Watch the closest flyby of a planet ever, because the ESA/JAXA BepiColombo spacecraft sped previous Mercury throughout its newest encounter on 4 September 2024.
This flyby marked BepiColombo’s closest method to Mercury but, and for the primary time, the spacecraft had a transparent view of Mercury’s south pole.
This timelapse is made up of 128 totally different pictures captured by all three of BepiColombo’s monitoring cameras, M-CAM 1, 2 and three. We see the planet transfer out and in of the fields of view of M-CAM 2 and three, earlier than M-CAM 1 sees the planet receding into the space on the finish of the video.
The primary few pictures are taken within the days and weeks earlier than the flyby. Mercury first seems in a picture taken at 23:50 CEST (21:50 UTC) on 4 September, at a distance of 191 km. Closest method was at 23:48 CEST at a distance of 165 km.
The sequence ends round 24 hours later, on 5 September 2024, when BepiColombo was about 243 000 km from Mercury.
Throughout the flyby it was doable to determine varied geological options that BepiColombo will research in additional element as soon as in orbit across the planet. 4 minutes after closest method, a big ‘peak ring basin’ known as Vivaldi got here into view.
This crater was named after the well-known Italian composer Antonio Vivaldi (1678–1741). The flyover of Vivaldi crater was the inspiration for utilizing Antonio Vivaldi’s ‘4 Seasons’ because the soundtrack for this timelapse.
Peak ring basins are mysterious craters created by highly effective asteroid or comet impacts, so-called due to the inside ring of peaks on an in any other case flattish flooring.
A few minutes later, one other peak ring basin got here into view: newly named Stoddart. The identify was just lately assigned following a request from the M-CAM staff, who realised that this crater can be seen in these pictures and determined it might be price naming contemplating its potential curiosity for scientists sooner or later.
BepiColombo’s three monitoring cameras supplied 1024 x 1024 pixel snapshots. Their primary objective is to watch the spacecraft’s varied booms and antennas, therefore why we see elements of the spacecraft within the foreground. The pictures that they seize of Mercury through the flybys are a bonus.
The 4 September gravity help flyby was the fourth at Mercury and the seventh of 9 planetary flybys total. Throughout its eight-year cruise to the smallest and innermost planet of the Photo voltaic System, BepiColombo makes one flyby at Earth, two at Venus and 6 at Mercury, to assist steer itself heading in the right direction for coming into orbit round Mercury in 2026.
BepiColombo is a global collaboration between ESA and JAXA.

Processing notes: The BepiColombo monitoring cameras present black-and-white, 1024 x 1024 pixel pictures. These uncooked pictures have been processed to take away digital banding within the cameras. The M-CAM 1 pictures have been cropped to 995 x 995 pixels
