New Glenn Isn't Racing to a Second Launch — It's Racing to a Launch Cadence

Here's a story that sounds almost mundane until you notice what it reveals: NASA's long-planned missions to Venus looked headed for cancellation, and now, according to Ars Technica…

Look up tonight and you can find Europa yourself — a faint pinprick lined up with Jupiter's three other Galilean moons, as last week's NASA Astronomy Picture of the Day showed when…

SpaceX flies Falcon 9 more than twice a week. In the same stretch, the booster launching this week's Space Development Agency mission will be making its sixth flight, landing itsel…

A Hacker News-sourced report making the rounds this week claims NASA has officially canceled the Mars Sample Return mission, citing budget overruns north of $11 billion and unmanag…

The case for lunar water ice has been building for decades — orbital spectrometers, impact plume analysis, neutron detectors — and the scientific consensus has hardened considerabl…

The acquisition document is unusually candid. When the Space Force's Commercial Space Office posted its award notice for "Starshield Custom Fleet Aviation Services" on August 25, t…

The Orion capsule carrying Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen hit Earth's atmosphere at close to 25,000 miles per hour. That's the number that gets quot…

The most important thing to understand about JWST's exoplanet science is the gap between what the telescope actually measures and what the headlines say it found. That gap is not a…

Last week, Northrop Grumman announced it would take the hardware it built for the lunar Gateway and land it on the Moon instead. The Canadian Space Agency made a similar pivot. Nei…

SpaceX's 13th full-scale Starship test flight ended with something the program had never managed before: a vehicle floating intact in the Indian Ocean, heat shield largely intact,…

The standard story of cosmic evolution goes something like this: the universe began in chaos, and order emerged slowly. Early galaxies were supposed to be messy, turbulent, still-a…

The headline version of Artemis 3 sounds almost normal now: NASA has a crew, a rocket, and a lander contractor. What the headline skips is that the lander itself exists in at least…

The booster failure on Starship's twelfth flight got most of the headlines. Eight Raptor 3 engines failing during the boostback burn, Booster 19 hitting the Gulf of Mexico at 1,450…

Three months ago, NASA Administrator Jared Isaacman stood at a podium and effectively canceled the Lunar Gateway. The "Ignition" event in March reoriented NASA's human spaceflight…

The molecule at the center of the most exciting exoplanet story of the past two years is called dimethyl sulfide. On Earth, it is produced almost exclusively by marine phytoplankto…

Six weeks ago, a Blue Origin New Glenn rocket exploded during a routine engine test at Cape Canaveral, destroying the vehicle and damaging the company's only launchpad. NASA respon…

SpaceX engineers deliberately broke their own heat shield on Flight 12. They removed a single tile before launch to see what would happen to the tiles around it when superheated pl…

Three years ago, NASA's Human Landing System looked like a model for how to run a commercial space program. Fixed-price contracts, milestone-based payments, two competing providers…

The James Webb Space Telescope has done something genuinely strange this week: it produced a weather forecast for a planet 690 light-years away. Cloudy mornings, clear evenings, wi…
