Galactic Alarm (Perry Rhodan No. 3)

187 pp. We find the Arkonide ship that was destroyed in "The Radiant Dome" managed to send off a distress signal to the universe. Perry Rhodan and friends have only had a few days to get used to the situation that they created when they landed in the Gobi desert, and now must use all their wits and new-found Arkonide knowledge to start preparing Earth for what may be possible rescue missions - or worse.
