NASHVILLE, Tenn. — Metro Police have identified the six officers who first responded to the scene of the downtown explosion Christmas morning. City officials say these officers showed up to a "shots fired" call on 2nd Avenue around 5:30 a.m. Upon arrival, an RV on the street played a recording and countdown, saying the vehicle contained a bomb and warning everyone to leave the area. The officers helped several people evacuate before the RV exploded shortly after, around 6:30 a.m."They immediately began knocking on doors, not knowing when the bomb would go off," Chief John Drake said at a press conference Saturday night. "They didn't think of themselves...they thought of the citizens of Nashville. They saved lives today, and their heroism should be noted." Officer Brenna HoseyOfficer James LuellenOfficer Michael SiposOfficer Amanda ToppingOfficer James WellsSergeant Timothy MillerMayor John Cooper commended the officers as well. "They took swift action, directed people away, even when their own lives were in peril. This is a year we understand what first responders mean to our community time and time again." 1132

NASA's OSIRIS-REx mission and the asteroid Bennu have had a date planned for two years, and just after noon ET today, they finally got to meet face to face. OSIRIS-REx fired its thrusters for a small burn, putting it about 4.3 miles from Bennu, marking the end of its journey to the asteroid.The mission -- which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer -- is NASA's first asteroid sample return mission. It launched in September 2016 and will spend two years up close and personal with Bennu. First images of the asteroid from the spacecraft's perspective have appeared as it got closer and closer.On Tuesday, the spacecraft will fly within 5 miles of Bennu, which will help design future orbits and map the surface.Over the next year, OSIRIS-REx will survey the asteroid using five scientific instruments on board the spacecraft. These instruments will help it determine a safe location from which to collect a small sample from Bennu's surface that will be returned to Earth in September 2023."Bennu's low gravity provides a unique challenge for the mission," said Rich Burns, OSIRIS-REx project manager at NASA's Goddard Space Flight Center. "At roughly 0.3 mile in diameter, Bennu will be the smallest object that any spacecraft has ever orbited."The sample from Bennu, a near-Earth asteroid, could help scientists understand not only more about asteroids that could impact Earth but about how planets formed and life began.OSIRIS-REx has a camera suite, a laser altimeter for 3D mapping, a thermal emission spectrometer to take temperature and mineral content and spectrometers to measure X-rays, nearly infrared and visible light.An arm mechanism called TAGSAM will reach out to collect the sample from Bennu's surface, making contact with the asteroid for five seconds in July 2020. During this contact, the arm will use a nitrogen gas burst to stir up rock and other materials on the surface so it can capture them. There is enough nitrogen for three attempts if the first is unsuccessful.NASA said the estimated 2.1-ounce sample size equates to about 30 sugar packets worth of dirt and rocks.The arm has a full range of motion, with joints capable of movement comparable to shoulder, elbow and wrist joints. It was "flexed" in space for the first time on November 14."The TAGSAM exercise is an important milestone, as the prime objective of the OSIRIS-REx mission is to return a sample of Bennu to Earth," said Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, Tucson. "This successful test shows that, when the time comes, TAGSAM is ready to reach out and tag the asteroid."In 2021, it will be time for the spacecraft to essentially turn around and begin its two-year journey home. The sample will be packed into a capsule that will drop in the Utah desert in 2023.For two years after the return, the sample will be cataloged and analyzed. Afterward, 75% of the returned sample will remain at NASA's Johnson Space Flight Center so it can be used for more research by scientists from around the world.Why did NASA select Bennu out of the 780,000 known asteroids in our solar system?It was discovered in 1999, and scientists have been studying it ever since. The asteroid fits a number of criteria that make it intriguing and convenient.Bennu is relatively close to Earth, and its orbit even crosses that of our planet, making a close approach every six years. Though small asteroids can rotate very quickly, Bennu has a diameter just a bit bigger than the height of the Empire State Building and rotates relatively slowly, each 4.3 hours. This means OSIRIS-REx can match its velocity and touch down briefly.The asteroid could pass close to Earth, closer than the moon, in 2135, with even closer approaches possible in 2175 and 2195. A direct hit is unlikely, but the data gathered during this mission can help determine the best ways to deflect near-Earth asteroids.The asteroid is also old and well-preserved, full of valuable materials that may even contain clues about how life began. Bennu is essentially a leftover from the formation of our solar system billions of years ago, although some of the minerals inside it could be even older.This carbon-rich asteroid could be full of organic molecules, metals, platinum and even water -- the essential ingredients for life. It's because of objects like Bennu that these resources were delivered to Earth during its formation.Asteroids could even serve as fuel stations for robotic and human missions if we can unlock the hydrogen and oxygen inside them, NASA said.Bennu probably broke off of a larger asteroid in the asteroid belt between Mars and Jupiter a couple billion years ago. This knocked it through space until an orbit close to Earth locked it in place. And Bennu is believed to be a grouping of rocks held together by gravity rather than a single object.But its orbit drifts 0.18 miles each year toward the sun, and OSIRIS-REx will enable researchers to understand why and to predict Bennu's movements. This could also explain how it ended up as a near-Earth asteroid."The story of this asteroid is the story of the solar system," said Bashar Rizk, instrument scientist for OSIRIS-REx. "When we understand Bennu, we will understand something fundamental about our solar system."The-CNN-Wire 5356

NASHVILLE, Tenn. - Every week, hundreds of people from around the world visit The Free Pizza Dude account on Imgur, created by a Nashville man, to either ask for food assistance or help out."I've been able to carve out this kind of wholesome side of Imgur where people come to my post to help other people," said Mr. Puckett, the virtual Imgur user with more than 7 million up-votes. "We had all of these people kind of wanting to help, but had no idea how to."In August 2019, Mr. Puckett created The Free Pizza Dude page to help connect the people in need of a meal to willing donors."We're not trying to end world hunger we're trying to make people happy. [Those] who would not otherwise be able to afford this kind of food," said Mr. Puckett.So far, the page has allowed people to send nearly 4,000 pizzas to strangers in need.Mr. Puckett knows what it is like to be hungry."I had problems with alcohol and was homeless for four years before I got on Imgur. I knew if I ever got on my feet again, I wanted to do something where we could send food to people that wasn't rice and beans - that wasn't food shelf kind of food - something they could really enjoy and remember for some time because I always did and I always remembered the food people sent me," he said.Through his website, pizza angels from all over the world have sent paid-for pizzas to strangers and fulfilled more than 100 detailed grocery requests too."Everybody wants to help, but they want to have fun doing it, and they want to have security that they're helping the right person, and I think we've done all three of those things," he said.Mr. Puckett puts out a new call for pizza donations every Friday.He said the reason he does this is simple."I was homeless for so long and so many people from my childhood days helped me. I needed help from every person in my life for so many years so once I finally got stable, and got an apartment and home I knew I had to be that person," he said.Nashville Mayor John Cooper recently named Mr. Puckett a Community Hero of the Week.This story was first reported by Hannah McDonald at WTVF in Nashville, Tennessee. 2136

NASHVILLE, Tennessee — After Edmund Zagorski was electrocuted by the state this week as it carried out his death sentence, could we see more electric chair executions in Tennessee going forward?One Nashville attorney who helped craft the state's death penalty laws says yes.Nashville Attorney David Raybin says he thinks more inmates who committed their crimes prior to 1999 may shy away from lethal injection, given the debate over whether the chemicals used in lethal injection may torture inmates to death."In the future, I think more inmates who are eligible for the electric chair will elect to use it," Raybin said.Raybin says he understands that emotion from people who think that convicted murderers should suffer... but he says that would make the state no better than the criminals. 810
