 Mr. Green - When the DPS is used for backup propulsion, do we jettison the SPS propellants?

ANSWER - There is no capability to jettison SPS propellants.

Dr. Mueller - Have the procedures, etc., have been worked out for all of the abort possibilities?

ANSWER - No.

Dr. Von Braun - Why the difference in the translunar and transearth transit times?

ANSWER - The trans lunar phase uses a free return trajectory which limits the transfer time to a narrow band. The transearth time is primarily limited by the energy available and the amount of consumables remaining.
