What kind of wind will Spirit have to endure?
On the surface, Spirit will be just find. It is designed for a 90 day mission. During landing, we found low winds of around 20 kts which were not expected. These were countered by our small attitude control rockets, which were designed for this purpose, and increase the probability of a successful landing. From the Viking era, the largest dust storms measured were about 30 miles/hour.
