Caribbean braces as Beryl strengthens to ‘extremely dangerous’ Category 4 hurricane

Caribbean braces as Beryl strengthens to ‘extremely dangerous’ Category 4 hurricane

Beryl, the first hurricane of the 2024 Atlantic season, strengthened into an “extremely dangerous” Category 4 storm Sunday as it threatened the southeast Caribbean with potentially life-threatening winds and storm surge, US trackers said.

The U.S. National Hurricane Center (NHC) warned residents that Beryl — currently churning in the Atlantic Ocean about 350 miles (565 kilometers) east of Barbados — was creating a “very dangerous situation” and to heed local government and emergency management instructions.

Beryl “is now an extremely dangerous Category 4 hurricane,” it said, noting that the storm’s eye is expected to move early on Monday across the Windward Islands, a cluster of islands including Martinique, Saint Lucia and Grenada, among others....

NASA vows to battle ‘organizational silence’ as problems arise amid Artemis delays

NASA vows to battle ‘organizational silence’ as problems arise amid Artemis delays

ORLANDO, Fla. — NASA was riding a high after the overall success of Artemis I when the uncrewed rocket made a test run to the moon and back in 2022, so the message remained full steam ahead to push for a crewed Artemis II flight in 2024 and the return of humans to the moon in 2025. But under the surface were issues, and the sheen of success hit reality, prompting NASA to delay Artemis’ first human spaceflight until no earlier than September 2025, and then pushing the moon landing until at least one year later. A big driver of that delay was a NASA-driven, lessons-learned initiative that is clo......
San Diego State University report calls Tijuana River contamination 'a public health crisis'

San Diego State University report calls Tijuana River contamination 'a public health crisis'

SAN DIEGO — A new report from researchers at San Diego State University, citing "untreated sewage, industrial waste, and urban run-off due to inadequate infrastructure and urbanization," calls the Tijuana River "a public health crisis" that imperils the good health of a wide range of people who live, recreate and work near the polluted waterway, particularly when wet weather causes floods to spread. In a white paper that is not itself peer-reviewed research, authors synthesize the multiple studies that have documented pollution over the years, pausing on a recent paper documenting that the thr......
Military hopes one day to move supplies, maybe troops, on SpaceX’s Starship

Military hopes one day to move supplies, maybe troops, on SpaceX’s Starship

ORLANDO, Fla. — While NASA is rooting for SpaceX to achieve Starship success so it can land humans on the moon, the U.S. military has plans of their own for the massive rocket that could include launches from Florida’s Space Coast. Elon Musk’s next-generation rocket currently in development at SpaceX’s southeast Texas facilities is gearing up for its third suborbital test flight as soon as this month after its first two ended in explosions last year. It’s part of the company’s long-term plans for a completely reusable spacecraft with more payload capacity into space than any other rocket ever.......
Scientists warn of current ‘tipping point’ in Atlantic Ocean; ‘significant’ effects on climate

Scientists warn of current ‘tipping point’ in Atlantic Ocean; ‘significant’ effects on climate

A critical system of Atlantic Ocean currents may be approaching collapse, which scientists warn will have a dangerous impact on our global climate. The Atlantic meridional overturning circulation (AMOC), which “effectively transports heat and salt through the global ocean,” has recently shown signs of trending toward a crucial “tipping point” according to a study published Friday in the journal Science Advances. Scientists have been warning of the potential collapse for decades, as the currents’ strength has been weakened by rising temperatures which affect the system’s balance of heat and sal......
NASA’s Jet Propulsion Lab to lay off hundreds amid Mars mission budget cuts

NASA’s Jet Propulsion Lab to lay off hundreds amid Mars mission budget cuts

NASA’s Jet Propulsion Laboratory announced it was laying off 530 on staff or about 8% of its workforce on Tuesday after expected congressional budget cuts kneecapped one of its biggest endeavors, the Mars Sample Return mission. The Pasadena, California, institution is one of NASA’s major science mission hubs, the home to the majority of Mars missions, including the Perseverance rover currently collecting soil and rock samples as part of that mission. JPL Director Laurie Leshin said fiscal wrangling in Washington has led to an expected budget for that mission of only $300 million, less than a t......
