How Engineers Are Practicing for the BepiColombo Mission to Mercury (Video)

Within just six months, the European Space Agency (ESA) and the Japan Aerospace Exploration Agency are planning to launch a new mission to Mercury called BepiColombo — but they're already acting like the mission has launched.

That's because the team is simulating a whole range of conditions to make sure that once the spacecraft leaves Earth, everything will go as smoothly as possible, no matter what happens, as they explain in a new video released by ESA.

It may seem odd to practice for a mission that will become reality soon enough, particularly when the two space agencies have plenty of other projects in the works. But because so many things can go wrong during a space mission, preparation is crucial.

"The failures can be anything," Elsa Montagnon, BepiColombo's operations manager, said in the video. "The failures can be a problem on the spacecraft, a problem on the ground, it can be a problem with computers, a problem with ground software, communication lines, ground stations, control rooms here, it can even be a problem with the operators themselves."

So, until August, ESA scientists and engineers are using a replica of the spacecraft and its computer to practice for perilous situations on the long flight, like instruments getting overheated as it flies closer to the sun.

Then, all the practice will become reality once BepiColombo launches between Oct. 5 and Nov. 29 of this year. The spacecraft will take seven years to reach its destination: orbit around Mercury. After the long journey, it will separate into two orbiters peeling off to study the tiny planet's geology, atmosphere and magnetosphere.
