An alternative is for the automated spacecraft to assume that tracking is always available and to have the spacecraft take its data and return it accepting that some fraction of the time communication will in fact not be available. Science data would then go into the bit bucket. Since current spacecraft are complex and expensive, the latter solution is rarely used (intentionally!) today.

In addition an adequate staging EUS cannot be performed unless the original site of the resection can be identified by an endoscopic tattoo, residual tissue, or a postresection scar.
