On the agency’s Mars exploration program website, NASA details the laser retroreflector program. < / P > < p > although laser emission tests will not be carried out immediately on the will Mars Rover (and the insight lander), NASA hopes to lay some foundation for future laser based experiments. < / P > < p > unlike the Earth Moon time experiment, NASA does not intend to challenge the limits between ground fires, but plans to install lasers on future Mars orbiters to shorten the laser distance required for measurement. < / P > < p > at the same time, the European Space Agency (ESA) also plans to equip the ExoMars rover with a set of mirrors, with a target of landing on Mars in 2022. < / P > < p > as can be seen from the figure, the aurora mirror of the will rover is very compact, with a width of only 2 inches. By reflecting the light through tiny sets of mirrors, astronomers will be able to carry out measurements that were previously impossible. Chinese version of K-car: reading a10e design drawing exposure
