At age 106, Sen. John McCain's Roberta McCain mother will be in attendance at the late senator's funeral this Saturday in Washington, D.C., and his burial service in Maryland, the Associated Press reported. Roberta McCain has outlived the son she called "Johnny," as the U.S. Senator from Arizona died on Saturday at the age of 81. Sen. McCain will be lain in state at the U.S. Capitol on Friday before his final services on Saturday. Roberta McCain, at age 96, was active on the campaign trail for her son during his presidential bid. She also made a number of appearances on television, including one controversial spot on MSNBC's Hardball, where she went after fellow GOP presidential hopeful Mitt Romney. Roberta McCain had an identical twin sister, Rowena Wright, who died at the age of 99 in 2011.  842

Attorneys for the family of Breonna Taylor have agreed to a million wrongful death settlement with the city of Louisville, Kentucky, officials said in a press conference Tuesday.According to Ben Crump, an attorney for the family of Breonna Taylor, the settlement was the largest sum paid out to the family of a Black woman killed during an interaction with a police officer.In the settlement, the Louisville Metro Police Department also agreed to make several policy changes. Those policy changes include:Requiring a commanding officer to approve search warrants before a judge approves them.Implementing an "early warning" system to detect unnecessary use of force among officers.Operational changes regarding officers placed on leave.Implementing a program that offers housing credits to police officers to encourage them to live in the city limits.Offering officers an extra two hours of paid time for community engagement.Expanded drug and alcohol testing within the department.Louisville Mayor Greg Fischer said later that the city did not admit any wrongdoing as part of the settlement.Attorneys for Palmer's family thanked Fischer for his administration's work in reaching a settlement. But they also called on state officials to press ahead with charges against the police officers involved in the March 13 shooting that left her dead."It's time to move forward with the criminal charges," said Tamika Palmer, Breonna Taylor's mother.Ben Crump, an attorney representing Taylor's family and the families of victims several other high-profile police shootings, also called on Kentucky Attorney General Daniel Cameron to charge the officers involved, saying the officers should be charged "immediately, this week."Thursday's presser closed with some in attendance shouting chants of "say her name" and "arrest the cops."The settlement is the result of a wrongful death lawsuit filed by Taylor's family. Breonna Taylor was shot and killed when plain-clothes narcotics detectives entered her apartment to serve a warrant.Taylor's boyfriend, Kenneth Walker, says he fired a "warning shot" at the officers, thinking they were intruders. Officers then responded by firing dozens of bullets, leaving Taylor dead.Walker was later arrested and charged after an officer was injured in the shooting. Charges against Walker were eventually dropped.Walker has maintained that while police did knock on the door prior to entering, officers did not identify themselves before attempting to enter Taylor's apartment. Some neighbors have also said that they did not hear police announce themselves before entering the residence.Taylor's death has already prompted a ban on "no-knock warrants" in Louisville. Sen. Rand Paul, R-Kentucky, has also introduced a bill that would ban such warrants nationally.Taylor's death has been a flashpoint for protesters calling for an end of police brutality and systemic racism. Athletes and entertainers have publicly called for the arrest of the officers who were involved in the raid on Taylor's apartment.One officer involved in the shooting, Det. Brett Hankinson, has been fired from the department. None of the officers have been charged with a crime. 3194

AUSTIN, Texas – More people have now voted early in Texas for Tuesday’s general election than voted in total in the state during the 2016 election.As of Thursday, data on the secretary of state’s website shows a total of 9,009,850 Texans had voted either by mail or in person, and there’s still one more day of early voting in the state.That number surpasses the record-breaking 8,969,226 votes that were cast in the state during the 2016 election.The high voting turnout signals that Texas may be a true battleground state in the 2020 election.Democrats are trying to take advantage of the enthusiasm to flip the traditionally Republican state and collect its 38 electoral votes. Though, pollsters at FiveThirtyEight show President Donald Trump is still “slightly” favored to win the state, with a 66% chance. That’s according to the website’s forecast, which is based on polling averages.Still, Joe Biden's campaign appears to see potential in Texas and is even sending running mate Kamala Harris to the state Friday to campaign in the final leg of the presidential race. 1081

  

As people prepare to travel for Christmas, experts are concerned about another spike in coronavirus cases.We are almost a month out from Thanksgiving, and according to the COVID Tracking Project, more than 47,000 people in the U.S. have died from COVID-19 since Thanksgiving.And although the CDC advised against traveling, the Transportation Security Administration screened 9.5 million travelers during the 10-day Thanksgiving travel period.TSA also screened more than 3.2 million people at airports nationwide this past weekend.And as people gear up to spend the Christmas holiday with loved ones, the surge of new COVID-19 cases continues with no end in sight.The Harvard Global Health Institute and Brown School of Public Health created a risk-assessment tool that color-codes states with over 25 new daily cases per 100,000 people. The color red on the map means the state is considered "at a tipping point."According to the Harvard and Brown researchers, the 10 worst states considered to be "at a tipping point" are Tennessee, Rhode Island, California, Alabama, Arizona, Oklahoma, Indiana, Utah, Arkansas, and Delaware.According to Johns Hopkins University data, in Tennessee, the state's positive rate is 19.2%.In Alabama, the state's positive rate is 40.4%. Arkansas's positive rate is 18.7%, Arizona's is 13.1%, Delaware's is 7.7%, 13.3% of COVID tests in California are positive, Oklahoma's positive rate is 21.1%, Indiana has an 11.6% positive rate, Rhode Island is at a 6.3%, and 17.6% of COVID tests in Utah are positive.According to the CDC, between 1.2 million to 2.3 million new cases are likely to be reported in the week ending January 9, 2021. 1671

  

At 3 p.m. ET on Monday, November 26, a group of researchers will be really sweating. The NASA InSight spacecraft will try to land on Mars.After six months of flight, the lander component of the probe will detach itself from the cruise stage and head into the atmosphere. The lander component initially looks a fair bit like the re-entry capsule used in the 1960s and 1970s for the Apollo moon missions -- sort of conical, with a smooth and flat bottom. That bottom is a crucial heat shield that is designed to protect the probe as it passes through the thin Martian atmosphere.The landing is a devilishly difficult feat. The landing capsule has to batter its way through the atmosphere. It will fly through the Martian air at an initial speed of 12,300 mph, and it must hit the atmosphere at an angle of precisely 12 degrees. Any shallower, and the probe will bounce off into deep space. Any steeper, and the probe will burn itself up in a spectacular and fiery death. The probe will first touch the atmosphere six minutes and 45 seconds before landing. During this phase, it will experience acceleration 12 times that of the Earth's gravity. Were the probe a 150-pound human, during the flaming descent, it would weigh nearly a ton.About 3? minutes after the probe hits the atmosphere, a parachute will deploy, slowing down the probe even more. Fifteen seconds later, explosives will blow the heat shield off, exposing the actual InSight probe hidden inside. Ten seconds after the heat shield falls away, the probe will extend its legs, much like an airplane extends its wheels before touching down.The probe will fall for an additional two minutes attached to the parachute and protected by its conical shell. About 45 seconds before InSight lands, it will drop out of the shell and fall toward the surface. As soon as it leaves the shell, its landing rockets will ignite.The actual InSight probe looks a little bit like the Apollo moon lander, with three legs to support it and a boxy top. The rockets will slow it further and stop any remaining horizontal motion. Then, about 15 seconds before touchdown, the InSight probe will descend at a speed of 8 feet per second, before hopefully touching down gently on the Martian surface.The entire landing sequence will take about seven minutes to occur. A radio signal from Mars to Earth currently takes about eight minutes and seven seconds to get here. So the complete landing process will take place before we find out if it was successful. It will be done automatically, entirely by the probe itself. For the scientists and engineers who designed InSight, this is called "seven minutes of terror."And they are right to be worried. Mars is a graveyard of failed probes. There have been 44 attempts by various national space agencies to land on Mars. Eighteen have been successful. Twenty-three have not. Three have achieved orbit but failed at a landing.So, what does InSight hope to achieve? Well, as it happens, a lot. But it's different than the intrepid Curiosity probe, which NASA landed in 2012. InSight will not move around. Instead, it will stay put and tell us of the interior of Mars.One thing it will do is emit radio waves that we can monitor on Earth. By making careful measurements of how the frequency of the radio waves change, we will be able to measure the degree to which Mars wobbles as it rotates. That will tell us something about the core of the planet, specifically its makeup and information on the degree to which it is molten.InSight will also deploy a seismometer to listen for marsquakes (like earthquakes, but Martian-style) and for impacts of meteors on the planet. Information gleaned from the waves the seismometer detects will tell us more about the planet's interior.The third thing InSight will do is to dig below the planet's surface. Using a jackhammer, the probe will drill down 5 meters (16 feet) into the planet and, basically, it will take the planet's temperature.There are many reasons this is interesting. Taking the temperature at that depth will allow planetary scientists to determine how much heat is escaping from Mars. More broadly, this measurement will allow a clear determination of the temperature of the planet much closer to the core.This information will tell us a lot about how Mars formed, which, in turn, will add to the information of how rocky planets, including our own Earth, typically develop.And if you're more of an explorer kind of person and not so interested in Martian geology, it will also tell us how warm the planet is at modest depths, which will tell us if there is any chance of liquid water on the planet. Perhaps obviously, if the Martian subsurface is warm enough, any buried water will be in liquid form and not ice. Finding liquid water would be the key discovery that would make Martian exploration relatively easy. A relatively recent possible discovery of a buried Martian lake was promising, but the data was not conclusive. Knowing that the ground is warm would be very comforting to possible future explorers.Exploring the solar system is the first step toward exploring the stars. The InSight probe will give us --well -- insight into whether this is something that humanity will achieve in the foreseeable future.And maybe Elon Musk's bet on him getting to Mars will become true. 5329
