Amazing mystery. And we have liftoff the first stage was seconds into a fourminute burn when the antares rocket stalled, fell backward and exploded. Nearly threequarters of a Million Pounds of thrust went haywire and spectators across the bay say the blast shook the ground even there. We felt the concussion, it was a huge blast. It hit us, it sounded like a sonic boom. It also clearly shook virginiabased Orbital Sciences, the private contract that are built the rocket under a 2 billion contract with nasa now needs answers. The investigation will include evaluating the debris that we will find around the launch pad. If you find anything that washes ashore in the local area or came down in on your farm, definitely do not touch it. No one was hurt in the explosion, but gone in a flash 1600 pounds of science experiments on everything from meteors to human blood flow. More than 1600 pounds of hardware, computers, space walk equipment and 1400 pounds of food for the iss crew. That does not create an instant emergency, but it will put extra pressure on Upcoming Missions to reestablish the supply chain to those astronauts in orbit. And the explosion could create political pressure in the continuing debate over how much space travel can or should be put into the hands of private companies. It is worth noting that a Russian Rocket took off this very morning with more supplies. For the iss and theres another launch here by a private company, spacex should be taking off on december 9th also to rendezvous with the iss. Tom, thanks so much. One of the big concerns is would the people in the space station be okay. We believe all the sources say the same thing yes, they should be. It is also a big vote for unmanned missions, that would have been a big part of the controversy as well. God forbid there had been some people in this rocket. Why did it happen and how did happen . We know more than were reporting so far. Were going to talk with cnn space analyst miles obrien coming up about what we actually understand about this and what it may mean for the future of privatized Space Missions. And a developing story about potential terror attacks on u. S. Soil. It turns out the feds are ramping up security on thousands of government buildings. The question is why. We know the action is coming after the shooting spree in ottawa last week. You remember that where this deranged gunman opened fire and killed a soldier and stormed into the Parliament Building before he was shot dead by the very brave sergeant at arms there. Now Homeland Security secretary jeh johnson is calling the enhanced security a precautionary measure following ongoing terror threats. Lets get the latest from cnns justice correspondent pamela brown live from washington. The obvious confusion is do you have new information fueling these threats . Is it just precautionary . Why is it targeted to one part of the Security Agency . Curious stuff. Thats the big question. We are told by an official that this is not in response to any new intelligence indicating additional threats to the homeland. But that department of Homeland Security secretary jeh johnson is stepping up security at the government buildings in d. C. And other cities after a series of events that have u. S. Authorities on high alert. This morning, concerns about terror attacks on the homeland continue. The u. S. Now beefing up federal security in more than 9500 government buildings and washington, d. C. And across the country. These photos taken late tuesday reveal a much high her Police Presence near the white house. The department of Homeland Security jeh johnson says the new security measures are a precautionary step against terrorist organizations. Its simply being safe rather than sorry. This move comes in response to continued calls for attacks against government officials on u. S. Soil. From groups like isis. There was a specific request made about a month ago, by isis, theyre looking now at lone wolves to attack instruments of, that represent western governments basically. This, as the al qaeda offshot, corazon that the most recent terror attacks across the u. S. Border. Last wednesday, a 32yearold muslim convert who Officials Say had connections with other extremists killed a canadian soldier, then opened fire inside canadas parliament. And two days before that, canadian Authorities Say a radicalized islamist struck and killed a canadian soldier with his car. The federal facilities at risk see some 1. 4 million visitors daily. Officials not disclosing those locations. And johnson says state and local governments need to be equally vigilant, particularly in guarding against smallscale attacks by lone offenders and urges the public to be on the lookout. Bottom line, alisyn, officials dont want to take chances, so thats why theyre stepping up security. Thanks so much for all of that background. Lets bring in tom fuentes, a cnn Law Enforcement analyst and former fbi assistant director in washington. Good morning. So is all of this a response to what happened in parliament in ottawa . I think it must be, alisyn, because its so nonspecific. When youre talking 10,000 buildings across the country, to me, where does this end . You put more security guards in front of the buildings, well its those very guards that are the targets. So if we want to make more targets available for isis to shoot at, thats one way to do it. I dont know how you call this off. Weve had these threats that isis has put out on the internet. Asking for people to attack soldiers or police or the government or anybody else. And i just think you know at some point, its going to be difficult to stop it. In either event whether you have 10,000 additional buildings enhanced or not. So, it sounds like youre not a fan of this concept. But cant you just look at whats been happening here at home. Two fencejumpers have made it over the fence at the white house, one of them into the white house. Isnt it time for security tuneup here . Well you can tune it up. But if you look around, you know how, i walk around Downtown Washington all the time and the buildings are right up to the sidewalk, most of them. Busy streets where people can do like what happened in oklahoma city. You know, use a truck bomb. Drive up on the sidewalks, people are eating lunch and having coffee at sidewalk cafes, theyre vulnerable. Pedestrians at crossing walks, all the federal buildings. And this is washington, a prime target for isis or anybody else that wants to make a terrorist statement. But when you talk 10,000 buildings across the country, which buildings and what type of security . And on the other side, when do you call it off . Once you dial these threats up, and enhance the security, you know its kind of lime the embassy closings a year or so ago when you close 25 embassies, when do you decide not to close them when its not a specific threat. When it is a specific threat, theyll eliminate it and theyll go after that group and they will do the investigation thats necessary to disrupt and dismantle a specific organization doing a specific threat. But to be just generally on guard because somebody, some deranged person in his head will take an isis order and carry it out it just seems to be in a way mission impossible. Well heres what Homeland Security secretary jeh johnson says is the reason for this, beyond what happened in canada. He said the reason for this action are selfevident. The continued public calls by terrorist organizations for attacks on the homeland, including against Law Enforcement and other government officials. Thats the reason that hes giving. But tom, i hear what youre saying, youre saying its an exercise in futility. So what is the answer . I think the answer is what it has been, is to try to defeat the ideology and the long run. And were not making really efforts at that. If we catch these terrorists, we catch people trying to join isis and fly out of the United States, we lock them up, and thats fine. Except then theyre in prison, able to recruit more converts. And increase that effort. And i think that you know, right now, what were trying to do is really, you know trying to work on the symptom. Its stead of the cause. Until we really defeat the ideology and defeat the recruiting ability of isis, you know were really not going to be successful at this. And this will go on for decades. Of course, it is much harder to defeat the ideology than it is to add some Security Officers to various federal buildings so it sounds like we will be seeing the latter happen in the next few weeks. Tom fuentes, thanks so much, great to get your perspective. To that point of whats happening on the ground, the question is has there been a turn in the battle against isis . Kobani, once an afterthought is now seemingly the key battleground and there was a surprise this morning in the form of reinforcements for kurdish fighters besieged by isis. More reinforcements are coming today. The surprise is who came first. And why. Lets get to Senior International correspondent Nick Paton Walsh joining us from the syrian Turkish Border. Nick, what do we know . Very volatile morning, weve seen the second large second air strikes since we arrived here this morning to go in a lot of gunfire. The syrian furds fighting for that city, expecting to see iraqi peshmerga flying in separately. Them to arrive at dawn. But they got a surprise instead, they got more syrian rebel fighters coming in. Potentially over 50, maybe as many as 200 according to their commander. Thats turkeys idea to send in syrian rebel enforcements into syria here. The fighting was intense since they moved in at about 5 30 this morning and yet more will still come, too, and then theres the peshmerga as well. Their convoy expected in the hours ahead. Some of them already. We understand very close to the border. Theyre waiting for their motorized component to join up with them. They then will go through the official Turkish Border crossing behind me. Quite close to where that plume from the air strike is at the moment. A lot of fighting happening right now. I think morale is high, you heard the kurds just behind me playing loud music behind me in the last few minutes. Things are which changing fast of the reinforcements are on the way. The real question is, what is isis role in this . Whats their role . They can still fight back. Well have to see how the reinforcements come in and how the state of play changes on the ground. Stay safe and keep us informed. Lets get to michaela for more. Developing overnight, a potentially Devastating Oil spill sm in sweden. A large ship hauling 52 tons of oil has run aground in stockholms scenic archipelago and its spilling oil into the baltic sea.

The white house shut down its Computer Network after it discovered suspicious cyberactivity. Now officials arent saying what exactly happened. But they are not calling this a hack.

Is he in or is he out . Good morning, michaela. Well Ferguson Police chief tom jackson is expected to step down as part of a plan to reform the Police Department there. Now this is as part of a plan being discussed by local, state and federal officials, we expect an announcement could come as soon as next week.

Louis county grand jury on whether to bring charges against darren wilson, the officer who shot Michael Brown. Now the plan is for the st.

One into the shooting itself and one into the Ferguson Police departments practices. A lot of questions swirling. Is this going to happen, what will it mean for ferguson. And the conversation going on. Evan thats it, we shall see, thanks so much. An update for you now on a story we brought you yesterday.

Theyre now going to have to evacuate a town this is molten rock, we have no way to stop it. These people are all helpless to what the natural course of events are here. So right now we have cnns martin savidge, who is following this situation. But literally, people are just watching and waiting right now. Heres what we know so far. This has been a slowmotion disaster, officials have actually had months to prepare for it. But they admit now that its here, its a whole different emotional chapter. The day residents have been fearing is finally here. The town of pahoa is burning. A 2,000degree river of molten lava thats been approaching for months is now searing the town and its just the beginning. Overnight, the First Official evacuation notices went out. Face to face, knock on the door, by a Public Safety official. The lava is moving at about 30 feet an hour. And at its current speed, it will cut the towns main street in less than two days. In a helicopter, i could follow the trail of destruction from the slopes of the kilauea volcano to the edge of town. Thats the lava field and most of the lava is moving underground. Can you see how it transforms the landscape it wipes out the vegetation. The lava invaded a local cemetery, surrounding the while tombstones. Theres nothing that can be done. In other words if youre thinking why dont they divert it or try to dig a channel to go around the town . Hawaii has tried that in the past. Its never been effective. On the ground, crews race to construct new roads around the lava. To keep an Evacuation Route open and businesses connected to the nearby city of hilo. Hopefully well be able to always stay open. Hopefully pahoa will still be viable. Even as the danger creeps ever closer. Some residents say they will stay. If only to watch their homes burn. When the lava flows come through their subd
