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

ODESSA, Texas (KGSTV) - A man with San Diego ties who survived the Texas shooting rampage Saturday is recounting the moment he drove into the crosshairs.Daniel Munoz, 28, moved from San Diego to Texas a year ago to work in the oil industry. He was in his car on the way to meet a friend for a drink, when he yielded to a car coming off an interstate. He immediately saw what appeared to be a rifle barrel in the hands of a driver and the shooter, Seth Ator.Earlier, the shooting spree had started with a routine traffic stop, when Ator suddenly started shooting at officers. During the ensuing chase in the Odessa/Midland area, he shot at other drivers. One of those drivers was Munoz. After he saw the rifle barrel, he told the Associated Press, "This is my street instincts. When a car is approaching you and you see a gun of any type, just get down. Luckily I got down … sure enough, I hear the shots go off. He let off at least three shots on me."Munoz believes one shot hit the engine, another struck the driver's side window, and a third hit a rear window. Some shattered glass punctured his left shoulder, causing him to bleed heavily. As he made the frenzied drive to a hospital, the shooting rampage continued.The gunman would hijack a mail truck, before ramming police vehicles outside a theater, where police would shoot and kill him. In the end, Ator would kill seven and injure 22. As for Munoz, he says he's physically okay but shaken."I'm just trying to turn the corner and I got shot. I'm getting shot at? What's the world coming to? For real? I'm just minding my own business," he told the Associated Press.Officials have identified another man, 62-year-old San Diegan, Marco Corral, as among the injured. 1731

One of Defense Secretary James Mattis' most senior civilian advisers is being investigated by the Defense Department Office of Inspector General for allegedly retaliating against staff members after she used some of them to conduct her personal errands and business matters, according to four sources familiar with the probe.Dana White, the Trump administration political appointee who serves as the Pentagon's chief spokeswoman, has been under investigation for several weeks after multiple complaints were filed against her.White is alleged to have misused support staff, asking them, among other things, to fetch her drycleaning, run to the pharmacy for her and work on her mortgage paperwork. Staffers also charge that she inappropriately transferred personnel after they filed complaints about her. 811

  

Ocasek was born in Baltimore. He and friend Benjamin Orr played in a number of bands before eventually officially forming the Cars in 1976. They released their self-titled debut album in 1978, which featured the hit singles “Good Times Roll,” “My Best Friend’s Girl,” and “Just What I Needed.” Following five more albums and hits like “Drive” and “Shake It Up,” the group broke up in the late 1980s.Starting with 1982’s Beatitude and ending with 2005’s Nexterday, Ocasek released a series of solo albums. He was also a producer of albums by artists including Weezer, Bad Brains, Suicide, Guided By Voices, No Doubt, the Cribs, Bad Religion, and others.The musician and producer was also a pop culture fixture beyond music. He made a memorable appearance in John Waters’ Hairspray as a painter. He was an artist in real life, too, and his work was shown in galleries. He also wrote books, including the 1992 poetry collection Negative Theater. He was a regular guest on “The Colbert Report,” once calling out Todd Rundgren on the show (at a time when Rundgren was fronting the Cars under the name “the New Cars”). He appeared on the 1140

  

Ohio and Michigan. Two states with intense rivalries, however when you visit, you can't help but think how much they are the same. With a combined 34 electoral college votes, both are swing states that will decide this election. Both have experienced economic hardship in recent decades and both still rely on the auto industry for jobs. Ahead of the first debate in nearby Cleveland, what are the candidates doing for the auto worker?UNION DEBATE"I am the president of UAW Local 14," Tony Toddy proudly says from his office in Toledo. Toddy, who has been with the UAW for years, recently took over the post. "We like Joe because we know Joe," Toddy says, speaking of the UAW endorsement of Joe Biden. Toddy believes Biden would listen to unions more if elected president. Toddy does not like the new trade agreement, USMCA, which President Donald Trump signed into law earlier this year. "It’s just NAFTA 2.0. Where are the jobs?" Toddy said. But Trump supporters say wait a minute. "I've worked for Ford Motor Company for 24 years," Terry Bowman, who serves as co-chair of the Michigan Republican Party, said. "The American worker deserves four more years of a Trump presidency," Bowman said. Bowman said while union leadership maybe backing Biden, many on the assembly line are backing Trump. Bowman says workers like Trump's tough tough talk and believe his new trade deal is better than the alternative. ON THE ISSUESSo how do the candidates want to help the auto industry? Biden wants to shift 300,000 government cars from gas to electric, believing government investments would generate 1 million new jobs. Trump says his new USMCA trade deal will create 100,000 new jobs and that his rollback of environmental regulations will result in cheaper cars. At Inside the Five Brewery near the Michigan/Ohio line, patrons are divided heading into the debate. "I am for Biden," Marge Mizer, said. "I like an upfront person that’s going to tell me the truth," Mizer said. Meanwhile David Bartlett says he wants Trump to send a message. "I want to see President Trump destroy Joe Biden in the debate," Bartlett said. 2123
