Officials are looking for the suspect responsible for a deadly stabbing in Phoenix.Phoenix police responded to an alley near 15th and Missouri avenues at 11:30 a.m. on Thursday for a report of a stabbing. Officers were alerted to the incident after a passerby called 911 about a man stumbling in the roadway. When officers arrived on the scene they found 58-year-old Alfred Brown with multiple stab wounds. He told officers the suspect, a younger Hispanic male, was heavy set and wearing a white shirt. According to police, Brown was transported to the hospital where he died from his injuries.Brown was a known homeless man who stayed in the area. He was last seen in the area earlier in the day with a Hispanic male who matches the suspect description. 789
Once the fissures open and the hot stuff starts flowing, it's best to not fight nature."The flows cannot be stopped, but people have tried in the past," said Benjamin Andrews, director of the Global Volcanism Program at the Smithsonian Nation Museum of Natural History.Flows can and have been diverted, though. The most famous example, Andrews cites, was in 1973 when the Eldfell volcano exploded on Heimaey, a small island in Iceland. 443

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
One of the fiercest rivalries in sport -- the New York Yankees versus the Boston Red Sox -- is on the move and heading to London as Major League Baseball flies across the Atlantic to broaden its global reach.MLB announced Tuesday that the Yankees and Red Sox will play two regular-season games at the London Stadium -- which played host to the athletics and opening and closing ceremonies of the London 2012 Olympics -- on June 29 and 30, 2019.The Red Sox will be the home team for the two-game series, the first MLB games to be played in Europe.But it will not be the first time regular-season MLB matches will have been played outside the US, with ties already having been staged in Mexico, Japan, Puerto Rico and Australia.It has already been announced that Oakland and Seattle will play next season's opener at the Tokyo Dome on March 20-21.As part of the two-year deal another series will be played in London in 2020. The participating teams have yet to be announced.Baseball commissioner Robert Manfred described the plan as "our most significant endeavor in Europe," while Tony Clark, executive director of the players' association, MLBPA, said fans should expect intense competition."Some of the most talented and dynamic players in the world will be playing in these games," he said at a news conference in London."They are excited about the chance to meet new fans, and showcase the game they love. They are aware they'll be a part of history, but they also know these games count." 1500
