Babies have such a bad reputation when it comes to staying quiet on plane rides that some parents go so far as to hand out treats to fellow passengers before the plane has even taken off. Indeed, George and Amal Clooney, world travelers and parents of twin babies, made headlines late last year for gifting headphones to some passengers, along with a note apologizing in advance for any crying.While there’s no need to pack dozens of gifts in your diaper bag, travel and parenting experts recommend other strategies to increase your chances of a smooth flight with your baby. 603

As wildfires scorch parts of the country, COVID-19 has sidelined a critical group of firefighters: prison inmates. The shortage comes as states are on pace for what could be a relentless fire season.CalFire, the state agency tasked with fighting and preventing wildfires in California, has already responded to over 4,100 fires as of June this year. Compare that to an average of 2,500 in recent years.“This year, we’re seeing something more typical of year’s past, we’re seeing these small starts that are growing into bigger fires," said Thomas Shoots, a CalFire public information officer. "We have a 25,000-acre fire burning up in Fresno now.” Responsible for protecting millions of acres across the state, CalFire relies on help from crews of inmates from the California Department of Corrections and Rehabilitation.“These are inmates who’ve chosen to help out California by joining these fire crews, and they’re a huge resource for the state,” said Shoots.Roughly 2,200 prison inmates are trained to work on the fire line, but COVID-19 has depleted their ranks.Of the state’s 118 staffed crews, 41 were quarantined because of prison outbreaks as of July 16, eliminating hundreds of firefighters at a critical time.States like Arizona, Colorado, Washington State, and Oregon also deploy inmates to wildfires, but in far fewer numbers than California.“We’re sitting much shorter than we have been in the past, but we’ve also taken a lot of aggressive steps to make sure we have enough folks for when these fires happen,” said Shoots.The state is hiring 858 paid firefighters to fill the void. They could also turn to the California National Guard and out-of-state resources if needed.“It continues to be a concern that COVID-19 could come in and decimate our staffing, but that hasn’t happened because we’re taking every precaution we can.”Like wildfires, COVID-19 has proved destructive and unpredictable, but firefighters stand ready to battle them both. 1968

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

AUSTIN, Texas (AP) — A holiday display meant to re-create a scene from "National Lampoon's Christmas Vacation" looked a little too real and caused a veteran to spring into action.The Heerlein family placed a dummy representing Clark Griswold dangling from the gutter of their Austin, Texas, home, with a ladder tipping beneath him.A veteran passing by thought it was the real thing and wrestled the ladder up while shouting, "Can you reach it?"KVUE-TV reports the man called police, who arrived and advised the family they were getting calls about the display.RELATED: Ohio man channels Clark Griswold, recreates Christmas Vacation lightsThey have since put up a sign that says "Clark G is part of our Christmas display please do not call 911." 752

At least five Marines assigned to the prestigious ceremonial Silent Drill Platoon in Washington were placed in pretrial confinement in recent days due to allegations they were involved in hazing at least one Marine at the unit, according to three defense officials.Hearings that took place this week resulted in one Marine being released from confinement but all could still face charges as the Naval Criminal Investigative Service has taken over the matter.The number of alleged victims has not been made public but the allegations came to light when one Marine came forward. Officials say a video had been made allegedly showing some Marines hitting at least one other Marine. It is not publicly known if that victim is the Marine who came forward.The platoon is a 24-man rifle unit that performs a drill exhibition largely in silence. It was founded in 1948 and performed for presidents and top officials as well as communities around the country tossing and spinning 10-pound M1 rifles with fixed bayonets.Multiple performances of the drill team were canceled in recent weeks due to the ongoing investigation, according to officials. The Marines did not publicize the reason for those cancellations or which performances were affected. The Marines said they began an investigation immediately at the unit, before turning it over the NCIS.The unit and the Marines are well known in the Washington community where they reside. In September they gained attention when several Marines ran to a nearby apartment complex to help rescue elderly residents when it caught fire. 1580
