Attorney General William Barr compared calls for a national lockdown to slavery on Wednesday.Speaking at Hillsdale College, the event's host asked Barr to explain the "constitutional hurdles for forbidding a church from meeting during COVID-19."Barr then launched into a four-minute response where he said a national lockdown would be akin to house arrest.He accused state governors of using their executive powers to stifle citizens and businesses."Other than slavery, which was a different kind of restrain, this is the greatest intrusion on civil liberties in American history," Barr said.The attorney general said he's OK with requiring masks, but not shutting down businesses.The comments came a day after Barr equated prosecutors at the Justice Department to pre-schoolers. 787
AUSTIN, Texas (AP) — The chairman of a panel considering changes to the U.S. military draft said Monday its recommendations to Congress won't be influenced by a federal judge's recent ruling that the current system is unconstitutional because it only applies to men.The military has not drafted anyone into service in more than 40 years, but American men must still register when they turn 18. Recent efforts to make registration also mandatory for women have set off intense debate in Washington.U.S. District Judge Gray Miller declared a male-only draft unconstitutional in his ruling late Friday, but he stopped of ordering the government to make any immediate changes. He said the time for debating "the place of women in the Armed Forces" is over. Women now make up 20 percent of the Air Force, 19 percent of the Navy, 15 percent of the Army and 8.6 percent of the Marines, according to Pentagon figures.The Justice Department declined comment Monday after losing the case out of Houston.RELATED: Federal judge rules male-only draft is unconstitutionalThe decision comes as Congress awaits a report next year from an 11-member commission to study the issue of selective service. It is chaired by former Nevada Rep. Joe Heck, who personally supports that women also be required to register for the draft.Heck said the ruling won't influence its report or hurry along the eventual recommendations to Congress. He described a generational divide in public comments his commission has collected about women and the draft."If you talk to those who would be impacted, that is males and females ages 18 to 25, they say, 'yes, women should have to register. It's a matter of equality,'" Heck said. "If you talk to an older population, they're the ones who seem to be reluctant."RELATED: Generals push for women draft registrationThe lawsuit in Texas was brought by the National Coalition for Men, a men's rights group. The Defense Department lifted the ban on women in combat in 2013, and Miller stopped of ordering the government to take any immediate action with the draft in his ruling late Friday."I actually thought the judge did that to give them time, because this is such a major change," said Marc Angelucci, a lawyer for the men's group.The last major decision on selective service was the U.S. Supreme Court ruling in 1981 that upheld excluding women because they were not allowed to serve in comment at the time.Miller, who was appointed by former President George W. Bush in 2006, noted that was no longer the case."While historical restrictions on women in the military may have justified past discrimination, men and women are now 'similarly situated for purposes of a draft or registration for a draft,'" Miller wrote. "If there ever was a time to discuss 'the place of women in the Armed Services,' that time has passed." 2843

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
As the NBA prepares to resume the 2020-21 season tomorrow, basketball commissioner Adam Silver told Good Morning America on Wednesday that the league would “cease completely” if an outbreak of the virus occurred within the league.Silver’s comments come as baseball’s Miami Marlins has had a number of its players and coaches test positive for the virus in recent days, forcing the team to suspend play for the week. Likewise, the Philadelphia Phillies, which played the Marlins last weekend, have suspended several games this week.“it’s not an exact science because nobody’s ever done this before,” Silver said. “I think we have plans in place where we might pause, similar to what baseball is doing now. Probably, if we had any significant spread is immediately stop. One thing we’d try do is try to track those cases to determine where they’re coming from and whether there had been spread on campus. Ultimately, I think we would cease completely if we saw that it was spreading around the campus and something more than an isolated case was happening."Unlike baseball, basketball has kept its players in a “bubble” in Orlando, Florida. Even though the virus is circulating through the state, the latest round of COVID-19 tests showed no players or coaches tested positive for the virus in Orlando.But that hasn’t stopped Silver from being anxious about the resumption of play. After all, it took just positive test, Utah Jazz star Rudy Gobert, to shut down the league back in March.“There is a high case rate in Florida down in Orange County, where Orlando is, as well obviously what is happening in baseball with the Marlins, so it is something we are keeping track of very closely,” Silver said. “We have confidence in this protocol that we designed… Everyone that is on that campus is tested on a daily basis.”The MLS and NHL have followed similar plans by isolating players. Both leagues have in recent days not reported any COVID-19 cases. The MLS had two teams withdraw from its mid-season tournament due to the spread of the virus, but has been virus free for two weeks. 2089
As wildfires rage across the western part of the country, firefighters are doing their best to contain the flames and prevent further devastation. Most of the fires are burning in areas that haven't seen a wildfire in a long time, making the loss of life and land even worse."It's been difficult. This is becoming all too common. Another record-breaking, severe, unprecedented fire season here in Colorado. And this was the largest forest fire in the White River National Forest history," said Forest Supervisor Scott Fitzwilliams, speaking about the Grizzley Creek Fire. Fitzwilliams says not all wildfires cause complete destruction. In fact, many provide some crucial ecological benefits. Take the big horn sheep who live in the forest. "Their defense mechanism is those big eyes on the sides of their heads so they can see predators coming. And so, they will abandon a habitat when there's too many trees and too much brush and so in many areas of the canyon, this fire improved big horn sheep habitat," said Fitzwilliams.The Grizzly Creek Fire also burned the top of a canyon, helping the habitat for elk and deer. A silver lining to the Grizzley Creek Fire, which also charred creeks that provide drinking water for an entire town in Colorado and was unexpectedly slowed by an early snowfall in the area.At Sequoia and Kings Canyon National Parks in Central California, fire officials conduct what they call "prescribed burns.""A prescribed burn is literally us giving a prescription to the forest," said Mike Theune, Fire Information Officer for Sequoia and Kings Canyon National Parks. Prescribed burns are slow and steady, clear out unnecessary brush and naturally revitalize a forest, he says.Theune and Fitzwilliams say, for more than 80 years, fire services across the country used to put out any and all fires, even if they occurred naturally, such as from lightning."[In the] early 1900s when forest service came into view and smokey bear and we thought we needed to put out all the fires and we did. And we did a great job of it and Smokey Bear was the best spokesperson we could ever ask for but what that did is significantly change the landscape as far as the density of vegetation," said Fitzwilliams."We need to restore that ecosystem to what those natural levels are and one of the ways we can do it is through a very measured and very managed scientifically based approach to prescribed burning," said Theune.Theune says not all national forests in the country need prescribed burns as there are some states that deal with too many forest fires. National parks and forests officials say it's important to evaluate each individual ecosystem's needs in order to preserve their beauty for years to come. 2730
