CBS News - NASA probe sets record as closest object to the sun
The Parker Solar Probe, launched in 2018, has become the closest manmade object to the Sun, traveling at unprecedented speeds of 430,000 mph. It is currently within the Sun's atmosphere, known as the corona, at a distance of 3.8 million miles from the Sun. This mission aims to explore solar mysteries, such as why the Sun's surface is cooler than its atmosphere. The probe uses the Sun's gravitational force to achieve its high speed, allowing it to travel from New York City to Tokyo in less than a minute. Despite the challenges of communication delays due to its speed and protective heat shield, NASA expects to start receiving data from the probe on New Year's Day. The mission has already provided valuable insights and is expected to keep scientists busy for years with its findings.
