Preparing for Mercury BepiColombo smoke-stack completes testing

ESA’s Mercury booster has upheld a final exam in launch configuration, a final time it will be built like this before being reassembled during a launch site subsequent year.

BepiColombo stack

BepiColombo’s dual orbiters, Japan’s Mercury Magnetospheric Orbiter and ESA’s Mercury Planetary Orbiter, will be carried together by a Mercury Transport Module. The conduit will use a mixed of electric thrust and mixed gravity-assists during Earth, Venus and Mercury to finish a 7.2 year tour to a Solar System’s puzzling innermost planet.

Once during Mercury, a orbiters will apart and pierce into their possess orbits to make interrelated measurements of Mercury’s interior, surface, exosphere and magnetosphere. The information will tell us some-more about a start and expansion of a world tighten to a primogenitor star, providing a improved bargain of a altogether expansion of a possess Solar System.

To ready for a oppressive conditions tighten to a Sun, a booster have undergone endless contrast both as apart units, and in a 6 m-high launch and tour configuration.

One set of tests carried out progressing this year during ESA’s technical centre in a Netherlands focused on deploying a solar wings, and a mechanisms that close any row in place. The 7.5 m-long array of a Mercury Planetary Orbiter and a two 12 m-long array of a Mercury Transport Module will be folded while inside a Ariane 5 rocket.

Last month, a full booster smoke-stack was tested inside a acoustic chamber, where a walls are propitious with absolute speakers that imitate a sound of launch.

Just final week, tests mimicked a heated vibrations gifted by a satellite during launch. The finish smoke-stack was jarred during a operation of frequencies, both in up-down and side-to-side motions.

BepiColombo’s tour to Mercury


These were a final tests to be finished with BepiColombo in automatic launch configuration, before it is reassembled again during a launch site.

In a entrance weeks a public will be distant to ready a send procedure for a final exam in a thermal–vacuum chamber. This will check it will withstand a extremes of temperatures en track to Mercury.

The final ‘qualification and acceptance review’ of a goal is foreseen for early March. Then BepiColombo will be flown to Europe’s Spaceport in Kourou, French Guiana, in credentials for a Oct 2018 depart window. The date will be reliable after this year.

“This week was a final event to see a booster in a built launch pattern before it leaves Europe. The subsequent time will be when we are during a launch site already fueled,” says Ulrich Reininghaus, ESA’s BepiColombo Project Manager. “This is utterly a miracle for a plan team. We are looking brazen to completing a final tests this year, and shipping to Kourou on schedule.”
