There's no "risk" involved here; if you design the satellite so that it doesn't go through an eclipse, then the highest-likelihood scenario it somehow does anyway involves us miraculously inventing planet-moving engines in twenty years. Meanwhile, the other side involves a heavier payload, more moving parts, and more stuff in orbit. | |
