Plush toys traveling in space may seem unusual, yet they have quietly been a part of human space flight for decades. Missions conducted by organizations like NASA and companies like SpaceX often include small soft mascots inside spacecraft cabins. These objects are known as zero gravity indicators. As soon as a spacecraft leaves Earth’s gravitational pull and enters microgravity, they begin to float. That simple activity provides astronauts with an immediate visual signal about changes in the environment.This tradition dates back to early space missions, including Vostok 1. Over time, this has continued through lunar programs such as Artemis II and modern commercial flights. What started as a practical idea has gradually become a familiar and consistent element across generations of space exploration.
Plush mascots used in space missions
Rise: Artemis II mascot
PC: ColumbiaOne
Rise (plush toy) is a white plush mascot selected for the Artemis II mission. It was designed by a young creator and features a cap adorned with Earth, galaxies, and rocket-themed details. The mascot is placed with the crew in the cabin of the spacecraft.It plays a functional role during flight. When the spacecraft leaves Earth’s gravitational influence, Rise begins to float freely inside the cabin. This activity provides astronauts with clear and immediate visual confirmation of microgravity conditions. The object is light and easy to see, making it suitable for this purpose. The use of RISE continues the long-standing practice of including a visual indicator to mark changes in the space flight environment, maintaining consistency with earlier missions.
Baby Yoda: Commercial Crew Flight

According to Space.com, Baby Yoda was aboard a space mission sent by SpaceX to the ISS. This plush toy became popular due to its widespread recognition and unique image. It was placed in the cabin before lift-off. During the voyage, Baby Yoda was used as an indicator of microgravity conditions. As the spacecraft entered microgravity conditions, the toy began to float, alerting the crew. This indicated that the spacecraft successfully entered orbit.Such a choice for the mascot is quite practical because the toy is easily recognizable, and at the same time, it is appropriate according to the informal practice of bringing some soft toys to demonstrate gravity transitions.
Snoopy: Longtime NASA Symbol
Snoopy has been associated with NASA since the late 1960s. Snoopy was involved in flights related to lunar exploration missions such as Apollo 10. Ultimately, Snoopy has become part of the bigger picture when it comes to NASA’s spaceflight awareness campaigns. Snoopy in his plush form has served as a zero gravity indicator in several missions. As the spacecraft entered microgravity, the mascot would begin floating around in the cabin. Snoopy’s continued presence on various programs shows that it has remained consistent throughout time.
Shaun the Sheep: Artemis I Mission

Shaun the Sheep was included in the unmanned Artemis I mission aboard the Orion spacecraft, the BBC reports. The mascot was placed inside the capsule prior to launch and remained onboard throughout the mission’s journey around the Moon and back.Prior to the mission, the plush character was taken through various training and introduction activities throughout Europe and the United States. These steps were part of the mission’s preparation and public engagement efforts. Once the spacecraft reached space, Shawn began floating inside the cabin, acting as a zero gravity indicator. Its motion provided a simple visual reference for the spacecraft’s transition into microgravity.
Tremor the Dinosaur: SpaceX Demo Mission
The Tremor dinosaur was carried on a SpaceX Crew Dragon demonstration mission, Space.com reports. The plush dinosaur has a sequined design, making it visually stand out inside the spaceship cabin. During the mission, Tremor served as a zero gravity indicator. As the spacecraft reached microgravity, the toy began to float freely, confirming to the crew the change in gravity conditions. Its movement was easy to observe due to its reflective surface and shiny appearance.The use of Tremor follows the same pattern seen in other missions with plush indicators. A small, lightweight object is selected, placed inside the cabin, and allowed to float once into space.
What is the significance of taking plush toys to space?
Plush animals may be considered fun items, but their presence on spacecraft is not accidental. Such objects, used by NASA and other companies like SpaceX, act as zero-gravity detectors. When a spacecraft separates itself from Earth’s gravitational field, the toy will begin to float, serving as a visual indicator that zero gravity has been reached.The movement of such toys helps astronauts confirm that zero gravity has occurred without relying too much on technical means. In fact, toys are commonly used because they can communicate very clearly what they want to convey.
