How CADRE Passed Its Autonomy Testing

By Andy Tomaswick April 29, 2025
Getting missions to land successfully on the Moon has been difficult. Recent missions, such as IM-1 and IM-2, which the private company Intuitive Machines completed, have been qualified successes at best, with both landers settling at unintended angles and breaking parts of them off along the way. Such experiences offer excellent learning opportunities, though, and NASA is confident that a third time might be a charm for a flawless mission. There will be a lot riding on IM-3, the third Commercial Lunar Payload Services (CLPS) mission, including a set of rovers and ground station for a NASA experiment called the Cooperative Autonomous Distribution Robotic Exploration (CADRE), which recently passed its Verification and Validation (V&V) test for one of it's most essential parts. This software architecture handles tasks for each rover and binds them into a cohesive whole.

Vesta: Not Quite a Planet, Not Quite an Asteroid

By Evan Gough April 29, 2025
As the second-largest object in the main asteroid belt, Vesta attracts a healthy amount of scientific interest. While smaller asteroids in the belt are considered fragments of collisions, scientists think Vesta and the other three large objects in the belt are likely primordial and have survived for billions of years. They believe that Vesta was on its way to becoming a planet and that the Solar System's rocky planets likely began as protoplanets just like it. But new research is casting doubt on that conclusion.

Environmental Factors for Humans Standing on Titan

By Laurence Tognetti, MSc April 28, 2025
What will a human experience while standing on the surface of Saturn’s largest moon, Titan, even with the protection of a pressurized spacesuit? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as William O’Hara, who is the Executive Director of Explore Titan investigated what physical attributes a human will experience when standing on Titan’s surface. This study has the potential to help scientists, engineers, mission planners, and the public better understand the risks associated with sending humans to far-off worlds for long periods of time and how to develop technologies to mitigate these risks.

Star birth is a process hidden inside dense crèches of gas and dust. Yet, if you know what to look for, you can see the products of this essential cosmic process across the sky. The Circinus West molecular cloud is a starbirth crèche some 2,500 light-years away. It boasts everything from dark nebulae to protostellar objects and newborn stars to the faint ghosts of stars that have already died.

Walking Moon Robots Possibly More Reliable than Lunar Rovers

By Laurence Tognetti, MSc April 28, 2025
How can walking robots deliver more efficient in-situ robotic exploration on the Moon compared to other types of robots? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers from the University of Southern California (USC) discussed the benefits of using legged robots for lunar exploration regarding gait speed (walking speed). This study has the potential to help engineers, scientists, mission planners, and astronauts develop novel robotic designs to conduct more efficient science and mission objectives on future Moon surface missions.

The Moon is a Constant Source of Minimoons

By Mark Thompson April 28, 2025
Earth has a number of companions in space; of course the Moon is the most well known but there are a host of smaller objects that visit us, complete a few orbits then head off again. A team of astronomers have detected four objects like this and have performed spectroscopic analyses on them. They found that their surface composition is similar to eh Moon suggesting that it’s a major source of these temporary satellites instead of the asteroid belt.

A Huge Molecular Cloud Found Close to the Solar System

By Mark Thompson April 28, 2025
The Orion Nebula is a fabulous example of a vast cloud of electrically charged gas which is emitting bright radiation. If the atoms in the gas are cool enough though, they can form giant molecular clouds that obscure light, these are known as dark nebula. A team of astronomers have now found an enormous cloud of molecular hydrogen in our own cosmic backyard just 300 light years away. The cloud contains 3,400 times the mass of the Sun and if we could see it, it would stretch nearly 40 times the width of the Moon across the sky.

How Do Robots Feel In Space?

By Andy Tomaswick April 28, 2025
How do robots feel in space? This is both a practical and possibly an existential question. Still, today, we'll focus on the practical side by looking at a review paper from Hadi Jahanshahi and Zheng Zhu of York University in Canada that discusses different tactile sensor types and their advantages and disadvantages for use in space.

Can Ion Engines Use Water as a Propellant?

By Evan Gough April 28, 2025
Ion drives are renowned for their efficiency. They're extremely efficient compared to chemical rockets, so they're preferred for deep space missions where propellant supplies are critical. New research shows how they could run on simple water, making them even more efficient.
