  • NASA's Lunar Trailblazer Mission Leads July's Surge in Planetary Science Developments

    NASA's Lunar Trailblazer Mission Leads July's Surge in Planetary Science Developments
    2025/07/05
    July has opened with a surge of planetary science developments in the United States and on the international stage. Among the most closely watched efforts is NASA’s extended attempt to regain contact with the Lunar Trailblazer spacecraft. According to NASA, after contact was lost the day after its launch on February twenty-sixth, the small satellite entered a low power state with its solar panels not optimally oriented toward the sun, leaving it generating insufficient power to charge its batteries. Since then, ground-based telescopes and global radio antennas have been tracking the spacecraft’s position and detecting any signal. NASA extended its recovery efforts into early July, as updated trajectory modeling predicted that increasing sunlight might provide enough energy for the spacecraft to reboot and transmit. If contact is restored and the system remains functional, Lunar Trailblazer could still complete its planned mission to study water on the Moon. Should the effort prove unsuccessful, NASA will evaluate other options or conclude the mission, illustrating both the promise and peril inherent in lunar exploration.

    At the same time, the night sky is offering a series of planetary conjunctions and viewing opportunities, as highlighted by NASA’s Jet Propulsion Laboratory in California. Venus continues to dominate the eastern sky in the early morning, set against the backdrop of the Pleiades star cluster and flanked by the stars Aldebaran and Capella. Mars appears in the western evening sky, forming a vivid pairing with the crescent moon on July twenty-eighth. Jupiter is now returning to the morning sky, steadily rising with each day and heading towards a notable conjunction with Venus in August. Mercury offers a fleeting spectacle in the western sky just after sunset during the first week of July, while Saturn becomes visible around midnight, rising high by dawn. These events are being observed across the United States, with clear summer skies providing optimal conditions for astronomers and amateur skywatchers.

    Emerging patterns also include increased public engagement due to exceptionally active solar weather. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center reports that a recent coronal mass ejection from the sun created conditions favorable for the aurora borealis, which became visible in as many as fourteen northern U.S. states including Wisconsin and Oregon. The resulting geomagnetic storm, rated at a Kp index of four to five, brought the northern lights to audiences far south of their usual range, underscoring how space weather phenomena can invigorate public interest and expand planetary science outreach efforts.

    Globally, scientific collaboration is driving new advances. Boeing has delivered two new O3b mPOWER satellites, demonstrating technological innovation in satellite payload design, while in Colorado, satellite messaging technology aided a dramatic mountain rescue, reinforcing the practical impact of planetary science technologies on day-to-day life. As July unfolds, skywatchers and scientists alike are reminded of the dynamic interplay between celestial events, ambitious exploration missions, and the unpredictable nature of space, all of which are shaping the future of planetary science in the United States and around the world.

  • Groundbreaking Discoveries in Planetary Science Captivate Researchers Worldwide

    Groundbreaking Discoveries in Planetary Science Captivate Researchers Worldwide
    2025/07/02
    A wave of recent developments in planetary science is capturing the attention of researchers across the United States and the world. According to the July 2025 Space News Digest, the Vera Rubin Observatory in Chile, funded in part by the National Science Foundation in the United States, has officially embarked on its decade-long Legacy Survey of Space and Time. This observatory utilizes the most sophisticated 3.2 gigapixel camera ever built to capture the southern sky every few days. Within its first full week of operations, it has already revealed millions of distant galaxies and more than two thousand new asteroids. The goal over the next ten years is to catalog more than forty billion cosmic objects, including stars and asteroids, offering fresh insights into the structure of our Milky Way and the broader universe. The observatory’s data is open-access, which is expected to accelerate global collaboration and innovative discoveries by researchers both in the United States and internationally. Scientists are particularly excited by its potential to enable time-domain astronomy at an unprecedented scale, allowing for the tracking of transient events and improving our understanding of dark matter and dark energy.

    Meanwhile, NASA’s Lucy spacecraft continues its journey through the main asteroid belt. NASA reports that the Lucy mission has just completed a successful flyby of the asteroid Donaldjohanson in April, gathering images and data that the team is now analyzing. This event served as a dress rehearsal for Lucy’s main encounters with the Jupiter Trojan asteroids, which are set to begin in August 2027 with a flyby of the asteroid Eurybates. The mission aims to observe a group of these ancient objects, some accompanied by their own small satellites, to help scientists understand the origins of our solar system. The Lucy spacecraft is currently in a quiet cruise phase, traveling away from the Sun at more than thirty thousand miles per hour as it prepares for these landmark encounters.

    In the realm of planetary observation from Earth, the U S National Oceanic and Atmospheric Administration’s Space Weather Prediction Center forecasts an unusually widespread display of the northern lights this week. A coronal mass ejection from the Sun is causing a geomagnetic storm, making the aurora borealis visible in as many as fourteen U S states, including Wisconsin and Oregon. This phenomenon not only provides a stunning natural spectacle for observers but also serves as an opportunity for atmospheric and planetary scientists to monitor solar activity and its effects on Earth’s magnetosphere.

    These highlights reflect an emerging pattern of increasingly powerful observational tools, global cooperation, and sophisticated missions. They are pushing the boundaries of what is possible in planetary science and are generating a wealth of data that will shape our understanding of both our solar system and the broader universe in the years ahead.

  • 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.
