US Space Force to Establish Orbital Filling Stations for Satellite Refueling
The US Space Force is looking to establish orbital filling stations for its satellites, aiming to extend their mission life by refueling them in orbit. Northrop Grumman’s Passive Refueling Module (PRM) has been selected by the Space Force as the preferred model to set the standard for refueling satellites in orbit within the Space Systems Command (SSC). Satellites, with their high construction and launch costs, require propellant to function. Despite efforts to maximize their lifespan, the need for propellant remains a limiting factor. Many satellites require propellant to maintain their orientation, adjust orbits, and ensure operational efficiency. As a result, after a few years, satellites can become obsolete due to fuel depletion, despite being in good condition. To address this issue, companies like Northrop Grumman have been developing in-orbit servicing modules. These robotic spacecraft can dock with satellites running low on fuel, providing them with supplemental propulsion, new power sources, and even conducting minor repairs. The Space Force is particularly interested in this technology, as military satellites require frequent orbital shifts for various operational needs, making propulsion a critical asset. Refueling satellites in orbit presents challenges, requiring standardization to ensure compatibility between servicing modules and visiting satellites. This need for standardization has been a longstanding issue in space exploration, dating back to the Apollo Soyuz mission in 1975, which required a common docking mechanism for US and USSR spacecraft. The development of orbital filling stations and standardized refueling technology holds promise for extending the operational lifespan of satellites, offering a cost-effective solution for maintaining and enhancing satellite capabilities in orbit.

Invasive Earthworm Species Threaten Native Ecosystems in North America
A new study warns of the threat posed by at least 70 imported earthworm species in North America. These earthworms, largely overlooked, are disrupting native ecosystems and biodiversity. The research highlights the need to better understand and manage these invaders, which have been brought to the continent from Asia, Europe, South America, and Africa since the late 1800s.
New Insights into the Mysterious Gap in the Size Distribution of Super-Earths
Recent simulations have shed light on the deviation of some planets from their original birthplaces, providing insights into the relatively low number of exoplanets with sizes around two Earth radii, also known as the radius valley or gap. Remo Burn, an exoplanet researcher at the Max Planck Institute for Astronomy (MPIA) in Heidelberg, and lead author of the article published in Nature Astronomy, highlighted the shortage of exoplanets with sizes around two Earth radii, a phenomenon discovered six years ago through a reanalysis of data from the Kepler space telescope. These findings open new avenues for understanding the dynamics of planetary systems and the factors influencing the size distribution of exoplanets.

Study Links Pregnant Women’s Gut Microbiota to Changes in Immune System
A recent study reveals the significant links between a pregnant woman’s gut microbiota and changes in her immune system, shedding light on potential implications for maternal and fetal health. The study’s key findings highlight the unique gut microbiota composition and cytokine profile in pregnant women, suggesting the microbiota’s role in modulating immune responses during pregnancy. However, the study emphasizes the need for further research to clarify these findings due to its small sample size and the observational nature of the study.
