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 (CNS) - A pedestrian was hit and killed while crossing an Oceanside highway late Saturday night, police said.The crash was reported to police shortly before 10 p.m. Saturday at the intersection of state Route 76 and Douglas Drive, according to Oceanside police Sgt. Rick Davis.Officers found a man lying unresponsive in eastbound lanes of Route 76.Davis said according to witness statements and evidence at the crash scene, investigators believe the pedestrian was crossing Route 76 from north to south against a red light, and was hit by a car heading east on the highway with a green light.The driver, who was not injured, immediately stopped and waited for police to arrive, Davis said. Police did not suspect alcohol or drugs were factors in the crash.The name of the victim was not immediately released. 826

Scripps Company, the parent company of this television station.CINCINNATI – One of the most iconic brands in television history will return when Katz Networks, part of The E.W. Scripps Company, relaunches Court TV – a new network devoted to live, gavel-to-gavel coverage, in-depth legal reporting and expert analysis of the nation’s most important and compelling trials.For more than 20 years, Court TV brought high-profile courtroom dramas, including the trials of O.J. Simpson, the Menendez brothers and Casey Anthony, into American living rooms. Continuing that legacy, the new Court TV network will launch in May 2019 and run 24 hours a day, seven days a week. It will be available for cable, satellite, over-the-air and over-the-top carriage.In rebooting Court TV, Katz Networks announced: 860

On Wednesday, the Supreme Court ruled in favor of expanding a clause that prevents the application of anti-discrimination laws from religious institutions.In a 7-2 decision, with liberal justices Ginsburg and Sotomayor dissenting, the court expanded the "ministerial exception," siding with a California Catholic school that did not renew the contracts of two teachers.In the case of Our Lady of Guadalupe School v. Morrisey-Berru, the teachers claimed they were discriminated against because they were released from their contracts after they did not receive certification in a Catholic teaching course. The teacher later sued, saying she had been discriminated against because of her age.However, the citing precedent from the landmark 2014 Burwell v. Hobby Lobby Stores, Inc. case, the court ruled that the school and other such institutions are protected from discrimination lawsuits. 896
