Hensen who'd been half asleep, tured from the long day at the convention, woke up. He needed a moment to realise what's going on. "Uh oh..."  He said, when he understood your clipped version. It was still a good hour until you'd reach the planet's atmospere. "Answer them?" He asked. "Maybe they just want directions." He didn't sound very convincing. "Or maybe they just wanna letbus know our lights are broken?" You could prepare a distress signal. If this were bad, maybe someone was close enough to answer. You were hailed again.
