The Parker Solar Probe spacecraft, NASA’s newest and most ambitious effort to study the sun, has broken a lot of records: it has gotten closer to the sun than any other spacecraft to date, its instruments have operated at the hottest temperatures, and the probe is the fastest human-made object ever. But those records come at a cost: The spacecraft is moving so fast that running into even a tiny grain of dust can lead to serious damage.
