The Mars Pathfinder and its Sojourner rover are back in top form after some adjustments, National Aeronautics and Space Administration officials said.
"This is what we expect, for things to be nice and calm," mission manager Richard Cook said Wednesday after the spacecraft sent two streams of pictures and science data.
Lander and rover were operating "flawlessly" with newly updated software, while tinkering with an antenna in Spain overcame communications glitches, flight director David Gruel reported.
Today, Sojourner was to dig a little dirt pile that can help scientists understand how dense the soil is on Mars. Operations were cut back for more than a week because the computer on the Pathfinder lander was resetting itself as the weather tasks were overloading it.
