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 boy who went missing Wednesday night from Oceanside has been found safe, police said. According to police, 12-year-old Xavier Nolasco disappeared from Madison Street around 7:30 p.m. He was later located around 9 p.m. At this time, it's unclear where he was found, but police placed urgency on finding the young buy due to his diabetes and mental illness. 394

OCEANSIDE, Calif. (KGTV) - A 16-year-old girl told Oceanside Police a man, possibly homeless, tried to kidnap her Thursday morning as she walked to El Camino High School. The girl was walking east on Mesa Drive near Vanilla Way at 7:20 a.m. and passed the man heading the opposite direction. After she walked by, the man turned and grabbed her in a bear hug, police said. The man struggled with the girl, who was able to break free when he fell to the ground, according to investigators. The girl arrived at school and notified security about the incident. Oceanside Police units and a drone were deployed to find the man but were not successful. The girl described the man as dirty or "possibly homeless" according to police, white, in his 50s, 5’9 inches tall, and very thin. He was wearing a tan pullover sweatshirt with a zipper and baggy black jeans. Police said the man may be bald on top of his head with short light brown hair on the sides. He also had a scab on the right side of his neck, the girl reported. Oceanside officers are asking anyone with information to call the department’s Family Protection Unit at 760-435-4690. 1144

OCEANSIDE, Calif. (KGTV) - A desperate mother is making a plea for tips after a thief snatched her van, a "lifeline" for her special needs daughter.Veronica Lara lives on Harrison Street. Her 7-year-old daughter, Sophie, suffers from Cerebral Palsy, Epilepsy, and a rare chromosomal disorder called Pallister-Killian Mosaic Syndrome. A year ago, her family spent ,000 making her 2015 Toyota Sienna wheelchair accessible."It's my daughter's lifeline. We can't go anywhere without it," said Lara.On Tuesday night, with the family inside the home, someone stole it between 9 p.m. and 9:30 p.m. That van is needed for Sophie's many medical appointments.RELATED: NFL game result may have fueled Fallbrook vandalism, destruction of truck"At this point, I will have to cancel her appointments, because I have no mode of transportation for her," said Lara.The loss is not just about getting places. Sophie loves being in the van and getting out of the house."She laughs a lot. She likes looking around and seeing the lights go by," said Lara.Lara worries those laughs will be less frequent.RELATED: Police investigate multiple carjackings in El Cajon"That saddens me. Anything that makes her happy fills my heart with joy," said Lara.Joy is not the word to describe her family's past month. In early November, her husband Juan was shot in Tijuana while waiting at a taco stand. "Armed carjacking ended where he was. He ran, but many people got shot," said Lara.Juan survived gunshots in his hand and stomach. He is no longer able to work as a tow truck driver, which will squeeze the family's finances."I'm still standing strong. I'm a strong momma, but this special needs family has gone through a lot, and this just added to my grief and anxiety ... You don't know what to say anymore," said Lara.Lara's van is insured, but it's not clear how much, if any, of the wheelchair conversion cost will be covered.Anyone with information is asked to call Oceanside Police at 760-435-4900.A Gofundme campaign has been set up to help family with expenses. 2051
