Rocks show Mars once felt like Iceland
Write a comment
Once upon a time, seasons in Gale Crater probably felt something like those in Iceland. But nobody was there to bundle up more than 3 billion years ago.
The ancient Martian crater is the focus of a study by Rice University scientists comparing data from the Curiosity rover to places on Earth where similar geologic formations have experienced weathering in different climates.
3-D printing to pave the way for moon colonization
Write a comment
A research team from the Skoltech Center for Design, Manufacturing and Materials (CDMM) comprising 2nd year Ph.D. student Maxim Isachenkov, Senior Research Scientist Svyatoslav Chugunov, Professor Iskander Akhatov, and Professor Igor Shishkovsky has prepared an extensive review on the use of Additive Manufacturing (AM) technologies (also known as 3-D-printing) in crewed lunar exploration. Their paper published in the journal Acta Astronautica contains a comprehensive description of the geological composition of the lunar surface and the properties of lunar soil (lunar regolith) and its simulants, detailing their mineralogy, morphology, and chemical composition, in the light of their future use as feedstock for 3-D-printing on the moon surface.
The authors evaluated different 3-D-printing techniques presented in literature in terms of their suitability for in-situ manufacturing and maintainability, with focus on the adaptation of AM methods to low gravity, limited energy consumption, dimension and weight constraints of AM components delivered to the moon, scalability of AM technologies, low-gravity performance of 3-D-printing methods, and autonomy of AM applications.
Astronomers dissect the anatomy of planetary nebulae using Hubble images
Write a comment
Images of two iconic planetary nebulae taken by the Hubble Space Telescope are revealing new information about how they develop their dramatic features. Researchers from Rochester Institute of Technology and Green Bank Observatory presented new findings about the Butterfly Nebula (NGC 6302) and the Jewel Bug Nebula (NGC 7027) at the 237th meeting of the American Astronomical Society on Friday, J Autonomous driving on intelligent road at Europe's edge
Write a comment
An ESA-supported effort put an intelligent road up in Finnish Lapland through its paces, assessing its suitability for testing autonomous vehicles in some of Europe's most challenging driving conditions.
"If autonomous vehicles can drive well here, they can drive almost anywhere," says Sarang Thombre of the Finnish Geospatial Research Institute, managing the Arctic-PNT project.
"Our Lunar Surface Trash or Treasure?

Now that NASA is leading the development of the Artemis lunar habitation program that will send men and women to the Moon within the next few years, this may be a good time to preview at least one aspect of the environment that the astronauts will experience when they arrive, i. e., trash from Earth.

Astroscale reports that its End-of-Life Services by Astroscale-demonstration (ELSA-d) satellite has arrived at the Baikonur Cosmodrome in Kazakhstan, ready for anticipated launch on March 20, 2021. ELSA-d will launch on a Soyuz rocket operated by GK Launch Services.

The elusive axion particle is many times lighter than an electron, with properties that barely make an impression on ordinary matter. As such, the ghost-like particle is a leading contender as a component of dark matter - a hypothetical, invisible type of matter that is thought to make up 85 percent of the mass in the universe.

Iceland' Astronomers estimate Titan's largest sea is 1,000 feet deep
Write a comment
Far below the gaseous atmospheric shroud on Saturn's largest moon, Titan, lies Kraken Mare, a sea of liquid methane. Cornell astronomers have estimated that sea to be at least 1,000 feet deep near its center - enough room for a potential robotic submarine to explore.
After sifting through data from one of the final Titan flybys of the Cassini mission, the researchers detailed their finding
