Curiosity (rover) no chance of obtaining funds in Europe, at that time, of the scale previously considered necessary for a Mars rover, so the team used innovative methods to reduce the cost to less than 4% of the cost of the "Curiosity" mission. They also had only one shot, with no funding for repeat missions (it was named "Beagle 2" as a successor to , not to an earlier rover). It was considered a large risk, and, although "Beagle 2" did successfully survive its entry, descent, and landing, incomplete deployment of the solar panels hampered communication back to Earth. The team has
Spirit (rover) soil. This was not the first of the mission's "embedding events" and for the following eight months NASA carefully analyzed the situation, running Earth-based theoretical and practical simulations, and finally programming the rover to make extrication drives in an attempt to free itself. These efforts continued until January 26, 2010 when NASA officials announced that the rover was likely irrecoverably obstructed by its location in soft soil, though it continued to perform scientific research from its current location. The rover continued in a stationary science platform role until communication with "Spirit" stopped on March 22, 2010 (sol ). JPL continued
