Swift Gets a Second Chance: How Commercial Servicing Is Saving NASA's Gamma-Ray Observatory
After 22 years in orbit, Swift faces imminent reentry from solar-driven decay. Katalyst Space's LINK robotic spacecraft will perform NASA's first commercial orbital rescue, boosting the aging but productive observatory to a stable orbit.

Asteroid 2026 JH2's Surprise Close Approach Exposes Detection Gaps in Planetary Defense
A 62-foot asteroid discovered just days before its closest approach demonstrates how near-Earth objects can slip past detection systems—and why autonomous surveys matter for planetary safety.

Katalyst LINK Spacecraft Integrated for Swift Observatory Rescue Mission
NASA's aging Swift Observatory faces imminent orbital reentry after decaying from 600km to 400km altitude. Katalyst Space's LINK robotic servicing spacecraft, integrated onto a Pegasus XL rocket, launches in late June to grip the telescope with lidar-guided arms and boost it back to operational orbit using ion thrusters.

Combat Surgeon, Record-Setter, Next: Army's Col. Rubio Named to Artemis III Earth Orbit Test Crew
Col. Frank Rubio — who shattered the U.S. record for longest single spaceflight — has been named to the 2027 Artemis III crew alongside ESA astronaut Luca Parmitano, in a mission that will test lunar lander docking in Earth orbit as the final dress rehearsal before the Moon.

The CNO Cycle: How Massive Stars Burn Hydrogen Differently Than the Sun
The Sun fuses hydrogen through the proton-proton chain. Stars more than twice as massive use a completely different nuclear pathway — one that uses carbon, nitrogen, and oxygen as catalysts and burns hotter, faster, and far more violently.

ExoMars Rosalind Franklin Rover: Still Alive, Still Going to Mars
ESA's ExoMars rover survived the loss of its Russian Roscosmos partnership and is being rebuilt for a European launch. If it gets to Mars, it will carry a drill no other mission has ever attempted.

ESA's Hera Mission Is About to Rewrite What We Know About Asteroid Deflection
NASA's DART proved we can move an asteroid. Now ESA's Hera spacecraft is arriving at Didymos to find out exactly what happened — and whether planetary defense is ready for a real threat.

The Upper Stage Problem: Why Reusable Second Stages Are Harder Than They Look
Recovering and reusing first stages was the revolution. But upper stages — which must survive orbital velocities and reentry — are a fundamentally harder problem, and the industry's three main bets are taking very different approaches.

VIPER Is Cancelled. Here's Why NASA's Ice-Hunting Rover Mattered.
NASA cancelled the VIPER rover in 2024 after costs ballooned and schedules slipped. The science it was supposed to do — characterizing water ice at the lunar south pole — still needs to be done before Artemis astronauts go there.

Military Space
Anti-satellite weapons are real, tested, and leaving debris clouds that threaten everyone
China, Russia, the US, and India have all tested direct-ascent anti-satellite missiles. The debris those tests create persists for decades. The tension between military necessity and orbital sustainability is becoming one of the defining strategic problems of the 2020s.
