In a study published in the Journal of Cosmology and Astroparticle Physics, researchers at the University of Toronto reveal a theoretical breakthrough that may explain both the nature of invisible dark matter and the large-scale structure of the universe known as the cosmic web. The result establishes a new link between these two longstanding problems in astronomy, opening new possibilities for It easier ever view Mars landscapes in high resolution

There is a huge difference between looking at a photo of the Grand Canyon and seeing it in person. If you want to look at another planet's landscape, seeing it in person is not an option. That's why a team at the U.S. Geological Survey used supercomputers and cloud computing to process and release a treasure trove of ready-to-use Mars data: more than 4,800 digital terrain models, known as DTMs, Scientists shed light on the unusual origin of a familiar meteor shower

Each winter, the Geminid meteors light up the sky as they race past Earth, producing one of the most intense meteor showers in the night sky. Now, NASA's Parker Solar Probe mission is providing new evidence that a violent, catastrophic event created the Geminids.
Most meteor showers come from comets, which are made of ice and dust. When a comet travels close to the Sun, the ice evaporates A Geologist in a Rock Shop: Sols 3859-3860

It appears that Curiosity's recent traverse has turned a new leaf as this is the second successful drive after lots of slipping and sliding. The new workspace is full of goodies for us to target and fill our 2-sol plan with, in addition to new perspectives of features off in the distance. The rover passed the "Slip Risk Assessment Process" (SRAP) which means we can unstow the arm and use its ins DESI data sheds more light on 3D map of cosmos, study of universe

Dr. Mustapha Ishak-Boushaki, a theoretical astrophysicist at The University of Texas at Dallas, has spent his career seeking answers to some of the universe's greatest mysteries, including why the expansion of the universe seems to be accelerating and whether gravity behaves differently beyond our closest cosmic neighbors.
To study these and other questions, a large collaboration of scient Gemini North detects multiple heavier elements in atmosphere of hot Exoplanet

Astronomers using the Gemini North telescope, one half of the International Gemini Observatory operated by NSF's NOIRLab, have detected multiple rock-forming elements in the atmosphere of a Jupiter-sized exoplanet, WASP-76b. The planet is so perilously close to its host star that rock-forming elements - such as magnesium, calcium, and nickel - become vaporized and dispersed throughout its scorch Paving the way for a new era in space: ESA's ambitions at the Paris Air Show 2023

The Paris Air Show, one the oldest and largest aerospace events in the world, is back at Le Bourget from 19 to 25 June. ESA is taking part to showcase the Agency’s latest accomplishments, highlight upcoming endeavours and present what’s next in the European Space Agency’s long-term ambitions. There will also be an intense week-long programme of lively panels and sessions, some of which will be livestreamed on ESA Web TV and Twitter. So, whether you are in Paris or not, you can join us at Le Bourget by watching our broadcasts!
More countries encouraged to commit to halt destructive ASAT tests

Despite an overwhelming vote of support by the United Nations General Assembly six months ago, advocates of a moratorium on one type of anti-satellite tests say they are still working to get more countries to adopt it.

Astronauts will be tracking dust into the Lunar Gateway. Is this a problem?
Wednesday, 14 June 2023 17:27 Write a comment
Lunar regolith (aka. moondust) is a major hazard for missions heading to the moon. It's everywhere on the surface—5 to 10 meters (~16.5 to 33 feet) in depth in some places—not to mention jagged and sticky. During the Apollo missions, astronauts learned how this dust adhered to everything, including their spacesuits. Worse, it would get tracked back into their lunar modules (LMs), where it stuck to surfaces and played havoc with electronics and mechanical equipment, and even led to long-term respiratory problems.
This is a major concern for the Artemis Program, which aims to establish a "sustained program of lunar exploration and development." One of the key elements of this program is the Lunar Gateway, a lunar habitat that will orbit the moon for a planned 15 years and facilitate long-term missions to the surface.

NASA laser communications terminal delivered for Artemis II moon mission
Wednesday, 14 June 2023 14:18 Write a comment
The laser communications system for NASA's Artemis II mission arrived at NASA's Kennedy Space Center in Florida for integration with the Orion spacecraft, which will carry astronauts around the Moon for the first time since the Apollo missions.
On November 16, 2022, NASA launched the Artemis I mission, an uncrewed flight test that took the human-rated Orion spacecraft farther into space than any before. The next mission, Artemis II, will test all of Orion's systems needed for crewed spaceflight and set the stage for future missions to the lunar surface. The Artemis II mission will also test new and enhanced technologies including laser communication capabilities.
Orion's laser communications terminal is known as the Orion Artemis II Optical Communications System, or O2O.
Laser communications systems, like O2O, provide missions with increased data rates, meaning they can send and receive more information in a single transmission compared to traditional radio wave systems, which most NASA missions use today.
Foldable phased-array transmitters developed for lightweight, smaller, and cost-efficient satellites
Wednesday, 14 June 2023 14:10 Write a comment
A newly designed foldable phased-array transmitter can help make satellites lightweight, smaller, and cost-efficient to launch, report scientists at Tokyo Tech. The transmitter is made of stacked layers of liquid crystal polymer and incorporates flexible creases, which provide flexibility and deployability. The new design could make research and implementation of space technologies more accessible to private companies and startups.
There has been a recent shift in the space industry towards what is now called the "new-space era." The term refers to how space is no longer dominated exclusively by government agencies such as NASA but has instead become a playground for many private companies and startups interested in exploring and deploying space technologies.
