NASA launches Parker solar probe on mission to 'touch the sun'

The video explains the sideways motion of objects relative to the sun at 7000 mph and the need to cancel this motion to travel towards the sun. It details NASA's Parker Solar Probe mission, which involves reducing its speed by 50,3000 mph and using Venus flybys to adjust its orbit closer to the sun. The probe aims to fly through the solar corona to study and predict solar wind behavior.
