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 debate over voting by mail continues, President Donald Trump told a North Carolina news outlet that voters should test election safeguards by voting both in person and via mail, something which could cause voters legal issues.Trump has expressed doubt in mail-in voting during the 2020 election cycle, claiming that mail-in voting is prone to fraud. But many states, some of which are led by Republicans, are ramping up mail-in voting efforts. Proponents of mail-in voting say that it is a safer alternative than in-person voting given the coronavirus pandemic.The president, speaking to a reporter from WECT, said he wanted voters to test the state’s safeguards.“So let them send it in and let them go vote, and if their system’s as good as they say it is, then obviously they won’t be able to vote,” Trump told WECT. “If it isn’t tabulated, they’ll be able to vote. So that’s the way it is. And that’s what they should do.”In North Carolina, it is a Class I felony to vote twice. The National Conference of State Legislatures has a list of laws pertaining to “double voting” on its website. Voting twice in an election is illegal across the US.Meanwhile on Wednesday, US Attorney General William Barr said that voting by mail is “playing with fire.”“We're a very closely divided country here,” Barr told CNN’s Wolf Blitzer. “And if people have to have confidence in the results of the election and the legitimacy of the government and people trying to change the rules to this, to this methodology, which as a matter of logic is very open to fraud and coercion, is reckless and dangerous. And the people are playing with fire."While there is scant evidence of widespread voting fraud in past elections, there are questions on the US Postal Service’s ability to return ballots in time to be tabulated.In Florida, Volusia County Elections said more than 1,000 ballots that should have been counted for last month’s primary did not arrive on time. There were 1,281 ballots postmarked the day before Election Day, but election officials received them too late to be counted.The USPS has experienced some service disruptions as some sorting machines have been removed from some post offices. While this had an impact on last month’s primary, the USPS slowdown has also caused slowdowns for essential items such as medicines and paychecks. 2350

AUSTIN, Texas (AP) — Texas and six other states are suing to end once and for all a program that would protect some young immigrants from deportation.The lawsuit announced Tuesday comes a week after a federal judge in Washington ordered the Trump administration to resume the Deferred Action for Childhood Arrivals program.Immigrants under the Obama-era program are commonly referred to as "Dreamers." Republican Texas Attorney General Ken Paxton had threatened legal action for the past year if the program didn't come to a halt.Joining Texas in the lawsuit are Alabama, Arkansas, Louisiana, Nebraska, South Carolina and West Virginia.A federal judge in Washington called the Department of Homeland Security's rationale against the program "arbitrary and capricious." He gave the Trump administration 90 days to make a new case. 837
