The French “Microscope” orbiter will try to poke a hole in one of Einstein’s most famous theories, which provides the basis for our modern understanding of gravity. Scientists will use the kit to measure how 2 different pieces of metal—one titanium and the other a platinum-rhodium alloy—behave in orbit.
“In space, it is possible to study the relative motion of two bodies in almost perfect and permanent free fall aboard an orbiting satellite, shielded from perturbations encountered on Earth,” said Arianespace, which put the satellite into orbit on Monday.
Einstein’s theory suggests that in pe...
