Parker Solar Probe prepares for liftoff Today’s Video of the Day from NASA Science News describes the mission of the Parker Solar Probe, which will approach the Sun closer than any other spacecraft in history.
Over the next seven years, the Parker Solar Probe will make its way within 3.9 million miles of the Sun’s surface. This is seven times closer than the current record-holder, the Helios-B Spacecraft.
According to NASA, a primary goal of the mission is to learn more about solar wind, which is one of the least understood events in the solar system. The probe will also investigate why the Sun’s atmosphere is so much hotter than the Sun itself. Parker Solar Probe prepares for liftoff shown in video above shows the mission.
The journey will officially begin at 3:33 a.m. EDT on Aug. 11th from the Cape Canaveral Air Force Station in Florida. Mission Overview. NASA’s Parker Solar Probe will be the first-ever mission to “touch” the Sun. The spacecraft, about the size of a small car, will travel directly into the Sun’s atmosphere about 4 million miles from the surface. Parker Solar Probe launched aboard a Delta IV-Heavy rocket from Cape Canaveral, Aug. 12, 2018 at 3:31 a.m. Eastern time. Parker Solar Probe’s second perihelion will occur on April 4, 2019. During the seven-year mission, the spacecraft will perform a total of 24 perihelia, with the last three bringing the spacecraft to less than 4 million miles from the Sun’s surface.
