Modeling the Fight Between Charged Lunar Dust and Spacecraft Coatings

Understanding how exactly lunar dust sticks to surfaces is going to be important once we start having a long-term sustainable presence on the Moon. Dust on the Moon is notoriously sticky and damaging to equipment, as well as being hazardous to astronaut’s health. While there has been plenty of studies into lunar dust and its implications, we still lack a model that can effectively describe the precise physical mechanisms the dust uses to adhere to surfaces. A paper released last year from Yue Feng of the Beijing Institute of Technology and their colleagues showcases a model that could be used to understand how lunar dust sticks to spacecraft - and what we can do about it.

Finding 40,000 Asteroids Before They Find Us

Astronomers have just catalogued the 40,000th near Earth asteroid, a milestone that marks humanity's transformation from passive targets to active defenders of our planet. These space rocks, ranging from house sized boulders to some the size of mountains, follow orbits that bring them uncomfortably close to Earth. Each discovery adds another piece to our planetary defence puzzle, though current surveys have found only about 30 percent of the mid sized asteroids that could still cause regional devastation if they struck our world.

The Box vs The Bulldozer: The Story of Two Space Gas Stations

Using in-situ propellant has been a central pillar of the plan to explore much of the solar system. The logic is simple - the less mass (especially in the form of propellant) we have to take out of Earth’s gravity well, the less expensive, and therefore more plausible, the missions requiring that propellant will be. However, a new paper from Donald Rapp, the a former Division Chief Technologist at NASA’s JPL and a Co-Investigator of the successful MOXIE project on Mars, argues that, despite the allure of creating our own fuel on the Moon, it might not be worth it to develop the systems to do so. Mars, on the other hand, is a different story.

NASA Finally Releases Images of 3I/ATLAS Taken by Its Missions at Mars

Two orbiters and a rover captured images of the interstellar object — from the closest location any of the agency’s spacecraft may get — that could reveal new details.

Blue Origin to Build a "Super Heavy" Rocket to Compete with Starship

Blue Origin announced a series of upgrades to New Glenn designed to increase payload performance and launch cadence, while enhancing reliability. The enhancements span propulsion, structures, avionics, reusability, and recovery operations, and will be phased into upcoming New Glenn missions beginning with NG-3.

Is the Universe Infinite?

The surface of the Earth is finite. We can measure it. If it was expanding, then its size would grow with time. And once again, good ol’ Earth helps us understand what the universe might be doing beyond our observable horizon.

AI Cracks Galaxy Simulation

Scientists have achieved a breakthrough that seemed impossible just months ago, they have simulated our entire Milky Way galaxy down to each of its 100 billion individual stars. By combining artificial intelligence with supercomputer power, researchers created a model that captures everything from galactic arms to the explosive deaths of individual stars, completing in days what would have taken conventional simulations 36 years. This fusion of AI and physics represents a significant shift in how we model complex systems, with implications reaching far beyond astronomy.
