China debuts a new medium-lift rocket. China’s new Long March 12 rocket made a successful inaugural flight Saturday, placing two experimental satellites into orbit and testing uprated, higher-thrust engines that will allow a larger Chinese launcher in development to send astronauts to the Moon. The Long March 12 is the newest member of China’s Long March rocket family, which has been flying since China launched its first satellite into orbit in 1970, Ars reports.
Rocket likely to be used for megaconstellation deployment … Like all of China’s other existing rockets, the Long March 12 configuration that flew Saturday is fully disposable. At the Zhuhai Airshow earlier this month, China’s largest rocket company displayed another version of the Long March 12 with a reusable first stage but with scant design details. The Long March 12 is powered by four kerosene-fueled YF-100K engines on its first stage, generating more than 1.1 million pounds, or 5,000 kilonewtons, of thrust at full throttle. These engines are upgraded, higher-thrust versions of the YF-100 engines used on several other types of Long March rockets. (submitted by EllPeaTea and Ken the Bin)
Falcon 9 rocket reaches some remarkable milestones. About 10 days ago, SpaceX launched a batch of Starlink v2-mini satellites from Kennedy Space Center in Florida on a Falcon 9 rocket, marking the 400th successful mission by the Falcon 9 rocket. Additionally, it was the Falcon program’s 375th booster recovery, according to SpaceX. Finally, with this mission, the company shattered its record for turnaround time from the landing of a booster to its launch to 13 days and 12 hours, down from 21 days, Ars reports.
A rapidly reusable shuttle … All told, in November, SpaceX launched 16 Falcon 9 rockets. The previous record for monthly launches by the Falcon 9 rocket was 14. SpaceX is on pace to launch 135 or more Falcon 9 and Falcon Heavy missions this year. That is a meaningful number, because over the course of the three decades it flew into orbit, NASA’s space shuttle flew 135 missions. The space shuttle was a significantly more complex vehicle, and unlike the Falcon 9 rocket, humans flew aboard it during every mission. However, there is some historical significance in the fact that the Falcon rocket may fly as many missions in a single year as the space shuttle did during its lifetime.
