The best test of General Relativity, by 2 misplaced satellites.  A launch mishap led to the experimental confirmation of gravitational redshift.

“Disclaimer: It is arguable what is THE best test of general relativity because there are different ways to test the theory. This is the best confirmation of gravitational redshift, which is one of the three original tests proposed by Einstein.”
