Earlier on this blog we noted a Business Insider story that claimed that an iron cap placed atop an underground nuclear test in 1957 shot upwards at a speed of 125,000 miles per hour, allegedly becoming the “fastest manmade object ever.” Whether or not this actually happened, the record has been decisively broken by NASA’s Parker Solar Probe, which “was clocked at over 330,000 miles per hour as it zipped through the sun’s outer atmosphere.”
