A spacecraft bound for the planet Mercury will take a first look at the target tonight, when it makes its first-ever flyby of the small rocky world during an incredibly close encounter tonight. Space.com reports: The mission, called BepiColombo, is a joint project of the European Space Agency (ESA) and the Japanese Aerospace Exploration Agency (JAXA). It is only the second mission in history sent to orbit Mercury, the smallest and innermost planet of the solar system. BepiColombo’s flyby tonight (Oct. 1) will bring the spacecraft within just 124 miles (200 kilometers) of the surface of Mercury, the closest the probe will ever get to the planet during its mission. The first images from the encounter are expected to reach Earth early Saturday (Oct. 2) and will be the first close images of Mercury’s scorched surface since the end of NASA’s Messenger orbiter mission in 2015. BepiColombo will make its closest approach to Mercury at 7:34 p.m. EDT (2334 GMT) today (Oct.1), ESA said in a statement. The spacecraft will then continue on its winding trajectory around the sun. This close pass is one of nine gravity-assist flybys, maneuvers that use the gravity of celestial bodies to adjust a spacecraft’s trajectory, that BepiColombo needs to perform before it can enter its target orbit around the planet. This flyby, however, will take the spacecraft even closer to the scorched planet’s surface, than its ultimate scientific orbit of 300 to 930 miles (480 to 1,500 kilometers). The $750 million BepiColombo mission will be able to make measurements of the environment around the planet and take images with its black and white ‘selfie’ cameras, which provide a 1024 by 1024 pixel resolution (comparable to an early-2000s flip phone.) […] After tonight’s close pass, it will take four more flybys of Mercury by BepiColombo before the spacecraft is in the correct position to finally enter the planet’s orbit, which is set to happen in 2025.Read more of this story at Slashdot.
