    Venus Might Have Tectonic Activity After All
    One of the big differences between Venus and Earth is the lack of plate tectonics. While Earth's continents float on tectonic platesconstantly reshaping our worldVenus was previously thought to remain locked in a largely static crust with only occasional volcanic hotspots. But everything we thought we knew might be wrong! Researchers examining 30-year-old NASA Magellan spacecraft images have spotted what appears to be the smoking gun of tectonic activity on our hellish sister planet, potentially rewriting planetary science as we know it.

    There's No Simple Origin Story for Long Gamma Ray Bursts
    Gamma-ray bursts (GRBs) are the most powerful phenomena in the Universe. First detected during the Cold War, these events beam a tremendous amount of high-energy light our way in a short period of time. They come in two types: short GRBs that last for less than two seconds and long GRBs that last for minutes. Both types have mysterious origins. Short GRBs could be caused by the collisions of neutron stars or perhaps the powerful flares of a magnetar. Observations of long GRBs suggest they are caused by a powerful supernova called a hypernova, where a massive star collapses to become a black hole. But a new study suggests that the origins of long GRBs are more diverse.

    Methane is the Key to Understanding Titan
    Saturn's moon Titan is the only other body in the Solar System with weather similar to Earth's. The large moon has a thick, nitrogen-rich atmosphere like Earth's, liquid on its surface, and a precipitation cycle. But instead of water, the surface liquid and the precipitation cycle are mainly based on methane.

    Using Shape Memory Alloys To Navigate Underground Spaces
    Shape Memory Alloy (SMA) is becoming increasingly common in space exploration applications. It has primarily been used in deployable structures, such as antenna booms or solar sail deployment. However, it also has a use case nearer the ground of whatever planet, moon, or asteroid it finds itself near. A new paper by Shufeng Tang and their colleagues at the Inner Mongolia University of Technology uses SMA to solve a problem in an area near and dear to space explorers' heartssmall space flexible robotics.

    Why Don't Titan's Seas Have Deltas?
    Titan, the largest moon of Saturn, looks more Earth-like on its surface than any other place in the Solar System. With its thick atmosphere and liquid methane rain, it has lakes, rivers, sand dunes and seas. But appearances can be deceiving and in other ways, Titan is in fact a very alien world. One baffling difference, recently discovered, is that Titan's rivers do not seem to form deltas when they reach the sea.

    Martian Resource Potential and Challenges for Future Human Activities
    What steps can be taken to enhance in-situ resource utilization (ISRU) for future astronauts on Mars? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as an international team of researchers investigated the reasons, benefits, and challenges of conducting ISRU on Mars. This study has the potential to help astronauts, scientists, engineers, and mission planners develop new methods for enhancing the survivability of future Mars astronauts while also maximizing mission success.

    Microbes are Evolving that Thrive in Spacecraft Cleanrooms
    Spacecraft are expensive and intricately engineered machines designed to perform complex missions in harsh space environments. They're costly and require a long time to design and build. Due to their uniqueness and high value, and the need to keep them sterilized, they're assembled in cleanrooms that limit the amount of dust and microbes. New research shows that microbes are adapting to these clean rooms and learning how to thrive in them.

    Redpoint raises $650M 3 years after its last big early-stage fund
    Redpoint Ventures, a San Francisco-based firm that is about a quarter of a century old, has raised a $650 million tenth early-stage, according to a regulatory filing. Redpoints new fund matches the size of its prior fund, which was raised just under three years ago. In a market where many venture firms are decreasing their []
