On June 5, NASA ordered five astronauts into a docked Crew Dragon at 9:03 a.m. EDT while Russian cosmonauts prepared to cut into the ISS's leaking PrK tunnel — a structural problem seven years in the making that no patch has permanently solved.
NASA's X-59 reached Mach 1.1 at 43,400 feet on June 5 — the first supersonic flight of the QueSST program. Here's the wave physics behind the quiet boom, and why this flight matters for the future of overland supersonic travel.
NASA has announced the Artemis III crew for the first crewed lunar landing since Apollo 17 — targeting the south pole and its permanently shadowed water ice deposits.
Sentinel-6B's first validated altimetry data continues the longest unbroken sea level record in history. Sea level rise has nearly doubled in rate since 1993 — here's what the 33-year record now shows.
China's lunar program in 2025 is on track: Chang'e 7 heads for the Moon's south pole, Long March 10 nears its first flight, and 17 nations have joined the ILRS. Here's where it all stands.
Laser satellite communication transmits data 100× faster than radio with no spectrum allocation. Here's how free-space optical inter-satellite links work and what the Australia-Japan collaboration is achieving.
Sentinel-6B's Poseidon-4 SAR altimeter extends 30+ years of global sea level data. Here's how satellite radar altimetry actually works and why this Copernicus mission is irreplaceable for climate science.
Venturi's MONA LUNA is a European commercial lunar rover targeting the Moon's south pole before 2030. Here's the mission architecture, the technology challenges, and what it means for European space ambitions.
NASA's super pressure balloon completed a full Earth circumnavigation in 16 days at 33 km altitude. Here's the engineering that keeps a football-stadium balloon aloft for months without venting gas.
Arkadia Space's in-orbit green propellant test validates a non-toxic hydrazine replacement for small satellites. Here's how high-performance green propellants compare to hydrazine — and why the industry is finally switching.
Solar Orbiter captured the first-ever images of the Sun's south pole in 2025, revealing a chaotic magnetic field at solar maximum. Here's what the images show and why they matter for space weather forecasting.
Parker Solar Probe's closest-ever images reveal the solar corona in unprecedented detail — what WISPR captured at perihelion and how the spacecraft survives 1,400°C.
