NASA Selects Scientists to Join Lucy Mission Studying Jupiter's Trojan Asteroids
Los Angeles CA (SPX) Feb 28, 2025 NASA has chosen eight scientists to participate in its Lucy mission, an initiative aimed at studying the Jupiter Trojan asteroids. These celestial bodies, considered remnants from the early solar system, follow stable orbits linked to Jupiter but remain at significant distances from the planet. The Lucy mission's Participating Scientist Program for the L4 Trojans enables researchers to contribute new insights into the nature and composition of these asteroids. The Lucy spacecraft, launched in 2021 ... read more |

Traces of ancient brine discovered on the asteroid Bennu contain minerals crucial to life
Washington DC (SPX) Jan 30, 2025 A new analysis of samples from the asteroid Bennu, NASA's first asteroid sample captured in space and delivered to Earth, reveals that evaporated water left a briny broth where salts and minerals allowed the elemental ingredients of life to intermingle and create more complex structures. The discovery suggests that extraterrestrial brines provided a crucial setting for the development of organic compounds. In a paper published, Jan. 29, in the journal Nature, scientists at the Smithsonian's Nation ... read more
