<h2>Communications</h2>
<p class="ml-4">
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.
</p>
<p class="ml-4">
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.

<h2>Tools</h2>
<p class="ml-4 mb-1">
Sojourner was designed to study the surface of Mars by collecting and analyzing rock
samples, taking pictures and more using the following tools:
</p>
<ul>
<li>
An <abbr title="Alpha Proton X-ray Spectrometer"><em>APXS</em></abbr> for determining
elemental composition of soil, rocks and other materials on the surface of Mars.
</li>
<li>
<em>Rover Control Software</em> for coordinating movement, studying terrain features,
and viewing
the nearby area in 3D space.
</li>
<li>
<em>Three cameras</em>, one color, two monochrome. However, the operators used images
from the
lander's
IMP camera system primarily, as it had higher quality on top of having a height
advantage over the rover.

<h2>Autonomy</h2>
<p class="ml-3 ml-xl-4">
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.
</p>
<p class="ml-3 ml-xl-4">
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.
