The ESA/JAXA BepiColombo mission has made its second gravity help of planet Mercury, capturing new close-up photos because it steers nearer in the direction of Mercury orbit in 2025.
The closest strategy came about at 09:44 UTC (11:44 CEST) on June 23, 2022, about 200 km (124 miles) above the planet’s floor. Photos from the spacecraft’s three monitoring cameras (MCAM), together with scientific information from numerous devices, have been collected through the encounter. The MCAM photos, which give black-and-white snapshots in 1024 x 1024 pixel decision, have been downloaded over the course of yesterday afternoon, and a variety is offered right here (click on photos to increase captions for extra particulars).
A phenomenal sequence of 56 photos taken by the monitoring cameras on board the ESA/JAXA BepiColombo mission because the spacecraft made its second shut flyby of its vacation spot planet Mercury on June 23, 2022.
“We've accomplished our second of six Mercury flybys and shall be again this time subsequent 12 months for our third earlier than arriving in Mercury orbit in 2025,” says Emanuela Bordoni, ESA’s BepiColombo Deputy Spacecraft Operations Supervisor.
As a result of BepiColombo’s closest strategy was on the planet’s nightside, the primary photos through which Mercury is illuminated have been taken at round 5 minutes after shut strategy, at a distance of about 800 km (500 miles). Photos have been taken for about 40 minutes after the shut strategy because the spacecraft moved away from the planet once more.

As BepiColombo flew from the nightside to dayside, the Solar seemingly rose over the cratered floor of the planet, casting shadows alongside the terminator – the boundary between evening and day – and highlighting the topography of the terrain in dramatic trend.
Jack Wright, a member of the MCAM staff, and a analysis fellow based mostly at ESA’s European House Astronomy Centre (ESAC) in Madrid, helped to plan the imaging sequence for the flyby. He mentioned: “I punched the air when the primary photos got here down, and I solely obtained increasingly more excited after that. The pictures present stunning particulars of Mercury, together with considered one of my favorite craters, Heaney, for which I recommended the identify a number of years in the past.”

Heaney is a 125 km (78 mile) huge crater lined in easy volcanic plains. It hosts a uncommon instance of a candidate volcano on Mercury, which shall be an necessary goal for BepiColombo’s high-resolution imaging suite as soon as in orbit.
Just some minutes after closest strategy and with the Solar shining from above, Mercury’s largest impression function, the 1550 km (960 mile) huge Caloris basin swung into view for the primary time, its highly-reflective lavas on its ground making it stand out towards the darker background. The volcanic lavas in and round Caloris are thought to post-date the formation of the basin itself by 100 million years or so, and measuring and understanding the compositional variations between these is a crucial aim for BepiColombo.
“Mercury flyby 1 photos have been good, however flyby 2 photos are even higher,” commented David Rothery of the Open College who leads ESA’s Mercury Floor & Composition Working Group and who can be a member of the MCAM staff. “The pictures spotlight lots of the science objectives that we are able to tackle when BepiColombo will get into orbit. I need to perceive the volcanic and tectonic historical past of this superb planet.”

BepiColombo will construct on the info collected by NASA’s Messenger mission that orbited Mercury 2011-2015. BepiColombo’s two science orbiters – ESA’s Mercury Planetary Orbiter and JAXA’s Mercury Magnetospheric Orbiter – will function from complementary orbits to check all facets of mysterious Mercury from its core to floor processes, magnetic subject, and exosphere, to higher perceive the origin and evolution of a planet near its guardian star.
Despite the fact that BepiColombo is at present in ‘stacked’ cruise configuration, which means many devices can't be totally operated through the temporary flybys, they will nonetheless seize insights into the magnetic, plasma, and particle atmosphere across the spacecraft, from areas not usually accessible throughout an orbital mission.

“Our instrument groups on each spacecraft have began receiving their science information and we’re trying ahead to sharing our first insights from this flyby,” says Johannes Benkhoff, ESA’s BepiColombo venture scientist. “It will likely be attention-grabbing to check the info with what we collected on our first flyby, and add to this distinctive dataset as we construct in the direction of our predominant mission.”
BepiColombo’s predominant science mission will start in early 2026. It's making use of 9 planetary flybys in complete: one at Earth, two at Venus, and 6 at Mercury, along with the spacecraft’s photo voltaic electrical propulsion system, to assist steer into Mercury orbit. Its subsequent Mercury flyby will happen on June 20, 2023.
