NASA sent five hot sauce varieties on Artemis II, deeming the spicy staple an essential item.
Why it matters: Even in space, flavor matters.
The big picture: NASA declined to release the list of brands on the mission, but we like to think Tabasco and Sriracha made the cut.
Context: Hot sauce serves practical and behavioral health functions in space, says Victoria Segovia, a public affairs specialist at Johnson Space Center in Houston.
In microgravity, astronauts often experience a shift in their olfactory senses, which can dull flavor perceptions. "Spicy and bold" condiments help enhance taste, Segovia says.
How it works: Astronauts and NASA's food scientists help select the hot sauces.
Astronauts taste-test and provide input on flavor preferences, variety and compatibility with the menu.
Selections are evaluated for safety, shelf stability, nutritional value and suitability for the spaceflight environment.
Fun fact: Sauces on Artemis II include spicy mustard, honey and maple syrup, NASA says.
