Signals - Part 1

A month ago, Starfleet picked up an unusual alien signal emanating from the Seku system, deep inside the Carina Nebula within the Shackleton Expanse. The runabout Yukon was initially dispatched to investigate, but the crew failed to report and is presumed lost. Starfleet has asked the USS Christopher Pike to investigate the source of the signal and locate the missing runabout.
