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
Timeline of Mars Science Laboratory to the drill mechanism and the rover started moving again on December 9. The robotic arm is functional, and the "Curiosity" team performed diagnostics on the drill mechanism throughout 2017. On June 4, 2018, NASA announced that "Curiosity" ability to drill has been sufficiently restored by changing the drilling methods. Since September 15, 2018, a glitch in "Curiosity"'s active computer (Side-B) has prevented "Curiosity" from storing science and key engineering data. On October 3, 2018, the JPL began operating "Curiosity" on its backup computer (Side-A). "Curiosity" will store science and engineering data normally using its Side-A computer until the cause
