NASA's Techno-Wizardry Grants The Perseverance Rover Greater Autonomy February 20, 2026
When the Perseverance rover was sent to Mars, it was largely dedicated to astrobiology. It's driving around an ancient paleolake, Jezero Crater, looking for evidence of past life. But the rover mission is also a testbed for greater autonomous operations. Now, NASA has given the inquisitive rover a way to better navigate the Martian surface […]
Researchers Examine How We Could Achieve Sustainable Water Systems for Space February 20, 2026
If humans want to live in space, whether on spacecraft or the surface of Mars, one of the first problems to solve is that of water for drinking, hygiene, and life-sustaining plants. Even bringing water to the International Space Station (ISS) in low Earth orbit costs on the order of tens of thousands of dollars. […]
The Optical Engineering Required to Photograph an Earth Twin February 20, 2026
More and more papers are coming out about the upcoming Habitable Worlds Observatory (HWO). As the telescope moves from theory to practice (and physical manifestation), various working groups are discovering, defining, and designing their way to the world’s next major exoplanet observatory. A new paper from researchers at NASA Goddard Space Flight Center adds another […]
Searching Out Missing Links in Galaxy Evolution February 20, 2026
How do galaxies evolve? When did they start forming? Those are questions astronomers and cosmologists are working to answer. The standard path includes early bright starforming activity, a middle age, and then a quiescent old age where they stop making stars. That changes if the galaxy happens to collide with another one, because that spurs […]
Why Cosmic ‘Dark Matter’ Is Living On Borrowed Time February 20, 2026
A plethora of newly discovered baryonic (or normal) dark matter signals the first step toward the end of dark matter theory. Or so say the authors of a new paper just accepted by the journal Physical Review D.
