    Watching meteoroids enter the Earth’s atmosphere and streak across the sky as the visual spectacle known as meteors, it is one of the most awe-inspiring spectacles on Earth, often exhibiting multiple colors as they blaze through the atmosphere, which often reveals their mineral compositions. But what if we could detect ...

    Mars holds a very special place in our hearts. Chiefly because of all the other planets in the Solar System Mars is probably the place we are going to find some tantalising clues or maybe even evidence of prehistoric life. NASA Perseverance Rover has been trundling around the Jezero Crater ...

    Last September NASA's OSIRIS-REx spacecraft successfully returned samples from the asteroid Bennu, seven years after its launch. Jeff Foust reviews a book by the mission's principal investigator that describes the long effort to develop the mission and how it overcame obstacles along the way.
  • 2024-04-29
    Mars scientists hoped they would have a better idea of when and how they would get samples back from Mars after NASA completed an internal study of the Mars Sample Return program. Instead, as Jeff Foust reports, NASA is now turning to industry for help on how to reduce the ...

    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.

    Universe Today has had the privilege of spending the last several months venturing into a multitude of scientific disciplines, including impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, planetary geophysics, cosmochemistry, meteorites, radio astronomy, extremophiles, organic chemistry, and black holes, and their importance in helping teach scientists ...
  • 2024-05-27
    NASA is actively working to return surface samples from Mars in the next few years, which they hope will help us better understand whether ancient life once existed on the red planet's surface billions of years ago. But what about atmospheric samples? Could these provide scientists with better information pertaining ...

    Although Mars presents a barren, dusty landscape with no signs of life so far, its geological features such as deltas, lakebeds, and river valleys strongly suggest a past where water once flowed abundantly on its surface. To explore this possibility, scientists examine sediments preserved near these formations. The composition of ...
  • 2024-05-01
    A research team using the ChemCam instrument onboard NASA's Curiosity rover discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, which indicates that the sediments were formed in a river, delta, or near the shoreline of an ancient lake. The results were published today in Journal ...

    Atmospheric scientists get a little more excited with every rock core NASA's Perseverance Mars rover seals in its titanium sample tubes, which are being gathered for eventual delivery to Earth as part of the Mars Sample Return campaign. Twenty-four have been taken so far.
  • 2024-06-20
    Four and a half billion years ago, our solar system was a cloud of gas and dust swirling around the sun, until gas began to condense and accrete along with dust to form asteroids and planets. What did this cosmic nursery, known as a protoplanetary disk, look like, and how ...
  • 2024-06-17
    A multi-institutional team of planetary scientists has learned more about the early composition of the solar system by studying a meteorite named Northwest Africa 14250. In their study, published in the journal Science Advances, the group used a scanning tunneling microscope to learn more about the isotopic makeup of clasts ...

    For more than a decade, Western University planetary geologist Gordon "Oz" Osinski has led expeditions to Kamestastin Lake in Labrador. The environment is a perfect training ground because the properties and rock formations—created by the violent impact (and extreme heat) of an asteroid 36 million years ago—uniquely mimic the surface ...

    In 2021, NASA's Perseverance rover landed in the Jezero Crater on Mars. For the next three years, this astrobiology mission collected soil and rock samples from the crater floor for eventual return to Earth. The analysis of these samples is expected to reveal much about Mars' past and how it ...

    ESA's Hera asteroid mission and its two CubeSats interacted as if they were in space, within the foam pyramid-lined walls of the Agency's Maxwell test chamber in the Netherlands. The trio communicated together, sharing data and ranging information at the same time as their Hera mothership received commands from its ...

    So far, scientists have found around 34,000 near-Earth asteroids (NEAs) that could serve as humanity's stepping stone to the stars. These balls of rock and ice hold valuable resources as we expand throughout the solar system, making them valuable real estate in any future space economy. But the 34,000 we ...

    NASA's LRO (Lunar Reconnaissance Orbiter) imaged China's Chang'e 6 sample return spacecraft on the far side of the moon on June 7. Chang'e 6 landed on June 1, and when LRO passed over the landing site almost a week later, it acquired an image showing the lander on the rim ...

    Iron meteorites are remnants of the metallic cores of the earliest asteroids in our solar system. Iron meteorites contain refractory metals, such as iridium and platinum, that formed near the sun but were transported to the outer solar system. New research shows that for this to have happened, the protoplanetary ...

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!
