Flight-team engineers for NASA's Mars Exploration Rover Mission were encouraged on the morning of January 22nd when Spirit sent a simple radio signal acknowledging that the rover had received a transmission from Earth.
However, the team is still trying to diagnose the cause of earlier communications difficulties that have prevented any data being returned from Spirit since early Wednesday.

A traveling robotic geologist from NASA has landed on Mars and returned stunning images of the area around its landing site in Gusev Crater. Mars Exploration Rover Spirit successfully sent a radio signal after the spacecraft had bounced and rolled for several minutes following its initial impact at 11:35 p.m. EST (8:35 p.m. Pacific Standard Time) on January 3.
