The article discusses a novel design for space-based data centers developed by researchers at the University of Pennsylvania, addressing the scalability challenges of orbiting data centers. Unlike traditional concepts that rely on constellations of numerous independent satellites or futuristic, robot-assembled structures, this design uses long, tether-like cables composed of thousands of individual computing nodes arranged like beads on a string. These tethers, stretching kilometers into space, are stabilized passively by natural orbital forces and solar radiation pressure, eliminating the need for complex adjustments or external power for orientation. This approach leverages well-understood tether technology to enable large-scale deployment capable of delivering up to 20 megawatts of computing power. Key advantages of this tether-based system include reduced weight, power consumption, and complexity compared to prior designs, making it more feasible to scale orbital data centers to a size that could significantly reduce the energy and water demands of terrestrial data centers. Each computing node is equipped with lightweight radiators for heat dissipation and solar panels that both

GRU Space, a new startup, has begun accepting reservations for a future Moon-based hotel, with ticket prices ranging from $250,000 to $1 million. However, these payments function more as unsecured deposits or investments rather than confirmed bookings, as no firm timeline exists for the project. Tentative test missions are planned for 2029 or 2030, with the company aiming to host guests by around 2032. The proposed hotel would use inflatable habitats similar to NASA and Bigelow Aerospace’s B330 designs, protected from lunar hazards and later shielded with lunar regolith bricks. Access to the hotel would rely on crewed lunar transport operated by third parties like SpaceX. While some technological aspects, such as inflatable habitats and regolith-based shielding, are grounded in existing research and past demonstrations, the overall feasibility faces significant challenges. Currently, there is no established Moon tourism industry, no routine crewed lunar missions, and no emergency rescue or support infrastructure on the Moon, including power,

Space Beyond, a startup founded by Ryan Mitchell—a former NASA and Blue Origin engineer—is launching an affordable "Ashes to Space" program scheduled for October 2027. The company plans to send up to 1,000 people’s cremated ashes into orbit aboard a CubeSat integrated on a SpaceX Falcon 9 rideshare mission. Unlike existing memorial spaceflight services that typically cost thousands, Space Beyond’s entry-level offering starts at $249, made possible by leveraging the cost efficiencies of rideshare launches and a lean, bootstrapped business model focused on accessibility rather than high profits. Due to weight constraints inherent in CubeSat launches, customers can only send about one gram of ashes each, allowing the company to accommodate many individuals per mission. The CubeSat will orbit in a sun-synchronous orbit approximately 550 kilometers above Earth for about five years before re-entering the atmosphere and burning up, symbolically ending the memorial. Customers will be able to track the satellite as it passes over their location

Researchers at New York University Abu Dhabi, in collaboration with Jilin University, have developed a novel type of "smart" organic molecular crystal capable of self-repairing damage even at extremely low temperatures, down to -196°C (-320°F), the boiling point of liquid nitrogen. This material, detailed in Nature Materials, not only restores its structural integrity after mechanical damage in freezing conditions but also recovers its ability to transmit light, making it suitable for flexible optical and electronic devices operating in harsh environments. The self-healing property arises from the crystal’s unique molecular structure, where molecules possess permanent dipole moments that enable mutual attraction and reformation. This discovery marks the first observation of self-healing in an organic crystal across such a wide temperature range, contrasting with previous self-healing materials like gels and polymers that fail under extreme cold. The durable and lightweight nature of these smart molecular crystals holds significant promise for space technology, where materials must withstand severe conditions and impacts from high-speed space debris.

A student-led team at Cornell University has successfully deployed the world’s first free-flying light sail in space, named Alpha CubeSat. Deployed from the International Space Station on January 13, this light sail is also the smallest ever deployed, weighing just 0.2 pounds (100 grams) and measuring about half a meter across. Unlike previous light sails, Alpha CubeSat’s sail detaches completely from its CubeSat carrier, becoming an independent spacecraft powered solely by the momentum of sunlight photons reflecting off its retroreflective polycarbonate surface. The sail unfolds near-instantaneously via a spring-loaded latch mechanism, a significant improvement over larger sails that take minutes to hours to deploy. The mission, supported by a NASA program for student-built spacecraft, highlights the advantages of CubeSats for experimental spaceflight due to their low cost and lightweight design. Alpha CubeSat carries tiny ChipSat computers that provide solar power, computing, sensors, and communication independently of the CubeSat. After initial contact issues,

The article explores how nuclear propulsion technologies influenced the early design of interstellar spacecraft, particularly during the Cold War era. With the realization that the Milky Way contains hundreds of billions of stars and potentially up to a trillion planets, scientists began seriously considering interstellar travel. Early spacecraft concepts from the mid-20th century were large, ambitious, and costly, but over time designs have shifted toward smaller, automated probes requiring minimal human intervention. The Cold War period (1950–1963) was pivotal, as breakthroughs in nuclear fission and fusion reactors spurred efforts by the U.S. and USSR to develop nuclear rocket propulsion systems. Three main categories of nuclear propulsion emerged: External Nuclear Rockets (ENRs), which use nuclear explosions outside the spacecraft to generate thrust but produce hazardous radiation; Internal Nuclear Rockets (INRs), which use a contained fission reactor to heat propellant or generate electricity but lack the power to escape the Solar System; and Fission-Fragment Rockets (FFRs), which use

China is conducting advanced experiments aboard its Tiangong space station to study the effects of microgravity on lithium-ion battery behavior, aiming to develop safer and more powerful batteries for space applications. Zhang Hongzhang, a professor specializing in advanced battery technologies from the Dalian Institute of Chemical Physics and China’s second civilian astronaut, is leading these tests during the Shenzhou-21 mission launched in October 2025. His research focuses on how microgravity influences key battery processes such as ion movement between electrodes, electrolyte chemical distribution, and the formation of lithium dendrites—needle-like structures that can reduce battery lifespan and pose safety risks. By leveraging the unique microgravity environment aboard Tiangong, Zhang’s experiments seek to isolate the impact of gravity on battery performance, which is difficult to study on Earth due to the interplay of gravitational and electric fields. The findings are expected to enhance the safety and efficiency of current lithium-ion batteries used in orbit and contribute to the development of next-generation batteries with higher energy density

The Vera C. Rubin Observatory, equipped with the world’s largest digital camera—the 3,200-megapixel LSST Camera—has detected the fastest-spinning asteroid larger than 500 meters ever observed. The asteroid, designated 2025 MN45, measures approximately 710 meters (0.4 miles) in diameter and completes a full rotation every 1.88 minutes. This rapid spin implies that 2025 MN45 possesses exceptionally high material strength, likely comparable to solid rock, which is unusual since most asteroids of this size are thought to be "rubble piles" composed of loosely bound debris. The discovery was part of a study led by Sarah Greenstreet and her team, who analyzed data collected during the Rubin Observatory’s early commissioning phase. Their findings, published in The Astrophysical Journal Letters, highlight how fast-spinning asteroids can offer valuable insights into the formation and composition of solar system bodies, as well as their collisional histories.

A novel collaboration between Scottish scientists and fashion designer Katie Tubbing has produced multi-layered textiles dyed with pigments derived from harmless bacteria, designed to visually indicate exposure to UV and cosmic radiation. These bacteria-based pigments fade predictably as radiation breaks down their molecular structure, creating a sustainable, low-tech, battery-free warning system. The fabric’s layered design allows different colors to fade at varying radiation thresholds, providing an immediate visual cue of cumulative exposure. This innovation aims to protect astronauts on lunar missions, assist medical workers monitoring radiation, and potentially inform everyday clothing that alerts wearers to harmful sunlight. To validate the fabric’s performance in space, a sample will be launched aboard a PocketQube satellite into low Earth orbit early next year, where onboard cameras will document color changes over time. If successful, a larger patch will be sent to the Moon in 2028 to study pigment degradation under lunar radiation, marking the first Scottish-built hardware on the lunar surface.

German researchers led by nuclear physicist Thomas Siegert at Julius Maximilian University of Würzburg have adapted space telescope technology to improve detection of radioactive contamination in dismantled nuclear power plants. Their project, scintLaCHARM, funded with nearly USD 2.3 million by the German Federal Ministry of Research, developed a novel method using scintillation detectors—lightweight crystals traditionally used in orbiting instruments—to map radiation more quickly, precisely, and efficiently than conventional semiconductor detectors. These conventional detectors require cooling to extremely low temperatures and scan only small areas slowly, making the decommissioning process lengthy, costly, and hazardous. The new cameras employ multiple scintillation crystals that light up upon gamma radiation exposure, allowing determination of radiation direction and energy through analysis of crystal interactions. This data, processed by supercomputers, generates detailed 3D images pinpointing contamination locations and types, enabling reliable separation of contaminated from uncontaminated materials. The technology benefits from collaboration with experts involved in NASA’s COSI gamma-ray

China’s experimental Shijian-21 and Shijian-25 satellites recently conducted a historic on-orbit refueling test in geosynchronous orbit (GEO), marking a potential strategic milestone. The two satellites, which docked around late June 2023 after several rendezvous and proximity operations, have now separated at an altitude of approximately 22,236 miles (35,786 km) above Earth’s equator. This maneuver likely signifies the completion of a successful refueling operation, although official confirmation from Chinese authorities remains absent. The Shijian-25 satellite, launched in January 2023, was confirmed by the Shanghai Academy of Spaceflight Technology to focus on testing on-orbit refueling and mission extension technologies in GEO. The significance of this test lies in its dual-use potential: on-orbit refueling is critical for future deep-space exploration missions, enabling spacecraft to extend their operational lifespans and travel farther, such as missions to the Moon and beyond.

The concept of space-based solar power, first proposed in 1968 by aerospace engineer Peter Glaser, envisions harvesting solar energy in space and beaming it to Earth to provide uninterrupted, weather-independent renewable energy. Despite decades of interest, operational space solar power stations remain unrealized due to significant technical and economic challenges. NASA’s 2024 report highlights key obstacles such as assembling large solar arrays in geostationary orbit, autonomous operation, and the high costs compared to terrestrial solar power, which require major technological advances to overcome. Nonetheless, the potential benefits are substantial, with studies suggesting space solar could supply up to 80% of Europe’s renewable energy needs and achieve energy densities ten times higher than Earth-based alternatives. Governments in China, the US, and Europe have shown growing support for advancing this technology. Currently, companies like Star Catcher and Aetherflux are pioneering more incremental approaches to make space solar power viable.

A weak spot in Earth’s magnetic field known as the South Atlantic Anomaly (SAA) is expanding and intensifying, posing increased risks to satellites and astronauts. Data collected over the past decade by the European Space Agency’s Swarm satellite constellation reveals that since 2014, the SAA has grown by an area roughly half the size of continental Europe and has weakened by 336 nanoteslas. This region’s magnetic field is less able to shield against harmful solar radiation, exposing satellites and crew aboard the International Space Station to higher levels of charged particles that can disrupt electronics and pose health risks. The changes in Earth’s magnetic field are linked to complex processes in the planet’s molten iron core and the shifting of the northern magnetic pole toward Siberia. While the SAA weakens and expands over the South Atlantic, a strong magnetic region over Siberia has grown both in size and intensity, increasing by 0.42 percent of Earth’s surface area and gaining 260 nanoteslas in strength

Researchers at the University of Illinois Urbana-Champaign have developed an innovative method to transform flat 3D-printed sheets into curved, strong satellite structures using a combination of 3D printing and frontal polymerization—a heat-triggered chemical reaction. This low-energy, scalable technique enables lightweight, flat components to be launched into space and then morph into complex 3D shapes such as satellite dishes, antennas, and other aerospace structures, potentially reducing launch costs and cargo space requirements. The process involves printing continuous carbon fiber composites partially cured with ultraviolet light, then activating the flat parts with a small heat pulse that triggers a self-propagating reaction to form the desired curved shapes. The team addressed the "inverse problem" of determining the 2D printing pattern needed to achieve specific 3D shapes, successfully creating configurations including a spiral cylinder, twisted strip, cone, saddle, and notably a parabolic dish ideal for satellite applications. Inspired by kirigami art, the parabolic dish design uses petal-like

The article "Sending Solar Panels to Space" discusses the concept of deploying solar panels in space as a means to generate clean energy more efficiently. Unlike Earth-based solar panels, which are limited by atmospheric interference and weather conditions, space-based solar panels could capture uninterrupted sunlight, potentially providing a more consistent and powerful energy source. The idea suggests that by placing solar panels in orbit, we could overcome the limitations posed by the Earth's atmosphere and weather variability, leading to a significant advancement in clean energy technology. However, the article does not provide detailed information on the technical challenges, costs, or current progress related to this concept, leaving some aspects unclear.

The article "The Physics of A Space Elevator" discusses the concept of a space elevator as a long-envisioned solution for affordable and reusable access to space, eliminating the costs and environmental impact associated with traditional single-use rockets. Despite its appeal, the article highlights that humanity has yet to realize this vision due to significant technical and material challenges. Key obstacles include the need for materials with extraordinary tensile strength to construct the elevator cable, which must extend from Earth's surface into space while supporting its own weight and withstanding environmental stresses. Current materials do not meet these stringent requirements, making the construction of a functional space elevator unfeasible with today's technology. The article implies that advances in material science and engineering are essential before this concept can move from dream to reality.

Elon Musk has publicly endorsed the concept of space-based solar radiation management (SRM) as a potential tool to combat global warming. SRM involves reflecting a portion of the Sun’s rays away from Earth to reduce global temperatures, and Musk suggested that a constellation of AI-powered satellites could make precise adjustments to the amount of solar energy reaching the planet. This idea, which merges climate science with aerospace engineering, has divided the scientific community due to its technical complexity and uncertain environmental impacts. While Musk’s position carries significant weight given SpaceX’s extensive satellite infrastructure, experts caution that deploying SRM at a planetary scale faces enormous technical, ethical, and geopolitical challenges. Potential risks include unpredictable disruptions to weather patterns and international conflicts over control of such technology. Although startups have begun experimenting with various geoengineering approaches, these remain largely theoretical and far from practical implementation. Musk’s involvement, however, signals growing interest in radical climate interventions as global temperatures continue to rise and traditional emissions reduction efforts fall short.

Researchers at ETH Zurich, led by Dr. Parth Chansoria, have successfully 3D printed human muscle tissue in microgravity conditions simulated via parabolic flights. This breakthrough addresses a major challenge in bioprinting on Earth, where gravity causes bio-inks—mixtures of living cells and carrier substances—to collapse or deform before solidifying, resulting in less accurate tissue structures. In weightlessness, the printed muscle fibers maintain their natural alignment and cell distribution, closely replicating human muscle tissue. This precision is critical for creating reliable tissue models for drug testing and disease study. To achieve this, the team developed a novel bioprinting system called G-FLight (Gravity-independent Filamented Light), capable of producing viable muscle constructs within seconds during short microgravity phases. The muscle samples printed in these conditions showed comparable cell viability and fiber density to those printed under normal gravity, with the added advantage of enabling long-term storage of cell-loaded bio-resins—an important factor for future space

UK engineers at the University of Surrey have developed a novel protective coating, termed a “cosmic veil,” designed to shield perovskite solar cells (PSCs) from the harsh radiation environment of space. This coating, made from propane-1,3-diammonium iodide (PDAI₂), stabilizes the fragile organic molecules within PSCs that are typically vulnerable to damage from proton irradiation and other space radiation sources such as galactic cosmic rays and solar energetic particles. By preventing these organic components from breaking down into gases that weaken the cells, the coating helps maintain the cells’ efficiency and structural integrity over long durations. Testing demonstrated that PSCs treated with this coating sustained significantly less efficiency loss and internal damage when exposed to radiation levels simulating over 20 years in low-Earth orbit. This breakthrough addresses a major limitation of PSCs in space applications, where durability and radiation tolerance are critical. While multi-junction III-V solar cells currently dominate space power systems due to their performance

NASA has developed a groundbreaking AI-driven technology called Dynamic Targeting, enabling satellites to autonomously analyze their surroundings and decide where to collect scientific data without human intervention. Demonstrated aboard the CubeSat CogniSAT-6, launched in March 2024, the system allows the satellite to tilt forward along its orbit, capture preview images, and process them in under 90 seconds to identify cloud-free areas. This capability helps avoid wasting time and resources imaging through clouds, a common obstacle for Earth-observing satellites, by selectively capturing only clear views. Dynamic Targeting mimics human interpretation by recognizing meaningful features such as clouds, fires, or storms in real time, then adjusting the satellite’s instruments accordingly. Future tests aim to reverse the approach by targeting clouds and rapidly evolving weather phenomena like deep convective ice storms, as well as thermal anomalies such as wildfires and volcanic eruptions. These applications rely on specialized onboard algorithms trained to detect specific patterns, enhancing the satellite’s responsiveness and adaptability. NASA en

A team of Japanese researchers from institutions including Tohoku University, JAXA, and Kyoto University has developed a novel copper-based shape memory alloy (Cu-Al-Mn) that retains its shape memory effect at extremely low temperatures down to -200°C (-328°F). This breakthrough addresses a significant limitation of existing shape memory alloys (SMAs), such as nickel-titanium (Ni-Ti), which lose functionality below -20°C. The new alloy is the first actuator material capable of delivering large mechanical work output in cryogenic conditions, making it suitable for applications in harsh environments like deep space and super-chilled hydrogen systems. To demonstrate its practical potential, the researchers created a mechanical heat switch using the Cu-Al-Mn alloy as an actuator, which operated flawlessly at -170°C by regulating heat flow through contact switching. This innovation paves the way for high-performance actuators in cryogenic environments, with promising uses in space telescope cooling systems and carbon-neutral hydrogen transport and storage technologies.

Researchers at the Niels Bohr Institute (NBI) at the University of Copenhagen have developed a novel tunable quantum sensing system that significantly improves measurement accuracy by overcoming noise limits inherent in conventional optical sensors. This tabletop device leverages large-scale entanglement by pairing a multi-photon light state with a large atomic spin ensemble, enabling frequency-dependent squeezing of light. This approach reduces quantum noise across a broad frequency range by dynamically adjusting the phase and amplitude of light, which traditional systems cannot achieve without large-scale infrastructure. The innovation addresses both back-action noise—disturbances caused by the measurement process—and detection noise, enhancing sensor sensitivity beyond the standard quantum limit. Unlike previous frequency-dependent squeezing applications that require extensive optical resonators (around 300 meters long), the NBI team’s compact system achieves similar performance on a tabletop scale. Potential applications include improved detection of time variations, acceleration, and magnetic fields, with significant implications for biomedical imaging such as enhancing MRI resolution for earlier neurological disorder diagnosis, as well

The article explores the hypothetical scenario of Earth rotating twice as fast, resulting in a 12-hour solar day instead of the current 24-hour day. While such a rapid rotation is unrealistic, considering this counterfactual helps physicists understand fundamental concepts about Earth's rotation and its effects. The distinction between a solar day (24 hours, based on the sun’s position) and a sidereal day (about 23 hours 56 minutes, based on Earth's full rotation relative to distant stars) is explained, highlighting how Earth's orbit around the sun affects the length of a day. One key implication of a shorter day is the change in centrifugal force experienced at the equator, making people feel lighter there compared to the poles. This difference in apparent weight arises because the faster rotation increases the outward centrifugal force, which partially counteracts gravity. The article connects this thought experiment to the concept of space elevators—tethers extending from Earth to geosynchronous orbit that could enable easier access to space without rockets.
