After 45 days in transit, Blue Ghost is finally ready for the big show: attempting to make a soft touchdown on the moon.

It’ll be far from easy, as the vehicle must stay in control as it attempts to slow down from thousands of miles per hour to make a precision touchdown — while avoiding troublesome craters and rocks.

Here are the key moments to watch for:

• 63 minutes before touchdown: Blue Ghost conducts its “descent orbit insertion.” That an engine burn that will place the vehicle on a trajectory down toward the moon’s surface.

• 62 minutes before touchdown: Blue Ghost will begin a “coast phase” as its navigation systems keep a close eye on its orientation and position relative to the moon.

• 11 minutes before touchdown: Blue Ghost will ignite all of its thrusters and main engine to slow itself down — aiming to decrease its speed from 1.7 kilometers per second (3,800 miles per hour) to just 40 meters per second (90 miles per hour).

• 100 seconds before touchdown: Blue Ghost will hit a speed of just 1 meter per second (2.2 miles per hour) as precision thrusters steer its final descent.

• TOUCHDOWN: This is set to occur at 2:34 a.m CT (3:34 a.m. ET). Firefly is expected to give confirmation of a safe landing within minutes — if the spacecraft has a smooth arrival.

• 30 minutes after touchdown: Firefly expects to begin sharing Blue Ghost’s first images from the lunar surface.
