Future Earth

New research reported by Phys.org suggests the Sun, as it ages and loses mass toward the end of its life, could destabilize planetary orbits and break apart the solar system earlier than previous estimates indicated. The findings refine models of stellar evolution and the long-term fate of Earth and neighboring planets, prompting discussion among astronomers and space enthusiasts about the timescales involved.

Astronomers say a star is on a trajectory that will eventually bring it into our solar system, and that such an event has happened before in Earth's history. Reports note that past close stellar flybys may have disturbed comets in the outer solar system, raising questions about what a future encounter could mean for planetary orbits and long-term space safety.

Geologists say a fissure in the Earth's crust is thinner than previously believed, suggesting it could mark the early stages of continental breakup and the formation of a new ocean. The finding, reported by Acorda Cidade, is drawing attention in Brazil as readers discuss how slowly continents split and what a future ocean basin would mean for the affected region.

Researchers at the University of Rochester are studying microscopic fossils to reconstruct how Earth's oceans have changed over millions of years. By analysing chemical and physical signals preserved in these tiny remains, scientists can track shifts in ocean temperature, chemistry and circulation, offering clues about how marine environments responded to past climate change and what that may mean for the future.

NASA is moving forward with plans to hand over low-Earth orbit operations to commercial space stations as the International Space Station approaches retirement. The agency aims to transition to privately operated destinations to maintain a continuous human presence in orbit. Industry partners are developing new orbital platforms under NASA's commercialization strategy.

Researchers are examining how coast redwoods, among the tallest and oldest trees on Earth, are coping with intensifying heat and drought linked to climate change. The question of whether these mighty trees can survive a hotter, drier future is drawing attention, with scientists studying stress signals in the canopy and what the findings mean for the forests' survival.

A biologist at the University of Louisiana at Lafayette is conducting space research examining whether plants could be grown in lunar conditions, an early step toward possible gardening on the Moon. The work looks at how plants might handle water and resources in the lunar environment, with implications for future long-duration missions and sustained human presence beyond Earth.

Germany is moving to reinforce sustainability research through the German Committee Future Earth, a national body linked to the international Future Earth initiative. Writing in Open Access Government, commentators argue the committee can better connect scientists, policymakers and funders to tackle climate, biodiversity and development challenges. The discussion highlights how national structures can support global sustainability science.

NASA has issued a request for proposals for commercial space stations as it moves forward with plans for life after the International Space Station. The step signals the agency's intent to transition low Earth orbit operations to private operators, with companies expected to compete to build and run future orbital destinations.

Honda is developing a robotic lab assistant intended to operate aboard future commercial space stations, according to Universe Today. The system would support astronauts with laboratory tasks in orbit as low-Earth orbit research shifts from the International Space Station to privately operated facilities. The announcement highlights how automakers and consumer robotics firms are moving into space research support roles.

Google has launched its AI chips into space, placing them aboard satellites in orbit around Earth. The move suggests the company is exploring whether space-based hardware could support artificial intelligence workloads beyond traditional ground-based data centres. Details remain limited, but the announcement has drawn attention given the growing demand for AI computing capacity and the rising interest in orbital data infrastructure.

Elon Musk claims SpaceX could eventually be worth more than the whole of Earth's current economy, an extraordinary projection for the private space company. Such a valuation would require breakthroughs like large-scale Mars colonization, massive satellite expansion, and revenue streams far beyond today's space industry, which Musk argues are achievable over the long term.

Iran reports progress on its Saman space tug, a transfer vehicle using liquid-fuel propulsion designed to move satellites into higher orbits. Officials say the technology is intended to support future satellite constellations and operations beyond low Earth orbit. The development highlights Iran's continued push to expand its civilian space programme despite international scrutiny and sanctions.
