T3-01 Spin-Up to Artificial Gravity

TIER 3 EXPERT NOT STARTED

Spin up spacecraft end-over-end around transverse axis (Pitch or Yaw) to generate Mars-equivalent surface gravity.

Pass Criteria & Flight Boundaries

  • Spin up spacecraft around transverse Y axis to +31.86 deg/s (+/- 0.20 deg/s) with transverse rates below 0.05 deg/s
  • Flight envelope limit: Max 45s
  • Monopropellant reserve: Maintain at least 50.0 kg
  • Transverse rate limit: Max 5.00 deg/s

Mission Instructions

1. Centrifugal Artificial Gravity & Gyroscopic Coupling

Spinning the spacecraft habitat around its longitudinal roll axis generates centrifugal artificial gravity (a = ω²r). Because the spacecraft has an asymmetric inertia tensor, spinning at high roll rates introduces Euler cross-coupling torques: any residual pitch or yaw rate will precess into nutation wobble.

2. Spin-Up & Nutation Damping

To establish a stable artificial-gravity spin envelope:

  • Null Transverse Wobble First: Zero out pitch and yaw angular velocities before accelerating the roll axis.
  • Spin Up Roll Axis: Use roll control authority to accelerate longitudinal roll rate into the 18.0 to 22.0 deg/s target band (~0.35 G rim acceleration).
  • Active Nutation Suppression: Continuously damp transverse pitch and yaw rates below 0.25 deg/s and hold the spin envelope steady for 5.0 seconds.

3. Prompt Your Autonomous Agent

Prompt Antigravity to synthesize a spin-stabilization controller for mission T3-01:

Adapt our flight computer to complete mission T3-01 (Centrifugal Artificial Gravity):
1. Suppress transverse pitch and yaw rates below 0.25 deg/s.
2. Spin the roll axis into the 18.0 to 22.0 deg/s target window and maintain active nutation damping for 5.0 seconds.
