Moon Rocks
The first lunar base was completed last year. One company, aptly named "Out Of This World Vacations", offers tourists a week-long visit to the Moon. The cost of such a vacation is extremely high.
"It was awesome! Wait till I show you the Moon rocks I brought back," Alex boasted as a crowd gathered around him on the school grounds.
"What's going on here?" Kari whispered to the person beside her.
"Alex is telling us about his experience on the Moon."
"I felt like an Olympian; I was able to jump more than a metre straight up!" The crowd was clearly impressed so Alex continued. "There are no clouds and no light pollution from big cities, so there was an amazing view of the stars. And while you were here, possibly watching the moonrise, I watched the earthrise - right from when it was just visible on the horizon until it was overhead."
"Why should we believe you actually went there?" one sceptic asked.
"I knew there would be doubters, so I brought back a few Moon rocks. I collected these while on a moonwalk in the Sea of Tranquility. Hey, Jack, you collect rocks, this would be a stellar addition to your rock collection! I'm willing to sell you a rock for only..."
"I've heard quite enough," Kari interrupted. "Jack, save your money for your own vacation."
What had Kari heard that indicated the story wasn't true?

Hint
Have you seen the far side of the Moon?Answer
If you are standing on the Moon, you will never see the Earth rise or set. One side of the Moon always faces the Earth, while the other side always faces away. So depending on where you are on the Moon, the Earth will either always be in the sky, or never be in the sky; it will not rise or set.You may have seen the famous "Earthrise" picture; it was taken from a spacecraft orbiting the Moon. Since the spacecraft was moving around the Moon, it was able to see the Earth rise as it moved.
The other parts of the story could be true. Because of the lower gravity on the moon, you can jump about 6 times higher than on Earth. Even though they don't contain water, many craters on the Moon are called seas, so you would be able to walk in the Sea of Tranquility.

i feel special now haha
That was very fun and educational. Keep em' coming!
Clever, and quite fun. Thanks for the mind munchies!
one thing wrong with your answer. The Lunar Mare (seas) aren't craters. They are the plains or areas where evidence of craters were old crater impacts were filled in with lunar basalt from lunar volcanoes.
I thought for sure the answer would be that he claimed to see stars... with the moon's surface so bright, would you see stars at all?
$ourDough got it right without even a second thought
$D

I got this one!!!!
Cool!
interesting.
I loved this teaser! And it made me feel good that I got it right because I am only ten and most things on here are more for people who have been in school for a long time
I got this!!! I really like space teasers! There should like be a separate category for them! Loved it!
I got it too. Great story, and great explanation. Thanks again, Marc!
there are some good things to being a space nerd!!
Very nice! It reminds me of old science fiction stories about the moon. Heinlein "Have Spacesuit, Will Travel" involves tourism on the moon like in this puzzle. Also it reminds me of Arthur Clarke's book "Earthlight" (because of the title), a spy story set in a moon base.
