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

Officials are investigating a deadly plane crash near 7th Street and Deer Valley Road on Monday morning. The FAA says the aircraft involved is a single-engine, home-built Acroduster. It reportedly crashed in the intersection around 6:50 a.m. under unknown circumstances. One person was killed and another was injured, according to Phoenix aviation officials. Phoenix Fire says they took the surviving victim, a man, to the hospital in critical condition. Video from the scene showed emergency crews working around debris in the roadway near several damaged cars. Police told media on scene the vehicles had substantial damage but no one on the ground was hurt. The area is shut down to drivers and there is no estimated time to reopen.

On Election Day, TikTok says it will limit premature victory claims until the Associated Press has declared a result.The company said in a press release that they are doing this to make sure no one is intimidated or suppressed by voting.The social media company added that they'd be partnering with fact-checkers to "reduce discoverability of content that prematurely claims victory in a race" before results are confirmed.TikTok says if the results cannot be verified or fact-checking is inconclusive, they will limit the content's distribution.The company added that they'd also add a banner that'll point users to its election guide on content with unverifiable claims about voting, premature declarations of victory, or attempts to dissuade people from voting by exploiting COVID-19 as a voter suppression tactic. 825

On Tuesday, president-elect Joe Biden will formally introduce his picks to head up several key positions in his presidential administration from his transition headquarters in Wilmington, Delaware.During his remarks, Biden confirmed reporting on his choices to fill six key roles in his upcoming administration.Watch the remarks in the video below: Biden's future nominees include:Anthony Blinken, former deputy national security adviser, for Secretary of StateAlejandro Mayorkas, former Deputy Secretary of Homeland Security, to lead the same agencyAvril Haines, former Obama Principal Deputy National Security Advisor, for Director of National IntelligenceLinda Thomas-Greenfield, a longtime member of U.S. Foreign Service, to serve as U.S. ambassador to the United Nations.Jake Sullivan, Biden campaign policy adviser, as National Security AdviserJohn Kerry, former Secretary of State and Democratic presidential nominee, to be Special Presidential Envoy for Climate.Reports have also surfaced in recent days that Biden intends to nominate former Federal Reserve chair Janet Yellen as the Secretary of the Treasury, though he did not make such an announcement on Tuesday.Biden's selections represent a return to a reliance on career bureaucrats and longtime Washington policy advisers for top executive branch positions. Throughout his term, President Donald Trump has filled top posts in his administration with candidates from the private sector.Biden's press conference will take place less than a day after the General Services Administration ascertained him as the winner of the 2020 election. The move grants Biden access to key information, like the daily presidential brief, and funds that can be used to begin hiring key positions.Cabinet-level positions require Senate confirmation, meaning that depending on the outcome of two runoff races in Georgia in January, Biden may face challenges in filling top positions. Democrats will need to win both Senate races to reach 50 seats in the Senate, and would then control the chamber as Vice President Kamala Harris would hold the tie-breaking vote. 2115

Online shoe retailer Zappos will allow customers to buy just one shoe, or a pair of shoes in different sizes.The change, being tested this week on their website, is aimed at amputees, those with different-sized feet, and others who may have felt excluded by the shoe industry.It’s part of Zappos Adaptive, an initiative started in 2017 to “connect people with products that makes getting dressed easier for everyone” according to the company. It includes products with easy-on features like zippers and velcro.Zappos was acquired by Amazon in 2009. 556
