On Monday, the NASA Mars InSight lander survived the "seven minutes of terror" during entry, descent and landing to safely arrive on Mars and took up permanent residence on the Red Planet. Unlike the rovers already on the Martian surface, InSight will stay put during its planned two-year mission.What will the stationary craft do until November 24, 2020?InSight has already been busy. Since landing, it has taken two photos and sent them back as postcards to Earth, showing off its new home. These initial images are grainy because the dust shields haven't been removed from the camera lenses yet.And late Monday, mission scientists were able to confirm that the spacecraft's twin 7-foot-wide solar arrays have unfurled. With the fins folded out, InSight is about the size of a big 1960s convertible, NASA said."We are solar-powered, so getting the arrays out and operating is a big deal," said InSight project manager Tom Hoffman at NASA's Jet Propulsion Laboratory. "With the arrays providing the energy, we need to start the cool science operations. We are well on our way to thoroughly investigate what's inside of Mars for the very first time."The solar arrays are key to helping InSight function. Although Mars receives less sunlight than Earth, InSight doesn't need much power to conduct its science experiments. On clear days, the panels will provide InSight with between 600 and 700 watts -- enough to power the blender on your kitchen counter, NASA said. During more dusty conditions, as Mars is known to have, the panels can still pull in between 200 and 300 watts.Within the next few days, InSight's 5.9-foot-long robotic arm will unfold and take photos of the ground surrounding the lander. This will help mission scientists determine where its will place instruments.This whole unpacking process as InSight settles into its new home will take about two to three months as the instruments begin functioning and sending back data.The suite of geophysical instruments will take measurements of Mars' internal activity like seismology and the wobble as the sun and its moons tug on the planet.These instruments include the Seismic Experiment for Interior Structures to investigate what causes the seismic waves on Mars, the Heat Flow and Physical Properties Package to burrow beneath the surface and determine heat flowing out of the planet and the Rotation and Interior Structure Experiment to use radios to study the planet's core.InSight will be able to measure quakes that happen anywhere on the planet. And it's capable of hammering a probe into the surface.This is why the information InSight sends back about its landing site is crucial. Creating a 3D model of the surface will help engineers understand where to place instruments and hammer in the probe, called the Mars mole HP3 by those who built it."An ideal location for our Mars mole would be one that is as sandy as possible and does not contain any rocks," HP3 operations manager Christian Krause said.Tilman Spohn, principal investigator of the HP3 experiment, said, "our plan is to use these measurements to determine the temperature of Mars' interior and to characterize the current geological activity beneath its crust. In addition, we want to find out how the interior of Mars developed, whether it still possesses a hot molten core and what makes Earth so special by comparison."The first science data isn't expected until March, but InSight will be sharing snapshots of Mars along the way. And InSight's magnetometer and weather sensors are taking readings of the landing site, Elysium Planitia -- "the biggest parking lot on Mars." It's along the Martian equator, bright and warm enough to power the lander's solar array year-round.The information InSight will gather about Mars applies to more than just the Red Planet. It will expand the understanding of rocky planets in general."This has important implications beyond just these two neighbors [Mars and Earth], as we are currently discovering thousands of exoplanets around other stars, some of which may be quite similar to Earth or Mars in terms of size, location and composition," said Jack Singal, a physics professor at the University of Richmond and a former NASA astrophysics researcher. 4251

Once the fissures open and the hot stuff starts flowing, it's best to not fight nature."The flows cannot be stopped, but people have tried in the past," said Benjamin Andrews, director of the Global Volcanism Program at the Smithsonian Nation Museum of Natural History.Flows can and have been diverted, though. The most famous example, Andrews cites, was in 1973 when the Eldfell volcano exploded on Heimaey, a small island in Iceland. 443

One possible scenario that Pac-12 officials are considering is that sports could return as early as mid-November.According to ESPN, the plan is the most aggressive among multiple options the league is considering.The report comes after the conference joined a partnership with Quidel Corporation that provides rapid coronavirus testing.The return to play is contingent on California and Oregon public health officials clearing athletes to resume practices.In August, Pac-12 officials suspended all sports for 2020.This story was first reported by Phil Villarreal at KGUN in Tucson, Arizona. 598

OMAHA, Neb. — Authorities in Omaha say two people died and two others are in critical condition after a home explosion and subsequent fire early Tuesday morning.Following the deadly explosion, it was discovered that the homeowner, 74-year-old Theresa Toledo, had filed a petition for a domestic abuse protection order against 27-year-old Alexander Toledo, stating her relationship as his grandmother. Theresa and her daughter, Angela Toledo, both died in the fire that broke out in the 4800 block of South 51st Street. A dog also was found dead at the scene. According to the Omaha World Herald, Alexander and another person who lived in the home suffered critical injuries.Theresa wrote in the petition, "Alex is on meth, mushrooms that I'm aware of, I haven't been able to see my grandchildren since summer because they are afraid of him as he talks to himself and says his stepfather is in his head, which is not true...he has put holes in the basement walls where he stays and you can't even walk in the basement. He has electronics in the walls & ceiling. I'm afraid he will start my house on fire."Toledo also described her grandson's alleged criminal history with narcotics. She concluded the petition by writing, "I need Alex out of my house now before he destroys my house or harms me, the drugs make him crazy."According to Omaha Fire Department Battalion Chief Scott Fitzpatrick, crews arrived on the scene at 8:15 a.m. Tuesday, with a second alarm called at 8:23 a.m. The entire block was initially evacuated before authorities determined there was no threat to other residents.The house that exploded is a complete loss and was leveled in the explosion. Some surrounding homes have extensive damage.Neighbors described the scene as horrifying and said it sounded like a bomb went off. "I heard a very loud explosion. It sounded almost like something was bombed and I flew out of the house thinking it was my house and when I got outside I could see the house was on fire and someone was running down the hill and saying to call 911," said Marianne Distefano, a neighbor. When fire rescue arrived at the scene, the house was engulfed in flames. "It was horrible. I mean it was just in flames and after that, smoke, but you could see it was bad. It looked like someone had bombed the house," Distefano said. Distefano saw one neighbor jump to action. Jeff Mell ran towards the flames when he saw what was happening. "I heard something fall, it sounded like something fell on our house, I thought it was a tree or whatever so I came out front angry and I looked down the street and saw flames coming and I automatically just started running," Mell said. He and another neighbor wrapped a man in blankets and helped him to a safer area. Fire investigators are probing the cause of the explosion. "There are so many variables to tell right now, that’s why we have to investigate and kind of piece it together to see exactly what it was that made that house explode. As you can see, the explosion was pretty big," said Fitzpatrick. The fire department said that this will be a lengthy investigation.Read related court documents filed on Monday below.This story was originally published by Alyssa Curtis, Danielle Meadows, Katrina Markel and other staff at KMTV. 3280
