Volcanoes Would Be Good Future Targets - Universe Today
When selecting targets for Spirit and Opportunity, NASA engineers were very cautious about where the rovers could land. They needed to choose targets which had a low elevation, flat terrain, and free of large boulders that could destroy the spacecraft. Fortunately, both Gusev Crater and Meridiani Planum have enough scientific value to make the trip worthwhile. Since the airbag technology has been so successful, future missions might get a little more dangerous, like landing on a volcano.
