In early April, as the European-Japanese BepiColombo spacecraft was approaching our home planet ahead of the first flyby in its seven-year journey to Mercury, mission scientists invited amateur astronomers to observe the event from Earth and share their photos of this unique event.

Over thirty observers from around the world participated in the campaign. The jury, composed of BepiColombo mission experts, was very positively impressed by all entries, both on aesthetical grounds and because of the good quality of the astronomical observations, and wishes to thank all participants who observed the Mercury explorer as it crossed our sky and immortalized it in their beautiful images and sequences.

The authors of the three best images of the flyby – the best glimpse, the best track and the last glimpse – selected by the jury will receive a scale model of BepiColombo.

The winning images are:

  • a view of BepiColombo passing through a deep sky object – the Blue Horsehead Nebula – taken in the early hours of 10 April by Sergio Silva in Porto Feliz, São Paulo, Brazil, which was selected as the ‘best glimpse’ of the flyby;
  • a sequence of images of BepiColombo moving through a stellar field, featuring a ‘guest’ appearance of a piece of space debris – a decommissioned geostationary satellite – captured in the evening of 10 April from the Northolt Branch Observatories by Guy Wells and Daniel Bamberger in London, UK, which was selected as ‘the best track’ of BepiColombo during its passage above the horizon;
  • a parting view of the spacecraft, a dot against the tracks of distant stars, taken on 19 April from the Rikubetsu Space and Science Museum observatory in Ashoro District, Hokkaido, Japan, which was selected as the best ‘last glimpse’ of BepiColombo from Earth.

The jury also acknowledges the following contributions with a special mention: Gianluca Masi, Virtual Telescope Project; Alain Maury, Jean Marc Mari and Joaquin Fabrega; Inoue Takeshi; Kenichi Shirakami; Masanori Mizutani; T. Oribe, Saji Observatory; Nicolas Biver.

BepiColombo reached its closest approach to Earth at 04:24:57 UTC on 10 April, flying only 12 689 km above our planet’s surface. The manoeuvre – the first of nine planetary flyby and the only one of Earth – tightened the spacecraft’s orbit towards the inner Solar System, where it is scheduled to meet Venus on 15 October for the first of two flybys of this planet on the way to Mercury.
