The number 40,000 might not sound particularly dramatic, but it represents humanity's growing catalogue of near Earth asteroids, rocky remnants from the Solar System's violent birth that cross paths with our planet's orbit. We've come a long way since 1898, when astronomers discovered the first of these wanderers, an asteroid called Eros.

Earth's Wobble: An Overview of Precession
The Earth's axis of rotation is not fixed in space; instead, it undergoes a slow, continuous change in direction. This movement is commonly referred to as "Earth's wobble," or more formally, axial precession. This phenomenon affects long-term climate patterns and the location of the celestial poles over thousands of years.

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
In early October, the third interstellar object (ISO) to visit our Solar System (3I/ATLAS) made its closest flyby to Mars, coming within 30 million km (18.6 million mi) of the Red Planet. This placed it within view of several missions currently operating there, which are operated by three space agencies: NASA, the European Space Agency (ESA), and the China National Space Agency (CNSA). While the ESA released images taken by the Mars Express* and *ExoMars Trace Gas Orbiter (TGO), and China released images taken by the Tianwen-1 orbiter, NASA was unable to release any data due to the government shutdown.
Blue Origin to Build a "Super Heavy" Rocket to Compete with Starship
Blue Origin just achieved another impressive milestone with its new heavy-launch vehicle, the partially reusable New Glenn rocket. On Thursday, Nov. 13th, during what was only the second launch of the New Glenn (NG-2), Blue Origin launched a NASA payload destined for Mars. This was the ESCAPADE (Escape and Plasma Acceleration Dynamics Explorers) mission, a pair of twin satellites that will study how solar wind interacts with Mars’ magnetic environment and how this interaction drives atmospheric escape.
