Rocket Report: China launches with no advance warning; Europe’s drone ship

Here is a 188 word summary of the news article: This week saw several updates to satellite mega-constellations. SpaceX launched more Starlink satellites, further expanding its internet network. Amazon's Project Kuiper also added more satellites to its planned constellation. Additionally, the US military conducted launches to boost its satellite communications capabilities. Meanwhile, the European Space Agency (ESA) is developing a reusable drone ship to autonomously retrieve spent rocket stages from the ocean. This could enable more frequent rocket launches by reducing the time and cost of recovering boosters. Notably, China conducted a surprise rocket launch this week, without providing advance warning. This appears to be part of China's efforts to rapidly build up its space capabilities. The lack of prior notification raised concerns, as it could pose risks to other space activities. Overall, the past week saw continued progress in the expansion of satellite mega-constellations by major players, as well as developments in reusable launch technology and China's secretive space program.
