The first stage of Rocket Factory Augsburg's first orbital launcher was destroyed in a fireball during a test-firing Monday evening at a spaceport in Scotland, the company said.

The German launch startup aimed to send its first rocket into space later this year and appeared to be running ahead of several competitors in Europe's commercial launch industry that are also developing rockets to deploy small satellites in orbit.

Within the last few months, Rocket Factory Augsburg (RFA) delivered all three stages of its first rocket, named RFA One, to its launch site at SaxaVord Spaceport, located on Unst, one of the Shetland Islands and the northernmost inhabited island in the United Kingdom. The company is based in Augsburg, Germany.

On the day before Christmas last year, a Falcon 9 rocket launched from California and put two spy satellites into low-Earth orbit for the armed forces of Germany, which are collectively called the Bundeswehr.

Initially, the mission appeared successful. The German satellite manufacturer, OHB, declared that the two satellites were "safely in orbit." The addition of the two SARah satellites completed a next-generation constellation of three reconnaissance satellites, the company said.

However, six months later, the two satellites have yet to become operational. According to the German publication Der Spiegel, the antennas on the satellites cannot be unfolded. Engineers with OHB have tried to resolve the issue by resetting the flight software, performing maneuvers to vibrate or shake the antennas loose, and more to no avail.
