Tweet the International Space Station on the solstice, June 21, 2014

On the heels of the nanosatellite project (see this June 19, 2014 posting) here’s an email announcement about a very interesting project for the Summer Solstice (June 21, 2014),

The June Solstice (Saturday, June 21) is the best time to view the International Space Station [ISS] in the northern hemisphere.

But now there¹s another way.

Crowdsource the pictures via Twitter.

Space enthusiasts are being encouraged to tag their tweets with #SpotTheStation and include a location name and it will go on an interactive map.

Astronaut Reid Wiseman had the idea while on the International Space Station.  His tweet for example was ³During #Exp40, spot the #ISS & tweet your town, country-or-state w/ #spotthestation (pics welcome); we’ll map it! bit.ly/SpotTheStation2²

Here’s a little more detail as to the company and agency behind this project,

Esri, a GIS mapping software provider, has partnered with the Center of Geographic Sciences in Canada to develop a Twitter app to pinpoint the exact location of the ISS sightings around the world in order to give a complete view. The global map documenting the recent ISS sightings is already live.

I have looked at the live map and tweeters have been active. You can check to see the locations. For example, as of June 19, 2014 1000 hours PDT, Canada has some 26 tweets while Florida has 40 and Munich tops them both with 132 tweets.

I have looked up the company, Esri, and found this on the About Esri History page,

Jack and Laura Dangermond founded Esri in 1969 as a small research group focused on land-use planning. The company’s early mission was to organize and analyze geographic information to help land planners and land resource managers make well-informed environmental decisions.

There’s a very interesting article on the Esri website, which provides some insight into the origins for the June 21, 2014 ‘#SpotTheStation’ project. Written by Carla Wheeler (an Esri writer), it is undated but there is mention of Chris Hadfield’s sojourn on the ISS and his attendance at an event in June 2013 after he landed. From Wheeler’s 2013 (?) article, A Map App Odyssey,

Today social media, with doses of humor, are very much a part of the space mission, with the National Aeronautics and Space Administration (NASA), the Canadian Space Agency (CSA), and many astronauts sending messages, videos, and photos back to Earth via Twitter, Facebook, and YouTube. Followers post messages for the astronauts too, making interaction about space interactive.

The photos Hadfield and fellow ISS astronaut Thomas Marshburn sent via Twitter inspired their follower David MacLean, a faculty member at the Centre of Geographic Sciences (COGS), Nova Scotia Community College, and his students to create a mapping app called Our World from the ISS. It used Esri ArcGIS Online to map more than 950 photographs of interesting places on Earth that Hadfield and Marshburn shot from space. They took the photos during their December 2012–May 2013 mission and posted the images on Twitter with their observations of each scene (in 140 characters or fewer, of course). Hadfield, a Canadian, was especially prolific and poetic. …

MacLean, also a Canadian, was intrigued by the astronauts’ unique perspective as they orbited 400 kilometers (250 miles) above earth, photographing everything from cities to barrier reefs and sand formations to smoke from brush fires. He didn’t want their geologically and geographically interesting images and descriptions—such as “taffy-twisted African rock” and the “yin and yang of ice and land”—to quickly get swallowed and lost in the fast-moving Twitterverse.

“[Hadfield] took pictures all over the earth, with wonderful prose as he described the outback of Australia and parts of Mauritania and Algeria that no one would [otherwise] get to see,” MacLean said. “Unfortunately, Twitter seems to be a very temporal medium, and all these wonderful pictures—these rich resources—slip away and you have to really look to find them.”

MacLean wondered if there was a way to preserve the images and messages in the Tweets in a form that was easy for people to find and view. He decided to try building a mapping app, which he and his students created using geographic information system (GIS) technology from Esri, online comma-separated value (CSV) files, and Google Docs spreadsheets in Google Drive. Their map displays icons, provided courtesy of the Canadian Space Agency, that look like small space stations. These show the approximate (or, at times, quite accurate) locations of each photograph. Viewers can pan the map, zoom in to any area of interest, and tap an icon. A pop-up window will appear that includes a thumbnail of the picture and the message from the astronaut. You can also click the thumbnail to see the full-size Tweet in the astronauts’ Twitter feed. (Clicking the photo in Twitter will then bring up a larger, sharper image.) It’s a little like seeing photos of landscapes in National Geographic—only taken from space.

Tap an icon north of Medina, Saudi Arabia, to see Hadfield’s May 3 [2013?] photo of the Harrat Khaybar volcanic lava field and read his post: “The Earth bubbled and spat, like boiling porridge, long ago in Saudi Arabia.” Another geologic wonder caught his eye Down Under: “A splash of dry salt, white on seared red, in Australia’s agonizingly beautiful Outback.”

So, on June 21, 2014 get ready to tweet ‘#SpotTheStation’ and have a joyous Summer Solstice!
