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

AZUSA (CNS) - A homeless man suspected of intentionally starting the Ranch 2 Fire in Azusa surrendered to authorities Sunday, while firefighters endured another day battling the blaze amid scorching temperatures.The fire, which grew to 2,256 acres overnight, was just 7% contained Sunday.The man suspected of intentionally starting the fire, 36-year-old Osmin Palencia, was in custody at the Azusa Police Department jail. Police did not release further information except to say that the investigation was still active, and urged anyone with information about the fire's origin to call 626- 812-3200.On Saturday, police said Palencia was believed to have a connection to the Monrovia area and possibly a woman known as "Madonna Ortiz." They added he is violent and has multiple active arrest warrants.Palencia also had four misdemeanor arrests over the last two years, three by Azusa police and one by sheriff's deputies, according to jail records.Palencia's last known residence is an encampment in the Azusa Canyon Riverbed, police said.A witness who lives in a riverbed near Mountain Cove told NBC4 an argument between two homeless men sparked the fire."There were two gentlemen in the back (of a homeless encampment) fighting and they were arguing over a bike and one guy said he'd burn the other guy out, and things got escalated to where the fire started," evacuee Jimmy Pockets told the station. "Ran over to try to put it out but it just took off so quick."Firefighters said high temperatures, slope, aspect and winds "came into alignment" overnight, causing the fire to became very active at the bottom of Roberts Canyon and move upslope amid dense mixed-chaparral fuels, sending a large pyrocumulus cloud formation into the sky that could be seen throughout much of the Southland.Firefighting aircraft were grounded for the night Saturday due to a drone flying in the fire area that was spotted at 6 p.m. Officials noted that there is a temporary flight restriction in the vicinity, and flying drones there is illegal.All earlier evacuations orders have been lifted, but the following road closures remained in effect:San Gabriel Canyon Road/Highway 39: closed at Northbound Hwy 39 at Sierra Madre Avenue (southbound Highway 39 is closed at East Fork Road)Glendora Mountain Road: closed from Big Dalton to East ForkGlendora Ridge Road: closed from Glendora Mountain Road to Mt. Baldy RoadSanta Anita Canyon Road: closed from Arno Drive to Chantry Flats RoadThe Angeles National Forest changed its Forest Fire Danger Level from very high to extreme, and moved into full fire restrictions including prohibiting campfires in developed sites. Cooking stoves, lanterns and similar devices that use propane, white gas or similar fuels were prohibited.The Ranch 2 Fire was reported about 2:45 p.m. Thursday near North San Gabriel Canyon Road and North Ranch Road, according to the Azusa Police Department and Los Angeles County Fire Department, which called in a second- alarm response.The number of personnel committed to fighting the blaze had reached 286 Sunday. 3076

At least 10 people have died after flash flooding hit the Aude region of southern France, local officials said Monday.Roads were cut off and cars overturned after three months' worth of rain fell in six hours overnight Sunday into Monday, causing rivers to flood.An 88-year-old nun was killed after water swept through a nunnery in Villardonnel, while four people died overnight in nearby Villegailhenc.The death toll was lowered by the Ministry of the Interior, after initially being placed at 13. Another person is missing and five are seriously injured, officials said.Seven hundred firemen and seven helicopters have been mobilized in response to the flooding, which has reached unprecedented levels in the Aude valley, according to France's flooding watchdog, Vigicrues. 783

AUSTIN, Texas (AP) — A federal judge has ruled that Texas’ statewide mask mandate must extend to inside polling places. But election officials Wednesday did not appear to be rushing to enforce the order. It was handed down after more than 8 million people have already cast ballots. U.S. District Judge Jason Pulliam said not requiring face coverings in Texas polling places created a discriminatory burden on Black and Latino voters, who are at higher risk of death and severe illness from the coronavirus. Texas Governor Greg Abbott had included an exemption for polling places in his statewide mask mandate. The governor said he encourages people to wear a face mask but exempted polling places from the mandate because he didn't want voters turned away from the polls just because they didn't have a mask, according to the Texas Tribune. Texas Attorney General Ken Paxton immediately appealed Tuesday’s ruling. Texas is three weeks into early voting, but Pulliam said enforcing a mask order would not be disruptive.According to the U.S. Elections Project, which is tracking early voter data, there have been more than 8.1 million votes cast already in Texas as of Wednesday afternoon. That's roughly 90 percent of all votes cast in the 2016 election. 1263
