The application receives regular updates with modules featuring timely events such as the end of the "Cassini" mission, and arrival of spacecraft such as MAVEN to Mars and the Solar eclipse of August 21, 2017. The application received heavy use during the entry, descent and landing of the Mars Science Laboratory. The landing of MSL brought an additional 739,000 visits and 20 terabytes of data was streamed from JPL servers that weekend in support of the software. Touchdown time of the rover in the software was predicted by team planning spacecraft trajectory weeks ahead but was accurate within a fraction of a second.
