The samples, a highlight of Sci Power for Future Thailand Fair, will be on display at the Queen Sirikit National Convention Center until July 28. The exhibition invites the public to discover the technological and innovative achievements resulting from cutting-edge astronomical challenges.

"My students and I are all very excited to see the lunar soil. It is the first time that we are so close to the moon," said Tippawan Boonkaew, a high school teacher who led dozens of students from Bangkok's neighboring province of Nonthaburi to see the exhibition on Tuesday.

She said the lunar soil samples were much smaller than they had expected, but were still very impressive. "Also, we are very happy and proud that China chose Thailand to be the first destination to exhibit the lunar soil," she added.
