China lands a reusable rocket for the first time: Why this matters for the space race | Explained News

China on Friday successfully landed a reusable rocket for the first time — a milestone for the country’s space programme that will challenge American companies’ dominance in the technology. The Long March 10B rocket — which can carry a payload of up to 16 metric tons to low Earth orbit — lifted off from the Wenchang Commercial Space Launch Site in Hainan, Southern China around noon (local time). Low Earth orbit is a region between 160 km and 2,000 km above the Earth. Six minutes after liftoff, the rocket’s booster — the part that houses the engine and provides the initial thrust — separated from its upper stage and began a controlled descent to a floating platform on the sea. There, it was caught by a net. Before China, only Elon Musk’s SpaceX and Jeff Bezos’s Blue Origin demonstrated the ability to launch and land rockets. So how does China’s technology differ from previous reusable rockets and what strategic implications does this step have? We explain. The mechanics of re-entry  All rockets lift off in …

Preliminary Examination: Current events of national and international importance Mains Examination: General Studies-III: Science and Technology- developments and their applications and effects in everyday life. What’s the ongoing story: In a rare failure, India’s main rocket PSLV developed problems a few minutes after take-off and failed to place earth observation satellite EOS-09 into the intended orbit in an early morning launch on Sunday. Key Points to Ponder: — What are the Earth observation satellites? Story continues below this ad — What are the different types of launch vehicles of ISRO? — What is the difference between PSLV and GSLV? — What are the various stages of rockets? — Learn about the important ISRO’s missions – Aditya L1, Chandrayaan 4, Chandrayaan 5, Shukrayaan-1 — What do you understand by space debris? Key Takeaways: — “Today’s 101st launch was attempted. PSLV-C61 performance was normal till second stage. Due to an observation in the third stage, the mission could not be accomplished,” ISRO said. — This was the 101st mission launched by ISRO, and the 63rd one using …
