Ares V Payload Development and Accommodation

1
Ares VPayload Development and Accommodation

• Nuclear Accommodation and Certification
• Design must not prevent the use of radioactive
  power source
• Start early in certification (7 years) NEPA
  Compliance
• On pad cooling (heat rejection) and late
  integration
• Future reactors
• Provide multi-spacecraft payload capability
• Standard Altair adapter
• Generic interface definition
• ESPA-like
• Shroud load-sharing
• Provide late payload access
• Centaur fueling - other upper stage
  configurations
• Late maintenance - pre-launch failures dont
  preclude shroud interior mobility
• Nuclear powered payloads

Ares VPayload Development and Accommodation

• Provide cleanliness, purges,
• Planetary protection - current launcher
  considerations
• N2 purges
• Storable propellant handling like NTO, Hydrazine
  for long missions
• Hazardous material monitoring, handling
• Venting
• Keep launch loads at todays levels for current
  launch vehicles - not worse than Delta IV (check)
  - acoustics, vibration, thermal
• High C3 burns - 500 second limit may impact deep
  space missions
• What are the limits of the qual program
• Options for high C3 planetary missions
• Payload Accommodation
• Umbilicals for active payloads
• Data
• Power

Ares VPayload Development and Accommodation

• Volume potential issue
• Centaur upper stage fits in shroud (4 m left)
• Aeroshell for planetary landers
• Ares V is enabling - Cheap dumb mass examples
  (c.g. considerations)
• Propellant, Copper, Solar Arrays, Shielding
• Use shroud as heat shield for human missions
  (existing DRM)
• Launch Dates
• 2026-2028 - gravity assist for interstellar
  mission (2015 even better)
• Titian orbiter ?
• Neptune Triton orbiter?
• Humans to NEOs - ISRU needs
• Others?
• ESMD and SMD should continue and enhance
  communication
