The NASA spacecraft Parker Solar Probe was launched in August to explore the Sun’s atmosphere (corona). Today, it surpassed 153,454 miles per hour - as calculated by the mission team - making it the fastest-ever human-made object relative to the Sun. This breaks the record set by the German-American Helios 2 mission in April 1976. Parker Solar Probe will repeatedly break its own records, achieving a top speed of about 430,000 miles per hour in 2024.
