Method to maintain artificial gravity during transfer maneuvers for tethered spacecraft

摘要: Abstract Artificial gravity has long been proposed to limit the harmful effects of micro-gravity environment on human crews during mission Mars. A tethered spacecraft spinning at 4 rpm (to avoid motion sickness) provides an attractive configuration. However, if is required spin down for impulsive maneuvers and then up interplanetary travel, propellant cost may be unacceptably high. This paper proposes a maneuver that performed while thus avoiding additional spin-down spin-up maneuvers. control law provided achieve Δ V maintaining rate. hypothetical from Earth Mars analyzed using new which, in this example, save over 700 kg propellant.
