  • The Exploration of Space Asteroids: The Fossils of the Universe

    The Exploration of Space Asteroids: The Fossils of the Universe
    Sep 6 2025
    Asteroids, often called “fossils of the solar system,” are remnants from its formation that offer clues about planetary origins and the potential beginnings of life. Dr. Neil Farber, Solar System Ambassador for NASA’s Jet Propulsion Laboratory, explains that some, known as near-Earth objects, pose impact risks—though large, dangerous collisions are rare—and NASA’s Near-Earth Object Surveyor mission aims to detect and track them to inform planetary defense strategies. Asteroids may also hold resources, such as metals or water, that could one day support space exploration, though current technology limits mining feasibility. Recent missions like OSIRIS-REx, Lucy, and Psyche are expanding our understanding of asteroid composition, history, and diversity, with findings including evidence of past water, amino acids, and nucleotide bases—key building blocks of life—raising intriguing questions about whether asteroids helped seed life on Earth.

  • Leveraging Space

    Leveraging Space
    May 15 2026
    Stem cell health in space matters for astronaut health and cancer research. Jessica Pham, UC San Diego, explains how spaceflight shapes normal hematopoietic stem cells and cancer stem cells through nano bioreactor studies, astronaut blood analysis, and tumor organoid work in low-Earth orbit. Pham examines increased cycling and reduced dormancy in space, reduced self-renewal after return, and ongoing research on cancer stem cells and their microenvironment, helping clarify how stem cells respond to spaceflight. This work helps explain how space conditions may change stem cell fitness over time and points toward a better understanding of astronaut health, long-duration missions, and cancer stem cell behavior.

  • 3rd Annual Global Astrobiotechnology Hub

    3rd Annual Global Astrobiotechnology Hub
    May 5 2025
    The 3rd Annual Global Astrobiotechnology Hub focuses on advancing the intersection of space exploration, biotechnology, and innovation. The program brings together scientists, researchers, and space professionals to discuss how space technologies can accelerate scientific breakthroughs, particularly in fields like personalized medicine and bioengineering. Key themes include the challenges of conducting real-time research in space, the need for specialized astronaut-scientists, and the potential of space for groundbreaking experiments, such as organoid growth and in-space manufacturing. Experts underscore the importance of public access to scientific data and highlight the role of new media in engaging the public with space research.
