NASA solar probe becomes fastest object ever built as it 'touches the sun'

The Parker Solar Probe was clocked at over 330,000 miles per hour as it zipped through the sun's outer atmosphere.

Record breaker.


Nothing built by human hands has ever traveled faster than NASA's Parker Solar Probe, a diminutive, scorch-proof spacecraft about the size of a small car that is practically "touching the sun." In late April, it smashed two wild space records, dethroning the previous champion -- which also happened to be NASA's Parker Solar Probe -- and its journey is really just beginning.

The probe, which launched in August 2018 on a mission to study the sun, has been flying ever closer to our solar system's furnace, using the planet Venus as a slingshot. On April 29, during its closest approach to the sun (known as "perihelion"), Parker was traveling at an almost unfathomable speed -- fast enough to circle the Earth 13 times in a single hour.

Parker set two records back in February 2020:

  • Fastest human-made object: 244,255 mph (393,044 km/h).
  • Closest spacecraft to the sun: 11.6 million miles (18.6 million kilometers).

But those records have now been surpassed. The latest:  

  • Fastest human-made object: 330,000 mph (532,000 km/h).
  • Closest spacecraft to the sun: 6.5 million miles (10.4 million kilometers).

Those are some strong records to hold, and this isn't the end, either. Parker should break its own record later in the year when it uses another Venus flyby to slingshot closer to the sun. Perihelion is expected to occur on Nov. 21.

The spacecraft is already revealing some of the sun's great mysteries. In December 2019, Parker's first batch of data was released in the journal Nature, pulling back the (incredibly bright) curtain on the charged particles and plasma dynamics in the sun's outer atmosphere.
