Amongst its many onboard units, the car-sized robotic has a machine on its stomach referred to as the “sample-analysis unit.” Curiosity makes use of its mechanical arm to place soil within the sample-analysis unit, which then vibrates at totally different frequencies to type the filth into totally different little cups. Then the cups warmth as much as launch gasses, that are studied in numerous methods.
2013 marked the primary anniversary of Curiosity’s arrival on Mars, and the scientists at NASA considered one other means to make use of the sample-analysis unit.

Curiosity has had ten birthdays since then, however the energy used up for singing is a restricted useful resource. NASA solely let Curiosity sing to itself that one time.
