Just over a month into its mission, Parker Solar Probe has returned first-light data from each of its four instrument suites. These early observations – while not yet examples of the key science observations Parker Solar Probe will take closer to the Sun – show that each of the instruments is working well.
This image from the WISPR suite shows a beautiful image of the Milky Way on the left, looking at the galactic center. The bright object slightly to the right of the image's center is Jupiter.
As the only imager on Parker Solar Probe, WISPR will provide the clearest-yet glimpse of the solar wind from within the Sun’s corona. Comprising two telescopes, WISPR sits behind the heat shield between two antennae from the FIELDS instrument suite. The telescopes were covered by a protective door during launch to keep them safe.

WISPR was turned on in early September 2018 and took closed-door test images for calibration. On Sept. 9, WISPR’s door was opened, allowing the instrument to take the first images during its journey to the Sun.

Parker Solar Probe’s first close approach to the Sun will be in November 2018, but even now, the instruments are able to gather measurements of what’s happening in the solar wind closer to Earth.
