SpaceX warns of dangerous Chinese launch. China’s recent deployment of nine satellites occurred dangerously close to a Starlink satellite, SpaceX’s vice president of Starlink engineering said. Michael Nicolls wrote in a December 12 social media post that there was a 200-meter close approach between a satellite launched December 10 on a Chinese Kinetica-1 rocket and SpaceX’s Starlink-6079 spacecraft at 560 kilometers (348 miles) altitude, Aviation Week and Space Technology reports. “Most of the risk of operating in space comes from the lack of coordination between satellite operators—this needs to change,” Nicolls wrote.
Blaming the customer… The company in charge of the Kinetica-1 rocket, CAS Space, responded to Nicolls’ post on X saying it would “work on identifying the exact details and provide assistance.” In a follow-up post on December 13, CAS Space said the close call, if confirmed, occurred nearly 48 hours after the satellite separated from the Kinetica-1 rocket, by which time the launch mission had long concluded. “CAS Space will coordinate with satellite operators to proceed.”
A South Korean startup is ready to fly. Innospace, a South Korean space startup, will launch its independently developed commercial rocket, Hanbit-Nano, as soon as Friday, the Maeil Business Newspaper reports. The rocket will lift off from the Alcântara Space Center in Brazil. The small launcher will attempt to deliver eight small payloads, including five deployable satellites, into low-Earth orbit. The launch was delayed two days to allow time for technicians to replace components of the first stage oxidizer supply cooling system.
Hybrid propulsion… This will be the first launch of Innospace’s Hanbit-Nano rocket. The launcher has two stages and stands 71 feet (21.7 meters) tall with a diameter of 4.6 feet (1.4 meters). Hanbit-Nano is a true micro-launcher, capable of placing up to 200 pounds (90 kilograms) of payload mass into Sun-synchronous orbit. It has a unique design, with hybrid engines consuming a mix of paraffin as the fuel and liquid oxygen as the oxidizer.
Ten years since a milestone in rocketry. On December 21, 2015, SpaceX launched the Orbcomm-2 mission on an upgraded version of its Falcon 9 rocket. That night, just days before Christmas, the company successfully landed the first stage for the first time. Ars has reprinted a slightly condensed chapter from the book Reentry, authored by Senior Space Editor Eric Berger and published in 2024. The chapter begins in June 2015 with the failure of a Falcon 9 rocket during launch of a resupply mission to the International Space Station and ends with a vivid behind-the-scenes recounting of the historic first landing of a Falcon 9 booster to close out the year.
