Bad news: There is a small chance an asteroid will collide with Earth. The good news: Mankind has more than 115 years to prepare for it. According to a Washington Post report, NASA is preparing for possible tactics to deflect the asteroid Bennu, which will approach Earth Sept. 21, 2135. As of today, NASA rates Bennu's chance of striking Earth at one-in-2,700.The asteroid is roughly 1,600 feet in diameter, and would not be an Earth-ending event if it struck. But that doesn't mean it couldn't cause damage, especially if it struck near a populated area. Bennu is likely dozens of times larger than the object that struck near Chelyabinsk, Russia in 2013, causing hundreds of injuries, and thousands of broken windows. The event caused nearly million in damage to roughly 7,000 buildings. The 2013 event shows that even small objects are capable of causing massive damage. In 2016, NASA launched OSIRIS-REx, which will land on the asteroid and bring back samples. The information gathered could help NASA decide what steps it would take to deflect the asteroid. According to the Washington Post, NASA is working on a plan called the Hypervelocity Asteroid Mitigation Mission for Emergency Response, or HAMMER. NASA's HAMMER plan could involve using a nine-ton bulk impactor to push Bennu out of Earth's path. Another idea would be straight out of the movie "Armageddon," using a nuclear-type device to move the asteroid. A NASA engineer involved in the study told the Washington Post all of these ideas are theoretical. “We’re doing these design studies to prepare ourselves, so if we do find a threatening object, we’re better prepared to deal with it,” Brent W. Barbee, NASA engineer, told the Post.To read the Washington Post's full report, click here.  1855

As the nation debates on whether to reopen schools this fall, President Donald Trump said schools should “100%” be open this fall, despite concerns from educator unions and others over the spread of the coronavirus.During his coronavirus news conference on Wednesday, Trump was asked whether he planned on sending his son and grandchildren back to school this fall.“Yes, I am comfortable with that,” Trump said.“I would like to see the schools open. Open 100% and we will do it safely, we will do carefully but when you look at the statistics -- I just read having to do with children and safety ---- they are very impressive. They have very strong immune systems,” Trump added.Trump said that it is his belief that children are less likely to spread the virus. But research thus far has not been conclusive to back Trump’s claims.A study released from South Korea and published by the CDC found that while children under age 9 were less likely to spread the virus, youth ages 10 through 19 were just as likely as adults of spreading the virus.The study also found that closing schools in several Chinese cities, including Wuhan, showed that school closure and social distancing significantly reduced the rate of COVID-19 among contacts of school-aged children. “The role of household transmission of SARS-CoV-2 amid reopening of schools and loosening of social distancing underscores the need for a time-sensitive epidemiologic study to guide public health policy,” the researchers wrote.The American Federation of Teachers this week pointed toward a three-point plan that the US should implement for reopening schools.“Our plan details three conditions essential for schools to reopen,” wrote Randi Weingarten, president of the American Federation of Teachers. “First, the average daily community infection rate among those tested for the coronavirus must be very low. (New York Gov. Andrew Cuomo has required the rate not to exceed 5 percent for at least 14 days.) Second, schools must employ public health protocols, including 6-feet social distancing, masks, deep cleaning and handwashing stations. Third, adequate resources must be available to enact these safeguards, including funding for additional nurses, guidance counselors and teachers to reduce class size.”Weingarten said that Trump has politicized reopening schools, and she called on Congress to approve giving schools additional funding to reopen. Weingarten projects that it would take 6 billion nationwide to provide essential services for schools."Expenses have increased because of the fight against coronavirus," she said. "They not only need funds to provide essential services, the average school will need an additional .2 million, or ,300 per student, to open its doors safely." 2770

ATLANTA (AP) — A representative for Tyler Perry says the filmmaker and actor offered to pay the funeral expenses for an 8-year-old girl who was fatally shot in Atlanta. Secoriea Turner was shot while riding in a Jeep Cherokee with her mother and another adult on Saturday night. The shooting occurred near a fast-food restaurant where a Black man, Rayshard Brooks, was killed by a white police officer on June 12. The Wendy's restaurant was later burned, and the area has seen frequent demonstrations against police brutality since. Perry paid for Brooks' funeral last month. No suspect has been arrested in the girl's shooting death. 642

  

AUSTIN, Texas. (KGTV) -- A series of explosions in Austin has terrified residents as hundreds of local and federal officials try and determine who is behind the incidents. The first explosion was set off on March 2 and killed 39-year-old Anthony Stephan House. Numerous other people have been killed or injured by the series of bombings including 17-year-old Draylen Mason, who was killed after a package bomb went off inside his home on March 12. Mason's mother was also injured in the explosion. A 75-year-old woman, 22-year-old man and a 23-year-old man were also all injured in the serial bombings. The six bombings left police in Austin warning residents to not take any chances, saying if it looks suspicious, don't approach it. The timeline below shows all six of the bombings federal officials believe are tied together:  887

  

As the opioid crisis continues to damage communities across the country, new mapping technology is helping family members of victims cope by allowing them to crowdsource an interactive memorial.The "Celebrating Lost Loved Ones" map, created a couple of months ago, now marks the lives of thousands people lost to opioids. The map was created by engineer Jeremiah Lindemann and allows users to add photos and short stories of loved ones who have passed away, including the place of their passing.The goal of the map is to create a place to honor and respect overdose victims across the United States."(We want a map) that emphasizes the human toll behind the opioid crisis with a visual record of the victims it is leaving behind," Lindemann said. 764
