Readying spacecraft to surf Venus" atmosphere
ESA's EnVision mission to Venus will perform optical, spectral and radar mapping of Earth's sister planet. But before getting down to work the van-sized spacecraft needs to "aerobrake"—lowering its orbit with thousands of passages through the plane.....»»
A new electrochemical approach could reduce ocean acidity and remove carbon in the process
In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The technologies for reducing ou.....»»
From the coast to the deep sea, changing oxygen levels affect marine life in different ways
Earth's atmosphere maintains a constant level of oxygen, whether it is a wintry, rainy day or hot summer. Across the ocean, oxygen concentrations vary enormously between different places and over time. Sometimes oxygen levels change within the course.....»»
Astronauts take major step toward Starliner’s first crewed flight
After numerous delays across many years, NASA is closer than ever to launching its first astronauts aboard the Boeing-made CST-100 Starliner spacecraft......»»
Voyager 1 spacecraft is still alive and sending signals to Earth
NASA has announced that it is back in contact with Voyager 1, around five months after communications with the spacecraft were disrupted......»»
Climate impacts set to cut 2050 global GDP by nearly a fifth
Climate change caused by CO2 emissions already in the atmosphere will shrink global GDP in 2050 by about $38 trillion, or almost a fifth, no matter how aggressively humanity cuts carbon pollution, researchers said Wednesday......»»
See a flyby of Io, a hellish moon with lakes of lava and an otherworldly mountain
NASA's Juno spacecraft has been investigating Jupiter's moon Io, the most volcanically active body in the solar system, and has observed some dramatic features......»»
The Italian central Apennines are a source of CO₂, study finds
Tectonically active mountains play an important role in the natural CO2 regulation of the atmosphere. Competing processes take place here: At Earth's surface, erosion drives weathering processes that absorb or release CO2, depending on the type of ro.....»»
NASA may alter Artemis III to have Starship and Orion dock in low-Earth orbit
If it were to happen, a revised Artemis III mission could echo Apollo 9. Enlarge / This image taken by NASA's Orion spacecraft shows its view just before the vehicle flew behind the Moon in 2022. (credit: NASA) Although.....»»
Using deep learning to image the Earth"s planetary boundary layer
Although the troposphere is often thought of as the closest layer of the atmosphere to the Earth's surface, the planetary boundary layer (PBL)—the lowest layer of the troposphere—is actually the part that most significantly influences weather nea.....»»
All the pieces are in place for the first crew flight of Boeing’s Starliner
“This is a test flight, and a complicated one at that." Enlarge / Technicians inside United Launch Alliance's Vertical Integration Facility connect Boeing's Starliner spacecraft to the top of its Atlas V rocket Tuesday. (credit.....»»
The Rise of the Carbon Farmer
Farmers around the world are reigniting the less intensive agricultural practices of yesteryear—to improve soil health, raise yields, and trap carbon in the atmosphere back down in the soil......»»
NASA"s Dragonfly rotorcraft mission to Saturn"s moon Titan confirmed
NASA has confirmed its Dragonfly rotorcraft mission to Saturn's organic-rich moon Titan. The decision allows the mission to progress to the completion of the final design, followed by the construction and testing of the entire spacecraft and science.....»»
NASA observations find what helps heat roots of "moss" on sun
Did you know the sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere "moss." This moss, which was first identified in 1999 by NASA's TRACE mi.....»»
Starliner spacecraft just took a major step toward first crewed flight
Boeing has stacked the Starliner spacecraft atop an Atlas V rocket ahead of the capsule's first crewed flight to orbit next month......»»
Surf clams off the coast of Virginia reappear and rebound
The Atlantic surf clam, an economically valuable species that is the main ingredient in clam chowder and fried clam strips, has returned to Virginia waters in a big way, reversing a die-off that started more than two decades ago......»»
Formation-flying spacecraft could probe the solar system for new physics
It's an exciting time for the fields of astronomy, astrophysics, and cosmology. Thanks to cutting-edge observatories, instruments, and new techniques, scientists are getting closer to experimentally verifying theories that remain largely untested. Th.....»»
Video: Is there a quick fix for ocean acidification?
Acidification is threatening the ocean's ability to pull carbon dioxide out of our atmosphere, so scientists and startups are looking to ocean-sized antacids to raise its pH......»»
NASA discovered bacteria that wouldn"t die. Now it"s boosting sunscreen.
While disinfecting spacecraft headed for Mars, NASA found a stubborn type of bacteria that was tough to clean but great at withstanding UV radiation. Many people associate NASA with exploring new worlds in space, but few know it's also finding.....»»
This is the new spaceship that will take humans back to the moon
The completed Orion spacecraft, built by NASA and ESA, is seen fully stacked in a newly released photo. This craft will fly around the moon on the Artemis II mission. Next year, NASA will blast astronauts back to the moon. This is their 21st-ce.....»»
Watch NASA begin testing its Orion capsule for lunar flyby
NASA has started testing the Orion spacecraft that will take astronauts on a voyage around the moon in the Artemis II mission scheduled for 2025......»»
