Up to half of Earth"s water may come from solar wind and space dust
Water is vital for life on Earth, and some experts say we should all drink around two liters every day as part of a healthy lifestyle. But beyond the tap, where does our water come from?.....»»
NASA"s Deep Space Optical Communications demonstration transmits data over 140 million miles
Riding aboard NASA's Psyche spacecraft, the agency's Deep Space Optical Communications technology demonstration continues to break records. While the asteroid-bound spacecraft doesn't rely on optical communications to send data, the new technology ha.....»»
Drinking water in low-income communities is more likely to be contaminated by "forever chemicals," research finds
PFAS, or forever chemicals, are widespread and more likely to be found in public water systems serving low-income communities and communities of color in New Jersey, according to new research from Northeastern University......»»
Managing meandering waterways in a changing world
Just as water moves through a river, rivers themselves move across the landscape. They carve valleys and canyons, create floodplains and deltas, and transport sediment from the uplands to the ocean......»»
Scientists combine a spatially distributed sediment delivery model and biogeochemical model to estimate fluxes by water
Water erosion is the most active process controlling soil formation and evolution, which can affect the redistribution of carbon between terrestrial, aquatic, and atmospheric ecosystems. Erosion-induced organic carbon dynamic process should not be mi.....»»
Psyche spacecraft sends data back to Earth using lasers for the first time
NASA's experimental laser communication system, riding along with the Psyche spacecraft, has transmitted Psyche data from over 140 million miles away......»»
Solar geoengineering to cool the planet: Is it worth the risks?
When I first wrote about geoengineering in 2012 , it was considered far-fetched at best, and crazy by most. But 12 years later, while there is still controversy and considerable resistance to deploying it, respectable scientists and institutions are.....»»
China launches 3-member crew to its space station as it seeks to put astronauts on the moon by 2030
China launched a three-member crew to its orbiting space station on Thursday as part of its ambitious program that aims to put astronauts on the moon by 2030......»»
Cocaine is an emerging contaminant of concern in the Bay of Santos (Brazil), says researcher
In addition to already known pollutants, the Bay of Santos—a city in the state of São Paulo (Brazil) that is home to the largest seaport in Latin America—has been affected by an emerging contaminant that is now present not only in the water but.....»»
The Mars Sample Return mission has a shaky future, and NASA is calling on private companies for backup
A critical NASA mission in the search for life beyond Earth, Mars Sample Return, is in trouble. Its budget has ballooned from US$5 billion to over $11 billion, and the sample return date may slip from the end of this decade to 2040......»»
Warming Arctic reduces dust levels in parts of the planet, study finds
Climate change is a global phenomenon, but its impacts are felt at a very local level. Take, for example, dust. Dust can have a huge impact on local air quality, food security, energy supply and public health. Yet, little is known about how global cl.....»»
A better way to predict Arctic riverbank erosion
Arctic riverbanks are typically resilient, thanks to the power of permafrost. This permanently frozen soil locks in sediment, leading to low erosion rates. But as Arctic river water warms due to climate change, some researchers worry that riverbanks.....»»
The guardian angels of the source of the Seine
The river Seine, the centerpiece of the Paris Olympics opening ceremony in July, starts with a few drops of water in a mossy grotto deep in the woods of central France......»»

China’s space station was hit by space junk
China's space agency says it has successfully repaired damage to its space station after it was struck by space debris......»»
Apple Watch X: The latest on Apple’s plans for a major design refresh
Apple is believed to be working on “the biggest overhaul yet” to the Apple Watch’s design. A new rumor today indicates that the next-generation Apple Watch could include a design change that frees up more space inside for other components – .....»»
See incredible time lapses of two of space’s most famous objects
Two striking timelapses from NASA's Chandra X-ray Observatory show how two famous objects have changed over the last two decades......»»
Pushing the limits of sub-kilowatt electric propulsion technology for space mission concepts
NASA has developed an advanced propulsion technology to facilitate future planetary exploration missions using small spacecraft. Not only will this technology enable new types of planetary science missions, one of NASA's commercial partners is alread.....»»
Shoreline model predicts long-term future of storm protection and sea-level rise
Researchers in North Carolina have created a simulation model to analyze how coastal management activities meant to protect barrier islands from sea-level rise can disrupt the natural processes that are keeping barrier islands above water......»»
Africa"s megacities threatened by heat, floods, disease—action needed to start greening, adapt to climate change
Cities cover just 3% of the planet. But they emit 78% of all global greenhouse gas emissions, absorb 80% of final global energy (what consumers use) and consume 60% of clean drinking water......»»
Mantle heat may have boosted Earth"s crust 3 billion years ago
Little is known about the nature and evolution of Earth's continental crust before a few billion years ago because cratons, or stable swaths of the lithosphere more than 2–3 billion years old, are relatively rare......»»
