What are Artemis 2 astronauts eating in space?
05 Apr 2026

NASA recently shared a video from the Orion spacecraft on its Artemis II lunar mission.

The footage features astronauts Reid Wiseman, Christina Koch, and Jeremy Hansen enjoying a meal in microgravity.

To the delight of many, Commander Wiseman confirmed that even on a Moon mission, space has mac and cheese.

How do they eat in space?
Microgravity meals

In microgravity, where people and objects seem weightless, eating becomes a complicated engineering challenge.

This is because there's no gravity to keep food on a plate. So, all food is stored in sealed plastic or metallic pouches.

Koch, who spent almost a year on the International Space Station (ISS), explained most meals are rehydrated by adding water to dried food until it absorbs moisture and becomes edible again.

Safety precautions

In a spacecraft, crumbs don't fall; they float. These tiny particles can enter an astronaut's eye or get sucked into sensitive equipment and cables, causing a short circuit.

That is why food like the spicy green beans and macaroni shown by the Artemis II crew must be stable and crumb free.

NASA has also ensured that their menu is far from boring, with 189 unique items including barbecued beef brisket and mango salad.

Culinary innovation

The meals on the Artemis II mission are thermostabilized, meaning they're heat-treated to kill harmful bacteria and stay safe for years without refrigeration. This is especially important for deep space travel.

Despite the challenges of space travel, comfort remains a priority.

As the crew flies over the lunar surface, a warm pouch of cauliflower mac and cheese offers a much-needed psychological boost.
