A joint European-Japanese spacecraft has had its first glimpse of Mercury as it swung by the solar system’s innermost planet while on a mission to deliver two probes into orbit in 2025.

The BepiColombo mission made the first of six flybys of Mercury at 9.34am Saturday AEST, using the planet’s gravity to slow the spacecraft down.

After swooping past Mercury at altitudes of less than 200km, the spacecraft took a low resolution black-and-white photo with one of its monitoring cameras before zipping off again.

The European Space Agency said the captured image shows the northern hemisphere and Mercury’s characteristic pock-marked features, among them the 166km-wide Lermontov crater.

The joint mission by the European agency and the Japan Aerospace Exploration Agency was launched in 2018, flying once past earth and twice past Venus on its journey to the solar system’s smallest planet.

Five further flybys are needed before BepiColombo is sufficiently slowed down to release ESA’s Mercury Planetary Orbiter and JAXA’s Mercury Magnetospheric Orbiter.

The two probes will study Mercury’s core and processes on its surface, as well as its magnetic sphere.

The mission is named after Italian scientist Giuseppe ‘Bepi’ Colombo, who is credited with helping develop the gravity assist manoeuvre that NASA’s Mariner 10 first used when it flew to Mercury in 1974.
