China to launch Shenzhou-23 to Tiangong with first Hong Kong taikonaut, starting an overdue crew rotation China is set to launch Shenzhou-23 on Sunday from Jiuquan Satellite Launch Centre, sending three astronauts—Zhu Yangzhu, Zhang Zhiyuan and Lai Ka-ying—to Tiangong. The mission will relieve an overdue crew and could mark the start of China’s first year-long stay in orbit, with Lai becoming Hong Kong’s first astronaut on a Chinese space station flight.

Mars fungi research points to bioprocessing regolith into fertile growing media for early settlements A study on “Mars fungi” explores how Earth microbes could be used to make Martian regolith more suitable for growing food crops. The concept centers on using fungal action to condition the soil substrate so it can support a first self-sustaining harvest in a settlement scenario.

SpaceX conducts successful Starship V3 pre-IPO test, deploying mock satellites before Super Heavy booster breakup SpaceX says its upgraded Starship V3—paired with the Super Heavy booster—successfully deployed mock satellites and returned to Earth largely intact during a pre-IPO test. The booster, however, spun out of control and broke apart over the Gulf of Mexico, despite some engine outages. The company frames the flight as a key step toward future Moon and Mars missions.

NASA to Compete Jet Propulsion Laboratory (JPL) Management Contract Under Broader Agency Realignment NASA said it will compete the next contract to manage and operate its federally funded research and development center (FFRDC) at Jet Propulsion Laboratory in Southern California, positioning JPL’s oversight for a potential reset within a wider NASA restructuring. The move is framed as strengthening accountability and value for taxpayers.
