    Martian Volcanoes: Uncovering Jezero Mons and the Secrets of the Red Planet
    Jul 4 2025
    In this episode of SpaceTime, we uncover remarkable insights into Mars, Mercury, and the latest developments in space exploration.
    Hidden Martian Volcano: Jezero Mons
    Scientists have identified a previously overlooked volcano, Jezero Mons, located on the rim of Jezero Crater, where NASA's Perseverance rover is actively collecting samples. This discovery could provide vital clues about Mars' volcanic history and habitability, suggesting that the region may have supported life due to the interplay of volcanic heat and water. The findings, published in Communications Earth and Environment, highlight the need for further exploration of Mars' geology, as volcanism plays a crucial role in understanding the planet's past.
    Tidal Forces Shaping Mercury's Cliffs
    A new study published in Geophysical Research Planets proposes that tidal forces from the Sun may have contributed to the deformation of Mercury's towering cliffs. Traditionally attributed to cooling and contraction, this research indicates that the planet's unique orbital dynamics could also influence its geological features. The BepiColombo mission, scheduled to arrive at Mercury next year, aims to gather data that could validate these findings and enhance our understanding of the planet's evolution over billions of years.
    Axiom Space's AX4 Mission Arrives at the ISS
    The Axiom Space AX4 mission has successfully docked at the International Space Station for a 14-day stay. This mission, featuring a diverse international crew, aims to conduct over 60 scientific and commercial experiments, furthering Axiom's goal of establishing a private space station in low Earth orbit. Despite facing multiple delays, the mission underscores the growing role of private companies in space exploration.

    Parker Solar Probe's Historic Close Approach to the Sun
    NASA's Parker Solar Probe has achieved a remarkable milestone, completing its 24th close flyby of the Sun at a record distance of just 6.2 million kilometers from the solar surface. During this encounter, the probe reached speeds of 687,000 kilometers per hour, gathering invaluable data on solar wind and solar activity as the Sun approaches its solar maximum. The mission aims to deepen our understanding of the Sun's behavior and its impact on space weather, which can affect technology and human activities on Earth.
    Deep Earth Pulses: A New Ocean in the Making
    Scientists have detected rhythmic surges of molten rock rising from deep within the Earth beneath Africa, revealing a dynamic mantle plume that is gradually tearing the continent apart. This groundbreaking research, published in Nature Geoscience, indicates that the Afar region is experiencing the birth of a new ocean basin due to the interaction between tectonic plates and the pulsing mantle below. The study highlights the complex relationship between the Earth's interior and surface processes, offering new insights into volcanic activity and continental breakup.
    Aeris Rocket Launch Window Opens
    Mission managers at Gilmour Space are preparing for the opening of a new launch window for their Ares orbital rocket's first test flight, set to begin tomorrow. Following earlier technical issues, the team is closely monitoring weather conditions as they aim to launch the first all-Australian designed and built launch vehicle since the 1970s. With ambitious plans for future versions capable of carrying heavier payloads, this test flight marks a significant step in Australia's growing space industry.
