The Japan Aerospace Exploration Agency (JAXA) has announced on its website that the agency has plans to put a Transformable Lunar Robot on the moon. In their announcement, they note that the goal of the robot deployment is to learn more about the surface of the moon as part of preparation for the deployment of a future crewed rover.

JAXA has made clear its aim to be part of establishing a permanent crewed presence on the moon, and as part of that, the agency has developed a lunar lander and is working on a rover. The lander, officially called the ispace lunar lander, has been designed to be a generic host for multiple entities. Customers planning to use the lander include the Canadian Space Agency and The Mohammed Bin Rashid Space Center. JAXA is developing a rover as well, which it plans to send to the moon in 2029. The lander will be launched aboard SpaceX rockets.

As part of their effort to develop a rover, JAXA has commissioned a team from the toy manufacturer, Tomy Company, Sony Corporation and Doshisha University to build a small lunar robot to test dust conditions on the moon. The design of the robot involves making use of transformable technology to save space in the lander—during launch it will be shaped like an 80 mm diameter ball (and will weigh just 250 g). After deployment on the moon, it will push itself into two halves with a connecting axle between them—the separated halves will then serve as wheels to allow the robot to move around on the surface.

Batteries and fuel cells often rely on a process known as ion diffusion to function. In ion diffusion, ionized atoms move through solid materials, similar to the process of water being absorbed by rice when cooked. Just like cooking rice, ion diffusion is incredibly temperature-dependent and requires high temperatures to happen fast.

This temperature dependence can be limiting, as the materials used in some systems like fuel cells need to withstand high temperatures sometimes in excess of 1000 degrees Celsius. In a new study, a team of researchers at MIT and the University of Muenster in Germany showed a new effect, where ion is enhanced while the material remains cold, by only exciting a select number of vibrations known as phonons. This new approach—which the team refers to as “ catalysis”—could lead to an entirely new field of research. Their work was published in Cell Reports Physical Science.

In the study, the research team used a to determine which vibrations actually caused ions to move during ion diffusion. Rather than increasing the temperature of the entire material, they increased the temperature of just those specific vibrations in a process they refer to as targeted phonon excitation.

SpaceX is already underway on building its first floating spaceport platform, and the plan is for it to start hosting launches as early as next year. SpaceX CEO Elon Musk shared those details on the progress of its build for Deimos, one of two converted oil rigs that SpaceX purchased earlier this year in order to transform them into floating launch and landing sites for its forthcoming Starship reusable rocket.

SpaceX’s purchase of the two rigs at the beginning of this year was for the creation of Deimos and Phobos, two floating spaceports named after the moons of Mars. They’ll act as offshore staging grounds for Starship launch activities, and the name is appropriate because the eventual plan is to have Starship provide transport for both people and goods to and from the red planet.

Ocean spaceport Deimos is under construction for launch next year https://twitter.com/kendall_dirks/status/1398640498223587334
