Description: Unlike Earth, the Mars has strangely tow speeds of sound. On Mars low-pitched and high-pitched sounds don't travel at the same speed in the same medium. This video explains why Mars has two different sound speeds? Human has first time heard the sounds on the red planet by the NASA's Perseverance rover. It is the first Mars mission equipped with microphones. Researchers have analyzed sounds recorded by the microphones mounted on the perseverance rover. For the study, sounds from the rock-zapping laser of the rover and ingenuity helicopter flight were analyzed. The sounds speed recorded by the perseverance rover has confirmed that the speed of sound is slower on Mars, but the strange thing that the rover reveal is that all sounds don’t propagate at the same speed on Mars. The high-pitched sounds travel significantly faster than low-pitched sounds. The strange behavior of carbon dioxide molecules is the reason for significant variation in sound speeds on Mars. The thin Martian atmosphere is mainly composed of carbon dioxide. The Carbon dioxide molecules act strangely in cold and low pressure. ------------------------------------------------------------------- NHN New Horizon Youtube► youtube.com/c/NewHorizon2 Facebook► facebook.com/newhorizon111 Twitter► twitter.com/NHN_Newhorizon Instagram► instagram.com/newhorizonnhn ------------------------------------------------------ #mars #nasa #perseverancerover
