sep demo
SEP Demo

Description:

  • Perform high power SEP demonstration
  • 30kW solar power
  • Battery augmentation to facilitate 200kW short duration
  • Total system delta-v: ~15km/sec
  • System will demonstrate two high power EP engine technologies: VASIMR & Hall_or_ION
  • Demo will also make use of mini free flying inspection spacecraft
  • Utilize emerging advanced solar technologies such as DARPA’s FAST or SOLAROSA.

Approach

Schedule/Cost:

  • Vehicle can launch to LEO on Falcon 9
  • Vehicle can achieve Mars orbit
  • Delta-v split between two EP technologies
  • Design, Development, Test, & Evaluation ~4 years
  • Launch Vehicle Categories: Falcon 9, Atlas V, Delta IV – final variant depends on final SEP tug mass and cargo
  • Cost estimate: ~$500 million (includes launch cost on F9)

Justification:

  • All future exploration plans beyond LEO will make use of SEP technology elements in the architectures.
  • SEP is a requirement for manned exploration beyond CIS-Lunar space.
  • SEP is orders of magnitude more efficient than chemical and will result in smaller vehicle architectures, and allow selection of smaller (and cheaper) launch vehicles
