Quote from the article
"The exact time of the closest approach to the sun, or perihelion, will be around 8:16 a.m. EST (1316 GMT), when the spacecraft will be traveling at an incredible speed of around 364,639 mph (586,829 kph).
Amazingly, this speed, 200 times faster than a bullet fired by a rifle, isn't the record velocity for the craft. On Nov. 21, 2021, the
Parker Solar Probe achieved a slightly higher speed of 364,621 mph (586,000 kph) during its 10th solar flyby, becoming the fastest spacecraft ever built, although it will break that record later in its mission."
So how is the quoted speed of 364,621 mph on Nov 21 2021 higher than todays quoted speed of 364,639 mph ?
