How to Send Your Own Message to the iPad on Artemis 1 As It Orbits the Moon

NASA recently successfully launched Artemis 1, an unmanned mission working towards mankind’s return to the moon. The capsule is now orbiting the moon with no astronauts on board but with an iPad. Now NASA is offering people the ability to send a message to this iPad as Artemis 1 orbits the moon.

A brief overview of Artemis 1 and the Callisto project

NASA launched Artemis 1 as part of its effort to send humans back to the moon. The Orion capsule, which will eventually carry the crew, will undergo various tests and experiments. Among them is the Callisto project for testing human-machine interfaces in space.


In the Orion capsule, NASA uses an iPad, the video conferencing software Cisco Webex and a special Deep Space version of the language assistant Amazon Alexa. On the ground, NASA personnel issue commands to Alexa using the iPad installed in the Artemis-1 capsule. In return, they will test how well the custom-built Deep Space Network can work with Alexa.

Side project allows people to send messages to the world through Artemis 1 iPad

As one of many side experiments, NASA is opening the Artemis 1 mission to do a bit of public relations. You can submit your own message, which will be displayed on the iPad inside the space capsule, via the project website or the Explore Orion app.

There is of course no guarantee that the team will choose your message. Lockheed Martin is conducting the experiment and has the final say on which messages are displayed and which are not.

Once submitted, your message will be reviewed and selected for display at Lockheed Martin’s sole discretion. Messages with derogatory, defamatory, racist, sexist or otherwise inappropriate content will be automatically rejected. Messages that contain copyrighted material or endorse people, products, brands, etc. will also be automatically rejected.

Other than that, it’s fun to try. With replays of messages from inside the spacecraft available for download, you may have the opportunity to discover your own message as it travels to, from, or around the moon.

How to send your message to the Orion spacecraft

There are two ways you can submit your own message for review. You can fill out a form on the Lockheed Martin website for the Callisto project. Your message can be up to 120 characters long and you can choose how you want your name to appear on screen.

Communicate with the Callisto website

Alternatively, you can use the Explore Orion app on your iPhone to submit your message. After launching the app, tap the bottom menu icon and select Callisto.

Send a message to Callisto using the Explore Orion app

Next, tap Talk to Callisto at the bottom of the display. Fill out the form and submit it. Lockheed Martin will review your message and it may appear in a replay video.
