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

Back-to-school shopping is an expensive chore in a normal year; this year is anything but normal. But with August upon us, stores are putting out back-to-school displays in anticipation of children needing to learn, whether in the classroom or at home.Two-fifths (40%) of parents with children in K-12 or college anticipate their children will be attending classes in a hybrid environment (both in-person and remote) in the fall of 2020, according to a new NerdWallet survey conducted online July 16-20 by The Harris Poll among over 600 parents. Planning for multiple scenarios could result in the need for increased back-to-school spending, but many may not have the extra money this year.Nearly half (47%) of parents expect they’ll spend less on back-to-school shopping than they otherwise would, due to the coronavirus pandemic, according to the survey. Of them, 40% say it’s because their household income has been affected by the pandemic and related economic effects.On the other hand, one-fifth (20%) of parents expect to spend more this year on back-to-school purchases than they otherwise would, due to the pandemic. Of them, 54% think they’ll be spending more to outfit a home learning environment, and 50% will be spending more to account for supplies for both in-person and at-home learning.“Saving on back-to-school shopping takes some strategizing in a normal school year, but this year poses unique challenges: Not only is it harder to know what students might need, but many families are eyeing big purchases to make remote learning easier, including electronics and desks,” says Kimberly Palmer, personal finance expert at NerdWallet. “At the same time, many families have less room in their budget to make new purchases because of the pandemic.”1. Shop for the short termWhether you’re spending less this year out of necessity or you’re anticipating having to spend more: Buy only what you need. If 2020 has taught us anything, it’s that well-laid plans can change. So purchase what you need to get the school year started and plan to supplement those purchases as the semester unfolds. You may find that some items get less expensive as the seasons change.“Unless you have your eye on a specific type of computer or another item that could sell out, it’s OK to wait to make your purchases until after the school year begins — in fact, that’s when you see many of the best deals,” Palmer says.2. Take advantage of credit card rewardsMore than half (53%) of parents who will back-to-school shop this year plan to use a credit card on those purchases, according to the survey. Putting your expenses on a cash-back credit card could put your money to work for you. You may even reap enough to cover next year’s back-to-school expenses entirely. Just make sure you’re able to pay off the balance each cycle, as interest can quickly negate any benefits.3. Check prices before and after shoppingPrice matching involves comparing identical items at other stores and asking a retailer to match a lower price. The trick may not make sense for a package of pencils, but for clothing, electronics and other higher-dollar items, a successful price match could save you tens of dollars, if not more.Check a retailer’s website for its price matching policy details. Many will also refund the price difference if you spot a cheaper price within a certain time frame after the purchase.4. Team up to buy in bulkRegardless of where your child is learning this fall, they’ll need supplies that other students are also after. By teaming up with other parents, you can purchase things like hand sanitizer and supplies for homework and note-taking in bulk. If your child’s teacher is reluctant to give out parents’ contact information, ask if they would send out yours in a group email so other parents can reach you if they’re interested in group savings.“With many parents focused on at-home learning, you can also find savings by teaming up with other families in your neighborhood on purchases,” Palmer says. “Some communities are forming ‘pandemic pods’ to share the burden of teaching at home and keep kids socialized — pooling school supplies across the pod can spread the expenses and make them more manageable.”5. Shop on tax-free holidaysSixteen states are having sales tax holidays in August 2020. Most of them last through a full weekend, and some even longer. Retailers that offer online ordering for in-store pickup may require you to order and pick up on those particular days to reap the tax-free benefits. The specifics of each state’s holiday vary, but generally, they allow you to purchase certain back-to-school items without paying sales tax.6. Practice and teach thriftinessIf money is very tight, your child might be able to reuse some of last year’s supplies such as their backpack or leftover pencils and notebooks. You can also shop secondhand on sites like Poshmark or thredUP for clothing throughout the school year. And don’t be afraid to ask for help — many schools are putting programs in place that help outfit homes with the technology needed for remote learning.If your child isn’t accustomed to having to make sacrifices like this, use them as a teachable moment. Older kids can learn the complexities of managing a budget, a tool they’ll need in adulthood, and younger ones can learn what saving money means and help you search for the lowest prices.“Some communities are also organizing online volunteer opportunities for high schoolers to help match up with elementary school children who need extra help, which can be a great way to provide learning opportunities to both age groups in a safe, free way,” Palmer adds. “This school year will be unlike any other, which means parents and children will have to get more creative with stretching their back-to-school budgets.”More From NerdWalletWhat to Know Before Laying Down Money for a MattressWhat to Buy (and Skip) in FebruaryHere’s When Everything Will Go on Sale in 2020Elizabeth Renter is a writer at NerdWallet.

BABSON PARK, Fla. — A second university in Polk County, Florida has announced that they will be joining a program that will allow its staff and faculty to legally carry guns on campus.The announcement comes just eight days after a gunman opened fire on a Florida high school killing 17 people.The Polk County Sheriff's Office, in partnership with Webber International University, is establishing the Sheriff's Sentinel Program to enhance the safety of an already safe and secure community of students, faculty, staff, and guests at the University's campus in Babson Park, Florida."Prayers are not enough," Polk County Sheriff Grady Judd said in a press conference on Thursday. “The only thing that stops a bad guy with a gun is a good guy with a gun."Sheriff Judd explained that each teacher or staff member will have to go through extensive training through the program before they are given a gun."My babies — your babies — are in that classroom, and that active shooter is coming down the hallway with that thousand yard stare and that gun in their hand, do you want somebody to step out and stop him? Or do you want him to go into the classroom and slaughter your babies?" 1194

As White House advisers and congressional leaders spar over the next round of stimulus funds, President Donald Trump said on Tuesday that he still has some issues with the Senate GOP's proposal released yesterday.On the mind of so many Americans are stimulus checks, unemployment and the return to school.But when asked specifically what he disagreed with, Trump punted. Despite a Trump administration push for the return of in-person learning, a number of school districts across the US have announced plans to begin the 2020-21 school year virtually. On Tuesday, Ohio’s largest district Columbus City Schools said they will start the year off virtually.Trump has said that federal funds should only go to schools that are open.Meanwhile, the next round of stimulus is being debated on Capitol Hill. While it appears there is agreement between the White House, House Democrats and Senate Republicans on providing a second round of ,200 checks for most Americans, there is intense debate on unemployment. Last week, millions of unemployed Americans stopped receiving a 0 weekly supplement to unemployment checks. Those checks were in addition to state unemployment payments.With those payments no longer being received by Americans, there are questions on the state of the economy given an unemployment rate of 11.1 percent – nearly three times higher than at the start of the year.HIGHLIGHTS OF THE ACT:- ,200 stimulus checks for the same group of Americans who received a check in the spring- 6 billion in funds for schools to hire staff and conduct social distancing- Replenishing the Paycheck Protection Program, intended to help businesses keep employees on payroll- Extending unemployment supplement, although at a lower amount- Liability protection for businesses reopening amid the pandemic 1816
