... For example, LISA will observe hundreds of stellar mass binary black hole systems, some of which would cross into the band of ground-based observatories like LIGO/Virgo weeks to months later. LISA also complements nano-Hz gravitational wave measurements using pulsar timing arrays; the latter are sensitive to billion solar mass black hole mergers, whereas LISA is sensitive to ~104–6 solar mass black hole mergers (see Figure 2.14)

... Deviations from the optimal budget profiles that reduce funding in years of peak spending will extend development periods and increase the total mission cost relative to this analysis. This survey emphasizes the need for investment in maturation programs (e.g., the Great Observatories Mission and Technology Maturation Program for NASA, and ngVLA design and prototyping efforts for NSF)
