That’s 690,000 km/h (430,000 mph) — or about 0.064% the speed of light!
NASA’s Parker Solar Probe, launched in 2018, is on a daring mission to study the Sun like never before. It’s the closest any spacecraft has ever gone to our star. Parker reaches its incredible speed thanks to the Sun’s powerful gravity. As it swings by the Sun at its closest point (called perihelion), it picks up massive speed — boosted even more by several gravity assists from Venus. Eventually, the probe will get within just 6.2 million km (3.9 million miles) of the Sun’s surface. That’s insanely close — and hot!
Temperatures around the spacecraft can reach 1,377°C (2,500°F). To survive this fiery environment, Parker is equipped with a cutting-edge carbon-composite heat shield, keeping its instruments safe while it sends back groundbreaking data about solar winds, magnetic fields, and the mysterious outer layer of the Sun — the corona.
