n a study that closes a long-standing knowledge gap in fundamental science, researchers Boerge Hemmerling and Stephen Kane at the University of California, Riverside, have successfully measured the electric dipole moment of aluminum monochloride (AlCl), a simple yet scientifically crucial diatomic molecule. Their results have implications for quantum technologies, astrophysics, and planetary science.

Using a variety of microscopic analysis techniques not available when the Apollo astronauts first returned samples from the moon, researchers have been able to take a close look at the microscopic mineral deposits on the outside of lunar beads. 

A new Focus emphasizes the growing threat posed by space debris accumulating in Earth’s orbit and reviews potential robotic solutions to address this problem. Jake Abbott points out that there are nearly 30,000 human-made objects at risk of colliding with functional satellites or spacecraft in orbit, which could lead to a chain reaction with catastrophic global consequences. The author suggests that soft robotics approaches and contactless methods that can manipulate, capture, or remove debris are promising avenues for moving towards a cleaner space environment. “The robotics community has much to offer in creating solutions to these crucial problems,” Abbott writes. “Given that the loss of Earth orbit would upend life as we know it, those of us who can contribute solutions to the problem of space debris should prioritize doing so.”
