The reviewers decided that the canle was the the instruments number one concern jpl realized that they would be responsible for guaranteeing the performance of the cable (cid:1006). Such an act could mean the death of future collaborations. It was descoped because of the instruments cost they were only 1. 5 million$ over the original set pricing (cid:1007).

It produces a small amount of heat which is converted to electricity: for the new rovers the capsule and chautes were the biggest ones yet, mars atmosphere is only 1% as thick as earths.
