ISS Safe Haven

Some time ago, there was a discussion on ISS as a safe haven.

From the Return to Flight task group report ( http://www.returtoflight.org ),
there are 3 items related to this, all deemed "closed". So it would seem that
the study has already been done.

Ops-016
ISS Consumable, Sparing
and Configuration for 2-
Member Crew
Provide current and projected consumables
(water, propellant, CO2 removal capability, food
and other crew provisioning) for current 2-member
crew with projected needs on Russian assets
(e.g. Soyuz rotations, crew rotations, Progress
missions, etc.) for extended on-orbit maintenance
of ISS without Shuttle availability. Also provide
data on critical ORU sparing to maintain minimum
acceptable habitability and mechanisms for
providing that sparing without Shuttle.
Closed


Ops-017
Contingency Shuttle Crew
Support Data and
Supporting Analysis
Provide minimum ISS system requirements,
consumables, etc. to maintain crew of 6-10 for
contingency support of the Shuttle crew. Provide
plans for use of Soyuz to bring down partial crew
and length of time remaining crew can survive on
ISS. Provide plans and timeframes for sending
additional Soyuz and/or Shuttle rescue missions
to retrieve remaining crew members. Provide
forward work to verify feasibility of this concept
and reliance on Russian segment and assets.
Closed




Ops-018
ISS Safe Haven and ISS
Extended Duration Orbiter
Study Results
Provide study results from ISS Program led
analysis of the ISS as a safe haven to provide
larger on-orbit crew size with limited Soyuz return
capability. Also provide study results from ISS
Program led analysis of use of EDO Shuttle
missions to provide a larger crew for utilization.
Both study results should discuss ISS minimum
system capability, consumables projections,
number of crew supported as a function of time,
and reliance on Russian segment and other
assets
