San Antonio TX (SPX) Apr 15, 2025 NASA’s Lucy spacecraft is 6 days and less than 50 million miles (80 million km) away from its second close encounter with an asteroid; this time, the small main belt asteroid Donaldjohanson. This upcoming event represents a comprehensive “dress rehearsal” for Lucy’s main mission over the next decade: the exploration of multiple Trojan asteroids that share Jupiter’s orbit around the Sun. Lucy’s first asteroid encounter – a flyby of the tiny main belt asteroid Dinkinesh and its satellite, Selam, on Nov. 1, 2023 – provided the team with an opportunity for a systems test that they will be building on during the upcoming flyby. Lucy’s closest approach to Donaldjohanson will occur at 1:51pm EDT on April 20, at a distance of 596 miles (960 km). About 30 minutes before closest approach, Lucy will orient itself to track the asteroid, during which its high-gain antenna will turn away from Earth, suspending communication. Guided by its terminal tracking system, Lucy will autonomously ro

DOI: 10.1002/adma.202414096 The development of increasingly sophisticated sensors can facilitate the advancement of various technologies, including robots, security systems, virtual reality (VR) equipment and sophisticated prosthetics. Multimodal tactile sensors, which can pick up different types of touch-related information (e.g., pressure, texture and type of material), are among the most promising for applications that can benefit from the artificial replication of the human sense of touch. While electronics engineers have created a wide range of highly sensitive tactile sensors over the past few decades, the accura

Hardware and system architecture specifications. Credit: Science Robotics (2025). DOI: 10.1126/scirobotics.adp9905 A team of cyber-systems researchers, engineers, optical specialists and roboticists at Zhejiang University, in China, has developed a navigation system for quadcopter drones that gives them the ability to carry out precise flight maneuvers autonomously. As reported in the journal Science Robotics, the group developed a multi-pronged system that allows quadcopter drones to carry out complex aerobatic maneuvers autonomously, in a safe manner, both indoors and outdoors. It would be advantageous if drones were able to carry out tasks autonomously without human intervention. It would allow for flying tasks beyond the sight of a remote pilot, for example. It would also greatly reduce the cost of other tasks, such as delivering packages. Because of that, researchers have been working to make drones smarter. Just two years ago, a team at the University of Zurich developed what they described as a highly
