German startup Rocket Factory Augsburg (RFA) just put the brakes on its first launch.While testing its RFA One rocket on the launch pad at the U.K.'s SaxaVord Spaceport on the Shetland Islands in Scotland, the company found "an issue with the vehicle that requires further investigation," RFA wrote on X on Wednesday (July 28). Previously, the launch had been expected to happen in August or September, but RFA did not disclose a new launch date.RFA did not disclose the nature of the issue, but said it would de-stack the staged rocket and that it would provide more details as the investigation continues. The situation means that the U.K. will need to wait at least a few more weeks to attempt its first-ever vertical launch from the region, amid global constraints in launch capacity and calls for increased European spaceflight autonomy.RFA One, a smaller rocket designed to launch smaller satellites, is a three-stage rocket that will eventually include a reusable first stage in an effort to push down cost and to increase launch cadence. It will target a range of orbits, with examples including geosynchronous (where a satellite can constantly look at one area of the Earth), polar (allowing satellites to scan the whole Earth, as the planet orbits underneath) or sun-synchronous (which gives consistent lighting conditions.)It's common for new rockets to encounter issues during development, including in later stages such as integrated pad testing or even during the first launch, because spaceflight is inherently hard. That said, there is more pressure on startup launching companies than ever to achieve their goals quickly, for commercial and defense reasons.
