Task Goal

Approach the visible satellite conservatively from the front, keep it observable, and stop only when fresh visual evidence suggests a safe near-front stand-off at about 1 meter from the target surface.

Front-Approach Strategy

1. If the target is not visible, do not drive forward blindly.
2. If the target is visible but not centered, use set_attitude() to recenter first.
3. When the target is centered enough, advance with small dx steps.
4. Reduce the forward step size as the target becomes larger in the image.
5. If the target becomes cropped, suddenly very large, or visually unsafe, retreat slightly instead of advancing.

Completion Guard

• Only stop after two consecutive fresh frames show a stable, visible, front-facing near view.
• If the target is lost during the approach, switch to a conservative recovery policy instead of continuing forward.
