Space is popular once more! With SpaceX finally bringing astronauts to the Space Station from American soil, billionaires launching themselves into low-earth orbit, and a new space race back to the moon and on to Mars, it seems like space is on everyone's mind once again.

That means dressing up as an astronaut will be a popular choice for Halloween in 2021. You can dress up as a traditional NASA astronaut, or get a totally different interstellar look that uses non-traditional colors or styles. Here are some great astronaut costume options for Halloween 2021.

Traditional Orange ACES Astronaut Flight Suit Costumes

Did you know that shuttle astronauts wore International Orange flight suits during ascent as a safety precaution in case of emergency? The bright color is extremely visible against a variety of natural landscapes, especially the ocean. Here are some orange NASA-style astronaut flight suit costume ideas.

White EVA-Style or Heat-Reflective Astronaut Costumes

White jumpsuits are worn during EVAs, or spacewalks, to protect astronauts when they are exposed to space outside of their vehicle. White is also worn to help keep astronauts from overheating, as the light color reflects rather than absorbs heat from the sun. Here are some white NASA-style astronaut costume jumpsuits.

Other Fun Astronaut Costume Ideas

These unique spaceflight-inspired costumes are funny, or have a different look besides the traditional jumpsuits familiar to fans of NASA astronauts. These outfits can be used alongside traditional costumes as a couple, friend, family, or group costume idea.

The Falcon and the Winter Soldier was a hit Marvel Cinematic Universe (MCU) series for Disney+ when it was released early in 2021. The series followed the two title characters as they worked together following the events of Endgame. It depicted the transformation of the Captain America character from Steve Rogers to Sam Wilson, and showed how Bucky Barnes, the Winter Soldier, was dealing with the abuses of his past. In the end these two characters found a heroic continuation to both of their stories.

Kids who are fans of Marvel superheroes will love dressing up as these hot members of the Avengers. Get two friends or siblings together to play the heroic pair together.

Copy the look of the famous "We Can Do It!" propaganda poster with this empowering costume. Dress like World War II cultural icon Rosie the Riveter, a timeless symbol of the inspiration of wartime effort.

The iconic poster artwork by Howard Miller was commissioned by the Westinghouse Company to inspire their wartime factory workers. Originally only displayed on company grounds for two weeks during February 1943, the poster came to wider fame much later when it was rediscovered in the 1980s. 

The illustration features a young working woman. She wears a denim shirt, and bandana of red with white polka dots in her hair. She holds up a fist and shows off a muscular arm, depicting the strength and resilience of workers during the wartime effort at home.
