Late Monday, it passed the speed mark of 153,454 mph (247,000 km/h). NASA declared it "the fastest-ever human-made object relative to the Sun." Again, it broke a record set by Helios 2. > The spacecraft isn't anywhere close to done setting records. By 2024, it should be up to a mind-boggling 430,000 mph (692,000 km/h). It will also get much, much closer to the sun thanks to a high-tech heat shield designed to protect it from our star's intense temperatures.
