An international team of astronomers has carried out what is believed to be the largest ever cosmological computer simulation, tracking not only dark but also ordinary matter (such as planets, stars and galaxies), giving us a glimpse into how our Universe may have evolved. The FLAMINGO simulations calculate the evolution of all components of the universe - ordinary matter, dark matter, and dark Dragonfly tunnel visions

With its dense atmosphere and low gravity, Saturn's moon Titan is a great place to fly.
But well before NASA's Dragonfly rotorcraft lander soars through Titan's skies, researchers on Earth - led by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland - are making sure their designs and models for the nuclear-powered, car-sized drone will work in a truly unique environment CRS-29 mission flies research to the Space Station

The 29th SpaceX commercial resupply services (CRS) mission for NASA carries scientific experiments and technology demonstrations, including studies of enhanced optical communications and measurement of atmospheric waves. The uncrewed SpaceX Dragon spacecraft is scheduled to launch to the International Space Station from the agency's Kennedy Space Center in Florida no earlier than Nov. 5.

Texas A and M University is joining a multi-university team on a major research project to track objects orbiting the moon. The Air Force Research Laboratory is awarding up to $5 million over five years for the Space University Research Initiative (SURI).
"The SURI is an outstanding initiative to train our next-generation workforce. We look forward to carrying out creative research aimed a UArizona researchers probe how a piece of the moon became a near-Earth asteroid

In 2021, a team of University of Arizona astronomers suggested that a recently discovered near-Earth asteroid, Kamo`oalewa, could be a chunk of the moon. Two years after the striking discovery, another UArizona research group has found that a rare pathway could have enabled this to happen.

The dry, wind-swept summits of volcanoes in the Puna de Atacama of Chile and Argentina are the closest thing on Earth to the surface of Mars due to their thin atmosphere and freezing temperatures. At their extreme elevations of more than 6,000 meters above sea level, experts had concluded that mammalian life simply wasn't possible.

By analyzing tiny lunar crystals gathered by Apollo 17 astronauts in 1972, researchers recalculated the age of the Earth's Moon. Although previous assessments estimated the Moon as 4.425 billion years old, the new study discovered it is actually 4.46 billion years old - 40 million years older than previously thought.

Researchers at New Jersey Institute of Technology's Center for Solar-Terrestrial Research (NJIT-CSTR) have captured the Oct. 14 solar eclipse in a way never seen before - recording the first radio images of an annular eclipse's famous "ring of fire" effect.
The eclipse was partially visible to much of the continental U.S. for several hours that Saturday, though the full "ring of fire" effe French Space Days India 2023 celebrates Indo-French collaboration

A Russian satellite has shifted within 60 km of another spacecraft

When it comes to saber-rattling, few countries employ it as much as Russia does. During their ongoing invasion and occupation of Ukraine, the country's leadership has repeatedly threatened to use atomic weapons. But the threats don't stop there.
A private company called Slingshot Aerospace says Russia has maneuvered one of their Luch satellites uncomfortably close to Western spacecraft in GEO (geostationary orbit.)
And it's not the first time.
The satellite in question is named Luch (Olymp) 2 and its Norad ID is 55841. Russia launched it in March of 2023, and it's a successor to Luch (Olymp) Norad ID 40258. The naming conventions are a little confusing, but Luch 1 was a well-known interloper.
Two groups look at the economic viability of mining asteroids
Monday, 23 October 2023 14:02 Write a comment
Two teams of economists have conducted economic assessments of mining asteroids—one of them is a trio with one member each from the University of Tor Rome Vergata, the University of Maryland and Middlebury College. They looked at asteroid mining as part of the next logical step in monetizing space exploration.
The second group, with three members from the Colorado School of Mines and a fourth with the International Monetary Fund, focused more on the challenges that would have to be surmounted for industry to capitalize on assets that are currently free for the taking on asteroids. Both groups have published papers describing their efforts in the journal Proceedings of the National Academy of Sciences.
Prior research has shown that there are valuable materials on asteroids. This includes diamonds and perhaps other gems, but the truly valuable materials are more likely to be metals that are highly valued but in short supply here on Earth, such as cobalt, nickel and platinum. Such metals have seen a rise in value in recent years as they have been used in a host of modern technology products such as batteries, solar panels and windmill parts.
