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

ATLANTA — Atlanta's police department said Thursday that it can still police the city even if officers are calling in sick to protest efforts to impose reforms.A department tweet urged people to continue calling 911 if they have an emergency.Mayor Keisha Lance Bottoms also insisted that the police department would be able to operate effectively despite the reaction of some officers to her calls for reforms and the charges against two officers in the shooting of Rayshard Brooks in a Wendy's parking lot.On Wednesday evening, hours after Officer Devin Brosnan and former Officer Garrett Rolfe were formally charged in connection with Brooks' death, reports surfaced that a large number of Atlanta police officers were calling in sick in protest. 756

At a press briefing in Washington on Friday, Vice President Mike Pence said the White House coronavirus task force had identified 16 states — about one-third of all states in the nation — where COVID-19 cases are on the rise.According to Pence, in the other 34 states, there is a "measure of "stability" among cases — saying that while these states may experience new cases, "positivity rates are stable."Pence said that most of the states with rising cases are in the "Sun Belt." He said that he and other health officials would travel to Arizona, Florida and Texas — three states experiencing severe spikes in cases — next week, to meet with governors.The task force reported that a majority of new cases have been reported in people younger than 34 — a development that Pence called "encouraging" in some ways because young people are more likely to recover from the virus.According to Pence, there have been 2.5 million confirmed cases of the virus in the U.S. According to Johns Hopkins, there are about 4,425,000 confirmed cases of the virus.During Friday's briefing, Dr. Anthony Fauci — America's top expert on infectious diseases — said that some areas of the country as facing a "serious problem" amid rising numbers. He added that Americans have a "societal responsibility" to continue social distancing, adding that those who leave their home for crowded places become part of an infectious chain."Ultimately, you will infect someone who is vulnerable," Fauci said.The task force and President Donald Trump held near-daily briefings throughout March and April. But the nation's top health experts have rarely appeared on-camera in recent weeks as the administration has focused on re-starting the economy.The briefing comes a day after Johns Hopkins reported 40,000 new cases of the novel coronavirus, the highest single-day increase since the pandemic began. President Donald Trump has maintained that the increase in cases is the result of increased testing capacity, but the CDC reports hospitalizations linked to the virus are also on the rise.It also comes following a week of confusing messaging regarding the administration's policy on testing. On Saturday at a rally in Oklahoma, Trump told supporters that he asked that testing be "slowed down" to deflate new case numbers artificially. On Monday, press secretary Kayleigh McEnany said Trump made those comments "in jest," but Trump quickly contradicted her, saying he "doesn't kid." Dr. Anthony Fauci, the nation's top infectious disease expert, later testified at a House committee hearing that he had not been told by anyone in the administration to slow down testing, and that increasing testing capacity remains the goal of the task force.Several states that were quick to lift lockdown restrictions are now moving to re-impose social distancing measures. On Friday, Texas ordered the closure of bars and re-imposed limits on in-restaurant dining. Also on Friday, Florida ordered that bars can no longer serve alcohol on-site as cases continue to spike. 3036

AVILA BEACH, Calif. — Officials say two women are lucky to be alive after a humpback whale capsized their kayak as they paddled in the ocean on Monday.The incident, which occurred near the Cal Poly Pier, was caught on video by multiple people in the area.Julie McSorley says she went out Sunday and took pictures of the whales and convinced her friend to go kayaking with her on Monday.McSorley says there were a lot of birds and fish in the area, so people had their phones at the ready. She said she and her friend could see whales off in the distance.Seconds later, one of the whales was right underneath them.While some video footage makes it appear as the women went inside the whale's mouth, McSorley says their kayak just overturned, and they were thrown underwater.Video shows McSorley screamed before going underwater for about five or six seconds.Humpback whales are considered an endangered species, and marine mammal experts say they can be unpredictable and dangerous. Experts say people should keep about a football field's worth of space between themselves and the large mammals, when possible.The Port San Luis Harbor Patrol says enforcement can be difficult. Boaters can think they've left a whale plenty of space, but the mammals move quickly.The whales have been making appearances close to shore between Morro Bay and Avila Beach in recent days. Marine mammal experts say they are looking for food that is currently easy to find near the shore.This story was originally published by KSBY in San Luis Obispo, California. 1548

Attorneys general from several states plan to jointly file new antitrust litigation against Facebook in the coming days, according to reports from CNBC and the Wall Street Journal.According to CNBC, as many as 40 states are expected to join New York in suing the social media giant. The report also says that the Federal Trade Commission could file a separate but related complaint in district court.While the specifics of the pending lawsuit are unclear, Facebook has been criticized for swallowing up competitors, like Instagram and WhatsApp for fairly reasonable prices.The pending lawsuit would mark the second significant piece of legislation filed against a Silicon Valley giant in recent months. In October, the Justice Department sued Alphabet, the parent company of Google, and alleged the company is a search engine monopoly. 843
