With the nearly full moon shining overhead, two companies, one American and the other headquartered in Japan, launched privately-developed robotic lunar landers early Wednesday, sharing a sky-lighting ride to space atop a SpaceX Falcon 9 rocket.

Firefly’s Blue Ghost — named after a species of U.S. Southeastern fireflies — should reach the moon first. The 6-foot-6-inches-tall (2-meter-tall) lander will attempt a touchdown in early March at Mare Crisium, a volcanic plain in the northern latitudes.
