Blocks of dry ice carve gullies on Martian dunes through explosive sublimation
Mysterious gullies carved into Martian sand dunes have long puzzled planetary scientists. Now, new experiments by Utrecht University Earth scientist Dr Lonneke Roelofs suggest they were dug not by flowing water or lifeforms, but by sliding blocks of solid carbon dioxide that explode and burrow as they sublimate under Martian conditions.
Roelofs replicated the process in a controlled "Mars Rocket Lab begins 21-mission campaign for Synspective with successful Electron launch
Rocket Lab has launched the first of 21 planned Electron missions for Japanese radar imaging company Synspective, successfully deploying the StriX-3 satellite to low Earth orbit on October 14. The mission, named "Owl New World," lifted off from Launch Complex 1 in Mahia, New Zealand, at 16:33 UTC.
The launch marked Rocket Lab's 15th mission of the year and its seventh for Synspective since PLD Space fast-tracks MIURA 5 and sharpens Europe leadership in space access
PLD Space says it has advanced its reusable MIURA 5 orbital launcher from concept to near-validation in just two years, crediting vertical integration, MIURA 1 heritage, and in-house manufacturing. The company targets completing 2025 with its first fully integrated MIURA 5 ready for final qualification.
MIURA 5 is progressing through subsystem qualification across engines, structures, avio K2 Space Corp, SpaceX ink Falcon 9 rocket deal for 2027 mission
Aerospace startup company K2 Space will team up with SpaceX to deploy a small number of K2 satellites into multiple levels of Earth's orbit.
On Tuesday, California-based K2 Space announced its new contract with Elon Musk's SpaceX to launch three K2 satellites on a Falcon 9 rocket for a 2027 mission dubbed "Trinity," which will lift three satellites into low, medium and geostationary tra Modular robots could both explore off-world and build infrastructure

Is there life on Terran V? Join the adventure to the fictional planet and find out what it takes to reach the farthest frontiers of deep space.
This video uses a fictional spacecraft and a fictional star system to illustrate a gravity assist manoeuvre – also known as a planetary flyby or swingby. The gravity assist is one of the most important techniques in deep-space navigation. By carefully passing close to a planet, a spacecraft can exchange orbital momentum with the much larger body. From the spacecraft’s perspective, this results in a change in trajectory and a significant
Light-driven control of topological structures unlocks new path for ultrafast memory
In a breakthrough uniting photonics and condensed matter physics, researchers have developed a new optical technique to precisely control topological solitons - including skyrmions and antiskyrmions - inside ferroelectric materials. The discovery could pave the way for next-generation ultrafast memory and logic devices.
The study, published in Physical Review B, was led by scientists from Google to invest $15 bn in India, build largest AI hub outside US
Google said Tuesday it will invest $15 billion in India over the next five years, as it announced a giant data centre and artificial intelligence base in the country.
"It is the largest AI hub that we are investing in anywhere outside of the US," Google Cloud CEO Thomas Kurian said at a ceremony in New Delhi.
