So here is a guessing game for your Friday morning: What are the three states that have not had residents make a contribution to help refurbish the iconic Saturn V rocket in Huntsville?

The rocket, the only standing mock-up of the Saturn V rocket that took men to the moon, is getting an overhaul at the U.S. Space & Rocket Center.

The museum – the state's top tourist attraction – is sprucing up the towering 363-foot rocket for the July celebration of the first moon landing 50 years ago.

The museum launched a $250,000 fundraising campaign last month to help pay for the project, which is expected to cost about $1.3 million.

The rocket, built in 1999 for the 30th anniversary of the first moon landing, is undergoing its first top-to-bottom restoration.

Donations can be made at rocketcenter.com/revive.

And those donations have been rolling in, according to a tweet Thursday by the museum. The figurative glass should be considered, mathematically-speaking, well over half full.

But if you've received donations from 47 states, hey, might as well try to make it all 50.

“Hawaii, Vermont, Wyoming! Where are you?” the museum tweet said. “You are the last three states we’re missing from #RevivetheSaturnV!”
