Two other U.S. companies are aiming for moon landings by year’s end: Jeff Bezos’ Blue Origin and Astrobotic Technology. Astrobotic’s first lunar lander missed the moon altogether in 2024 and came crashing back through Earth’s atmosphere.For decades, governments competed to get to the moon. Only five countries have pulled off successful robotic lunar landings: Russia, the U.S., China, India and Japan. Of those, only the U.S. has landed people on the moon: 12 NASA astronauts from 1969 through 1972.

NASA expects to send four astronauts around the moon next year. That would be followed a year or more later by the first lunar landing by a crew in more than a half-century, with SpaceX’s Starship providing the lift from lunar orbit all the way down to the surface. China also has moon landing plans for its own astronauts by 2030.The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Science and Educational Media Group and the Robert Wood Johnson Foundation.

are considering a property tax increase to pay for school-based police officers.Barrow County Superintendent Dallas LeDuff told school board members Tuesday that the tax increase would be necessary because county government has informed the school district that it will no longer pay for sheriff’s deputies, local news outlets reported.

The school district and Barrow County Commission have been splitting the price of deputies assigned as school resource officers since 2017. That number was originally 12, rose to 16 in 2024, and then to 24 after the shooting. That would place at least two officers in the district’s high schools and at least one officer in every other school, although officials haven’t yet been able to hire 24 deputies.

County commissioners sent a letter to LeDuff last month saying county government will for now pay half only 12 salaries, and eventually stop paying any of the costs.Alrededor de la 1:05 de la madrugada, drones tipo Shahed impactaron en dos edificios de apartamentos en el distrito Slobidskyi de la ciudad, provocando incendios y destruyendo varios vehículos particulares.

LOS ANGELES (AP) — The Trump administration signaled Wednesday that it intends to cut off federal funding for a long-delayed California high-speed rail project plagued by multibillion-dollar, following the release of a scathing federal report that concluded there is “no viable path” to complete even a partial section of the line.
