This would be the last launch of the Delta IV Heavy from Vandenberg, As well as the last launch of a Delta rocket out of California. The last two flights will fly out of Cape Canaveral in Florida.

Yes good question folks ?, a Heavy vehicle like this you would think NASA would want if they have plans for the ‘Gateway” space station around the moon in the future . More ‘Heavy” lifting vehicles for their payloads the better to choose from .?
