It's lights out for the first private lunar lander to pull off a fully successful moon mission. Firefly Aerospace's Blue Ghost lander fell silent over the weekend, wrapping up two weeks of science experiments for NASA.

"Per aspera ad astra! Love, Blue Ghost." The Latin phrase-which roughly translates to "through hardships to the stars"-closes out the final lunar transmission from the Blue Ghost lander, which according to developer Firefly Aerospace achieved the "longest commercial operations on the moon to date" during its approximately two-week mission.
