The ion engines are only about nine inches around ... braking against the sun’s pull until the craft orbits Mercury. Chemical rockets, obviously, have a much greater thrust but use 10 to 20 ...

Diving into one of the most mesmerizing and mysterious elements on the periodic table: Mercury (Hg). Known for being the only ...

The clever bit is that, unlike chemical rockets ... "BepiColombo's seven year trip to Mercury will include 22 ion thrust arcs – and we absolutely need healthy and well performing thrusters ...

so researchers have developed various mercury sensors. One of these was integrated into a glove for on-site monitoring, but it couldn’t detect the ion in small amounts and required a constant supply ...

A team of researchers might have found just the right material to efficiently remove mercury -- even at low levels -- from contaminated bodies of water. Researchers estimate that mercury emissions ...

Levels of mercury persist in tuna, decades after pollution controls were introduced to limit emissions, scientists say. The poisonous element is released by mining and burning coal and ends up in ...
