the birmingham to manchester it is in doubt as well. The last official estimate on hs2 costs, excluding the cancelled eastern section, added up to about £71 billion, although this was in 2019 prices. £22. 5 billion has already been spent on the london to birmingham leg, whilejust over £2 billion has been spent on preparing for the other sections. This morning, the defence secretary, and former transport secretary, said no decision has been taken yet but that its important to respond to the budgets. Every government has to look at the overall budgets and then make serious decisions, which go beyond the sort of back and forth in a studio like this. To say, is this affordable, under current circumstances . Im absolutely confident, for example, that when those statements were made, no one knew wed be in a War In Europe right now. 0k. With all of the consequences, all of the costs and all of the inflation. And any government that doesnt go back and then look at it is crazy. Labours been accused of sending mixed messages on hs2. We are supportive of h52 being built, but were responding to rumour and leak. And, look, victoria, this is a really important infrastructure project. What i say on your show matters, because we, the labour party, hope to be in government next year. Were not going to make decisions about National Infrastructure projects that involve tens of billions of pounds without all of the information being available. This weekend, Business Groups and political voices have been lobbying the government not to truncate hs2 further, with Pressure Mounting for decisions to be made. Noor nanji, bbc news. Live now to councillor bev craig, Labour Leader of Manchester City council and board member of the Northern Powerhouse partnership. Thank you forjoining us. Firstly your reaction to those comments from grant shapps. I your reaction to those comments from grant shawn your reaction to those comments from grant shanna grant shapps. I would say we are reaponding grant shapps. I would say we are reaponding as grant shapps. I would say we are responding. As the grant shapps. I would say we are responding. As the leader grant shapps. I would say we are responding. As the leader i grant shapps. I would say we are responding. As the leader i metl grant shapps. I would say we are i responding. As the leader i met the mare is the missing position, no one in government has a purchase as a cities to talk about it. Now of course, you would expect a government of the day to be looking closely to how they are spending the money. But what i would say is this once in a Generation Opportunity to invest in infrastructure to the north from the south for people travelling both ways for much needed capacity on our line is something that cannot simply be brushed aside. And of course money needs to be management this is a once in a Generation Opportunity to improve capacities of our railway. So i would urge the government strongly to firstly meet with us to tell us what they are thinking, but secondly not to make short term decisions that will have long term damage to our economy. That will have longterm damage to our economy our economy. How do people feel about hs2 our economy. How do people feel about hs2 in our economy. How do people feel about h52 in the our economy.

What people in manchester and across north regular the experience is railways that are outdated, Railway Stations built 200 years ago in the centre of manchester and it still stands there.

Apologies but i believe we just lost connection there. Lets go | just lost connection there. Lets go back to one of our stories looking at the asteroid that has landed in utah which is hoping to sell us a bit more about how life began here on planet earth. Lets cross now our science correspondent, Jonathan Amos is in utah for us. Describe to us the moments when they asteroid landed safely and scientists are now investigating in the work begins now. Yes scientists are now investigating in the work begins now. Scientists are now investigating in the work begins now. Yes it has been uuite an the work begins now. Yes it has been quite an amazing the work begins now. Yes it has been quite an amazing day, the work begins now. Yes it has been quite an amazing day, i the work begins now. Yes it has been quite an amazing day, i hope the work begins now. Yes it has been quite an amazing day, i hope you quite an amazing day, i hope you can hear me becausejust quite an amazing day, i hope you can hear me because just off to my right here the helicopters that went in and cover the capsule, arejust about to take off again. So they will be a little bit noisy for a while. But i will try and make out some of the scenes that we saw today. We saw this capsule come screaming into the atmosphere of planet earth moving at 12 km a second. Around 27,000 miles an hour. First of all he picked it up on these heat seeking cameras and then we got a view of a parachute. The Capsule Slung beneath it. Then it landed gently in the utah desert. It actually lent a little bit earlier than expected. We were expecting it to come down at 0855 local time, it came down it three minutes earlier. There will be something that the engineers at the capsule at Lockheed Martin but want to pour over, but i dont think the scientists care very much. They have the capsule back and they have got their sample back. Jonathan, we saw pictures earlier wrong of what they call the
