Rare Dust Particle From Ancient Extraterrestrial Meteorite Challenges Astrophysical Models

Posted by in categories: particle physics, space

In a groundbreaking discovery published in the prestigious Astrophysical Journal, scientists have identified a rare dust particle lodged within an ancient extraterrestrial meteorite, shedding new light on the origins of stars beyond our solar system.

Advanced Research Techniques

Led by Dr. Nicole Nevill of the Universities Space Research Association at LPI, during her Ph.D. studies at Curtin University, the research team meticulously analyzed the dust particle, delving into its atomic composition with unparalleled precision using atom probe tomography.

“Tube Map” for Space: Unlocking Planetary Paths With Knot Theory

Posted by in categories: computing, mapping, mathematics, space

A novel mathematical technique from the University of Surrey now simplifies space mission planning by mapping efficient routes, akin to a subway map, potentially revolutionizing travel to the Moon and beyond.

Just as sat-nav did away with the need to argue over the best route home, scientists from the University of Surrey have developed a new method to find the optimal routes for future space missions without the need to waste fuel.

The new method uses mathematics to reveal all possible routes from one orbit to another without guesswork or using enormous computer power.

NASA plasma propulsion project promises Mars in a flash

Posted by in categories: energy, space

As well as slashing travel time to neighboring planets, PPR promises to support the transport of much heavier spacecraft, which can benefit from shielding against galactic cosmic rays, allowing space travelers to spend longer periods outside Earth’s protective dome.

The latter will be the subject of the NASA Innovative Advanced Concepts (NIAC) study, which is focusing on a large, heavily shielded ship to transport humans and cargo to Mars for the development of a Martian base.

“The main topics included: assessing the neutronics of the system, designing the spacecraft, power system, and necessary subsystems, analyzing the magnetic nozzle capabilities, and determining trajectories and benefits of the PPR. Phase II will build upon these assessments and further the PPR concept,” NASA said.

Einstein Challenged: Exploring the “Cosmic Glitch” in Gravity

Posted by in categories: physics, space

Moving one step closer to understanding mysteries at the edge of the universe.

A group of researchers at the University of Waterloo and the University of British Columbia have discovered a potential “cosmic glitch” in the universe’s gravity, explaining its strange behavior on a cosmic scale.

For the last 100 years, physicists have relied upon Albert Einstein’s theory of “general relativity” to explain how gravity works throughout the universe. General relativity, proven accurate by countless tests and observations, suggests that gravity impacts not simply three physical dimensions but also a fourth dimension: time.

The Moon Turned Itself Inside Out, Scientists Confirm

Posted by in category: space

Small Bang Scientists seem to have figured out why the Moon is made up of such weird and heavy rocks: way back in the day, it turned itself inside out.

For decades now, scientists have pretty much agreed that the Moon formed from debris that flew off the young Earth when another planet smashed into it about 4.5 billion years. That cosmic wreckage “coalesced, cooled and solidified” to form the Moon as we know it today, researchers from the University of Arizona’s Lunar and Planetary Laboratory wrote in a press release — but what happened next is something of a “choose-your-own adventure,” as the scientists describe it.

In a new paper published in the journal Nature Geoscience, the LPL researchers found that the surprisingly high concentration of titanium found in Moon rocks, such as those brought back during the Apollo mission in the 1970s, could be the result of heavy minerals like ilmenite, which is rich in both titanium and iron, initially sinking to the core and then rising back up to the surface.
