NASA has not sent any missions or spacecraft to spend time on the surface of the Sun

NASA has not sent any missions or spacecraft to spend time on the surface of the Sun, as it is an inhospitable and extremely hostile environment. However, NASA has conducted various solar observations and research missions using spacecraft like the Solar Dynamics Observatory (SDO) and the Parker Solar Probe to study the Sun from a safe distance. You can find videos and information about these missions and their observations on NASA's official website or their YouTube channel.
