The Apollo spacecraf_ command and service modules will be
modified to enchance their potential use in an emergency mode.
The decision followed an extensive study of consumables and
emergency equipment aboard the spacecraft as recommended by the
Apollo 13 Review Board.
The modification includes adding a 400 amp hour battery in the
service module as an alternate power source in the event the spacecraft's
main power supply failed. Provisions will be made to store
an additional 20 pounds of potable water in the command module'
Earlier, a decision was made to add a third oxygen tank in
the service module as a part of the redesigned spacecraft oxygen
system.
These modifications would permit a powered down mode of
emergency flight from lunar orbit to landing back on earth.
