Researchers at Imperial College London and Google DeepMind have harnessed neural networks, a form of AI modeled after the human brain, to address one of quantum chemistry's most challenging problems: modeling the states of molecules. Their findings could pave the way for new approaches to designing materials and chemical processes via computer simulations, potentially streamlining experimental e New Horizons Offers Precise Measurements of Cosmic Light in the Universe

Astronomers have achieved a significant milestone in understanding the darkness of deep space, thanks to NASA's New Horizons spacecraft. This mission has enabled the most accurate and direct measurements to date of the total amount of light generated by the universe.

Figuring out the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles in physics. New results from the world's most sensitive dark matter detector, LUX-ZEPLIN (LZ), have narrowed down possibilities for one of the leading dark matter candidates: weakly interacting massive particles, or WIMPs.
LZ, led by the Department Solar Orbiter Identifies Magnetic Mechanism Behind Solar Wind Acceleration

ESA's Solar Orbiter spacecraft has delivered vital data that sheds light on the longstanding mystery of the energy source responsible for heating and accelerating the solar wind. In collaboration with NASA's Parker Solar Probe, the Solar Orbiter has unveiled that significant fluctuations in the Sun's magnetic field are the driving force behind this process.

Astrobotic's Peregrine Mission One (PM1), launched on January 8, 2024, aboard United Launch Alliance's Vulcan rocket, aimed to make history by landing on the Moon. However, a significant anomaly during the mission's early stages prevented the lander from achieving its primary objective. Despite this setback, the mission provided valuable insights and data that will inform future lunar endeavors. NASA cuts 2 from next SpaceX flight to make room for astronauts stuck at space station

NASA on Friday cut two astronauts from the next crew to make room on the return trip for the two stuck at the International Space Station.
NASA's Nick Hague and Russian Aleksandr Gorbunov will launch in September aboard a SpaceX rocket for the orbiting laboratory. The duo will return with Suni Williams and Butch Wilmore in February. NASA decided it's too risky for Williams and Wilmore to fly home in their Boeing Starliner capsule, marred by thruster troubles and helium leaks.

Solar sails are an exciting way to travel through the solar system because they get their propulsion from the sun. NASA has developed several solar sails, and their newest, the Advanced Composite Solar Sail System (or ACS3), launched a few months ago into low Earth orbit.

NZ's Space Agency is both regulator and developer of the aerospace industry—that's a point of tension, say researchers
Friday, 30 August 2024 13:50 Write a comment
Like the global space industry, which aims to reach a value of US$1.8 trillion by 2035, New Zealand's aerospace sector is growing rapidly.
But as our latest research shows, it is falling short on addressing urgent sustainability issues because of a perception this would incur short-term costs and slow growth.
Many countries are prioritizing the development of national space strategies. Usually, these include plans to increase access to venture capital, grow a specialist workforce and develop flexible regulations and sovereign defense capabilities.
But sustainability leadership in space is crucial, given rising concerns over space debris, and emerging issues such as ozone depletion from rocket launches and the accumulation of alumina and soot particles in Earth's atmosphere as re-entering objects burn up.
The politics of growth
New Zealand's aerospace regulatory system was catalyzed by Rocket Lab U.S.'s commercial decision to launch rockets from a spaceport on the Māhia peninsula.
This was followed by the establishment of New Zealand's Space Agency. This small unit of the Ministry of Business, Innovation and Employment (MBIE) regulates launch payloads and fosters business development by facilitating access to funding for commercial ventures and scientific research.
Blue Origin completes latest space tourism flight

Blue Origin flew its latest group of six thrill-seekers to the edge of space and back again Thursday, including the youngest-ever woman to complete the feat.
Mission NS-26 marked the eighth human spaceflight for the company, founded by Jeff Bezos, as it presses ahead in the emerging suborbital tourism market.
Karsen Kitchen, a 21-year-old senior at the University of North Carolina at Cha What type of excavator is most suitable for asteroids?
Friday, 30 August 2024 13:22 Write a comment
Digging in the ground is so commonplace on Earth that we hardly ever think of it as hard. But doing so in space is an entirely different proposition. On some larger worlds, like the moon or Mars, it would be broadly similar to how digging is done on Earth. But their "milligravity" would make the digging experience quite different on the millions of asteroids in our solar system.
Given the potential economic impact of asteroid mining, there have been plenty of suggested methods on how to dig on an asteroid, and a team from the University of Arizona has published the latest in a series of papers about using a customized bucket wheel to do so.
Bucket wheel designs seem to be gaining popularity in space mining more generally lately. NASA's ISRU Pilot Excavator (IPEx) uses a similar design and has been advanced to Technology Readiness Level 5, according to its latest yearly report.

Cluster’s Salsa satellite primed to reenter and break up

On 8 September 2024, Salsa (Cluster 2), one of four satellites that make up ESA’s Cluster mission, will reenter Earth’s atmosphere over the South Pacific Ocean Uninhabited Area.
Salsa’s reentry marks the end of the historic Cluster mission, over 24 years after the quartet was sent into space to measure Earth’s magnetic environment. Though the remaining three satellites will also stop making scientific observations, discoveries using existing mission data are expected for years to come.
This ‘targeted reentry’ is the first of its kind, and goes well beyond international standards. ESA is committed to ensuring the long-term sustainability of space activities by mitigating the creation of space debris wherever possible
University of Florida professor to fly Blue Origin New Shepard on mission for NASA

University of Florida horticulture science professor Rob Ferl is going where some men have gone before, including William Shatner and Jeff Bezos, but he's bringing along some experimental plant life for NASA.
Ferl, a researcher within UF's Institute of Food and Agricultural Sciences, is also the director of UF's new Astraeus Space Institute. He is joining five other people on the launch of Blue Origin's suborbital New Shepard rocket today for what will be its eighth human spaceflight. Dubbed NS-26, the capsule is set for liftoff as early as 9:00 a.m. EDT from Blue Origin's West Texas launch facility.
Along for the ride will be a species of plant called Arabidopsis thaliana. Ferl will be looking at how its genes adapt on the way to space.
"Space is a challenging environment, one that we're not evolutionarily designed for," he said during a phone interview from the launch site. "And so the question is, what tools can we bring to bear to understand how much adaptation, how much physiological change has to occur in order to survive and thrive in space.
