430,000 mph is fast for a Satellite ๐ฐ
Thatโs 690,000 km/h (430,000 mph) โ or 0.064% the speed of light! ๐๐ป
Launched by NASA in 2018, the Parker Solar Probe is designed to study the Sun up close, venturing closer to our star than any spacecraft in history.
The probe reaches its record-breaking speeds thanks to the Sunโs immense gravitational pull. As Parker approaches its closest point to the Sun โ called perihelion โ it accelerates dramatically. Its orbit is carefully designed to take advantage of gravity assists from Venus, which increase its velocity with each pass.
Eventually, Parker will come within just 6.2 million kilometers (3.9 million miles) of the Sunโs surface โ closer than any previous mission. At that distance, the spacecraft endures extreme conditions, with temperatures soaring to 1,377ยฐC (2,500ยฐF).
To survive this environment, the probe is equipped with an advanced carbon-composite heat shield, which protects its instruments from the intense heat and radiation.
This daring mission is helping us unlock the mysteries of the solar corona, solar wind, and space weather โ phenomena that affect everything from satellite communications to astronaut safety.
