The orbiter, called the Trace Gas Orbiter, will look for trace gases in the Martian atmosphere. In its search for compounds made of carbon and hydrogen, and chemicals containing sulfur, the orbiter will be able to map the hydrogen on Mars up to a meter below the surface. The mission will create a map of Mar's water ice with ten times the resolution we have now. ExoMars 2016 will also include a small test lander known as Schiaparelli. The small lander will be testing the ESA's Mars landing technique, which will help when the ExoMars 2018 mission arrives with a more advanced lander and rover. The mission was originally scheduled to launch in January, but back in October the ESA discovered some issues with Schiaparelli's sensors used to monitor fuel pressure. Instead of risk the sensors leaking fuel and ruining the mission, they delayed the launch and removed the sensors altogether. The launch window of the mission stretches from March 14th through March 25th. And the launch will be livestreamed from the ESA's website.
