ISS Research Accommodations Status 4 December 2002 (Data through 30 November 2002)
Definition of Terms and Status Levels
U.S Research Investigations Accommodated
U.S. Investigator: The principal person selected or
approved by NASA to conduct a research
investigation on-board ISS.
No. Of Investigations (Cumulative) and Total Number
of Investigations to Date: The cumulative number of
U.S.-sponsored investigations carried out on ISS to
date. This number also includes any international
investigations conducted within U.S.-provided
accommodations as part of agreements with the ISS
international partners. If an investigation requires
experimentation on more than one increment, it is
counted only once. The cumulative number is plotted
at the date of each Shuttle flight to ISS, which is when
new investigations are added.
Source: The Investigator Master List, maintained by
the Lead Increment Scientist, provides the number per
increment. The Increment Scientist also provides the
cumulative number per Shuttle flight.
Increment Length: The time period that an expedition
crew is on orbit. It is measured from their launch date
to their ISS undock date, and is documented in the
Increment Definition Requirements Document (IDRD)
Flight Program Definition matrix.
Research Objectives Accommodated through
Increment X: The percent of research objectives
accommodated for each investigation is calculated,
then the values are averaged together to determine
percent of research objectives accommodated through
Increment X.
Source: Accommodated Research Master List,
maintained by the Lead Increment Scientist.
Total Investigation Duration to Date: The time that an
investigation takes advantage of the effects of the
space environment (microgravity, radiation, vacuum,
vantage point, etc.) in the conduct of the research. The
time starts with investigation setup and ends with
investigation take-down or deactivation. The times
calculated for each investigation are added together to
produce this Total Investigation Duration to Date.
Source: The Increment Scientist assisted by
investigation payload planners at NASA/Marshall
Space Flight Center using Final Payload On-Orbit
Operations Summaries, Payload Operation Integration
Function (POIF) Crew Training Overviews, and
Payload Tactical Plans.

Human Research Investigation Duration to Date: The
time that a human life sciences investigation takes
advantage of human subjects being exposed to the
space environment. The times calculated for each
investigation are added together to produce this total
Human Research Investigation Duration.
Source: The Increment Scientist assisted by investigation
payload planners at NASA/Marshall Space Flight Center
using Final Payload On-Orbit Operations Summaries,
POIF Crew Training Overviews.
Crew-Tended Research Time: The cumulative hours of
that the ISS crew performs U.S.-sponsored research
investigations, including time both within and outside of
the normal workday.
Source: ‘Actual’ crew time is documented in the
Summary Crew Tracking Matrix, provided by the Payload
Operations Integration Center (POIC).
Research Objectives Accommodated Per Increment:
Each investigation may have several objectives,
experiments, or steps to be carried out during an
increment. The percent actually accommodated by the
ISS is calculated for each investigation, then all
investigations during the increment are averaged
together to determine the per increment value. Only the
performance of ISS to accommodate the investigation
is measured, independent of the performance of the
experiment hardware.
Source: Accommodated Research Master List,
maintained by the lead increment scientist.
Number of Investigations Planned Per Increment: The
number of U.S.-sponsored investigations planned 12
months in advance for an increment, including both
new and continuing investigations occurring during that
increment.
Source: Same as above.
Number of Investigations Executed Per Increment: The
number of U.S.-sponsored investigations actually
carried out during an increment, including both new
and continuing investigations.
Source: Same as above.
