A Road Map to Truly Sustainable Water Systems in Space
Future astronauts need efficient, durable, and trustworthy closed-loop systems to provide water for missions lasting months to years.
From Measurements to Solar Wind Model Initial Conditions
A new method shows how solar wind measurements at Earth can be used to define initial conditions for solar wind models to reduce their need for solar magnetic maps and decrease their uncertainty.
Primordial Impact May Explain Why the Moon Is Asymmetrical
Analysis of surface samples from the Chang’e-6 mission suggests that an asteroid may have vaporized parts of the lunar mantle, suppressing volcanic activity on the farside of the Moon.
Discovering Venus on Iceland
Scientists trekked across Icelandic lava flows that served as stand-ins for Venus’s volcanic landscapes, testing tools and methods the upcoming VERITAS mission will use when it reaches the planet.
ALMA’s New View of the Solar System
High-resolution radio observations link the chemistry of local moons and comets to the birth environments of distant exoplanets.
Successful Liquid Lake Conditions in a Cold Martian Paleoclimate
Simulations from a new lake model explain how liquid water could have been maintained over Mars in a cold climate, thus resolving a critical scientific gap in our understanding of Mars’ early history.
Science Escapes Largest Cuts in Latest Budget Bills
Today, top appropriators in the U.S. Senate and House of Representatives released a three-bill appropriations package for fiscal year 2026 (FY26) that largely rejects drastic cuts to federal science budgets that President Trump proposed last year.
Sunspot Drawings Illuminate 400 Years of Solar Activity
A new computational framework is helping scientists sift through centuries of scientific illustration of the Sun’s spotty surface.
Could Future Mars Habitats Be Made of Ice?
Models suggest that clear ice, sourced and distilled on Mars, could offer a feasible alternative for building stable off-world structures.
Astronauts Could Live in Structures Made from Moon Rocks
Scientists are testing “mooncrete,” a concrete analogue made from lunar regolith, as a potential material to build structures on the Moon.
