Space is a curious place, and although there’s no air to breathe, experts say the smells are out of this world,according to a recent report from Space.com.
Thanks to the use of helmets, astronauts don’t have to really deal with many of the more pungent aromas hanging around the universe. However, once they’re back inside their spacecrafts and can safely remove their helmets, the smells can get interesting.
“Space definitelyhas a smell that’s differentthan anything else,” astronautDominic “Tony” Antonellisaid in 2009.
Those who participated in the Apollo moon landing or who have worked at the International Space Station have gone on record to report that the lunar landscape is rife with thesmell of gunpowderand “burnt steak,” per Space.com.
“Everyone’s instant impression of the smell was that of spent gunpowder,” Apollo 17’s Harrison “Jack” Schmitt, who walked on the moon in 1972, previously told the outlet. “Spent gunpowder smell probably was much more implanted in our memories than other comparable odors.”
“It reminded me of my college summers where I labored for many hours with an arc welding torch repairing heavy equipment for a small logging outfit,” NASA astronaut Don Pettit once wrote in ablog post. “It reminded me of pleasant sweet smelling welding fumes.”
