Could Comets have Delivered the Building Blocks of Life to “Ocean Worlds” like Europa, Enceladus, and Titan too?
Throughout Earth’s history, the planet’s surface has been regularly impacted by comets, meteors, and the occasional large asteroid. While these events were often destructive, sometimes to the point of triggering a mass extinction, they may have also played an important role in the emergence of life on Earth. This is especially true of the Hadean Era (ca. 4.1 to 3.8 billion years ago) and the Late Heavy Bombardment, when Earth and other planets in the inner Solar System were impacted by a disproportionately high number of asteroids and comets.
There’s More Water Inside Planets Than We Thought
When you walk across your lawn or down the street, you move on the surface of a surprisingly layered world. Some of those layers are rock, others are molten. A surprising amount of water is mixed into those layers, as well. It turns out that most planets have more of it “deep down” than we imagined.
Why Did Copernicus Reject Geocentrism?
Popular science history paints a picture of the Greek geocentric model dominating astronomical thought beginning around the 3rd century BCE, and being the favored model for ~1,500 years. Then, suddenly (it suggests), astronomical thought was overhauled at the birth of the Renaissance by brilliant astronomers such as Copernicus, Kepler, and Galileo, all of whom rejected placing the Earth at the center of the cosmos.

China Will Launch its Mars Sample Return Mission in 2028
While NASA’s Mars Sample Return mission has experienced a setback, China is still moving forward with their plans to bring home a piece of the Red Planet. This week, officials from the China National Space Administration (CNSA) announced their sample return mission, called Tianwen-3, will blast off for Mars in 2028. It will land on the surface, retrieve a sample, and then take off again, docking with a return vehicle in orbit. They also announced another mission, Tianwen-4 will head off to Jupiter in 2030 as well as unveiling a conceptual plan for China’s first mission to test defenses against a near-Earth asteroid.

Artemis III Landing Sites Identified Using Mapping and Algorithm Techniques
Where would be the most ideal landing site for the Artemis III crew in SpaceX’s Human Landing System (HLS)? This is what a recent study submitted to Acta Astronautica hopes to address as an international team of scientists investigated plausible landing sites within the lunar south pole region, which comes after NASA selected 13 candidate landing regions in August 2022 and holds the potential to enable new methods in determining landing sites for future missions, as well.
