When you call someone or you call 911, you expect someone to show up. But dcs fire chief says his department is still struggling with response times to some of its most critical 911 calls in dc. Today the chief and the mayor laid out their plans to fix that. News4s Mark Segraves broke this story last night on twitter. Hes now live in northwest with the story youre seeing first on news4. Reporter yeah, good evening, wendy. Overall the numbers show us that when you call 911 for either fire or emergency, the response times actually have improved. But when you call for critical medical care like a cardiac arrest, thats where response times have not improved. To fix that today, the chief the mayor said one thing theyre considering is restricting who actually gets an ambulance when they call 911. We responded to over 200,000 emergencies last year. Reporter while dc fire did respond to over 200,000 calls last year, the chief says not all of those were true emergencies. Firefighters refer to dcs current policy as, you call, we haul. That means everyone who calls 911 for an ambulance gets a ride to the hospital whether they need to go or not. And that takes Critical Resources away from the more urgent calls for help. If the new recommendations are approved by the mayor, a nurse or a First Responder would decide whether or not to take the patient to the hospital. What were atalking about is make sure our personnel and hospital rooms are available for people who have having an emergency. Reporter today the chief and the mayor said theyre also considering hiring a private company to provided nurses screen some calls to determine if that ambulance is actually necessary before being dispatched. Chief dean has for months advocated placing a nurse inside the 911 call center, the departments new medical director is recommending a private firm. This nurse is able to further assess and direct a caller toward nonemergency department resources, including self care advice or nonemergency transport to primary care clinics or an urgent care center. Reporter and mayor bowser announced shes proposing new legislation that would require Insurance Companies to pay 100 of the cost of 911 transports to the hospital. This legislation will help close gaps in Insurance Coverage and ensure that more District Residents have access to emergency medical care. Reporter mayor bowser pointed out that are just recommendations. Shell decide between them. Coming up at 6 00, youll see what happened when a neighbor confronted her about what her insurance ideas would mean for his premiums if she passes that legislation.

The apollo 11 capsule which took americans to the moon and back will be leaving washington in october for a road trip. News4s Barbara Harrison is here with the story. Reporter you guys know ive been talking about nasa a lot lately, after having a chance to meet some of the folks down at nasa figures real life character helped in the mission to take americans to the moon and back. It was 1969 when that capsule carrying astronauts Neil Armstrong and buzz aldrin descended to the lunar surface in the module called the eagle. The command mod you wiule was t one to return to the earth. For the four decades that followed, its been on display at the smithsonian. In 2019, the country will celebrate the 50th anniversary of the moon landing. In advance of that, the capsule will be visiting houston, st. Louis, pittsburgh, and seattle. It will spend five months in each city. The Apollo Program in my view is one of the greatest amen when apollo 11 landed on the moon and humans first stepped on a celestial body, it changed the way we saw ourselves. Thanks to the smithsonian traveling service, for 65 years, our affiliate museums, 216 strong, were able to spread the wealth beyond the over 20 million americans and those from overseas who visit our institutions every year in washington and new york city. Reporter we all remember seeing it when it came back to earth and landed in the water. Catherine johnson was one of those who found out the trajectory that would bring it back so we could find it.

From nasa, its announced a major discovery that is literally out of this world. Seven rocky earthsize planets in a solar system about 40 lightyears away known as exoplanets, all seven orbit a single star thats smaller than our own. Scientists say their orbits are also smaller than in our solar system. They could potentially have water. Nasa hopes future telescope launches including one next year will help to study these exoplanets and analyze their surfaces. You may remember the acronym my very educated mother just served us nine pizzas. But then about a decade ago we dropped pizzas, or socalled dwarf planet could get a promotion. Some scientists wanted the International Astronomical union to dedefiredefine what constitu planet. Its supposed to be a round object in space smaller than smarts. The astronomers say classifying it as a planet is significant and encourages exploration. At the same time, the definition excepts our own moon and 110 other objects in our solar system could be reclassified as planets. Try making an acronym for that.
