    Sometimes a mission can be too successful. When NASA's DART spacecraft slammed into Dimorphos in 2022 as part of an asteroid redirection test, it altered the asteroids orbit, proving that kinetic impactors can be used to defend Earth from hazardous objects. Unfortunately, the impact also created a shower of boulders ...

    China's Tianwen-3 is poised to be the first sample-return mission to Mars. The science team now includes a group of astrobiologists from Hong Kong University (HKU), led by Professor Yiliang Li. In a recent paper, the team advised the China National Space Agency (CNSA) on landing site selection and how ...
  • 2025-07-10
    An international team of scientists led by the Harvard School of Engineering and Applied Sciences (SEAS) proposed a new method for living beyond Earth. Their experiment demonstrated how bioplastic structures can be grown using algae, which would be rugged enough to survive the hostile Martian environment.
  • 2025-07-10
    NASA's Curiosity Rover has been exploring Gale Crater and found that carbonate materials make up to 11% of rocks in the region. These are important because carbonates formed by pulling CO2 out of Mars's atmosphere. A new paper suggests that Mars once had a self-regulating climate system that created oases ...

    Tokyo, Japan (SPX) Jul 07, 2025 China has formally initiated its Tianwen-3 Mars Sample Return (MSR) mission, targeting a 2028 launch to collect and return Martian soil and rock for detailed study. Among the key contributors is Professor Yiliang LI, an astrobiologist at The University of Hong Kong (HKU), who leads ...

    London, UK (SPX) Jul 08, 2025 Ice commonly found in space is not entirely amorphous, as long believed, but instead contains nanoscale crystals, according to a new study by scientists at University College London (UCL) and the University of Cambridge. The findings revise long-held views about low-density amorphous ice, which forms ...

    The origin of life is one of the most fundamental and enduring questions of mankind and one of the three greatest Origin Questions in the natural sciences. Recently, China officially launched its Mars Sample Return (MSR) mission, Tianwen-3, marking a significant step forward in planetary exploration. The mission aims to ...

    New images from NASA's Curiosity Mars rover show the first close-up views of a region scientists had previously observed only from orbit. The images and data being collected are already raising new questions about how the Martian surface was changing billions of years ago.
  • 2025-06-23
    Researchers at the universities of Amsterdam and Utrecht have observed the formation of nanocavities in montmorillonite clay under exposure to gamma-aminobutyric acid, a molecule commonly found on meteorites. This hitherto unrecognized phenomenon could be relevant to the origin of life on Earth, by introducing 3D confined nano-environments in clay that ...

    Georgia Tech scientists have uncovered evidence that a mountain on the rim of Jezero Crater—where NASA's Perseverance Rover is currently collecting samples for possible return to Earth—is likely a volcano. Called Jezero Mons, it is nearly half the size of the crater itself and could add critical clues to the ...

    Astronomers have found a rare form of methanol, a type of alcohol, in a planet-forming disk, providing a critical step in understanding how life beyond Earth may form. This result reveals vital details about the chemical composition of the ice in disks that form planets, and what organic molecules are ...

  • 2025-07-09
    Scientists have uncovered a hidden structure inside the Universe’s most common ice—found on comets, moons, and interstellar dust—challenging decades of belief. What was thought to be shapeless, “amorphous” ice is actually embedded with tiny crystals, each about the width of a DNA strand. These crystals could reshape how we understand ...

  • 2025-06-28
    A surprising discovery from a tiny grain of asteroid Ryugu has rocked scientists' understanding of how our Solar System evolved. Researchers found djerfisherite—a mineral typically born in scorching, chemically reduced conditions and never before seen in Ryugu-like meteorites—inside a sample returned by Japan’s Hayabusa2 mission. Its presence suggests either Ryugu ...

    The LSST camera at the Vera C. Rubin Observatory has released its jaw-dropping first images, each capturing 45 times the area of the full moon in one shot. Over the next ten years, this cosmic giant will scan the southern sky in ultra-HD, helping scientists uncover everything from asteroids to ...

    Imagine printing your Martian home from dust, sunlight, and a bit of biology. A new synthetic lichen system uses fungi and bacteria to grow building materials directly from Martian soil, completely autonomously and without human help.

GADA METEORĪTS
2025
Meteoriti.LV vietne tiks pakāpeniski papildināta ar plašu pamatinformāciju par meteorītiku un ar to saistitām astronomijas nozarēm. Uzzināsiet, vai "meteorīti dabā sastopami retāk par dimantiem", cik tie ir veci un kāda ir to izcelsme. Atradīsiet atbildes uz jautājumiem: Vai meteorīti ir bīstami? Kādi meteorīti atrodami Latvijā un kur tos var apskatīt? Vai Latvijā ir vērts meklēt meteorītus? Ko meteorītu izpēte pastāsta mums par Zemes un Saules sistēmas izcelšanos? Ceram, ka tas radīs vēlmi arī jums pašiem novērot Zemes kosmiskos viesus - meteorus, un, varbūt, pat kļūt par īstiem meteorītu medniekiem!
Veiksmīgu novērošanu!
