The communications system had picked up a faint subspace signal from several parsecs distant.

"The landing party on the surface is receiving a tight-beam subspace signal, Captain."

Seventy-two days after the event began, the first weak subspace signal arrived.

"I am still detecting the subspace signal on our emergency bands."

"The star system that was generating a subspace signal," he said, swiftly recalling details.

Apparently, an energy field around the planet she'd crashed on shifted the subspace signals through time.

"Could you at least send a subspace signal back to Earth so another ship can come out here and get us?"

Our subspace signal can't get through this energy field.

That still put him a few light-hours away, but the subspace signals were much stronger now.

He said, "Have you enough information now to send your subspace signal?"
