  • Martian dust could pose health risks to future astronauts
    on March 31, 2025 at 4:21 pm

    Inhaling dust particles from the Red Planet over long periods of time could put humans at risk of developing respiratory issues, thyroid disease and other health problems.

  • Fluorescent caves could explain how life persists in extraterrestrial environments
    on March 25, 2025 at 4:01 pm

    Deep below the Earth’s surface, rock and mineral formations lay hidden with a secret brilliance. Under a black light, the chemicals fossilized within shine in brilliant hues of pink, blue and green. Scientists are using these fluorescent features to understand how the caves formed and the conditions for supporting life in extreme, and even extraterrestrial, environments.

  • Organic molecules of unprecedented size discovered on Mars
    on March 24, 2025 at 7:24 pm

    The longest organic molecules identified to date on Mars have recently been detected. These long carbon chains, containing up to 12 consecutive carbon atoms, could exhibit features similar to the fatty acids produced on Earth by biological activity. The lack of geological activity and the cold, arid climate on Mars have helped preserve this invaluable organic matter in a clay-rich sample for the past 3.7 billion years. It therefore dates from the period during which life first emerged on Earth.

  • Oxygen for Mars
    on March 24, 2025 at 3:38 pm

    To mitigate global climate change, emissions of the primary culprit, carbon dioxide, must be drastically reduced. A newly developed process helps solve this problem: CO2 is directly split electrochemically into carbon and oxygen. Oxygen could also be produced in this way under water or in space — without requiring stringent conditions such as pressure and temperature.

  • Oxygen discovered in most distant known galaxy
    on March 20, 2025 at 6:50 pm

    Astronomers have detected oxygen in the most distant known galaxy, JADES-GS-z14-0. This record-breaking detection is making astronomers rethink how quickly galaxies formed in the early Universe.

      by Dacia Massengill on April 1, 2025 at 5:15 pm

      Since it began in 1958, NASA has been charged by law with spreading the word about its work to the widest extent practicable. From typewritten press releases to analog photos and film, the agency has effectively moved into social media and other online communications. NASA’s broad reach across digital platforms has been recognized by the

    • NASA’s SPHEREx Takes First Images, Preps to Study Millions of Galaxies
      by Anthony Greicius on April 1, 2025 at 4:55 pm

      Processed with rainbow hues to represent a range of infrared wavelengths, the new pictures indicate the astrophysics space observatory is working as expected. NASA’s SPHEREx (short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) has turned on its detectors for the first time in space. Initial images from the

    • Studying Ice for the Future of Flight
      by Monika Luabeya on April 1, 2025 at 4:52 pm

      Thomas Ozoroski, a researcher at NASA’s Glenn Research Center in Cleveland, takes icing accretion measurements in October 2024 as part of transonic truss-braced wing concept research. In the future, aircraft with long, thin wings supported by aerodynamic braces could help airlines save on fuel costs – but those same wings could be susceptible to ice

    • Artemis II Core Stage Integration – Complete!
      on March 31, 2025 at 6:42 pm

      Teams with NASA’s Exploration Ground Systems and primary contractor Amentum integrate the SLS (Space Launch System) Moon rocket with the solid rocket boosters onto mobile launcher 1 inside High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center on Sunday, March 23, 2025. Artemis II is the first crewed test flight under NASA’s Artemis campaign and is another step toward missions on the lunar surface and helping the agency prepare for future human missions to Mars.

      In this February 1944 publicity photo, men stand in front of turning vanes inside the Altitude Wind Tunnel (AWT) at the National Advisory Committee for Aeronautics Aircraft Engine Research Laboratory. The AWT was the only wind tunnel capable of testing full-size aircraft engines in simulated altitude conditions. A large wooden drive fan, located on the other side of these vanes, created wind speeds up to 500 miles per hour.

    • Space Debris: Is it a Crisis?
      on April 1, 2025 at 7:00 am

      Video: 00:08:04 Space Debris: Is it a Crisis?The European Space Agency’s short documentary film ‘Space Debris: Is it a Crisis?’ on the state of space debris premiered at the 9th European Conference on Space Debris on 1 April 2025.Earth is surrounded by thousands of satellites carrying out important work to provide telecommunications and navigation services, help us understand our climate, and answer fundamental questions about the Universe.However, as our use of space accelerates like never before, these satellites find themselves navigating increasingly congested orbits in an environment criss-crossed by streams of fast-moving debris fragments resulting from collisions, fragmentations and breakups in space.Each fragment can damage additional satellites, with fears that a cascade of collisions may eventually render some orbits around Earth no longer useable. Additionally, the extent of the harm of the drastic increase in launches and number of objects re-entering our atmosphere and oceans is not yet known.So, does space debris already represent a crisis?The documentary explores the current situation in Earth’s orbits and explains the threat space debris poses to our future in space. It also outlines what might be done about space debris and how we might reach true sustainability in space, because our actions today will have consequences for generations to come. ESA’s Space Safety ProgrammeESA’s Space Safety Programme aims to safeguard the future of spaceflight and to keep us, Earth and our infrastructure on the ground and in space safe from hazards originating in space.From asteroids and solar storms to the human-made problem of space debris, ESA works on missions and projects to understand the dangers and mitigate them.In the longer term, to ensure a safe and sustainable future in space, ESA aims to establish a circular economy in space. To get there, the Agency is working on the technology development necessary to make in-orbit servicing and zero-debris spacecraft a reality.
