Oort Cloud Expeditions
China and the United States are both very interested in acquiring a mini black hole of their own. Only 2098 D2 is within practical range of optimized spacecraft built with current technology; reaching the next nearest target would take about 200 years.
Hawking Industries (in partnership with the ESA), China’s MAST, and the Gypsy Angels Collective have all dispatched long-range fusion- or antimatter-powered deep space operations vehicles to rendezvous with the object and establish a research station. Most of these vessels have fueled-to-empty mass ratios of 10:1 or more, allowing them to reach round-trip velocities of 250-350 mps.
The expeditions are expected to reach 2098 D2 in 9-11 years. They and their masters are currently negotiating protocols for sharing their research, while planning for what might happen if cooperation breaks down. None of the explorers admit to being armed, but all likely are. The situation is complicated because the body in question is small enough that the Revised Outer Space Treaty actually allows it to be claimed.
NASA and USAGs have not yet launched a mission, due to bureaucratic infighting over its control. However, Nanodynamics is also working on getting the Starswarm project back to operational status, as it could reach either 2098 D2 or one of the farther primordial black holes. If it works, it could get there much faster, perhaps within a year, but technical issues, especially regarding braking the probes, remain to be resolved.
