Robotic vehicles from Firefly Aerospace of Texas and Ispace of Japan parted ways early Wednesday after being launched on the same SpaceX rocket. Both are aiming for the lunar surface.

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.
