Propulsion

• 265GW Nuclear Thermal Rocket propulsion system
• 3 distinct phases
• Acceleration phase in the solar system
• Trajectory Control and correction between the two systems
• Deceleration phase in the Epsilon Eridani system
• The two-stage spacecraft propels the spacecraft up to 6,500km/s as it leaves the solar system
• 1,250 t of liquid hydrogen are consumed
• The voyage time is about 485 years 3 months

Electronic Resiliency

A variety of techniques will be used to protect the electronic components of the spacecraft. They include:

• Space Hardening - Silicon on Insulator fabrication processes
• Physical shielding - Electronics enclosure will be made of high quality polytherene
• Logical correction - A variety of bit error correction schemes will detect and correct faults
• Redundant elements

Power

4 RTG per Relay:

• Provided Power 500W
• Time Life 1000 years

Budget
