A gunman killed three black people in a racially motivated attack then killed himself in Jacksonville, Florida, the city's sheriff said. The man, described as white and in his early 20s, entered a Dollar General store and opened fire, triggering a standoff with police. Sheriff T K Waters said two men and a woman were killed by the gunman, who wore body armour and left manifestos. Mayor Donna Deegan said it was a "hate-filled crime" driven by racist hatred. The sheriff said the shooter - who has not yet been officially named - carried a lightweight semi-automatic rifle and a handgun. He is believed to have acted alone and allegedly wanted to kill himself. He lived in Jacksonville's Clay County with his parents and left several messages about his intentions, Sheriff Waters said, including one to his parents and another to the media. The sheriff added that at least one of the guns had a swastika drawn on it.

How do spacecraft slow down? Rigid heat shields and retropropulsion have been the favorites of engineers for years. Now NASA is testing a new inflatable heat shield technology that could allow us to carry even larger payloads to worlds with atmospheres Launching on Nov. 1 aboard a United Launch Alliance Atlas V rocket along with NOAA’s JPSS-2 mission, the Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID, will demonstrate the heat shield’s ability to slow down and survive atmospheric entry Producers: Scott Bednar, Jessica Wilde Editor: Daniel Salazar Credit: NASA #NASA #Technology #Spacecraft

NASA’s Perseverance Mars rover is filling sample tubes with rocky material on the Red Planet as the agency works on the next steps to get them safely back to Earth. The Mars Sample Return campaign would bring samples collected by the Perseverance rover to Earth for detailed study. The campaign involves an international interplanetary relay team, including the European Space Agency (ESA). These samples could answer a key question: did life ever exist on Mars? Aaron Yazzie, who works on the Mars Sample Return campaign, explains the work being done at NASA’s Jet Propulsion Laboratory to ensure the safe return of the sample tubes.
