Despite difficult mass and volumetric constraints, the Prometheus team was able to establish that a small microsatellite observation mission for NEOs appears feasible in the near-term.
Paramedics described it as a "truly difficult mass casualty incident", one that drew a huge response from police, fire and paramedics.

Whereas the relevance of minimally invasive surgery is rapidly rising, OPN remains the most frequently applied approach, which is especially valuable for difficult renal masses [ 6– 8].
They have been built in laboratories, but will be difficult to mass produce.
The species is difficult to mass propagate by seed due to the low percentage of germination and limited dormancy period.
That is not yet the case in Europe, where privacy laws make it difficult for mass mailers to identify household income levels by postal zone.
Although the performance of the selective emitter solar cell is fairly good, its fabrication process is very complicated, making it difficult for mass production [9].
Nanometer-scale wires are stronger and more capable of conducting heat than the average wire, but manufacturing them or their cousins, nanotubes, is difficult and mass production is currently impossible.
Globally, mainly H. bacteriophora, H. marelatus, S. glaseri and S. scarabaei are known to be virulent to white grubs (Klein and Georgis, 1992; Selvan et al., 1993; Ansari et al., 2003; Koppenhöfer and Fuzy, 2003 and 2009; Grewal et al., 2005; Bal et al., 2014; Guo et al., 2015), but some, such as S. scarabaei, are difficult to mass-rear (Koppenhöfer and Fuzy, 2003 and 2009).
