NASA astronauts discussed how micro-gravity alters the taste of Nutella after a jar of the spread floated during a live broadcast [1].
The incident highlights the physiological challenges of deep-space travel, as changes in fluid distribution and sensory perception affect how crews consume food. Understanding these shifts is critical for long-term missions where nutrition and morale depend on palatable meals.
The Artemis II crew, consisting of four astronauts [2]—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—experienced the moment on April 6, 2024 [1]. During the livestream from inside the Orion spacecraft, a jar of the hazelnut spread drifted through the cabin. The crew later used the viral clip to engage the public in conversations about the realities of living in micro-gravity [3].
During a post-mission press conference on April 16, 2024, the crew said that the spread tasted different in the space environment [1]. This phenomenon occurs because fluids shift toward the head in micro-gravity, which can cause nasal congestion and dull the sense of smell and taste [3].
Wiseman reflected on the overall experience of the deep-space flight during the press event. "What an amazing journey that was," Wiseman said [4].
The interaction served as an informal demonstration of the Orion spacecraft's interior environment. By discussing the floating Nutella, the crew provided a relatable example of how basic human experiences, such as eating, are transformed when removed from Earth's gravity [3].
“Micro-gravity alters taste perception”
The shift in taste perception described by the Artemis II crew is a known biological response to micro-gravity. As fluids move upward in the body, the resulting congestion mimics a common cold, often leading astronauts to prefer stronger, spicier flavors to compensate for diminished sensory input. This underscores the need for specialized food engineering as NASA prepares for longer durations of human presence in deep space.
