Space manipulators play an important role in the on-orbit services and planetary surface operation whose reliability is a key issue. In the extreme environment of space, space manipulators are susceptible to a variety of unknown disturbances. Since it is difficult for the manipulator to be repaired immediately, once it fails, it will mean that it cannot complete the mission as expected, which may cause serious losses and dangers. How to have a resilient guarantee, i.e., the manipulator’s ability to resiliently recover and continue to complete tasks, in failure or disturbance is the core capability of its future development. The motion planning unit is used as the computing terminal of the manipulator’s joint motion trajectory. Compared with traditional motion planning, learning-based motion planning has gradually become a hot spot in current research. However, no matter what kind of research ideas, the single robotic manipulator is studied as an independent agent, making it unable to provide sufficient flexibility under conditions such as external force disturbance, observation noise, and mechanical failure.

New evidence from the gravitational-wave event GW230814 shows that when two black holes merge, the horizon area of the resulting black hole is very likely greater than the sum of the horizon areas of the two progenitors. An independent analysis by the Purple Mountain Observatory team finds a significance level up to about 4.1σ, supporting the classic black-hole “area law” originally proposed by Stephen Hawking and further reinforcing general relativity in the highly dynamical, strong-field merger regime.

Based on six years data from high energy particle detectors developed by Institute of High Energy Physics, CAS, onboard the China Seismo-Electromagnetic Satellite (CSES), the scientists analyze comprehensively the evolution characteristics of the geomagnetic field and high-energy protons in the South Atlantic Anomaly (SAA) from 2019 to 2024. The results show that both the magnetic field minimum and the proton flux center of the SAA drift northwestward, while the overall area of the SAA exhibits a shrinking trend. In addition, the spatiotemporal evolution of the SAA shows a certain correlation with solar activity.This marks the capability of China's autonomous and controllable high-quality satellite data to conduct precise and comprehensive monitoring of the space environment, significantly enhancing the country's space exploration capabilities.

Our solar system is racing through space faster than current models predict – as shown by a new study from Bielefeld University. The surprising findings challenge fundamental assumptions of cosmology.

Engineers at UC Davis have invented a device that can generate mechanical power at night by linking the natural warmth around us to the cold depths of space. The invention could be used, for example, to ventilate greenhouses or other buildings.

Scientists from New York University Abu Dhabi (NYUAD) have uncovered new evidence that water once flowed beneath the surface of Mars, revealing that the planet may have remained habitable for life much longer than previously thought.

Researchers at the University of Illinois Urbana-Champaign have developed a new method to 3D-print flat composite structures on Earth that can later morph into curved shapes in space using a small thermal trigger. By combining continuous-fiber 3D printing with a resin that undergoes frontal polymerization, the team can transform lightweight, flat materials into complex 3D geometries—such as cones or satellite dishes—without bulky curing ovens or pre-shaped molds. The innovation, supported by the Air Force Research Laboratory and published in Additive Manufacturing, could significantly reduce launch weight and cost for space missions.
