Rocket Report: SpaceX’s expansion at Vandenberg; India’s PSLV fails in flight

Summary

SES makes a booking with Impulse Space. SES, owner of the world's largest fleet of geostationary satellites, plans to use Impulse Space’s Helios kick stage to take advantage of lower-cost, low-Earth-orbit (LEO) launch vehicles and get its satellites quickly into higher orbits, Aviation Week & Space Technology reports. SES hopes the combination will break a traditional launch conundrum for operators of medium-Earth-orbit (MEO) and geostationary orbit (GEO). These operators often must make a trade-off between a lower-cost launch that puts them farther from their satellite's final orbit, or a more expensive launch that can expedite their satellite's entry into service. A matter of hours ... On Thursday, SES and Impulse Space announced a multi-launch agreement to use the methane-fueled Helios kick stage. "The first mission, currently planned for 2027, will feature a dedicated deployment from a medium-lift launcher in LEO, followed by Helios transferring the 4-ton-class payload directly to GEO within eight hours of launch," Impulse said in a statement. Typically, this transit to GEO takes several weeks to several months, depending on the satellite's propulsion system. "Today, we’re not only partnering with Impulse to bring our satellites faster to orbit, but this will also allow us to extend their lifetime and accelerate service delivery to our customers," said Adel Al-Saleh, CEO of SES. "We're proud to become Helios' first dedicated commercial mission." Unpacking China's spaceflight patches. There's a fascinating set of new patches Chinese officials released for a series of launches with top-secret satellites over the last two months, Ars reports. These four patches depict Buddhist gods with a sense of artistry and sharp colors that stand apart from China's previous spaceflight emblems, and perhaps—or perhaps not—they can tell us something about the nature of the missions they represent. The missions launched so-called TJS satellites toward geostationary orbit, where th...
