Helicopter scouts ridge area for Perseverance
Ask any space explorer, and they'll have a favorite photo or two from their mission. For Kevin Hand, a scientist at NASA's Jet Propulsion Laboratory in Southern California and co-lead of the Perseverance rover's first science campaign, his latest favorite is a 3D image of low-lying wrinkles in the surface of Jezero Crater. The science team calls this area "Raised Ridges." NASA's Ingenuity Mars H
Satellites reveal how forests increase cloud and cool climate
Forests are not only key to moderating our climate by sequestering atmospheric carbon, but they also create a cooling effect by increasing low-level cloud. A first global assessment using satellite observations has shown that for two-thirds of the world, afforestation increases low-level cloud cover, with the effect being strongest over evergreen needleleaf forest.
What it takes to become Australia's first woman astronaut
I'm currently training to become Australia's first woman astronaut. I expect to fly my first suborbital mission sometime in 2023 as a payload specialist on a commercial mission. In other words, I'll be one of few certified crew members who can handle specialized scientific equipment aboard a suborbital spacecraft.
Once we're up there, my team and I expect to conduct research on Earth's atmosphere. It's an opportunity I consider out of this world. But it has taken a lot of effort for this dream to be realized.
My path to PoSSUM
As a female STEM and legal professional, my past jobs included working as a research scientist in mining and metals for BHP-Billiton, Rio Tinto and the Australian Nuclear Science and Technology Organisation (ANSTO)—but I always loved space.
Summer stargazing treat as Perseid meteor shower reaches its peak
The Perseid meteor shower reaches its peak on the night of 11–12 August, giving skywatchers a potentially impressive summer treat. The meteors are best viewed from the northern hemisphere, and in ideal conditions with no clouds observers could see up to 50 an hour.
Meteors are the result of small particles entering the Earth's atmosphere at high speed, typically around 60 km per second.
NASA identifies likely locations of the early molten moon's deep secrets
Boeing Starliner launch delayed indefinitely
Boeing's Starliner won't launch Wednesday as had been planned following problems with its propulsion system that prevented a key uncrewed test flight to the international space station a day earlier—and it's not clear when the troubled spaceship will fly next.
The aerospace giant said in a statement that valves in Starliner's engine were in "unexpected" positions, forcing the mission team to halt the countdown.
NASA added that engineering teams have ruled out several potential causes, including a software glitch, but need more time to understand the issue.
"We're going to let the data lead our work," said John Vollmer, vice president and program manager of Boeing's Commercial Crew Program.
Impact of space station spin requires study, official says
Europe’s Spaceport gains new radar
A new additional radar called Amazonie-I installed at Pariacabo, a high point in Kourou, French Guiana, was tested during the recent Ariane 5 launch from Europe’s Spaceport.
No 'eureka moment': the evolution of climate science
What if Earth's atmosphere was infused with extra carbon dioxide, mused amateur scientist Eunice Foote in an 1856 research paper that concluded the gas was very good at absorbing heat. "An atmosphere of that gas would give to our earth a high temperature," she wrote in the study, published in the American Journal of Science and Arts and then swiftly forgotten. The American scientist a
Decline in CO2 cooled earth's climate over 30 million years ago, scientists find
New research led by the University of Bristol demonstrates that a decline in the concentration of atmospheric CO2 played a major role in driving Earth's climate from a warm greenhouse into a cold icehouse world around 34 million years ago. This transition could be partly reversed in the next centuries due to the anthropogenic rise in CO2. Between 40 and 34 million years ago, Earth's climat
