The ISS as a Science Observing Platform The ISS is an excellent platform for many observations once
you match the observation to the capabilities of the Station.
It is a very useful platform with some highly desirable features Mass, data rate, and power are generally not design limitations The availability to replace and re The precessing orbit enables some measurements, in particular
allowing cross calibration with LEO polar satellites for Earth Observation
The relatively low altitude improves many imaging applications
It is niche platform, not suited for all observation objectives The platform is more jittery, has more contamination, and has
numerous operating restrictions due to frequent visits and human presence
For Earth Observations, the low inclination orbit does not cover the globe, and the precessing orbit is not ideal for measurements which need a consistent local time for observations
The observing opportunities for Heliophysics and Astrophysics are well understood but often restricted by orbit dynamics and viewing obstructions

Venture-Class is a Tier-I Decadal Survey recommendation Science-driven, PI-led, competitively selected, cost- and schedule-
constrained, regularly solicited, for orbital and suborbital missions Venture-class investigations are open to all science questions. They may
complement the systematic missions identified in the Decadal Survey, or may directly address science objectives from those missions
The selected missions/instruments provide flexibility to accommodate scientific advances and new implementation approaches
EV Instruments in particular may be good fits for the ISS platform Ample resources (power, data rate, cooling, mass) Well defined interfaces and infrastructure
EVS Sustained Sub-
Orbital Investigations
EVM Complete, self-contained, small missions
EVI Full function, facility-
class instruments Missions of Opportunity
