- Sojourner +
+ Sojourner is unique among the 4 rovers to successfully deploy on Mars in that it required + it's lander to stay in communication with Earth. The rover was not equipped with a high gain + antenna, which is required in order to communicate with Earth over large distances. +
++ This limitation forced the rover to stay within a certain range of the lander, and + throughout it's lifetime on Mars, it never traveled more than a few dozen feet from the + lander. +
++ Sojourner was designed to study the surface of Mars by collecting and analyzing rock + samples, taking pictures and more using the following tools: +
++ Sojourner was an important step in Robotics due to the nature of the mission. + With such a long distance between Mars and Earth, radio communications took around 14 + minutes to receive, and then another 14 minutes to send back. +
++ As such, human telegraphed movements too slow for the mission, and while complete autopilot + is impossible for such a complex mission, the rovers, landers, and spacecraft made by NASA + had to be programmer with autopilot. +
++ To solve this problem, Sojourner, along with every rover to land on Mars, is equipped with + software dedicated to autonomously moving the rover across the martian surface. +
++ While Sojourner was comparatively basic in it's software's autonomy, the software was + helpful to operators in visualizing and telegraphing instructions across the rocky terrain + of Ares Vallis. +
