Science is making a comeback! Cool new discoveries came about in 2019, like the first image of a black hole that scientists have been able to obtain. They were also able to detect earthquakes on Mars! (No sign of aliens yet, but we're crossing our fingers.) All of this exciting space news has rekindled the interest in space exploration…which has also sparked new interest in Astronaut costumes! Children have always been enamored by the idea of space travel, so it's not really a surprise that some of our kids’ astronaut costumes are picking up a lot of steam this year. We recommend our exclusive costumes made by our in-house designers. They're a cut above the rest and give a realistic look for any aspiring young space adventurer. We know that adults dream of space exploration too, which is why our adult astronaut costumes are great for anyone who had a dream of piloting a rocket ship in their youth!
