In its latest shakeup to the Commercial Crew Program, NASA announced on Monday it has reduced the number of missions Boeing is required to fly to the International Space Station and changing the next flight from a crew mission to a cargo mission.
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.
Spain’s offer to host the powerful observatory, mired in funding obstacles and local controversies, might promise a new path forward.
This is not good news for the future of our planet.
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.

The clock is ticking! Applications for the ESA Student Internship Programme 2026 close on 30 November. This is your chance to take your first step into the world of space.
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 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.
A SpaceX Falcon 9 rocket, flying for the first time, launched 28 Starlink satellites into low Earth orbit from Vandenberg Space Force Base in California on Sunday, Nov. 23, 2025.

According to the leading theory of how the Earth-Moon system formed (the Giant Impact Hypothesis), a Mars-sized object (named Theia) collided with a proto-Earth 4.5 billion years ago. This turned both objects into molten lava, which eventually coalesced and cooled to form the Earth and Moon. Over time, the Moon migrated outward, eventually reaching its current, tidally locked orbit around Earth, where one side is permanently facing us. For decades, scientists have debated where Theia may have originated, whether it formed in the inner or outer Solar System.
