Ariana Grande stopped by NASA's Johnson Space Center in Houston, Texas the day before her concert in that city. She even wore an astronaut suit and carried a helmet while touring the facilities. The 25-year-old pop star obviously had a great time because she openly expressed her gratitude to the NASA center.


"Thank you for the coolest day of my life @nasa," she wrote on Instagram. "My mind is still processing and devouring every second of what just happened but I can't wait to share more. What a special day and experience. Thank you so so so so much for your generosity and for showing my friends n i around."


Before putting on the space suit, Grande popped on a skull cap, a necessary part of the astronaut's outfit and only one part of an incredibly complicated ensemble. But Grande laughed and was in high spirits the whole time.

During the NASA visit, Grande met with astronomers, signed some NASA equipment and video-chatted with astronauts on the International Space Station. After, she also took a ride in a roving vehicle.


The Space Center also recognized the pop star by playing the song "NASA" from Grande's most recent album Thank U, Next. The song opens with lines from RuPaul's Drag Race alum Shangela, who says: "This is one small step for woman, one giant leap for womankind."


The Johnson Space Center also welcomed the pop singer with a sign on the Mission Control saying: "Welcome to Mission Control Ariana Grande." From all the Instagram videos, it was clear everyone was having a great time and NASA looked proud to be hosting the iconic dangerous woman.
