Apollo 15's Secret Space Mail!

Imagine getting a letter from the Moon! That's kind of what happened with the Apollo 15 mission. Three brave astronauts, David Scott, Alfred Worden, and James Irwin, secretly brought about 400 special envelopes with them.

These weren't just any envelopes; they had stamps and were postmarked, like a special souvenir from space! They were even taken to the Moon's surface inside their spaceship, the Lunar Module Falcon.

These special envelopes weren't supposed to go on the trip! The astronauts hid them in their spacesuits. They were supposed to be a surprise for a stamp collector. Each astronaut was promised about $7,000, which is a lot of money, like buying a whole playground! They planned to sell these Moon envelopes when they got back home. It was like bringing back a super rare toy from a faraway land.

When NASA, the space agency, found out about the secret envelopes and the plan to sell them, they were not happy! It was like getting in trouble at school for doing something you weren't supposed to. The astronauts had to give back the money they were promised. Even though they were heroes who went to the Moon, this mistake meant they couldn't go on any more space missions.

Even though the astronauts got in trouble, these special envelopes are still super interesting! Some of them were sold for a lot of money, more than a brand new car! One of these 'Moon envelopes' was even sold for over $50,000. It shows how special and rare anything that has been to the Moon really is. It's a little piece of space history!
