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 number of coronavirus cases continues to climb around the world and disrupts the travel industry, Princess Cruises has announced cancellation of early 2021 trips.“Due to restrictions and limitations with border and port access determined by government and health authorities and the continued uncertainty of airline travel,” Princess Cruises canceled about 30 voyages on two ships.The Island Princess, which stopped at ports around the world, and Pacific Princess, that sailed around South America and Australia, will not set sail until at least April, according to a release from the company.The cancelled voyages include a 111-day around-the-world from Los Angeles.Princess Cruises, which is owned by Carnival, is offering refunds or credit for a future cruise.Carnival Cruises has also canceled some 2021 voyages, and likely won’t return to full capacity until 2022.The cruise company is facing legal action for their handling of passengers when the coronavirus pandemic started this spring. Two lawsuits allege Princess Cruises did not act fast enough to impose quarantines when cases were discovered.When the lawsuits were filed in June, Princess Cruises told USA Today “our response throughout this process has focused on the well-being of our guests and crew within the parameters dictated to us by the government agencies involved and the evolving medical understanding of this new illness.” 1414

As we're all focused on the current rollout of the COVID-19 vaccine, a technology known as thin-film freezing is getting a lot of attention. It's groundbreaking and could change the way we administer drugs or use medicine in general.You've probably heard about the need to keep the COVID-19 vaccine cold. It has to be so cold, in fact, that the shipment and transport are challenging. Well, what if that vaccine could be turned into powder?“What we’ve most recently been working on is the elimination of cold chain by storing as a powder, a dry powder where the drug is much more stable than if it was stored as a liquid or as a frozen liquid,” said co-inventor Dr. Robert Williams.Williams said it would eliminate the need for extreme cold storage and transport. The technology isn't new. He got a research grant and came up with it about 15 years ago.Williams, who is also a pharmacy professor at the University of Texas in Austin, said they were working on the technology and its multiple uses when the pandemic hit. And all of a sudden, they got a lot of attention.“We have published over 70 papers on the technology and using it for different products- it’s quite a mature process," Williams said. "We developed it because with other vaccines, the majority of the vaccine cost is in wastage because of this cold chain issue, so we published several key papers where we showed our thin-film freezing technology would protect vaccines - and you wouldn’t need cold chain storage.”Glenn Mattes, President, and CEO of TFF Pharmaceuticals added that the powders can be converted to topical preparations and they are currently working with the US Army to take some of the preparations and would then administer them directly through the eye.TFF is launching thin-film freezing into development through the FDA process. “I use the term ubiquitous because it is and disruptive because it is,” Mattes said. He added that they've explored their technology in the cannabinoid realm. But, as for the COVID vaccine, they're aiming for a second-generation usage.“To truly eradicate the pandemic, you have to have a global response," Mattes said. "The companies we’ve been speaking to certainly recognize the broad utilization of the technology but the application to the developing world, rural area, remote areas, where you can take a powder and inhale it or take the powder and reconstitute it has tremendous potential."Experts say it is only just the beginning as they launch their technology into a new world. 2511

AURORA, Colo. — Police detained and handcuffed a Black mother and four children after mistaking their SUV for a stolen motorcycle from another state.It happened in the parking lot of a shopping center off of Buckley Road and East Iliff Ave. Sunday morning."Why are you now placing these children on the ground face into the concrete? It's hot! In front of all of us? Screaming at them. They are telling you they are hurt," witness Jenni Wurtz said.Wurtz recorded the incident along with several other witnesses.She says a police car slowly pulled behind the family. The officer drew their weapon on the family and ordered them out of the car. Several of the children were handcuffed."That makes me very mad because I am not anti-police. I'm anti- what happened yesterday, and that was ridiculous," Wurtz said.The car the family was driving was not stolen. Police used a license plate scanner to gather information on vehicles in the area. They should have been looking for a motorcycle with the same plate from another state.Interim Aurora Police Chief Vanessa Wilson blamed the license plate reader, but could not explain why the dozens of officers who responded did not confirm the vehicle description."I totally understand that anger, and don't want to diminish that anger, but I will say it wasn't a profiling incident. It was a hit that came through the system, and they have a picture of the vehicle the officers saw," Wilson said, defending her officers' actions.After officers realized the mistake, the family was uncuffed, but more officers continued to arrive. Video shows more than a dozen officers standing around the traumatized family."I do not think a stolen vehicle is worth traumatizing the lives of children. On top of that, I was 20-feet away with a drawn gun. They didn't even tell me to move, secure the scene. They didn't do anything," Wurtz said.Wurtz filed a complaint with internal affairs. She believes the police department's policy needs to change.By Monday evening, an internal investigation was underway following the incident, according to Wilson. She released the following statement on Monday."We first want to offer our apologies to the family involved in the traumatic incident involving a police stop of their vehicle yesterday. We have been training our officers that when they contact a suspected stolen car, they should do what is called a high-risk stop. This involves drawing their weapons and ordering all occupants to exit the car and lie prone on the ground. But we must allow our officers to have discretion and to deviate from this process when different scenarios present themselves. I have already directed my team to look at new practices and training. I have called the family to apologize and to offer any help we can provide, especially for the children who may have been traumatized by yesterday's events. I have reached out to our victim advocates so we can offer age-appropriate therapy that the city will cover."Sunday's incident comes as the Aurora Police Department faces continued criticism over its handling of the death of Elijah McClain. McClain died in police custody in 2019, but the case has garnered nationwide attention amid widespread protests in favor of police reform.This story was originally published by Jessica Porter on KMGH in Denver. 3318
