Space-traveling plush toys may seem unusual, but they have quietly been a part of human spaceflight for decades. Missions undertaken by organizations like NASA and companies like SpaceX often include small soft mascots inside spacecraft cabins.
These objects are known as zero gravity indicators. They begin to float once the spacecraft leaves Earth’s gravity and enters microgravity. This simple movement provides astronauts with an immediate visual cue about a change in the environment.This tradition goes back to early space missions, including Vostok 1. Over time, this tradition has been continued through lunar programs such as Artemis 2 and modern commercial flights.
What started as a practical idea gradually became a familiar and constant element across generations of space exploration.
Plush amulets used in space missions
Height: Amulet of Artemis II
PC: Columbia One
Rise (plush toy) is a white plush mascot chosen for the Artemis II mission. Designed by a young creator and featuring a hat decorated with Earth, galaxies and rocket-shaped details. The amulet is placed inside the spacecraft cabin next to the crew.It serves a functional role during flight. When the spacecraft emerges from Earth’s gravitational pull, Rays begins to float freely inside the cabin.
This movement provides astronauts with clear and immediate visual confirmation of microgravity conditions. The body is lightweight and easy to monitor, making it suitable for this purpose. The use of Rise is a continuation of the long-standing practice of including a visual indicator to identify transitions in spaceflight environments, maintaining consistency with previous missions.
Baby Yoda: Journey of the Merchant Crew
Computer: Space
According to Space.com, Baby Yoda was on board a SpaceX mission to the International Space Station.
This plush toy has become popular due to its wide popularity and unique image. It was placed in the cabin before take-off. During the flight, Baby Yoda was used as an indicator of microgravity conditions. Once the spacecraft entered microgravity, the toy began to float, notifying the crew. This indicates that the spacecraft successfully entered orbit.This choice of mascot is very practical because the toy is easily recognizable and, at the same time, it is suitable according to the informal practice of bringing some soft toys to show the gravity transitions.
Snoopy: Longtime NASA icon
Snoopy has been associated with NASA from the late 1960s onwards. Snoopy participated in flights related to the lunar exploration mission, such as Apollo 10. Eventually, Snoopy evolved into part of the bigger picture when it came to NASA’s spaceflight awareness campaigns. Snoopy, in his plush form, has served many duties as a zero-gravity indicator. Once the spacecraft enters microgravity, the mascot will float in the cabin.
Snoopy’s constant presence on various shows shows that she has remained constant all this time.
Shaun the Sheep: Artemis’s First Mission
Computer: Space
As reported by the BBC, Shaun the sheep was included in the unmanned Artemis I mission aboard the Orion spacecraft. The amulet was placed inside the capsule before launch and remained on board throughout the mission’s journey around the Moon and back.Prior to the mission, the titular character was taken through various training and familiarization activities throughout Europe and the United States.
These steps were part of mission preparation and public engagement efforts. Once the spacecraft reached space, Sean floated inside the cabin, acting as a zero-gravity indicator. Its motion provided a simple visual reference for the spacecraft’s transition into microgravity.
Dinosaur Tremor: SpaceX’s experimental mission
As Space.com reported, Tremor the Dinosaur was flown aboard a SpaceX Crew Dragon demonstration mission. The plush dinosaur features an embroidered design, making it a visual standout inside the spacecraft cabin.
During the mission, the tremor served as an indicator of zero gravity. When the spacecraft reached microgravity, the toy began floating freely, confirming the change in gravitational conditions for the crew. Its movement was easy to notice due to its reflective surface and shiny appearance.The use of Tremor follows the same pattern seen in other quests involving stately indicators. A small, lightweight object is selected, placed inside the cabin, and allowed to float once in space.
Why is it important to carry stuffed toys into space?
Plush animals may be considered fun things, but their presence on spacecraft is no coincidence. Such objects, as used by companies like NASA and SpaceX, among others, act as zero-gravity detectors. When a spacecraft breaks away from Earth’s gravitational field, the toy will begin to float, thus acting as a visual indicator that zero gravity has been reached.The movement of such toys helps astronauts ensure that zero gravity occurs without relying too much on technological means. In fact, games are commonly used because they can communicate what they are intended to communicate very clearly.
