China's Chang'e-4 lander touched down on the Moon's far side in January 2019. Using instruments including ground-penetrating radar, the mission collected subsurface profiles near its landing site. A team writing in the Journal of Geophysical Research: Planets reports the top roughly 130 feet (about 40 metres) of the surface is layered—alternating dust, soil and broken rock—and that a buried impact crater lies within those layers.

India’s space agency ISRO plans to launch Aditya-L1, a satellite designed to observe the Sun, on 2 September. The spacecraft will travel to the Sun–Earth Lagrange Point 1, about 1.5 million kilometres from Earth, where it can keep the Sun continuously in view. The mission follows India’s successful Chandrayaan-3 Moon landing and represents a major step in the country’s expanding space programme, aimed at improving understanding of solar activity.

A YouGov–Cambridge Globalism Project survey asked people in many Western countries whether more should be done to improve women’s rights at home. In several nations a clear majority or near-majority said yes. Italians topped the list at 62%, followed by Spaniards at 60%, Hungarians at 57% and Swedes at 56%. Other countries where roughly half of respondents expressed concern included Poland, France, Canada, Australia and Greece.

As clocks move forward each spring across the northern hemisphere, debates over daylight saving time continue in several Western European countries. YouGov's Eurotrack survey asked people in Britain, Denmark, France, Germany, Italy, Spain and Sweden whether their country should stop switching clocks twice a year. Responses vary widely: 75% of Germans want to end the practice, while Italy is the only country where a majority (56%) prefers to keep changing the clocks. Britain and Spain were narrowly divided on the question.
