About a decade ago, I encountered a novel or a novella that I cannot locate.
The setting was Earth, about one century into the future. I remember vampires and a mesh of satellites around the Earth that were burning up in the atmosphere. This motivated a mission to deep space to find the intelligence responsible for the satellites.
Most of the novel focused on the crew of the mission — I recall that they were not "standard" humans. They had modifications to their minds and bodies, possibly for the mission.
At the time, I had gone on a binge, reading many short stories, novellas, and novels in quick succession. I fear that I might be combining several stories into one, especially the vampires and the deep-space first-contact mission, and so I am fully prepared for an answer of the form, "No such story exists."
Any assistance would be greatly appreciated.
