What you know
Book 3: Death's End
- Ch 46A Crisis Era engineering project that failed its objectives and left nothing of technological value; it was forgotten even before the Great Ravine.
- Ch 46A cable holding the probe's sail broke near Jupiter's orbit, so the probe deviated and Earth lost track of it.
- Ch 46Nearly three centuries later, the project brought hope to an Earth mired in despair, because its probe carried Yun Tianming's brain.
Key moments
- Book 3 · Ch 46Trisolarans capture Yun Tianming's probe
A ship of the First Trisolaran Fleet, probably the one that never decelerated, intercepted the Staircase probe carrying Yun Tianming's brain, likely 30 to 50 years earlier, aided by sophon-gathered flight parameters and luck.
