NASA's Parker Solar Probe Just Started Its First Skim Past the Sun

NASA's Parker Solar Probe has had a big week: on Monday (Oct. 29) it broke two world records and on Wednesday (Oct. 31) it began its first close pass over the sun.

That maneuver is the first of 24 planned science encounters with the sun, which will last until 2025. This time around, the spacecraft will reach its closest point to the sun on Nov. 5 at about 10:28 p.m. EST (0328 GMT on Nov. 6), according to NASA.

At that point in its voyage, the spacecraft will be just 15 million miles (24 million kilometers) from the surface of the sun and will be traveling at 213,200 mph (343,000 km/h).

During the flyby, the Parker Solar Probe will be unable to communicate with Earth because the sun produces such enormous amounts of radio waves that they will drown out the spacecraft's signals. But the probe is designed to take care of itself, autonomously troubleshooting problems and twisting to stay safe from the sun's overwhelming heat.

And all the while, the spacecraft's instruments will be working to crack the mysteries of the sun that powers our every moment here on Earth. Four different sets of instruments will study the structure of the star's outer atmosphere, which scientists call the corona. We may even get our first image from within that corona, thanks to a camera aboard the spacecraft that's already snapped an incredible picture of Earth during its journey.

There's just one catch: Because of the probe's alignment, scientists won't get the data from this week's observations for a few more weeks.

Thanks fieldmarshaldj. It was developed by Peter Parker, and the live video will be fed to the Web. /rimshot

“to stay safe from the sun’s overwhelming heat.”

Why don’t they go at night?

World Record?? Maybe an out-of- World record ...

Lol! Good point.
