NASA Rewrites How It Picks Missions While the Hardware Keeps Flying

Compete on science first

NASA's Science Mission Directorate is overhauling how missions get selected, and the pitch is simple: compete on the science first. Under Competition Model 2.0, Astro-Probes, New Frontiers, and Discovery missions move to a new accelerated two-step competition that removes roughly half of the material currently required in an Announcement of Opportunity response. The selection timeline for those classes drops from 35 months to about 19.5 months, a cut of up to 45 percent. Smaller classes, including SMEX, Missions of Opportunity, Earth Venture, hosted payloads, and ride shares, move to a single-step competition with a smaller review team and virtual site visits, taking the time to final selection from about 32 months to about 19 months. m:…6345

NASA Administrator Jared Isaacman empowered the directorate to make the change, and the agency will explain it at a virtual Science Town Hall on October 26, 2026. The reasoning is that faster selection gets science to orbit sooner and reduces the proposal-writing tax on researchers. Mission and implementation teams will also be expected to adopt industry best practices and emerging commercial capabilities, a signal that NASA wants its science missions to look more like the commercial space economy. m:…6345

Faster, with teeth

Speed is only half the model. NASA says breaches of cost and schedule control thresholds will carry real consequences up to and including mission termination, a notably blunt line for an agency whose flagship missions have historically absorbed overruns. At the same time, NASA Centers will lead work to eliminate unnecessary competition and keep critical skills thriving, with work directed at Goddard and JPL to encourage collaboration rather than internal rivalry. m:…6345

The hardware doesn't wait

While the bureaucracy accelerates, the engines keep firing. NASA test-fired developmental RS-25 engine No. 10001 on October 21, 2026, at the Fred Haise Test Stand at Stennis Space Center near Bay St. Louis, Mississippi. Test teams fired the engine for 500 seconds, the same duration RS-25 engines fire during launch of the Space Launch System rocket, in support of future Artemis missions. m:…0553

On Mars, Perseverance reached an odometer reading of 45.22 kilometers on Sol 2006, October 11, 2026, setting a new record for the farthest distance driven on another celestial body. Aboard the International Space Station, astronaut and Expedition 75 flight engineer Jessica Watkins worked inside the Kibo module's Life Science Glovebox on the InSPA-Auxilium Bioprinter investigation, mixing living cell samples with bioink and filling a special cartridge to advance 3D bioprinting in microgravity. And NASA is developing the CASALS instrument, which blends machine learning with ultra-compact lidar to adaptively sweep large swaths of Earth's surface, addressing the enormous gaps between the narrow measurement lines of today's orbital lasers. The through-line is a program trying to move faster at every altitude. m:…3476 m:…8839 m:…8915

Ninety years in

The Jet Propulsion Laboratory is marking its 90th anniversary, a useful reminder of what the new model is trying to preserve. JPL began on October 31, 1936, when Caltech graduate students and enthusiasts started rocket-propulsion tests in Pasadena's Arroyo Seco; ninety years later it is managed by Caltech for NASA and is looking ahead to interstellar probes, lunar drones, and helicopters on Mars. The anniversary lands in the same week NASA told the science community that selection will get faster and overruns will get punished. For JPL, the next 90 years may be decided as much by the competition model as by the propulsion lab. m:…2629
