Amongst its many onboard gadgets, the car-sized robotic has a machine on its stomach known 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 kind the grime 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. They programmed it to vibrate out just a little tune. There, on their own on a planet 236.6 million miles from house, Curiosity sang happy birthday to itself.
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. On a much less tragic word, robotic lawnmower firm Husqvarna had a fleet of its machines use their alarm methods to sing comfortable birthday to Curiosity in 2022, celebrating the rover’s large ten.
