Wave with us!

Update 11th March 2014

We’re still so pleased to see so many people still waving at the ISS – thank you all for tweeting about it and spreading the word.

We’re also delighted to see that National Geographic has joined in with its own #HelloFromEarth and #LiveFromSpace Program – http://channel.nationalgeographic.com/channel/live-from-space/.

If you haven’t for a while, get out there and wave at the humans in space!

Update 10th September 2012

Although the “official” ISSWave was way back in 2010, we’re so pleased to see that many people are still waving and using the hashtag #ISSwave. We’re happy to keep the site running, as long as you keep waving.

The website sadly got hacked, and we lost a lot of our waves from the map. However, everything is now back working (thanks to @Terrazoom).

To register your wave on our map send a tweet in the following format (not including the brackets):

[any text] #ISSwave [zip/postal code OR city] [country name or three letter code]

Wishing  you all clear skies!

The ISSWave Team

Update (12/24): Following a steep first day learning curve, we’ve modified the instructions below to help you make sure your waves are registered on our map.

ISS Wave is a round-the-world wave to the humans aboard the International Space Station (ISS) by their fellow humans on the Earth – choreographed by a grassroots Twitter campaign (@ISSwave).

ISS Wave will take place 24-31 December, 2010. Join us in this expression of human solidarity during the holidays by following these simple steps:

1. Plan your wave

The International Space Station has been orbiting the Earth over 15 times a day for more than ten years. Although it is about 390 km high, we can still see it from the Earth, thanks to the Sun reflecting off the solar arrays. There are various ways you can work out when it will be possible to see it from where you are, including Heavens Above, Twisst, NASA, ESA, Over Twitter and Real-Time Satellite Tracking. You might also check your local weather forecast. The ISS is bright, but not bright enough to be seen through the clouds!

If pass timings and/or weather conditions don’t work out for you, please still wave and share your wave (see below). You don’t have to be able to see the ISS to know it’s passing overhead. On Heavens Above, you can see all passes — visible and invisible — by clicking “All passes of the ISS”.

2. Invite tweeps, friends and family

Of course you can wave alone (the whole point is that you’re not alone, after all!), but why not invite tweeps, friends and family to wave with you? There are some good festive group waving opportunities including bright passes over the US East Coast, the UK and Europe on New Year’s Eve. Host your own ISS Wave Tweetup or just recruit your fellow revelers wherever you may be to come outside and wave!

3. Tweet* your wave

The point of ISS Wave is to express solidarity with our fellow humans on Earth and aboard the ISS. Make sure your wave is registered on our map for all to see by posting a tweet in the following format (not including the brackets):

[any text] #ISSwave [zip/postal code OR city] [country name or three letter code]

“[any text]” may include thoughts, holiday wishes, photos, videos, etc. It’s important that the last three elements of your tweet are the hashtag, location and country otherwise our map might not recognise your tweet! Double check the text of your tweet before posting by entering it in the box at the bottom of the map page.

*Not on Twitter? Not a problem! Share your wave with us by email and we’ll tweet it for you. Please use subject line “ISS Wave Tweet” and include the following in the body of your email:

  • #ISSwave
  • postal/zip code OR city
  • country
  • (optional) notes, thoughts, holiday wishes, and photos or videos of your wave (as attachments)

And remember, this is for Twitter, so all this needs to be 140 characters or less!
