Elon Musk’s SpaceX said on Friday its upcoming Starship test flight would include the rocket’s first attempt to deploy payloads in space by releasing 10 model Starlink satellites, a key demonstration for Starship’s potential in the satellite launch market.

“While in space, Starship will deploy 10 Starlink simulators, similar in size and weight to next-generation Starlink satellites as the first exercise of a satellite deploy mission,” SpaceX said in a blog post on its website.

The Starship flight from SpaceX’s sprawling Boca Chica, Texas facilities, tentatively planned for later this month, will mark the seventh demonstration in a test-to-failure style of rocket development where the company tests new upgrades with each flight.

In October, Starship’s “Super Heavy” first stage booster returned to its launch pad’s giant mechanical arms for the first time, a milestone for its fully reusable design.

The rocket’s sixth test flight in November, attended by U.S. President-elect Donald Trump, achieved similar mission objectives – besides the landing of Super Heavy, which was forced to target a water landing on the Gulf of Mexico because of a launchpad problem.

Starship is the centerpiece of SpaceX’s future satellite launch business – an area it currently dominates with its partially reusable Falcon 9 – as well as Musk’s dreams to colonize Mars.

The rocket’s power, stronger than the Saturn V rocket that sent Apollo astronauts to the moon in the last century, is key for launching huge batches of satellites into low-Earth orbit and is expected to rapidly expand the company’s Starlink satellite internet network.

SpaceX is under contract with NASA to land U.S. astronauts on the moon later this decade using Starship.

Musk, SpaceX’s founder and CEO, has become a close ally of Trump who has made getting to Mars a more prominent goal for the incoming administration.

Crystal Cooling Technology Could Change How We Cool Fridges and AC Units

A novel crystal-based technology has been identified as a potential solution for sustainable cooling systems. Current refrigeration and air conditioning devices rely on liquid-based systems to absorb heat through evaporation and condensation. While effective, these fluids contribute significantly to greenhouse gas emissions when leaked, intensifying global warming. Efforts to counteract this environmental impact have led to the development of an alternative cooling mechanism based on plastic crystals, which possess a unique molecular structure capable of transforming under pressure.

How the Technology Works

According to researchers at Deakin University, plastic crystals exhibit a transformative ability when subjected to extreme pressure. Their molecular orientation shifts from a disordered state to a structured grid, absorbing heat as the pressure is released. This heat absorption process facilitates cooling, providing a climate-friendly alternative to traditional refrigerants.

Unlike earlier materials, which required high ambient temperatures for similar transitions, the newly developed crystals operate effectively between -37 degree Celsius and 10 degree Celsius. This range aligns with typical household refrigeration and freezing needs, presenting a significant step forward in sustainable cooling technologies.

Challenges in Implementation

According to a New Scientist report, high-pressure requirements, equivalent to conditions thousands of metres underwater, remain a major hurdle for practical application. Dr. Jenny Pringle, a lead researcher in the study, acknowledged this limitation and emphasised the need for further development to address these constraints.

Concerns have also been raised by experts about the long-term performance of these crystals. Bing Li, affiliated with the Chinese Academy of Sciences, pointed out the potential reduction in heat absorption capacity over time due to molecular strain, while expressing optimism about future advancements.

Potential Impact

David Boldrin from the University of Glasgow told the publication about the significant potential of this innovation, suggesting that it could help decarbonise the cooling industry. While the technology remains confined to laboratory settings, its success could herald a substantial reduction in the environmental footprint of refrigeration systems.

Experts remain hopeful that continued research will overcome current obstacles, bringing this promising solution closer to widespread adoption.

Solar Missions in 2025: The Spacecrafts That Will Study the Sun This Year

The study of the Sun and its influence on the solar system is expected to make significant strides in 2025. The year will bring new developments driven by an active solar cycle, upcoming spacecraft missions, and a strategic roadmap for the next decade. Researchers are focused on unlocking key mysteries of the sun, whose activity impacts life on Earth and extends far beyond Pluto. These efforts aim to provide critical insights into solar processes and their effects across the solar system.

Solar Cycle 25 and Ongoing Activity

According to NASA, the Sun is currently in the maximum phase of its 11-year activity cycle. This period has produced numerous solar flares and outbursts that are being closely monitored. Instruments such as the largest solar telescope and spacecraft that have made record-setting approaches to the sun have played a key role in collecting data. Despite not breaking records, Solar Cycle 25 has generated valuable observations that have propelled research forward.

Upcoming Spacecraft Missions

As per NASA, six new missions are scheduled for launch in 2025. These include the Interstellar Mapping and Acceleration Probe (IMAP), designed to chart the sun’s outer sphere of influence, and the Escape and Plasma Acceleration and Dynamics Explorers (ESCAPADE), which will study space weather around Mars. The Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission, involving four small satellites, will examine the sun’s outer atmosphere.

A Decadal Blueprint for Research

The recently released heliophysics decadal report outlines research priorities for the next ten years. Among the proposals are two large-scale projects, including a mission deploying over 26 spacecraft to study Earth’s magnetic field and auroras. Another mission aims to explore the sun’s poles over a full solar cycle, a region considered pivotal to understanding the sun’s magnetic field dynamics.

Efforts will also be supported by the Next Generation Global Oscillations Network Group (ngGONG), enhancing the capability to study the solar interior. With these initiatives, heliophysics is positioned to address long-standing questions and open new research avenues in 2025.

Researchers Reveal Crucial Ocean Processes That Help Fight Climate Change

Organic carbon preservation in ocean sediments, a phenomenon critical to the Earth’s carbon cycle, has been illuminated by new research. The study explores mechanisms that prevent organic carbon from breaking down, a process vital for climate regulation. Preserved carbon, over time, can transform into fossil fuels, locking away carbon dioxide—a leading contributor to climate change. These findings offer insights into the Earth’s natural systems that regulate carbon levels and influence the formation of oil and gas reserves.

Study Identifies Key Carbon Preservation Mechanisms

According to a study led by scientists from The University of Manchester and the University of Leeds and published in the journal Nature Geoscience, two primary processes—sorption and molecular transformation—are crucial for carbon storage in ocean sediments.

Sorption involves the uptake of carbon by mineral surfaces, while molecular transformation converts small, reactive molecules into larger, stable forms. The study used a comprehensive model, integrating real-world sediment data, to identify these processes as dominant contributors to carbon preservation.

AI Provides Deeper Insights into Carbon Storage

Artificial intelligence (AI) was utilised to enhance the study’s model, enabling accurate predictions of carbon storage efficiency. Dr. Peyman Babakhani, a lead researcher, highlighted that AI helped clarify complex environmental processes. The research revealed that carbon preservation in sediments is nearly three times higher than earlier estimates, aligning closely with observed data.

Implications for Climate Change Mitigation

The findings underline the importance of sorption and molecular transformation in protecting organic matter from degradation and facilitating its burial in deeper sediment layers. This preserved carbon can eventually become fossil fuels, effectively keeping carbon dioxide from entering the atmosphere. These insights could influence climate change strategies, such as ocean fertilisation, aimed at enhancing natural carbon storage mechanisms.

By shedding light on these processes, the study opens pathways for managing carbon emissions and leveraging the ocean’s role in the global carbon cycle.
