AUSTIN, Texas (AP) — The Austin City Council has voted to cut one-third of the city's 4 million police budget amid national calls for "defunding" law enforcement in favor of spending more money on social services. Council members voted unanimously Thursday to reallocate just over 0 million in the 2021 fiscal budget to social services. That budget starts Oct. 1. Of that, million will fund community resources including response to the coronavirus pandemic, mental health aid programs, victim services, and food, housing, and abortion access in October. Approximately million will be redistributed to similar city services over the year. Another million will be spent on alternative forms of public safety and community support. 755

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

ATLANTA (AP) — Georgia’s governor, Brian Kemp, is explicitly banning the state's cities and counties from ordering people to wear masks in public places.He’s voiding orders that at least 15 local governments across the state had adopted even though Kemp had earlier said cities and counties had no power to order masks.The Republican governor has instead been trying to encourage voluntary mask wearing.An increasing number of other states have ordered residents to wear masks in public, including Alabama, which announced such a ban Wednesday.Kemp’s move is likely to infuriate local officials in communities that had acted, including Atlanta, Augusta, Savannah, Rome and the governor’s hometown of Athens-Clarke County. 729

BALTIMORE — Romance scams have nearly doubled this year, according to the FBI. The holidays coupled with the pandemic have many people feeling lonely. Dating sites help singles connect, but it's not always who you think it is.A Montgomery County man thought he was in a relationship with a woman named Brandy Bowens, instead, he lost ,000 in a romance scam. "It’s like there are claws in you that you can't seem to get out," he said.He didn't want to be identified but wants to warn others about how his five-year relationship ended in financial ruin."It's hard. I lost the money and it messed up everything in a financial way for me, trying to build my credit back, just so much that that has screwed up for me," he said.His better judgment took a back seat when he was asked to be the go-between for the woman's art business. The FBI later informed him that he was involved in a money-laundering operation."That's a huge problem and continues to be a problem," said Supervisory Special Agent Keith Custer with the FBI Baltimore field office.Custer estimates that romance scams are up 30 to 50 percent. It's also one of the highest dollar value scams, and victims rarely get their money back.Custer is warning anyone with an online dating profile to research the person's photo and profile. Start by doing a reverse google image search, and look for scammers to make up excuses on why they can't meet in-person or video chat."Saying my phone is broke or my camera doesn’t work," the Montgomery County man said.And never send money to anyone you don't know personally."More people are being isolated and are online looking for companionship, so naturally that fraud and those scams are going to continue," said Custer.If you think you might be a victim of a romance scam, contact your local FBI office or file a report online.This story was first reported by Mallory Sofastaii at WMAR in Baltimore, Maryland. 1920
