Zero-boil-off tank experiments to enable long-duration space exploration
Posted by Genevieve Klien in categories: space travel, sustainability
Do we have enough fuel to get to our destination? This is probably one of the first questions that comes to mind whenever your family gets ready to embark on a road trip. If the trip is long, you will need to visit gas stations along your route to refuel during your travel.
NASA is grappling with similar issues as it gets ready to embark on a sustainable mission back to the moon and plans future missions to Mars. But while your car’s fuel is gasoline, which can be safely and indefinitely stored as a liquid in the car’s gas tank, spacecraft fuels are volatile cryogenic liquid propellants that must be maintained at extremely low temperatures and guarded from environmental heat leaks into the spacecraft’s propellant tank.
And while there is already an established network of commercial gas stations in place to make refueling your car a cinch, there are no cryogenic refueling stations or depots at the moon or on the way to Mars.

New Realistic Computer Model will Help Robots Collect Moon Dust
Posted by Natalie Chan in categories: robotics/AI, space travel
A new computer model mimics Moon dust so well that it could lead to smoother and safer Lunar robot teleoperations. The tool, developed by researchers at the University of Bristol and based at the Bristol Robotics Laboratory, could be used to train astronauts ahead of Lunar missions. Working with their industry partner, Thales Alenia Space in the UK, who has specific interest in creating working robotic systems for space applications, the team investigated a virtual version of regolith, another name for Moon dust.
Lunar regolith is of particular interest for the upcoming Lunar exploration missions planned over the next decade. From it, scientists can potentially extract valuable resources such as oxygen, rocket fuel or construction materials, to support a long-term presence on the Moon. To collect regolith, remotely operated robots emerge as a practical choice due to their lower risks and costs compared to human spaceflight.
However, operating robots over these large distances introduces large delays into the system, which make them more difficult to control. Now that the team know this simulation behaves similarly to reality, they can use it to mirror operating a robot on the Moon. This approach allows operators to control the robot without delays, providing a smoother and more efficient experience.

The Butlerian Jihad: Frank Herbert’s Warning Against A.I. | Dune Lore Explained
Posted by Dan Breeden in categories: education, robotics/AI, space travel
An exploration of Frank Herbert’s implicit and explicit warnings against the unmitigated advancement and dependence on AI (Artificial Intelligence), while also examining how these fundamental concerns, leading to AI’s prohibition, consistently resonate throughout the series. One of its less explored, but equally compelling, elements is its commentary on the rise of artificial intelligence. Dune is set in the far future taking place in an interstellar empire that is devoid of thinking machines after a universal ban against computing technology that is made in the likeness of a human mind. The reasons behind this prohibition not only serve as a caution against the perils of artificial intelligence, but they also underscore broader warnings present throughout Herbert’s Dune books.

Unlocking the Secrets Behind Galaxy Formation
Posted by Saúl Morales Rodriguéz in categories: cosmology, space travel, supercomputing
Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international research team, led by researchers in Lund, has spent a hundred million computer hours over eight years trying to correct these.
The last decade has seen major advances in computer simulations that can realistically calculate how galaxies form. These cosmological simulations are crucial to our understanding of where galaxies, stars, and planets come from. However, the predictions from such models are affected by limitations in the resolution of the simulations, as well as assumptions about a number of factors, such as how stars live and die and the evolution of the interstellar medium.

Elon Musk Says Starship Will Spin for Artificial Gravity
Posted by Genevieve Klien in categories: Elon Musk, space travel
SpaceX is gearing up for its third attempt to get its massive Starship spacecraft into orbit. In a recent update, the company hinted at a March 14 launch “pending regulatory approval.”
Meanwhile, SpaceX CEO Elon Musk is already thinking many steps ahead, envisioning what’ll be like to travel on board the spacecraft all the way to Mars.
“Starship will have a small spin on the way to Mars,” Musk replied after Id Software founder John Carmack suggested SpaceX should try to spin its Dragon astronaut shuttle to test out spin gravity. “Even a tiny gravity vector is better than none.”
