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

OCEANSIDE, Calif. (KGTV) -- A dramatic arrest of a man following a police pursuit that started in San Juan Capistrano and ended in Oceanside.The California Highway Patrol said it all started around 11 p.m. Sunday night when officers attempted to pull over a silver car that was weaving and traveling with no lights on Interstate 5. The driver never stopped, leading officers on a pursuit for about 20 minutes.When the chase entered San Diego County, CHP officers used a spike strip to slow down the car near Camp Pendleton, with the Carlsbad Police Department's help.The car eventually pulled into the center divider at Oceanside Blvd., but the driver refused to come out. Officers used munitions to break the back window and had a K-9 drag the man out.The driver was resisting arrest and had to be wrestled onto a gurney and taken to the hospital.No officers were injured. All southbound and northbound lanes of the I-5 were closed for about half an hour. 964

ORLANDO, Fla. (AP) — Carole Baskin of “Tiger King” fame is being sued for defamation by a former assistant. As part of the lawsuit, the daughters of Baskin’s former husband are seeking more information about what happened to their father, who disappeared mysteriously more than two decades ago. The amended complaint to an earlier lawsuit was filed Tuesday in state court in Tampa by Don Lewis’ three daughters as well as his former assistant, Anne McQueen. The lawsuit says Baskin defamed McQueen by posting a video diary entry on YouTube earlier this month in which she says McQueen played a role in Lewis’ disappearance. Lawyers for Baskin said they couldn’t comment on pending litigation. 700

ORLANDO, Fla. -- Orlando took a direct hit from Hurricane Irma Sunday, but the "happiest place on Earth" is on track to reopen Tuesday. Walt Disney World took a few hits, but managed to avoid the wrath many other Florida businesses experienced as the storm pummeled the state. 304
