Have a research idea that could advance NASA science? 🔬
NASA plans to release ROSES-27 by January 2027, with over 50 research opportunities spanning astrophysics, Earth science, planetary science, heliophysics, space biology and more.
Start planning: go.nasa.gov/489ZKqw

Today, the calendar makes a right triangle, for the last time this century.
This Saturday is October 24, 2026.
Write it as 10/24/26 or 24/10/26, and the same beautiful relationship appears:
10² + 24² = 26²
100 + 576 = 676
But here’s what makes today special.
There are infinitely many Pythagorean triples. Only a handful fit our calendar.
Using the rule
month² + day² = (last two digits of the year)²,
the month cannot exceed 12, and the day cannot exceed 31. Those small limits leave exactly 12 qualifying dates in this century.
Today is the last.
The next will be March 4, 2105:
3² + 4² = 5²
That is a wait of more than 78 years.
An infinite family of triangles. Just twelve appearances on a century’s calendar.
Happy Pythagorean Triple Day.

Supersized heat waves used to be rare. No longer. A Reuters data-driven examination of global temperatures reveals the emergence of what we call heat storms. They now swarm the planet, upending life around the world. reut.rs/4zBUXtM

After more than 15 years in orbit, @NOAA will be deorbiting the Suomi NPP satellite starting on Dec. 1, 2026. This will be done by gradually lowering its orbit before it reenters Earth’s atmosphere over the South Pacific Ocean.
Suomi NPP was a pathfinding mission to demonstrate the capabilities of NOAA's JPSS constellation. The data provided by Suomi NPP are now operationally delivered by NOAA-20 and NOAA-21.

Vindicated in my thinking at the time that "The budget should increase by a factor of 10" is the funniest Decadal recommendation ever.
OIG Report On The NASA Decadal Survey Process
oig.nasa.gov/audits/nasas-ro…
Congress, NASEM, and NASA deeply value the decadal surveys. However, the OIG determined that the process, combined with the Agency’s hands-off approach, limits pathways for communication, engagement, and feedback. This, in turn, restricts opportunities for more tailored, realistic, and actionable surveys.
In addition, outside of NASEM’s 5-year midterm assessments, the OIG found that NASA does not track how the SMD divisions are implementing decadal survey recommendations. The Agency is also not fully accounting for costs associated with the survey process, including mission concept study expenditures and the time spent working on decadal survey tasks.
Lastly, NASA does not have consistent internal processes for supporting decadal survey development. Specifically, SMD lacks formal guidance, routine lessons learned, and sufficient resources to standardize common procedures and share best practices across the directorate. @NASA

The world’s leading seasonal forecast models have never shown California this wet, not even in 1997–98.
Europe’s Copernicus climate service (C3S) just released its October outlook, combining 10 seasonal forecast models from 9 weather agencies. The C3S average calls for 156% of normal precipitation statewide this Dec–Feb, the wettest California winter forecast these models have produced, wetter even than their reruns of the 1997–98 super El Niño.
Out of 454 total model members, only 8% show a drier-than-average Dec–Feb statewide, while about 13% are explicitly forecasting California’s wettest winter on record. A record-wet winter is now more likely than a dry one.
This far out, forecasts are about odds, not certainties. But 9 in 10 runs come in at or above normal, and even the driest 10% of runs average 88% of normal. The odds have never leaned this heavily toward an exceptionally wet winter, though a below-normal winter is still possible, but extremely unlikely.

Yes, it's true. RIP Hōlei Sea Arch.
The iconic Hōlei Sea Arch in Hawaiʻi Volcanoes National Park has collapsed into the Pacific Ocean, marking the latest transformation of the park’s remote and rugged coastline.
