A NASA spacecraft will make its second close brush with the sun. The Parker Solar Probe made its record-breaking first pass within 3.8 million miles of the scorching sun in December, flying closer than any object sent before. Parker will attempt the journey again on Saturday. Scientists hope the data from Parker will help them better understand the sun’s outer atmosphere and what drives the solar wind. Parker was launched in 2018 to get a close-up look at the sun and is the fastest spacecraft built by humans. A NASA spacecraft will make its second close brush with the sun.
