# Why astronauts pack hot sauce: Tabasco and four others flew on Artemis II

Weightlessness dulls the sense of taste, so NASA's food scientists send bold flavours along, a habit with a long history on the space station.

**HOUSTON, USA, April 8, 2026 —** NASA sent five hot sauces on Artemis II.[^1] The lineup was Tabasco, Cholula, Frank's RedHot, Heinz Hot Taco Sauce and Sriracha.[^2] The astronauts chose them together with NASA's food scientists,[^3] and NASA says it does not endorse any of the brands.[^4]

None of them is extreme. Cholula is the hottest of the five, at around 3,600 Scoville heat units, and Frank's RedHot the mildest, at 450.[^5][^6]

Why pack them at all? Microgravity dulls astronauts' sense of flavour.[^7] In orbit, body fluids shift toward the head and cause nasal swelling and congestion, which makes food taste blander[^8][^9] and can cut flavour perception by 70 percent.[^10] Strong hot sauces help make up for it.[^11][^12]

The craving is nothing new on the space station. Many astronauts want spicier, more tart food in orbit,[^13] and in 2002 astronaut Peggy Whitson joked about barring a visiting shuttle crew from the station over a spicy resupply.[^14] Freeze-dried shrimp cocktail is a station favourite.[^15] Other foods change too: astronaut Douglas Wheelock said green beans tasted like grass in space[^16] and sliced strawberries tasted repulsively sweet.[^17] NASA spends about two years developing each approved space dish.[^18]

**Space Nugget.** Most of what we call taste is really smell. The tongue picks up only a few basics, such as sweet, salty, sour, bitter and savoury; the rich detail of a flavour comes from aromas reaching the nose. The burn of chilli works differently: capsaicin triggers heat and pain sensors in the mouth, which is why spicy food still registers when a blocked nose mutes almost everything else.
