The European and Japanese team behind the BepiColombo mission to Mercury has shared the first image of the spacecraft’s recent flyby of the distant planet.
The black-and-white image shows the planet in incredible detail, its surface pockmarked by numerous craters from billions of years of asteroid and comet bombardment.
Hello again Mercury!
Here's a first look from today's #MercuryFlyby capturing such an amazing array of the planet's rich geological features 🤩https://t.co/hC6TfMmCy1#ExploreFarther pic.twitter.com/7WkYiGU0Kp

It was captured by the mission’s Mercury Planetary Orbiter from around 570 miles (920 kilometers) above the planet’s surface on June 23. The European Space Agency (ESA) noted that the spacecraft made an even closer approach just five minutes before the image was taken, coming within just 124 miles (200 kilometers) of Mercury’s surface.
Parts of the Mercury Planetary Orbiter are also visible in the image. The spacecraft’s magnetometer boom, for example, can be seen running from bottom-left to top-right, and a small part of the medium-gain antenna at bottom-right is also within the frame.
Look toward the bottom-left of the image and you’ll be able to spot the 124-mile-wide (200 kilometer). multi-ringed basin, part of which is obscured by the magnetometer boom.
This week’s flyby is the second performed by the Mercury Planetary Orbiter and comes eight months after the first, which captured an image from about 620 miles (1,000 kilometers) above the planet’s surface.
“Even during fleeting flybys, these science ‘grabs’ are extremely valuable,” said Johannes Benkhoff, ESA’s BepiColombo project scientist. “We get to fly our world-class science laboratory through diverse and unexplored parts of Mercury’s environment that we won’t have access to once in orbit, while also getting a head start on preparations to make sure we will transition into the main science mission as quickly and smoothly as possible.”
The main science mission will see ESA’s Mercury Planetary Orbiter — together with Japan’s Mercury Magnetospheric Orbiter, which is also part of the BepiColombo mission — analyze Mercury’s core-to-surface processes, magnetic field, and exosphere in a bid to learn more about the origin and evolution of a planet that orbits so close to its parent star.
ESA said the observations will be “key to understanding solar wind-driven magnetospheric processes, and BepiColombo will break new ground by providing unparalleled observations of the planet’s magnetic field and the interaction of the solar wind with the planet at two different locations at the same time.”
The orbiter is currently beaming additional images to Earth, with the team expected to share them online on Friday morning. All images will be released to the public in the Planetary Science Archive on Monday, June 27, ESA confirmed.
