NASA’s daring Parker Solar Probe broke its own speed record during a recent extremely close flyby of the Sun, aided by gravity assists from Venus.

On September 27th, Parker reached about 395,000 mph, beating its previous high of ~365,000 mph from November 2021. It also set a new solar proximity record.

Harnessing Venus Gravity to Accelerate Toward Sun

Parker leverages Venus flybys to shed orbital energy and get closer to the Sun’s surface on its unique elliptical trajectory.

This allows the probe to accelerate to tremendous velocities while zooming near the Sun’s blistering heat and intense gravity.

Previous Record Shattered by Latest Solar Approach

Parker’s November 2021 record at around 365,000 mph seemed unattainable. But its latest pass smashed that by cresting nearly 400,000 mph.

The September 2022 flyby demonstrates the value of the Venus gravity assists in enabling extreme speeds.

Bringing Spacecraft Closer to Sun Than Ever Before

At its point of closest solar approach, Parker reached just 4.5 million miles from the Sun’s surface.

This shatters the prior record for nearest solar pass by a human spacecraft.

Parker’s 2024 Solar Approach Could Bring Even Faster Speeds

Parker has one more Venus flyby planned, setting up its 2024 closest encounter that’s predicted to be under 4 million miles from the Sun.

Final Epic Solar Pass in 2024

Parker’s grand finale will occur in 2024 when it skims just 3.83 million miles from the Sun’s surface after the last Venus slingshot.
