Dramatic Video Shows the Closest Flyby Ever of Mercury

A brace of Mercury probes got up adjacent and idiosyncratic with the star system’s underdog planet, revealing its cratered aboveground successful a recently released video of the otherworldly encounter.

The European Space Agency (ESA) released a 90-second video of BepiColombo’s caller flyby of Mercury, which marked the closest attack to the innermost planet. The footage is made up of 128 images, stitched unneurotic to nutrient a cinematic timelapse of the spacecraft’s caller rendezvous.

BepiColombo carried retired its 4th gravity assistance of Mercury connected September 4, approaching the planet’s cratered aboveground astatine the closest region of 102 miles (165 kilometers) astatine 5:48 p.m. ET. During its speedy visit, the spacecraft utilized its 3 onboard monitoring cameras to seizure elaborate views of the planet, revealing its mysterious craters. BepiColombo besides had its archetypal wide presumption of Mercury’s southbound pole.

The archetypal fewer images shown successful the video were taken successful the days and weeks earlier the flyby, arsenic the spacecraft journeyed done the interior star strategy connected its mode to find Mercury. BepiColombo approached Mercury from the planet’s nightside, with the Sun illuminating its cratered aboveground arsenic the spacecraft drew nearer. The satellite archetypal appears astir 10 seconds into the video, its cratered aboveground emerging from the darkness.

Around 4 minutes aft the spacecraft’s closest attack to Mercury, the planet’s mysterious craters came into view. One of the craters, which measures astir 96 miles crossed (155 kilometers), got its sanction successful grant of the anticipated flyby. The crater was fixed the sanction Stoddart by the International Astronomical Union aft Margaret Olrog Stoddart, an creator from New Zealand known for her angiosperm paintings.

The series of Mercury photos shown successful the video ends astir 24 hours aboriginal connected September 5, with the satellite appearing successful the region arsenic the spacecraft bids farewell.

BepiColombo launched successful October 2018 arsenic a associated ngo betwixt the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA). Each abstraction bureau provided an orbiter to research Mercury’s surface, interior, and magnetic field. ESA’s Mercury Planet Orbiter (MPO) and JAXA’s Mercury Magnetosphere Orbiter (MMO) launched unneurotic connected a azygous spacecraft, and each are designed to participate its respective orbit astir Mercury.

BepiColombo is lone the 3rd spacecraft to sojourn Mercury, the slightest explored rocky satellite of the star system, according to ESA. Mercury is particularly tricky to scope owed to the Sun’s almighty gravitational pull, which accelerates the spacecraft towards it.

In bid to scope Mercury, the spacecraft has to execute 9 gravity assistance maneuvers successful total: 1 astir Earth, 2 astir Venus, and six astir Mercury. The ngo carried retired its archetypal flyby of Mercury successful October 2021 and returned gorgeous close-up images of the star system’s smallest planet. BepiColombo is scheduled to participate Mercury’s orbit successful November 2026.
