  • Navigating the Cosmos: Planetary Science Developments in the US and Worldwide

    Navigating the Cosmos: Planetary Science Developments in the US and Worldwide
    2025/06/28
    In the past week, planetary science developments in the United States and worldwide have offered both new discoveries and forward-looking perspectives. At NASA, the push for planetary exploration continues despite ongoing challenges, including internal leadership uncertainties and the need for increased public and political advocacy. The nomination for the incoming NASA administrator was recently pulled by the Senate, which is now focusing on the reconciliation bill, according to the American Astronomical Society. This development could have implications for how planetary science missions are prioritized and funded in the near term.

    Meanwhile, in Florida, preparations for the Axiom Mission 4 launch to the International Space Station are under scrutiny. NASA, Axiom Space, and SpaceX have postponed the launch previously set for June 22 to ensure the readiness of the International Space Station after recent repair work in the Zvezda service module. The mission, which will carry astronauts from India, Poland, and Hungary, is considered historic for international cooperation and human spaceflight, with former NASA astronaut Peggy Whitson commanding the crew. The team remains in quarantine, awaiting a new launch date once all safety checks are complete, as reported directly by NASA.

    On the science front, researchers are making steady progress in understanding our solar system and beyond. A recent highlight from the Planetary Society notes that 2025 has been a banner year for space advocacy, with the Save NASA Science Campaign mobilizing tens of thousands of supporters to protect and advance planetary science. The campaign, which emerged in response to concerns about possible cuts to NASA’s science budget, has brought together academia, industry, and the international community to champion scientific discovery.

    As we enter summer, skywatchers in the United States have been treated to clear views of planets: Venus shines brightly in the eastern morning sky, while Mars is visible in the west after sunset and will soon pass close to Regulus in Leo, according to NASA’s monthly skywatching guide. Jupiter, low in the west early in June, will return to morning skies in July, and Saturn is now rising earlier each night, making for excellent planetary observation opportunities.

    Globally, the search for new worlds continues. Astronomers have confirmed a new gas giant exoplanet and are investigating the mysterious outer reaches of our solar system, where the elusive hypothetical "Planet Nine" may still be lurking. There is also ongoing research into so-called hycean worlds—planets with thick hydrogen atmospheres and deep oceans—which may have smaller, more challenging habitable zones than previously thought, according to recent scientific news from Phys.org. Additionally, planetary scientists are exploring new strategies for future Mars landings, with recent studies from the University of Mississippi suggesting that identifying the right landing site is critical for the success of long-term human exploration.

    In summary, this week in planetary science has seen a mix of mission readiness checks, continued advocacy for research funding, and scientific advances that deepen our understanding of planets both near and far. The field remains vibrant and collaborative, with ongoing contributions from both the United States and international partners.

  • Soaring Discoveries in Planetary Science: NASA's Landmark Collaborations and Cosmic Wonders

    Soaring Discoveries in Planetary Science: NASA's Landmark Collaborations and Cosmic Wonders
    2025/06/25
    In the past week, planetary science in the United States has drawn global attention with significant developments at NASA and new international collaborations. According to NASA, astronomers achieved a landmark by combining data from the Chandra X-ray Observatory and the James Webb Space Telescope to analyze the supernova remnant known as Cassiopeia A. This joint effort provided unprecedented insight into a mysterious structure within the debris called the Green Monster, first identified by the Webb telescope in 2023. The composite image, integrating X-ray, infrared, and optical data, is helping scientists better understand the aftermath of stellar explosions and the formation of elements critical to life on Earth.

    Meanwhile, skywatchers across the United States have been treated to a parade of planetary phenomena throughout June. NASA reports that Venus is shining brightly in the eastern pre-dawn sky, while Mars has been visible in the west after sunset and recently passed close to the star Regulus in the constellation Leo. Jupiter, after briefly gracing the evening sky, is expected to reappear in the early mornings of July. Saturn continues its gradual climb higher in the pre-dawn sky, moving away from Venus as the month progresses. Mercury will become visible low in the west toward the end of June, offering another spectacle for observers. These events coincide with the June solstice, marking the longest day of the year in the northern hemisphere and connecting skywatchers to traditions that stretch back thousands of years.

    On the human exploration front, NASA, in partnership with Axiom Space and SpaceX, postponed the launch of Axiom Mission 4 to the International Space Station to allow time for further evaluation of the station’s readiness. This mission will mark a historic international collaboration, with crewmembers representing the United States, India, Poland, and Hungary. The launch, originally scheduled for June 22, is on hold as NASA completes assessments following recent repair work on the station’s Zvezda service module. The crew is in quarantine, awaiting clearance to proceed from the Kennedy Space Center in Florida.

    Despite these scientific achievements, space policy debates continue in Washington. The Planetary Society summarizes ongoing concerns about proposed cuts to NASA’s science programs under the White House’s fiscal year 2026 budget. If enacted, these cuts would see NASA’s civil workforce drop to its lowest level since 1960, raising questions about the future pace of planetary exploration and discovery.

    Globally, excitement about Mars continues with scientists discussing the discovery of siderite-filled rocks there, supporting theories that ancient Mars once had a thick atmosphere and could have harbored life, according to the SETI Institute. These insights, paired with American-led collaboration and technological advances, underscore the dynamic and rapidly evolving landscape of planetary science both in the United States and beyond.

  • Soaring Discoveries and Future Visions: Planetary Science Advances in the U.S. and Worldwide

    Soaring Discoveries and Future Visions: Planetary Science Advances in the U.S. and Worldwide
    2025/06/21
    Planetary science in the United States and worldwide is experiencing a dynamic period marked by significant mission updates, scientific findings, and future exploration planning. In the United States, NASA continues its focus on reestablishing contact with the Lunar Trailblazer spacecraft, a part of the Small Innovative Missions for Planetary Exploration or SIMPLEx program. Contact with the spacecraft was lost just after launch in February 2025, but mission controllers remain hopeful as increasing sunlight during the spring and early summer could recharge its batteries, potentially allowing for renewed communication and continuation of its lunar mapping objectives. If successful, the spacecraft could return to lunar orbit and resume its search for water ice and minerals. NASA's contingency planning includes a review to decide the fate of the mission should efforts to regain contact prove successful by mid June, otherwise closure procedures will begin. An independent review board is also examining the issues to glean lessons for future cost effective planetary missions, reflecting NASA's focus on innovation and risk management for advancing lunar science.

    Meanwhile, skywatchers across the country are benefiting from optimal planetary viewing conditions. Venus shines brightly in the morning sky, Mars remains visible in the west after sunset, and Saturn gradually rises earlier each night. The June solstice and clear skies provide further opportunities to observe not only the planets but also the structure of our own galaxy, as described by NASA’s monthly skywatching guide. These observations support ongoing public interest in planetary science and engagement with astronomy.

    Major research updates this week include findings from the Perseverance rover on Mars. According to Purdue University’s Department of Earth, Atmospheric, and Planetary Sciences, there is strong evidence of a volcano near Jezero Crater, the rover’s landing site. The rover may have collected samples that, once analyzed, could help date the volcanic activity, offering new insights into the geologic history of Mars. This discovery adds an important dimension to our understanding of Martian evolution and could inform future missions.

    Jupiter’s moon Io is also in the spotlight. Recent flybys have challenged long standing theories about its interior, revealing that much remains unknown about this volcanically active world. These findings are reshaping planetary scientists’ approach to studying geologically dynamic moons in our solar system.

    Experts in the United States are further shaping the direction of human space exploration. A new consensus report led by Purdue University faculty has outlined key U S priorities for sending humans to Mars. The report emphasizes the need to develop mission architectures, invest in critical technologies, mitigate risks, and foster collaborations with international partners and private industry. Together, these advances underscore a period of rapid progress and renewed ambition in planetary science, both nationally and globally.
