Scientists have found a way to track invisible solar storms by watching what they block out: the constant rain of cosmic rays. The Threat: Coronal Mass Ejections (CMEs) are massive clouds of solar plasma that can disrupt satellites and power grids.

Spaceflight doesn't just weaken bones. New MRI scans reveal that microgravity physically reshapes the human brain, compressing it against the skull. On Earth, gravity anchors our brains. In space, that anchor is gone. The Study: Comparing astronauts to bed-rest volunteers, researchers found that spaceflight causes the brain to float upward within the skull.

NASA's newest telescope isn't looking for new planets. It's looking at the stars they orbit, trying to fix a "flickering candle" problem that threatens to ruin our best data. Studying an exoplanet's atmosphere is like holding a glass of red wine up to a candle. You analyze the light filtering through the liquid to judge its quality.

Huge rockets like Starship and New Glenn are finally flying. For astronomers, this means escaping the "Origami Trap" of costly, folding telescopes. Imagine listening to a piano recital, but you can only hear one octave. That's astronomy from Earth.

With the ISS retiring, Russia plans to build a successor. The strategy? Detach its old modules and start over—but critics warn the hardware may be too toxic to reuse. The original plan (OPSEK) to separate the Russian segment was abandoned in 2017 but has been revived due to geopolitical tensions. The Plan: When ISS retires (c. 2030), Russia intends to detach its modules—Zarya, Zvezda, Nauka, etc.—to form the core of the new Russian Orbital Station (ROS).

Getting into a car is easy. Getting into the Orion spacecraft for a trip to the moon requires a specialized "pit crew." Meet the Artemis II Closeout Team. When astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen arrive at the launch pad, five people will be waiting for them. These are the last humans the crew will see before leaving Earth. Led by Taylor Hose, the team acts like a Formula 1 pit crew, but with much higher stakes.

Shipping cement to the Moon is impossibly expensive. To land massive rockets like Starship, we must build pads from local dust—but a new study reveals a dangerous paradox in the design. Why build a pad? You can't just land in the dirt. A rocket plume kicks up high-velocity rocks that can destroy nearby habitats or damage the rocket itself.

Just like your cellphone switches networks when you travel, NASA's new PExT technology proves spacecraft can "roam" between government and commercial satellites. It’s a game-changer. Imagine if your phone only worked on one specific tower in your hometown. Drive 20 miles away, and you have zero signal. That was essentially the reality for early space missions. They were locked into specific government networks.

Millions of objects careen around Earth at 15,000 mph. Without a cleanup plan, we risk trapping ourselves on our own planet. On November 5, 2025, the threat became real. The Shenzhou-20 crew capsule, docked at the Tiangong station, was struck. A piece of debris smaller than 1mm—roughly a grain of sand—hit the window at 17,000 mph. The result? A crack deep enough to ground the capsule and force a rescue mission.

Every launch leaves a mark. Scientists now argue that the principles of Reduce, Reuse, and Recycle must apply to the final frontier before it becomes a graveyard. Transitioning to a circular economy requires more than just better rockets. It requires data. The authors highlight the need for AI systems to track spacecraft health and predict failures before they happen.

On the evening of November 28, 2025, a new era in space science began as Mauve—the first privately funded satellite dedicated to studying stellar flares—launched aboard a SpaceX Falcon 9 rocket from California. Developed by London-based Blue Skies Space, the compact, microwave-sized observatory will peer into the ultraviolet universe to reveal how stars erupt and how those explosions affect nearby exoplanets.

As humanity races toward the Moon, Mars, and beyond, a quiet revolution is unfolding in spacecraft propulsion—not in the engines themselves, but in the intelligence that designs and controls them. Artificial intelligence, particularly reinforcement learning, is transforming how we develop and operate advanced propulsion systems, from nuclear thermal rockets to compact fusion reactors.
