The LIGO-Virgo-KAGRA Collaboration unveiled several studies that shed important new light on the nature of gravitational waves-ripples in time and space produced by merging black holes and/or neutron stars. They include a "census" of gravitational wave events to date and a new catalog of results from the second half of its third observing run (O3b), describing 90 gravitational wave events observ NASA selects new mission to study storms, impacts on climate models

NASA has selected a new Earth science mission that will study the behavior of tropical storms and thunderstorms, including their impacts on weather and climate models. The mission will be a collection of three SmallSats, flying in tight coordination, called Investigation of Convective Updrafts (INCUS), and is expected to launch in 2027 as part of NASA's Earth Venture Program.
NASA selected Radiocarbon is key to understanding Earth's past

Radiocarbon records are critical to understanding the history of Earth's climate, magnetic field, and the Sun's activity, say researchers.
In an article published in the journal Science, scientists have highlighted how recent advances in our knowledge of past radiocarbon levels are improving our understanding of climate processes, solar activity, geophysics and the carbon cycle.

The recent increase of Sphagnum mosses over wet aapa mires can be detected from Landsat satellite data. Aapa mire is a northern peatland complex type characterized by wet, sparsely vegetated fens in the central part, while margins are dominated by peat mosses.
In recent years, the increase of Sphagnum mosses has been observed in many parts of Finland and some regions of North America. The NASA, USGS release first Landsat 9 images

Landsat 9, a joint mission between NASA and the U.S. Geological Survey (USGS) that launched Sept. 27, 2021, has collected its first light images of Earth.
The images, all acquired Oct. 31, are available online. They provide a preview of how the mission will help people manage vital natural resources and understand the impacts of climate change, adding to Landsat's unparalleled data record 'Sad sight': Astronaut reports back on Earth's climate disaster

Earth needs a ‘mission control’ to manage climate data collected from space
Monday, 08 November 2021 20:30 Write a comment
Much of the critical data used to track climate change and its impact on Earth is collected by satellites in space. But all that data needs to be better analyzed in order to better cope with the climate crisis, said Ellen Stofan, undersecretary for science and research at the Smithsonian Institution.
Four station astronauts catch ride with SpaceX back home
Monday, 08 November 2021 19:25 Write a comment
Four astronauts in orbit since spring headed back to Earth on Monday, aiming for a late night splashdown off the Florida coast.
The undocking of their SpaceX capsule from the International Space Station also paved the way for a launch of their four replacements as early as Wednesday night.
The newcomers were scheduled to launch first, but NASA switched the order because of bad weather and an astronaut's undisclosed medical condition. The welcoming duties will now fall to the lone American and two Russians left behind at the space station.
NASA astronauts Shane Kimbrough and Megan McArthur, Japan's Akihiko Hoshide and France's Thomas Pesquet should have been back Monday morning, but high wind in the recovery zone delayed their homecoming.

Astronaut crew prepares to return to Earth

Four astronauts were preparing to leave the International Space Station and head back to Earth on Monday after spending six busy months aboard the orbital outpost.
The Crew-2 mission, which includes two Americans, a Frenchman and one Japanese astronaut, have been living and working on the space lab since April 24, carrying out hundreds of experiments and upgrading the station's solar panels.
They are now set to board their SpaceX Dragon capsule named "Endeavour" and undock from the ISS at 2:05 pm US Eastern Time (1905 GMT) before splashing down off the coast of Florida at 10:33 pm (0333 GMT Tuesday). NASA will provide a livestream.
"Last minute packing, getting ready to depart ISS," tweeted Japan's Akihiko Hoshide.
"It has been a fun 6+ months—pleasure and honor working with ALL the incredible people from around the world, both on & off the planet."
Their activities have included documenting the planet's surface to record human-caused changes and natural events, growing chile peppers and studying worms to better understand human health changes in space.
Crew-2's departure was delayed a day by high winds.

ESA astronaut Thomas Pesquet is sharing scenes from life on board the International Space Station during his second mission “Alpha”. Here he gives a quick tour of the SpaceX Cargo Dragon Endeavour that brought him to the Space Station together with JAXA astronaut Aki Hoshide and NASA astronauts Shane Kimbrough and Megan McArthur. The same astronauts, Crew-2, will use the spacecraft to return home after undocking with the Station and fly to Earth for a splashdown off the coast of Florida, USA.
Over 200 experiments are planned during Thomas’ time in space, with 40 European ones and 12
