points to Ars Technica's Wednesday report that NASA has announced a 2018 launch date
for its InSight mission to Mars, two years after its original launch date; the date slip gives engineers time to fix problems with the spacecraft's seismometer system
. Adds wbr1: "Even with the failure and extra cost, I think this is the type of mission we should be doing more of. We need more landers and rovers, everywhere we can put them. The science benefit is high, but the cost is magnitudes lower than launching meatbags and all the attendant support they need."
