The Parker probe is transiting the Sun, which is an image that is a sure message to another planet that Earthlings are busy.
During its nominal mission lifetime of just under 7 years, Parker Solar Probe will complete 24 orbits of the Sun — reaching within 3.8 million miles of the Sun's surface at closest approach.
The Sun is about 8.3 light minutes from the Earth. This means it would take 8.3 minutes for light to reach from the Surface of the Sun to reach the Earth. If you are traveling in a Jumbo Jet, it would take you about 19 years to reach the Sun.
On the final three orbits, Parker Solar Probe will fly to within 9 solar radii of the sun's "surface" 9 solar radii is 9 times the radius of the sun or about 3.83 million miles. That is about seven times closer than the current record-holder for a close solar pass, the Helios spacecraft.
At closest approach, Parker Solar Probe will be hurtling around the sun at approximately 430,000 miles per hour! That's fast enough to get from Philadelphia to Washington, D.C., in one second.
At closest approach to the sun, while the front of Parker Solar Probe' solar shield faces temperatures approaching 1,400° Celsius, the spacecraft's payload will be near room temperature.
This is what other advanced civilizations will see, a manmade object crossing the path at over 400,000 miles per hour. It will be easy to read for others.
Note about transits and our work.
Moreover, it’s meant to be sensitive to small changes in the amount of light emitted by objects, as it usually looks for the dim light changes caused planets passing in front of distant stars.
