With some surface mobility, the probe is able to sample the soil and water, as well as the air. The Ship watches from its orbit, monitors the reports, analyses. After a search lasting millenia, there is no cause for hurry. Storm activity appears normal, not a threat. The time has come.
Caution is essential.
Once the landing has begun, there can be no fallback plan, no recovery from any error. Systems which have never been used are activated, tested. The Ship is ready. Finally, like a butterfly returning to the earth, the Ship sheds its beautiful wings, and hurling fire at the planet nudges itself tentatively, cautiously, into the atmosphere, drops on a pillar of fire beyond return. The Ship does not know fear.
