    Concerns about the budget and plans for NASA's Mars Sample Return (MSR) program came to a head last week when JPL laid off more than 500 employees, citing budget uncertainty about the program. Jeff Foust reports on the issues that have put the future of MSR into question for some.
  • 2024-02-05
    Ingenuity, whose mission ended last month, was a first-of-its-kind Mars helicopter with no guarantees more will follow soon. Ari Allyn-Feuer discusses how sending a large number of similar helicopters could advance Martian exploration in novel ways.
  • 2023-09-25
    On Sunday, NASA's OSIRIS-REx spacecraft returned to Earth, dropping off a capsule containing samples collected from the asteroid Bennu. Jeff Foust reports on the success of the first part of NASA's "Asteroid Autumn" that includes a launch and a flyby.
  • 2023-09-11
    Last month, a paper claimed to have found evidence for interstellar meteorites at the bottom of the Pacific, a claim other scientists have treated skeptically. Jeff Foust review a book by the scientist who is the lead author of that study and other efforts using science to look for interstellar ...

    The Fox reality TV series "Stars on Mars" wrapped up recently with one "celebronaut" crowned as winner. The series, Dwayne Day explains, also provided useful lessons for real missions to the Red Planet.
  • 2023-07-17
    A Senate appropriations bill released last week would slash funding for NASA's Mars Sample Return program and threaten it with cancellation. Jeff Foust reports on the new fiscal challenges that efforts to return samples from Mars have encountered.

    In this image from Feb. 12, 2024, engineers lift a mast into place on NASA's VIPER (Volatiles Investigating Polar Exploration Rover) robotic moon rover. VIPER's mast and the suite of instruments affixed to it look a lot like the rover's "neck" and "head." The mast instruments are designed to help ...

    Universe Today has explored the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, planetary geophysics, and cosmochemistry, and how this myriad of intricately linked scientific disciplines can assist us in better understanding our place in the cosmos and searching for life beyond Earth.
  • 2024-03-28
    Universe Today has had some fantastic discussions with researchers on the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, and planetary geophysics, and how these diverse scientific fields can help researchers and the public better understand the search for life beyond Earth.

    Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new Johns Hopkins University-led research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that ...
  • 2024-02-26
    Life on our planet appeared early in Earth's history. Surprisingly early, since in its early youth our planet didn't have much of the chemical ingredients necessary for life to evolve. Since prebiotic chemicals such as sugars and amino acids are known to appear in asteroids and comets, one idea is ...

    Seven years from now, in April 2031, ESA's Juice mission will fly past Jupiter's moon Callisto, offering scientists a tantalizing glimpse at the mysterious, cratered alien world.
  • 2024-04-16
    Ceres, the largest asteroid in our solar system, harbors a dark secret: extremely young ice deposits in permanently shadowed craters near its poles. If that sounds vaguely familiar, it's because our moon and planet Mercury also have such polar ice deposits, which have been studied for decades.
  • 2024-04-16
    Evidence from the fragments of a destroyed asteroid suggests that the shift in the positions of the giant planets in our solar system billions of years ago happened between 60–100 million years after the solar system's formation and could have been key to the formation of our moon.

    Using artificial intelligence, satellite observations, and climate model projections, a team of researchers from Switzerland and Belgium calculate that for every tenth of a degree of increase in global air temperature, an average of nearly 9,000 meteorites disappear from the surface of the ice sheet. This loss has major implications, ...

GADA METEORĪTS
2020
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!
