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
Curiosity (rover) ("Mount Sharp"), at the center of the wide crater. Thus, it is believed that the rover may have the opportunity to study two billion years of Martian history in the sediments exposed in the mountain. Additionally, its landing site is near an alluvial fan, which is hypothesized to be the result of a flow of ground water, either before the deposition of the eroded sediments or else in relatively recent geologic history. According to NASA, an estimated 20,000 to 40,000 heat-resistant bacterial spores were on "Curiosity" at launch, and as much as 1,000 times that number may not have been
