Instrument WISPR (Wide-Field Imager) sondy Parker Solar Probe podczas 2. ostatnich przelotów (3.i 4.) koło planety dostarczył pierwszych zdjęć planety w świetle widzialnym.
Parker Solar Probe Captures its First Images of Venus' Surface in Visible Light, ConfirmedFeb 9, 2022
As Parker Solar Probe flew by Venus on its fourth flyby, its WISPR instrument captured these images, strung into a video, showing the nightside surface of the planet. Credits: NASA/APL/NRL(...) Smothered in thick clouds, Venus’ surface is usually shrouded from sight. But in two recent flybys of the planet, Parker used its Wide-Field Imager, or WISPR, to image the entire nightside in wavelengths of the visible spectrum – the type of light that the human eye can see – and extending into the near-infrared.
The images, combined into a video, reveal a faint glow from the surface that shows distinctive features like continental regions, plains, and plateaus. A luminescent halo of oxygen in the atmosphere can also be seen surrounding the planet. (...)
“We’re thrilled with the science insights Parker Solar Probe has provided thus far,” said Nicola Fox, division director for the Heliophysics Division at NASA Headquarters. “Parker continues to outperform our expectations, and we are excited that these novel observations taken during our gravity assist maneuver can help advance Venus research in unexpected ways.” (...)
