Do the #ISSWave All the Way Around the World

C’mon, admit it. If you regularly watch for the International Space Station passing overhead you’ve probably waved or shouted a greeting as it sailed high above you. I regularly salute the ISS, even though I know the astronauts on board can’t see or hear me. But still.

Well, it turns out I’m not alone. Through Twitter, other people have found out that it is pretty common for people to wave at the ISS. So now, as a “celebration of human solidarity during the holiday season” a group of Twitters have organized “ISSWave.” For one week beginning Friday, December 24 through December 31, humans around the world can wave together and show their solidarity with their fellow humans in space (and on Earth) by waving at the ISS as she passes overhead at 28,000 kph (17,500 mph).

You can share your waves on Twitter — either alone or as part of an ISSwave tweetup (a physical gathering of twitterers, or tweeps) — by tweeting your zip/postal code and the hashtag “#ISSwave” along with photos and videos of their waves, thoughts, holiday wishes for the astronauts and cosmonauts, etc. Participants’ waves will be registered in real-time at www.isswave.org.

Astronauts and cosmonauts aboard the International Space Station may even film themselves waving back at ISSwave participants. At least two astronauts, including Ron Garan, have voiced their support for ISSwave in emails and tweets.

How did this idea come about? Well, the organizers are Lucy Rogers (@DrLucyRogers), Richard P. Grant (@rpg7twit) and Karen James (@kejames). The idea for the wave emerged through a serendipitous twitter exchange among the three, and they discovered that watching ISS passes is even more exciting when done together with other humans, whether they are standing right next to you or watching from afar. To know that you are not the only one looking up in awe at this spectacle of human ingenuity and cooperation speeding across the night sky creates a special connection between us.

“The first time I watched an ISS pass I was surprised by how much it affected me,” said Karen James. “‘We made that’, I thought, ‘there are humans up there!’ All of my worries just seemed so tiny in the face of this symbol of human achievement and cooperation. I want to share that experience with other humans and also show my support to the ones living and working aboard the station.”

‘“I’d always wave up at the ISS if I saw it pass overhead,” said Lucy Rogers. “Someone laughed and said the astronauts wouldn’t see me.” So she asked on Twitter if anyone else waved – a lot of people did – and the communal ISS waving began. “When Karen moved to the USA she saw the ISS at a different time to us in Europe – which prompted the idea of a round-the-world wave,” she says.

We see the ISS because it is lit by the Sun. Sunlight reflects off it’s solar panels in the same way it glints off windows here on Earth. As the ISS travels round the world, the reflection can be seen in a broad sweep across the Earth. Due to the angles involved between the Sun, ISS and our location on Earth, sometimes we see bright, high passes and sometimes we can’t see it at all. During the week 24th – 31st December, most places on the Earth should get a good view of it at some point.

The three formed the Twitter account @ISSwave to coordinate, promote and provide updates on the event. Their hope is that seasoned and novice ISS watchers alike will experience the startlingly emotional experience of an ISS pass, amplified by solidarity with thousands of others watching around the world.

They also have a website, where you can find out how to see the ISS in your location, as well as find more info about joining the #ISSWave.

The team hopes the buzz around ISSwave will persuade those who have never watched an ISS pass to participate, marking an increase in awareness about the International Space Station and the existence of a community of space enthusiasts on Twitter (“spacetweeps”).

The wave also celebrates the 10th anniversary of continuous human presence in space with the ISS, which occurred on November 2, 2010 and the 50th anniversary of Yuri Gagarin’s flight into space — the first human spaceflight — on April 12th 2011 (www.YuriGagarin50.org).

    It’s a good idea – but the skyphoto shown is mirror inverted: I see Vega to the left of Altair and Deneb.
    Season greetings to all of you.

    is it correct to write 28000 kph? in europe, we write it 28000 km/h.

    Strange, but I get different viewing results on ESA, NASA and Heavens Above websites…

    I’ve always found the times on Heavens Above to be correct.
