Organizing a Watch Party

Watch parties are a fun and informal way to bring together space fans and the public to experience the excitement of space exploration. Enjoying a milestone moment in spaceflight can be entertaining and educational and creates a great opportunity to share The Planetary Society’s mission with more people.

Here are some general tips for organizing an event around a launch, landing or other space exploration milestone.

Who to invite

The most obvious guests are the people you already know. Invite your friends and family, or anyone you know who is interested in space exploration. If you want to make the event open to other people as well, you will need to promote it. Here’s how:

You can create an event page on Facebook or Meetup and invite attendees to register there so that you have a sense of how many people to expect. This is also a great way to provide updates and reminders in the days leading up to the event.

Where to host the party

If you decide to keep the guest list to friends and family, you could choose to do it at your own home or a friend’s home.  For a larger, more public event we definitely recommend hosting the party in a public space. If you decide to go this route, you might choose one of these:

Advance preparation

You should find out in advance how the milestone moment will be streamed. You’ll usually find a link to a stream on the space agency or company’s website, press room, or YouTube channel. The website or press room will usually tell you in advance where the stream link will be found.

Use’s converter tool to convert the time of the event to your local time zone, and double check that you have the right time. It’s easier than you might think to make a mistake. Schedule the event at least a half hour before the highlight moment is due to begin. That gives you plenty of time to meet and greet your guests.

If you’re using a public space, make sure all the technical requirements will be met. You’ll need WiFi, a projector and screen or a large TV that can connect to the internet, as well as speakers. If possible, arrange with the venue to test a week or more in advance to make sure the audiovisual equipment works.

Plan a “Run of Show.” Write down a schedule for the event and what you plan to do to fill the time before and after. If you will be hosting the event from a stage, arrange for someone to assist you with behind-the-scenes event coordination.

Remember that launches, in particular, are often delayed. Be prepared with a back-up activity like a discussion topic, a game, or something else space-related to watch. Also, be prepared in case of total audiovisual failure. What's your backup plan? Using a phone to follow Twitter and reading tweets aloud to the crowd works, in a pinch.

Leading the event

Once your attendees have arrived, welcome them to your event and give a brief description of The Planetary Society - who we are, what we do, and how they can get involved. If you really want to take this opportunity to educate your attendees, you can give a more formal presentation about TPS or about various topics in space exploration using the resources in our outreach toolkits.

Enjoy the watch party! Don’t forget to take pictures throughout the event.

When the event is over, thank everyone for coming and give your TPS pitch one more time, encouraging people to check out our website and sign up for email updates. The next day, send your attendees a thank you message or e-mail including a reference to our website and a link to sign up for email.
