NASA weighs SpaceX rescue for stranded Boeing Starliner crew
Write a comment
What was meant to be a weeklong trip to the International Space Station (ISS) for the first NASA astronauts to fly with Boeing could extend to eight months, with the agency considering bringing them home on a SpaceX spaceship.
A final decision on whether to persist with Boeing's troubled Starliner—which experienced worrying propulsion issues as it flew up to the orbital platform in June—is expected later this month, officials said Wednesday in a call with reporters.
Detailed planning is already underway with Boeing's rival SpaceX, owned by Elon Musk, to potentially launch their scheduled Crew-9 mission on September 24 with just two astronauts rather than the usual four.

Detecting nitrogen dioxide emissions from power plants using Sentinel-2 satellites
Write a comment
Paris, France (SPX) Aug 06, 2024
Atmospheric nitrogen dioxide (NO2) is a hazardous pollutant with profound effects on air quality, climate, and the biosphere. While satellites have been mapping NO2 concentrations since the 1990s, their resolutions have generally been too coarse to identify individual sources such as power plants.
A recent study has made significant strides in air pollution monitoring by using imagery from

Sydney, Australia (SPX) Aug 05, 2024
This study, led by Dr. Wei Wei, PhD student Lin-Hui Dong, and Prof. Fang Huang at the University of Science and Technology of China, investigates the removal of excess barium and sulfide from seawater and its impact on marine habitability during the Cambrian Explosion.
Lin-Hui Dong analyzed excess barium contents (Baexcess) and isotope compositions (d138Baexcess) at the State Key Laborator

New Fossil Discovery Sheds Light on Mollusc Evolution
Write a comment
London, UK (SPX) Aug 02, 2024
A team of researchers, including scientists from the University of Oxford, has uncovered a new species of mollusc dating back 500 million years. Named Shishania aculeata, this fossil reveals that the earliest molluscs were flat, shell-less slugs protected by spiny armor. These findings are published in the journal Science.
The discovery comes from well-preserved fossils found in eastern Yu

Early Sea Level Changes Influenced Evolution of Ancient Life, Study Shows

London, UK (SPX) Aug 05, 2024
A newly developed timeline of early animal fossils reveals a link between sea levels, changes in marine oxygen, and the appearance of the earliest ancestors of present-day animals.
The study reveals clues into the forces that drove the evolution of the earliest organisms, from which all major animal groups descended.
