The Milky Way's galactic center should be home to many pulsars, but for some reason, we can't find them. New research identified a candidate pulsar very near the MW's center. If it can be confirmed, it's a chance to test General Relativity.

Ground Teams Stop Flow of Liquid Hydrogen During Artemis II Wet Dress Rehearsal
This past weekend, ground crews at the Kennedy Space Center replaced a filter in the ground support equipment used for propellant loading. This filter was suspected of reducing the flow of liquid hydrogen into the Core Stage during the wet dress rehearsal of the *Artemis II* rocket on Feb. 12th. The test provided the engineers with enough data to prepare for a second wet dress rehearsal, which NASA is targeting for Thursday, Feb. 19th. This test will put the launch team and supporting teams through a full range of operations.
Io: Jupiter's Volcanic Moon
Io is the innermost of the four Galilean moons orbiting Jupiter, distinguished as the most volcanically active world in the Solar System. Its extreme geological activity is a direct result of the immense tidal forces exerted by Jupiter, Europa, and Ganymede.

New Lunar Samples Challenge the "Late Heavy Bombardment"
Results are coming out from the samples returned by China’s Chang’e-6 sample return mission to the far side of the Moon. They offer our first close-up look at the geology and history of the far side, and a recent paper published in Science Advances from researchers at the Chinese Academy of Sciences has very interesting insights about the impact history of the Moon itself, and even some for the solar system at large.

River deltas are sinking faster than the sea is rising
Earth’s river deltas, home to about 5% of the global population and some of the world’s major cities, are experiencing subsidence, which exacerbates the risks from sea-level rise. The Copernicus Sentinel-1 mission has captured a decade's worth of data showing land sinking faster than previously thought.
How Mars' Toxic Soil Actually Makes Stronger Bricks
Using local resources will be key to any mission to either the Moon or Mars - in large part because of how expensive it is to bring those resources up from Earth to our newest outposts. But Mars in particular has one local resource that has long been thought of as a negative - perchlorates. These chemicals, which are toxic to almost all life, make up between 0.5-1% of Martian soil, and have long been thought to be a hindrance rather than a help to our colonization efforts for the new planet. But a new paper from researchers at the Indian Institute of Science and the University of Florida shows that, when making the bricks that will build the outpost, perchlorates actually help.
The Artemis 1 moon mission had a heat shield issue. Here’s why NASA doesn’t think it will happen again on Artemis 2
The Orion capsule's heat shield had issues during the uncrewed Artemis 1 moon mission in late 2022. Here are the steps NASA has taken to prevent them from recurring on Artemis 2.
