President Joe Biden made a decorating choice that has the space community abuzz: There's a moon rock in the Oval Office.

"Thank you to ⁦@POTUS for putting a @NASA⁩ moon rock in the Oval Office - look at what we can do together as a country when we are united," Ellen Stofan, the John and Adrienne Mars Director of the Smithsonian’s National Air and Space Museum, said on Twitter.

"In symbolic recognition of earlier generations’ ambitions and accomplishments, and support for America’s current moon to Mars exploration approach, a moon rock now sits in the Oval Office of the White House," NASA said in its news release.

Meenakshi Wadhwa, director of Arizona State University's School of Earth and Space Exploration, can't wait until a Mars rock is returned to Earth to be placed alongside the moon rock (NASA's Perseverance rover is set to collect samples from Mars, and a future mission could return these samples).

"I am loving how excited my timeline is that there's a Moon rock in the Oval Office," said planetary science Ph.D.

But the little  moon rock gave hope to many seeking a vigorous pursuit of space exploration
