WISPR Team Images Turbulence within Solar Transients for the First Time

Visible light observations of a Coronal Mass Ejection (CME) acquired by the Wide Field Imager for Solar Probe (WISPR) telescopes

NASA’s Parker Solar Probe has been in studying the Sun for the last six years. In 2021 it was hit directly by a coronal mass ejection when it was a mere 10 million kilometres from the solar surface. Luckily it was gathering data and images enabling scientists to piece together an amazing video. The interactions between the solar wind and the coronal mass ejection were measured giving an unprecedented view of the solar corona.

Parker Solar Probe Was Blasted by Coronal Mass Ejections 28 Times in 4 Years

NASA’s Parker Solar Probe (PSP) was launched on August 12, 2018, with the goal of becoming the first spacecraft to touch the Sun while teaching us more about our host star than any spacecraft or solar instrument in human history. Now, a recent study submitted to The Astrophysical Journal discusses the incredible data that PSP collected on coronal mass ejections (CMEs) over a four-year period. This study holds the potential to help scientists and the public better understand the CMEs and how they contribute to space weather.

40 Telescopes Watched the Sun as the Parker Solar Probe Made its Most Recent Flyby

Sometimes in space, even when you’re millions of kilometers from anything, you’re still being watched.  Or at least that’s the case for the Parker Solar Probe, which completed the 11th perihelion of its 24 perihelion journey on February 25th.  While the probe was speeding past the Sun, it was being watched by over 40 space and ground-based telescopes.

Wow. Parker Solar Probe Took a Picture of the Surface of Venus

The Parker Solar Probe’s mission is to study the Sun. But the spacecraft’s instruments have nabbed some pretty impressive data on Venus, as it uses the planet for gravity assists in its ever-shrinking solar orbit.

Now, the spacecraft has captured visible light images of Venus’ surface, somehow able to peer through the shroud of clouds in the planet’s atmosphere.

This is complete bonus data that wasn’t ever expected.

Parker Solar Probe Flies Through the Sun’s Outer Atmosphere for the First Time

For the first time ever, a spacecraft has flown through the Sun’s outer atmosphere. The Parker Solar Probe passed through the out portion of the Sun’s corona in April of 2021, passing directly through streamers of solar plasma.

And by the way …. there’s video of what the spacecraft “saw.”

The Parker Solar Probe is getting pelted by hypervelocity dust. Could they damage spacecraft?

There’s a pretty significant disadvantage to going really fast – if you get hit with anything, even if it is small, it can hurt.  So when the fastest artificial object ever – the Parker Solar Probe – gets hit by grains of dust that are a fraction the size of a human hair, they still do damage.  The question is how much damage, and could we potentially learn anything from how exactly that damage happens?  According to new research from scientists at the University of Colorado at Boulder (UCB), the answer to the second question is yes, in fact, we can.

What we’ve Learned About Venus From the Parker Solar Probe

The Parker Solar Probe has been getting in a lot of extracurricular activity lately.  Originally designed to observe the Sun, the probe has been taking full advantage of its path through the solar system.  In addition to snapping pictures of comets, the probe has repeatedly focused on Venus, including capturing an image peering underneath the cloud cover of the notoriously hot world.  Now a team led by Glyn Collinson of Goddard Space Flight Center found another serendipitous discovery in the data Parker collected during its latest flyby in the summer of 2020 – the probe actually flew through Venus’ upper atmosphere, and that atmosphere appeared different than it was almost 30 years ago.

Parker Solar Probe Captured Images of Venus on its way to the Sun

Last summer, the Parker Solar Probe flew past Venus on its way to fly closer to the Sun. In a bit of a surprise, one of the spacecraft’s cameras, the Wide-field Imager for Parker Solar Probe, or WISPR, captured a striking image of the planet’s nightside from 7,693 miles (12380 km) away.

The surprise of the image was that WISPR – a visible light camera – seemingly captured Venus’ surface in infrared light.

Parker Solar Probe Gives a Unique Perspective on Comet NEOWISE

Comet watchers have enjoying the newly-discovered NEOWISE comet since it was first spotted in March 2020. Now that it’s visible with the naked eye, in dark sky conditions, all kinds of Earthly observers are checking the visitor out.

But NASA’s Parker Solar Probe has another view of the comet, one denied to Earth-bound observers.
